US Kallmann syndrome meeting 2013. Notes taken. Part 3.
USA Patient Meeting 2013. Notes taken. Part 3.
Obtaining
medications with health insurance.
There are companies that can provide basic testosterone
medication free of charge without insurance in the USA as long as you have a
valid prescription. There is a post in the Facebook groups listing these
companies.
Gaining hCG and hMG medications on health insurance is
possible but it is a time consuming and lengthy process. One key point is
emphasise the point that the hCG / hMG medications are required for testosterone
production only and not for
fertility. Insurance companies are very unlikely to approve medication for
fertility use. However in patients with KS / CHH the primary reason is
testosterone production and osteoporosis prevention. If you leave a message in
the Facebook groups somebody who has had a lot of experience in dealing with
insurance companies will be able to help and advice you.
Genetics.
The understanding of the genetics
of KS / CHH is changing all the time and it is difficult to give many clear cut
answers.
So far over 20 different genes
have been implicated in causing cases of KS / CHH.
With puberty being such a defining
point in human development it is not surprising there are many different genes
involved in its control. No one single gene is responsible for the initiation
of puberty so a defect in one gene does not always mean puberty is delayed or
is absent.
KS / CHH is primarily a two or
more gene defect condition, which accounts for its rarity. One gene defect on
its own might cause visible symptoms such as hearing loss, dental problems,
cleft lip, and delayed puberty. However it is only when this gene defect is
combined with another that you get a case of KS / CHH with the full range of
symptoms. It is clear by looking at families with KS / CHH that the range and
severity of symptoms is not consistent, even within siblings. This makes the
prediction of inheritance and the genetic screening for KS / CHH very
problematic.
Over 50% of KS / CHH cases still
show an unknown genetic origin. You can screen blood for the currently known
genes but any negative result just means it is negative for the genes
discovered so far. Research centres in Boston & Augusta in the USA or in
Switzerland will test blood samples for current gene defects and then store the
samples for re-testing once new gene defects are discovered.
The only exception to this is the
KAL-1 mutation on the x-chromosome. KAL-1 is termed a high penetrance gene. A
mutation in the KAL-1 gene can cause a case of KS on its own with no other gene
defect present. Any small defect in the KAL-1 gene gives rise to a high
probability of having Kallmann syndrome. The KAL-1 mutation is the one
associated with the additional symptoms of anosmia, mirror movements of the
hands, absence of one kidney and hearing loss.
KAL-1 causes x-linked KS, so is
only found in males (there is a theoretical chance of a female having x-linked
KS but has never been proved yet). X-linked KS accounts for less than 10% of
all KS / CHH cases but is the one that is most easily tested for.

USA Patient Meeting 2013. Notes taken. Part 2.
Growth spurt.
The growth spurt seen in late puberty in both males and
females is controlled primarily by testosterone and oestrogen levels under the
influence of growth hormone. Normally height will increase until the
pre-determined height is reached and then the end plates of the long bones fuse
& harden preventing any further growth.
In KS / CHH where there is a lack of testosterone &
oestrogen no growth spurt occurs but instead there is a linear height increase
under the influence of growth hormone. This can lead to patients with KS / CHH
being of above average height unless they start hormone treatment at the
appropriate time.
The lack of oestrogen or oestrogen in KS / CHH patients can
lead to early onset osteoporosis which should be checked for by the use of DEXA
/ bone density scan.
No puberty v
partial puberty.
In patients with KS / CHH it is estimated that 60% of cases
will show no pubertal development at all while the remaining 40% will show
partial pubertal development.
Use of hCG in
males.
hCG is human chorionic gonadotropin, it is normally derived
from human placentas and has the same activity as luteinising hormone (LH). In
males hCG can be given instead of testosterone preparations in order for the
testes to produce their own testosterone. Pregnyl is a common trade name for
hCG.
hCG acts on the Leydig cells in the testes in the same way
as LH, with the production of testosterone. Normal levels of testosterone can
be achieved within two months of starting treatment. Injections are given
sub-cutaneously and the dose and frequency given is dependent on the
testosterone levels achieved.
There is normally no increase in size in the testes when on
hCG injections.
There was a bit of debate at the meeting about the
possibility of achieving sperm production while on hCG alone. It is certainly
possible for some patients with KS / CHH to achieve a low level of sperm
production while on hCG injections alone but normally this tends to be the
patients who have had some form of gonadotropin treatment in the past or who
have partial testicular development already.
Patients with KS / CHH can sometimes achieving fertility
with sperm counts a lot lower than those seen in other men. The theory is that
fertility is based on the quality of sperm produced and not just the number
produced.
There is no evidence of any long term adverse risk in males
using hCG injections.
Use of FSH injections in fertility treatments in males.
Follicle stimulation hormone (FSH)
acts on the Sertoli cells in the testes in order to induce sperm production. It
is the increase in the Sertoli cells that gives the testes their size. Normally
testes need to be 4ml or bigger in order to produce enough sperm for natural
conception.
In most males, but not all, with
KS / CHH FSH type medication is required to induce fertility. It is thought
that giving FSH on its own for a few months before the addition of hCG
increases the chances of sperm production and can speed up production.
In the past hCG has been given on
its own first but new evidence suggests that pre-treatment with FSH can be more
effective.
FSH can be given in its pure form
or combined with LH in the form of human menopausal gonadotropin (hMG or
menotropin).
FSH and hMG injections are
expensive and not always easy to get hold of but can provide an effective form
of fertility treatment for me along with the psychological benefit of
testicular development.

USA Patient Meeting 2013. Notes taken. Part 1.
Gender difference
between males & females.
It used to be thought that there were about five times more
cases of KS / CHH in males than in females. This has never been fully explained
by genetics.
One school of thought is that there is actually no gender
imbalance in reality. The disproportion in diagnosed cases might well be due to
the lack of correct diagnosis of KS / CHH in females. It is not easy to
correctly diagnose KS in females, especially if the oral contraceptive pill is
used in treatment.
Un-published work done in Boston took the numbers of 600
patients in known KS / CHH families and came out with a ratio of 1 : 1.3 male
to female cases.
Definition of a
“rare disease”.
A rare disease is defined as one that is found in 1 in 2,000
of the general population. With KS / CHH being at around the 1 in 20,000 mark
roughly it falls neatly in this category. About 8% of the general population of
the USA could be classified as having a rare disease.
Start of puberty.
The age of onset of puberty has a range of 10 to 15 years in
females with a mean of 12 years old. In males the range is 12 to 16 with a mean
of 13 years old. Typically puberty takes 5 years to fully complete.
The age puberty starts in males is not easy to distinguish
in boys whereas in girls it is marked by the first menstrual bleed.
2% of the population will show a constitutional delay of
puberty. This group will start puberty naturally at some stage but early
hormonal treatment might be given in appropriate cases.
Any delay of puberty by the age of 15 in females and 16 in
males should be investigated by a reproductive endocrinologist or a paediatric
endocrinologist.
Un-descended
testes at birth.
Occurs in 2% of the male population but in up to 40% of boys
with Kallmann syndrome.
GnRH and sexual
differentiation.
Sexual differentiation into the male and female physical
forms occurs in the first few weeks of life and is controlled by the hCG
derived from the placenta. This is normally unaffected in people with KS / CHH
so they are born physically male or female.
Normally there is a GnRH surge from the hypothalamus in the
developing baby in the final trimester and into the first 6 months of life.
This is a “mini-puberty” and can give rise to detectable levels of LH / FSH /
testosterone or oestrogen. This mini-puberty is missing in patients with KS /
CHH. This can be used as a diagnostic tool for babies where there is a
likelihood of KS / CHH being passed on. This test is more sensitive in male
infants than female infants.
The presence of micro-penis and un-descended testes at birth
seen in some boys with KS / CHH is related to the lack of testosterone in boys
in this mini-puberty.

Kallmann syndrome & anosmia.
Anosmia or the lack of sense of smell is an important symptom in Kallmann syndrome as it is the one symptom that can be noticed well before the age puberty is due.
Anosmia accompanied by pubertal delay should alert doctors to the potential of a case of Kallmann syndrome.
Anosmia is only found in patients with Kallmann syndrome.
An absence of puberty and no sense of smell might not seem related at first. They are linked because the part of the brain that controls smell (olfactory bulb) and the part of the brain that controls the initiation of puberty (hypothalamus) are located very close together. During the very early development of the foetal brain any problem in the development of the structure of the olfactory bulb can prevent a the part of the hypothalamus that controls puberty from working correctly later in life.
Around 50% of cases of congenital hypogonadotropic hypogonadism (CHH) occur with a normal sense of smell. The other 50% of cases have anosmia or hyposmia (reduced sense of smell), it is these cases that can also be termed Kallmann syndrome.
Since patients with Kallmann syndrome have had no sense of smell all their lives some patients do not realise how important the sense of smell can be.
There are issues such as fire & gas safety, food wastage, personal hygiene & body odour that can be easily overlooked, especially if a person lives by themselves.
There is an excellent support group for people with all forms of anosmia, called Fifth Sense. Here is a link to their website:

Early blood test for KS / CHH - from birth to 6 months of age.
In both males and females there is a "miny puberty" which lasts from birth until 6 months of age. It is more apparent in males than females. In males it sets the body up ready for normal puberty to start at around 11 or 12 years of age.
In this short period of time from birth to six months of age there would be detectable levels of FSH and LH in the blood and detectable testosterone levels in males.
In males and females with Kallmann syndrome or CHH this miny puberty does not occur.
It works better in boys than girls but if there is a delectable level of FSH, LH, testosterone / oestrogen it would strongly suggest that it is not a case of KS / CHH.
The lack of detectable levels would not confirm a KS / CHH diagnosis but would be a big clue towards the correct diagnosis. Conversely if you do find the hormones present at that age it can be very reassuring that CHH / KS is not present.
If a blood test reveals no detectable levels of testosterone at 6 months of age and there has been either micro-penis or undescended testicles it would give doctors a very good indication that KS / CHH is a distinct possibility.
I have added here a one page link to a web site which also confirms the possibility of testing up to the age of 6 months.

Programme on CBC in America on Kallmann Syndrome.
Hopefully attached are links to three videos on AOL from an episode of "Doctors" on CBC in America where a 27 year old gets his first diagnosis of Kallmann syndrome.
They explain the basics on Kallmann syndrome very well and Brandon does an excellent job of explaining his condition.

Nebido Injection
Nebido is a long
lasting testosterone injection that is effective for treating patients with
Kallmann syndrome and CHH.
It was first developed and produced by the Bayer health
group and is licenced and distributed under the trade name Reandron 1000 in
Australia, Reandron in Spain and Nebid in Italy.
It is a 4ml injection of testosterone undecanoate that is
given as a deep muscular injection.
Two loading injections are first taken 6 weeks apart then
injections are normally given at 10 to 13 week intervals depending on the
response. Some patients enjoy the convenience of only having to have an
injection every 3 months; it is not unknown for some patients to go 6 months in-between
injections and still achieve normal testosterone levels.
Most patients achieve steady normal physiological levels of
testosterone while using Nebido, without the peaks and troughs seen with
shorter lasting injections.
It is a large volume to inject and sometimes there can be
some short lasting localised pain at the injection site but this can be avoided
by warming the vial in hot water for 5 minutes before injecting to allow the
solution to become more viscous.
The injection is widely available throughout the world apart
from the USA where under the trade name Aveed but it has yet to be licenced.

British Medical Journal article. Patient Journey - Kallmann syndrome._

The British Medical Journal todays posted an article, wrtitten by me about my story of having Kallmann syndrome.
Sunday, March 04, 2012
I was diagnosed with Kallmann syndrome at the age of 22 after spending my teenage years and early adulthood being labelled as a “late developer” or “late bloomer”.
Childhood years:
My early childhood was fairly uneventful medically apart from 70% hearing loss in one ear and no sense of smell. I reached the normal pre-puberty Tanner stages and up to the age of twelve nothing seemed to be amiss. Going through the early teenage years it was a case of waking up each day and hoping something was going to start to develop. I knew I was getting late to start puberty but I assumed it would all start soon enough. Eventually I was the only one in my year group not to show any development and was certainly noticed by the rest of the year group.
A routine health inspection by the school nurse as part of the health screen for the permit to work on a newspaper delivery round led to a referring to a GP at the age of 15. At that stage the GP said I was just late starting and I should wait and see and was sent on my way.
Teenage years:
Up to the age of 14 I was a normal enough school boy I think, I was in the Scouts and was involved in my local cricket club. I gradually got left out of social events as I lacked the confidence to go and had no sexual drive at all. I knew the basics from a purely physical point of view but had no libido or interest in any sort of teenage activities. I made up excuses not to go to social events and eventually I stopped being invited.
By the time I went to University it was obvious something was wrong but I did not have the drive to do anything about it. I even stopped taking the Sustanon for a time at University as it seemed to having no effect on me at all. Looking back now there were opportunities for me at University but without the drive and the knowledge of the condition I did not have the interest or confidence to notice them, let alone follow up on them.
On a physical level the late diagnosis has left me with osteopenia which is still present but at least not deteriorating. The lack of gonadotrophins and hence androgens in my teenage years also resulted in a delay in the development of secondary sexual characteristics. The lack of testicular development will always be present in Kallmann syndrome but the lack of penile growth will always leave the question of what would have happened if testosterone treatment had been started earlier and at the correct dose.
In my experience with fellow patients it is those who are diagnosed early and treated early who cope with the condition better. For a lot of people I talk to the very fact they can put a name to the condition and realise that they are not the only person in the world not going through puberty is a big step in being able to cope with the condition.
Referral to a reproductive endocrinologist allows for the possibility for fertility treatments. Even though there is a reported good success rate with gonadotrophin therapy for both men and women with KS there is not universal availability of treatments across the country probably due to the high cost FSH treatments.
I feel there is a good argument for FSH treatment to be available to younger men with KS even if fertility is not the ultimate goal. The testicular development achieved while on FSH can help with self confidence and emotional development.
Pregnyl / hCG can be used in isolation just for testosterone production and is useful indicator for the effectiveness of FSH treatment.
The type of hormonal replacement therapy used is also important for both men and women. The Nebido injection for men may be more suitable than the Sustanon injection due its length of action, while for some the gel, capsules or deep muscular implants may be more beneficial.
The most important treatment is possibly the diagnosis itself. Being labelled as a “late starter” or “late bloomer” when in your early twenties can be very self destructive. The ability to put a label on the condition and the knowledge that it is a recognised condition is the first step in coming to terms with a condition that is difficult to describe to others. The use of patient support groups on Yahoo and Facebook also play a big part in people being able to talk about the condition but this can only be achieved once they have got the correct diagnosis.
Kallmann syndrome is a form of hypogonadotrophic hypogonadism with the associated symptom of anosmia. It affects both men and women but is at least five times more common in men. It is a congenital condition with currently nine known gene defects linked to its cause which combined still only account for less than 40% of cases. Patients are left with poorly developed or no secondary sexual characteristics, are infertile and at increased risk of osteoporosis.

I knew the basics from a purely physical point of view but had no libido or interest in any sort of teenage activities. I made up excuses not to go to social events and eventually I stopped being invited.
By the age of 17 it was clear nothing was starting so I was referred to a general medical consultant and then an urologist at Derifford hospital in Plymouth. I was put on low dose Sustanon monthly but with no follow up assessment, it was just assumed it would all start naturally.
By the time I went to University it was obvious something was wrong but I did not have the drive to do anything about it. I even stopped taking the Sustanon for a time at University as it seemed to having no effect on me at all. Looking back now there were opportunities for me at University but without the drive and the knowledge of the condition I did not have the interest or confidence to notice them, let alone follow up on them.
Diagnosis:
The first time I actually saw an endocrinologist was when I started my first job as a Biomedical Scientist at the Royal Free Hospital in North London. I had studied endocrinology and haematology as part of my biomedical science degree and had a bit of an understanding on how puberty was supposed to work. When I started work at the Royal Free I was determined to talk to and endocrinologist even though my GP still had not referred me. Under my own volition I contacted Dr Richard Quinton, at the time a specialist registrar in endocrinology under Prof. Pierre-Marc Bouloux. One of the first questions he asked was “did I have a sense of smell”. It was the first time any doctor had asked me that question.
From there the correct diagnosis came soon after and I was put on a suitable dose of testosterone, first in the form of Testogel and then later Nebido. The delay from the age of 16 to 22 meant I went six years with a very low testosterone level with the subsequent delay in secondary sexual development and bone strength.
Blood tests then confirmed the low levels of FSH and LH which, combined with the anosmia confirmed the diagnosis. A subsequent MRI showed the absence of the olfactory bulbs. A DEXA scan showed osteopenia and I was prescribed Fosamax at the time, which has now been replaced with high dose Vitamin D therapy. At the time of diagnosis I probably looked 10 years younger than I was and never shaved.
Delay of Diagnosis.
On a physical level the late diagnosis has left me with osteopenia which is still present but at least not deteriorating. The lack of gonadotrophins and hence androgens in my teenage years also resulted in a delay in the development of secondary sexual characteristics. The lack of testicular development will always be present in Kallmann syndrome but the lack of penile growth will always leave the question of what would have happened if testosterone treatment had been started earlier and at the correct dose.
It is on the psychological level that the late diagnosis has the biggest impact in my view. Judging by my own experiences and those of fellow patients I meet and talk to now this is an area which is very frequently overlooked.
With puberty and adolescence being so closely linked if a patient does not enter puberty at almost the same stage as his peer group he risks being left behind socially and emotionally as well as physically. I feel that this emotional development of social interaction is difficult to catch up on and is often a result of feeling socially isolated when puberty fails to start.
In my experience with fellow patients it is those who are diagnosed early and treated early who cope with the condition better. For a lot of people I talk to the very fact they can put a name to the condition and realise that they are not the only person in the world not going through puberty is a big step in being able to cope with the condition.
Treatments available:
Referral to a reproductive endocrinologist allows for the possibility for fertility treatments. Even though there is a reported good success rate with gonadotrophin therapy for both men and women with KS there is not universal availability of treatments across the country probably due to the high cost FSH treatments.

What are hormones?
In a general sense hormones are the body’s messenger service. There are over 40 known hormones that act within the body. They are each released by a specific endocrine gland (such as the pituitary gland, adrenal glands, pancreas or testes / ovaries) in response to a specific stimulus, possibly another hormone. A hormone is released to generate a specific result. In normal circumstances the hormonal system works on a negative feedback mechanism.
A stimulus causes the endocrine gland to release a hormone -> The hormone causes the stimulus to be stopped or reduced -> The endocrine gland stops producing the hormone
The classic example is the role of insulin in the role of maintaining the blood sugar levels. Insulin is only released in response to an increase in sugar levels, as soon as blood sugar levels falls; the production of insulin is stopped. The breakdown in this regulation causes the most common hormonal diseases – diabetes mellitus.
In normal puberty the pathway is:
Hypothalamus gland produces GnRH (gonadotrophin releasing hormone)
Which causes the
Pituitary gland to produce LH & FSH (luteinsing hormone / follicle stimulating hormone)
Which cause the
Testes to produce testosterone & sperm
Or
Ovaries to produce progesterone and oestrogen & allow ovulation to occur
The sex hormones also have other effects around the body, not just linked to puberty and fertility.
In KS or HH either the pituitary gland does not receive the GnRH, or it is unable to respond to the GnRH. Without the first signal the pituitary will not produce its hormones (LH and FSH) that in turn will prevent the testes or ovaries producing their own hormones at the required time to cause puberty. For some people with KS / HH there is no physical problem with the testes or ovaries, they just have not had correct signal from the pituitary gland in order to function correctly.
The treatments people get with KS / HH will be replacing one of the hormones missing in the chain. Normally this is either testosterone or oestrogen / progesterone. However it is also possible to be given FSH / LH or GnRH in certain circumstances, especially if fertility is desired.
Can a person with KS or HH become fertile?
Yes, possibly, but only with specialist treatment and if other circumstances are favourable. There have been many cases of people with KS / HH having children, sometimes through a form of IVF or other assisted fertilisation programmes. As with any type of fertility treatment there are many other factors to consider and it can take many months of treatment and there is no guarantee as with any form of fertility treatment. It has been noted that fertility can be achieved with Kallmann’s women more quickly than with other patients.
Is there any effect on expected lifespan?
There is no reliable evidence that KS or HH has any effect on the life span on an individual. It is worth point bearing in mind though that there are some rare symptoms that can occur with KS and HH that may have an effect on life span. These other symptoms may be connected to KS or HH or may have arisen regardless.
Are there any risks if KS or HH is left untreated?
Yes there can be. The major problem with a person with untreated KS or HH is the increased risk of osteoporosis or ‘brittle bone disease’. The greatly reduced levels of sex hormones seen with KS and HH have a detrimental effect on the strength of the bones. This can be easily treated with the appropriate drugs that will reduce the risk of osteoporosis to that seen in the rest of the population. It is advised that a person with KS or HH should have a bone scan (DEXA) at least every 5 years to assess their bone age and to assess the risk of osteoporosis. There is increasing evidence that Vitamin D levels play a vital role general health, not just bone strength. It is not unknown for people with KS / HH to have their Vitamin D levels monitored and prescribed tablets if the level is too low.
In a general sense hormones are the body’s messenger service. There are over 40 known hormones that act within the body. They are each released by a specific endocrine gland (such as the pituitary gland, adrenal glands, pancreas or testes / ovaries) in response to a specific stimulus, possibly another hormone. A hormone is released to generate a specific result. In normal circumstances the hormonal system works on a negative feedback mechanism.
A stimulus causes the endocrine gland to release a hormone -> The hormone causes the stimulus to be stopped or reduced -> The endocrine gland stops producing the hormone
The classic example is the role of insulin in the role of maintaining the blood sugar levels. Insulin is only released in response to an increase in sugar levels, as soon as blood sugar levels falls; the production of insulin is stopped. The breakdown in this regulation causes the most common hormonal diseases – diabetes mellitus.
In normal puberty the pathway is:
Hypothalamus gland produces GnRH (gonadotrophin releasing hormone)
Which causes the
Pituitary gland to produce LH & FSH (luteinsing hormone / follicle stimulating hormone)
Which cause the
Testes to produce testosterone & sperm
Or
Ovaries to produce progesterone and oestrogen & allow ovulation to occur
The sex hormones also have other effects around the body, not just linked to puberty and fertility.
In KS or HH either the pituitary gland does not receive the GnRH, or it is unable to respond to the GnRH. Without the first signal the pituitary will not produce its hormones (LH and FSH) that in turn will prevent the testes or ovaries producing their own hormones at the required time to cause puberty.

A patient’s perspective:
“Long term psychological effects of delayed diagnosis of Hypogonadotrophic Hypogonadism in patients with delayed puberty”.
Delayed Puberty. Rosen, DS, Foster C. Pediatrics in Review 2001;22;309
While the majority of these individuals will go on to experience normal puberty, albeit a couple of years later than their peer group; there is a perhaps a need to evaluate all patients who appear to be delayed to eliminate other causes for their pubertal failure.
One possible cause of a delay or absence of puberty is Kallmann syndrome (KS) and other forms of hypogonadotrophic hypogonadism (HH). Most cases are not detected as adolescents, even if they display the anosmia seen in KS. Both KS and HH show variable physical symptoms even within family members, which in addition to the absence of a clear cut genetic test make diagnosis of KS and HH problematic at times.
Combined KS and HH have a probable incidence of approximately 1 in 4,000 males and 1 in 25,000 females. Without treatment patients will remain infertile with no or poorly defined secondary sexual characteristics and be at increased risk of developing osteoporosis.
From a patient’s point of view I feel there is a need to ensure that any adolescent with pubertal delay should be referred on for an endocrinology review. The benefits of early diagnosis and treatment of KS / HH both on a physical level and on a psychological level cannot be overestimated. An early endocrine review will be able separate a case of normal constitutional delay of puberty from a case which will require extra investigation.
From my own personal experience and from conversations with others in patient support groups the label of “late bloomer” or “late developer” can lead onto deeper psychological issues later in life as patients get left behind both physically and emotionally from their own peer group.
The social isolation some patients feel can be avoided by early diagnosis and treatment. It is clear from conversations within our support groups the earlier a diagnosis is made and the correct treatment started the more beneficial it is to the patient in later life. The ability to put a name to the condition would at least allow the patient to know there is a reason for the absence of puberty and they are not alone with the condition.

"Puberty is considered to be clinically delayed if sexual maturation has not become apparent by the age of 14 years in boys or age 13 years in girls."
"Using these criteria, approximately 2.5% of healthy adolescents will be identified as having pubertal delay"

Being able to talk to other people with Kallmann syndrome and hypogonadotrophic hypogonadism makes a lot of difference to how a person copes with having the condition.
Since the condition is so rare and it involves an area which is difficult to talk about people with KS can feel very isolated and feel like they are the only person with the condition.
The ability to contact, talk to and meet other people with the condition is almost always a very worthwhile exercise.
There are 2 groups on Facebook where you can contact other people.
One is called "Kallmann's syndromers". It is an open group where you can post comments and ask questions. There is also a chat option to talk to other members. Other people on your Facebook profile will see you are a member of this group.
http://www.facebook.com/#!/groups/114162694465
If you wish to remain totally anonymous there is an also a private, "secret" KS group on Facebook which is only visible to members and people can post and chat in the knowledge that only people in the group can see the posts in the groups. Nobody on your profile will see that you are a member of the group. You can gain entry to the group by asking one of the current members to let you in, or send me an e-mail.
There is also a contact group on Yahoo containing some members very knowledgeable on KS.
http://health.groups.yahoo.com/group/kallmanns-syndrome
I am always happy to hear from new people and will try to pass on contact details if other people want to get in touch.

Kallmann syndrome and other forms of hypogonadotrophic hypogonadism are rare conditions. It is some times very difficult to find primary physicians or GP's who have even heard of the condition.
Sometimes even when we are treated by consultants in hospitals we might be the only patient with KS or HH that they are seeing at that time.
It is sometimes difficult to find reliable information on the condition. Partly this is due to the fact that there is so much still to learn about the genetic causes of KS / HH. However there is information to be gained on the current diagnosis and treatments available for KS / HH.
One area is the number of different forms of testosterone treatments available now. A lot of people I speak to seem to be unaware of the different forms of treatments that are available. Some will work better than others and will suit different people.
There are a number of good websites about where you get information and some forum groups where you can talk to other people with Kallmann syndrome. I have left some links to some below. A lot of people with KS or HH find it very helpful to be able to talk to fellow patients. The majority of people with the condition will have never met anybody else with the condition and there can be a big advantage in meeting with and talking to other people who have gone through similar situations and know how you feel.
I talk to a lot of people with Kallmann syndrome through MSN messenger or Facebook and am always happy to talk to new people or try to introduce them to other people they may wish to talk to.

A review article on Kallmann syndrome.
This may be only of interest to those people with KS or HH but this article from Clinical Endocrinology 2010; 72(6) gives a very good overview of the diagnosis & treatment of the condition.
It is authored by Prof. Pierre Bouloux at the Royal Free hospital in London, who is my specialist and one of the first doctors to diagnose me when I worked there back in the 1990's.
By the time I left university I still was not diagnosed correctly, still labelled a "late developer" which at 21 seemed more than a bit annoying. It was only by chance that my first job after university was in the blood transfusion lab at the Royal Free Hospital in London. Prof. Bouloux and his senior registrar at the time, Dr Richard Quinton (now consultant in Newcastle) were both working at the Royal Free and specialised in treating people with KS / HH.
The fact I managed to start work at the very hospital that contained the two specialists who could diagnose me correctly was certainly a strange coincidence. The first question Dr Quinton asked me was "can I smell ". Such a simple question at the time, but none of my previous specialists or GP's had ever asked it before.
It was the first time a name was put to the condition, and a couple of months later I met somebody else with the condition for the very first time. It is difficult to put into words to people who don't have the condition the sense of relief knowing that it is a recoginsed condition, it has a name you can put to it and there are other people out there with the same condition.
