It's late, I just came in from an 9 hour drive, so I'm not sure if I'm following what MadRouge is saying. I have KS (Kallmanns Syndrome) and my doc recommended Gonadotropin treatment for fertility if I decided to have kids:
Gonadotropin treatment for infertility
My KS was treated successfully when I was a teenager and I continued a somewhat "normal" development biologically. Granted my adolescent years were a tad late. Only problem I have is that my sex drive (because of all the Androgel I have to pump in my body) is that of the worst 18 year old you have ever met. If I stop taking Androgel, my bones become brittle and at 6'6", I can't afford that.
The other problem is I can't have kids unless I get on the gonadotropin treatment. Which in my case is a moot point, I don't want kids.
See an endocrinologist for a full blood workup and take it from there. Good luck and ask away if you have any further questions.
