I did some genetic testing about two years ago to see my ancestry, etc, everything went as expected except I found out I'm a carrier for cystic fibrosis. I've read some about it, and almost all men with two copies are infertile, while men with one copies are sometimes affected but sometimes not. I am healthy and have never had any serious health problems I'm aware of related to CF, though my sweat has always been very, very salty compared to anyone else I've ever seen.
All of the above said, something that has been on my mind lately is that my ejaculate has always been pretty watery. It's always been greyish and watery, never thick, never white, never anything like you see in porn. A couple women I've been with have commented on it, but I never really thought much about it until recently. Apparently watery ejaculate can indicate low sperm count? Would make sense... I can't seem to find any solid data on what the rates are of infertility among CF carriers or sperm counts or anything. Anyone here a CF carrier who has had testing done or talked with a doctor about it? I'm 32 now and am considering going and having my semen tested just to know if I can have kids or not... Just think it would be a good thing to know.
