Total testosterone level is 163 and free is 31.4 and my doctor prescribed axiron. are there any side effects to this relating to sperm count?

YES: When a man takes testosterone alone the brain will tell your testicles they don't have to work any more. They can atrophy, drop your sperm count to 0 and cause dry ejaculations. Furthermore, prescription topical testosterone are grossly overpriced, and diluted. They require larger surface ares to apply which can elevate Dht levels causing hair loss. I prefer HCG plus compounded testosterone.

Yes: It is important to have multiple tests of testosterone done before starting medication. They should be done in the morning. It is also important to check lh and fsh levels to see if the problem is in the testicles or pituitary/hypothalamus. Long term testosterone usage is associated with infertility since your testicles stop working.
