After reading alot of threads here about HCG, Its my understanding that high doses around 1000IUs are damaging to sertoli cells, and it was recomended that its better to do 250IU reguarly, As HMG is the FSH part, the part needed for sperm production, Is it a similar situation with dosing? Will you damage your ability to produce FSH naturally later in life, and Im also under the impression that it takes something like 70 days to produce a working sperm, would dosing need to continue for this sort of length of time? If so again the previous questions on if this would be damaging or not. Thanks guys
