It's simple physiology and science.
When your balls atrophy you don't produce sperm and if the atrophy is permitted to remain, it becomes permanent.
Additionally, if your HPT is hit long enough and steps aren't taken to make LH and FSH you might also lose that ability, too.
19 nors are shown to inhibit nerve growth in the HPT which is why it shuts you down so hard.
Even so, if you then are low there is a protocol using clomid and ana which will get you kids. I developed it and have the lab tests and two kids to prove it works. Others have used it as well.
Reports? Yea, numerous studies are out there studying BB's having kids. Arnold's got them and numerous pro's do.
I didn't even hear any of this, I just made it up so sleep well!
BTW, your slick statement is worded incorrectly because I DID NOT say that AS will NOT affect the ability. I said that if you know what you are doing, you can avoid problems. Don't try to twist the discussion, but thanks for letting me educate people further.
