Bill,
My question is do steroids have any effect on the penis, does it shrink or grow or is there ant effects on the penis that doesn’t have to do with the testes.

I’ve been told by a doctor that it is medically impossible for shrinkage to result from steroid use, but I am not sure that is true. A friend (who goes by the name Juice Lee, believe it or not) insists that he did actually did lose half an inch. He says that luckily he had enough to easily spare that, but would still rather have it back.
I suspect that this is a phenomenon similar to what is seen when one voluntarily contracts the PCG muscle: the penis shortens.
It is not I think that the penis itself really gets shorter, but that it can be pulled in by this muscle. Thus the effect might be reversible with stretching. JL will get on that right away and we’ll report the results.
