Answer 2

sounds like a job for....  Google!

Answer 3

yes

but it may become permenant

Answer 4

A couple of things here. First of all, the doses of testosterone effects something that effects the sperm production, and it has to be a high dosage. When he takes in testosterone that's not from his own body then the body slows down its own testosterone production to insure hormonal balance. So his own production slows down but is being replaced by pills or whatever, and so will the sperm production but it doesn't make that big of a difference. So you can still get pregnant but its just not as likely.

Answer 5

In normal men, chronic testosterone (T) administration results in negative feedback suppression of gonadotropin and sperm production. However, azoospermia (no sperm) is achieved in only fifty to seventy percent of men treated with high dosages of T. Furthermore, the relative sensitivity of LH and FSH secretion to chronic administration of more physiological dosages of T is unclear.

1) LH and FSH secretion are equally sensitive to the long term negative feedback effects of T administration; 2) sperm production is suppressed in parallel with the LH and FSH reductions induced by chronic T administration; and 3) even at the clearly supraphysiological dosage of 300 mg/week, T enanthate does not reliably induce azoospermia in normal men. However, there was also no evidence of a stimulatory effect of this T dosage on spermatogenesis. Furthermore, we found no evidence of major adverse health effects of T administered chronically even at the highest dosage.

So...While the sperm count is decreased, it is frequently not zero and testosterone use of this type is not a reliable birth control method.
