Your best chance of conceiving a child is on a very high dose cycle. Once test goes over the gram mark, spermatogenesis is once again triggered. The steroli cells in the balls have to bath in testosterone to produce fertile sperm and that is only capable at very high doses, when one takes 500mg test for example the amount that passes through the testicles is not enough.
Actually don't have kids you are doing society a greater deal.
