Let’s make this abundantly clear for the steroid user in his 20s or 30s considering starting a family. When you are using steroids, your sperm count is going to be too low for you to make a baby. Can we be any clearer than that? Additionally, the longer you are on steroids without a break, the longer it will take for your sperm count to return to levels adequate for you to produce a child. In other words, if you plan on growing your family, you should be holding off using steroids. "
and this
The testicles need pituitary hormones to be stimulated to make sperm. If these are absent or severely decreased, the testes will not maximally produce sperm. Importantly, men who take androgens (steroids) for body building, either by mouth or injection, shut down the production of hormones for sperm production.
