I don't know what he meant. However, sterility and infertility are synonymous. I don't believe that permanent sterility or infertility was ever the issue. But the fact is that when you use steroids, your sperm count drops significantly. This is a form of sterilization. So in answer to his post "steroids don't make you sterile", well that just simply is not the case. Personally, I think it being legal as a form of birth control would be the best thing that could happen.
This was on MSNBC a while back from an article "Male Birth Control Soon a Reality":
"Dr. Andrea Coviello, who is helping to test several male contraceptives at the Population Center for Research in Reproduction at the University of Washington in Seattle.
Coviello and her colleagues have found that a male contraceptive that releases testosterone over three months is potentially a safe and practical method of contraception. The Seattle researchers have been testing a sustained-released, testosterone micro-capsule, which consists of a thick liquid administered by injection under the skin.
“I never had any real noticeable side effects. I didn’t notice any mood changes. I may have put on a little weight,” says Larry Setlow, a 39-year-old computer programmer with a small software company in Seattle. He has taken part in three male hormonal contraceptive clinical trials at the University of Washington and has received both pills and injections.
“They all worked really well and I was able to look at my lab results and see my sperm count drop to zero,” says Setlow."
