Does the steroid windstraw, which I think is appropriately named/spelled Winstrol, cause sterilization in men?

I just found out I was pregnant. My babys father wants a paternity test because he is on the steriod he calls windstraw (Winstrol). And states he cannot reproduce for 6 months after taking it. As that is the side effect in livestock. I can't find any information regarding this on the internet. Im hoping someone can help me!

You're right. The effect of winstrol to fertility has been studied only on animals so far. Best bet is to get a paternity or DNA test later.
