does steroids cause impotency?

Answer 1

Yes, that's a known side effect. They can also kill you, which is even worse for your sex life. Just don't mess with them.

Answer 2

I'm guessing you're talking about Anabolic Steroids (muscle enhancement) and probably male side effects, in that case, yes they do cause temporary impotency:

Reduced sexual function and temporary infertility



Here's the full side effects article for men:

Male-specific side effects

* Gynecomastia – Breast development in males. It is usually due to high levels of circulating estrogen. These high levels are the result of the increased level of conversion of testosterone to estrogen via the aromatase enzyme.
* Reduced sexual function and temporary infertility[11][12][13]
* Testicular atrophy – Temporary side effect that is due to decreases in natural testosterone levels. The size of the testicles usually return to normal within a few weeks of discontinuing anabolic steroid use


Here's the link for the page on Anabolic Steroids:

And here's the link for Steroids in general if you meant other generals:

Answer 3

No they don't. They will cause the testicles to shrink temporally, due to them not producing testoterone. This is because you are taking them orally or injecting them. Testoterone will actually increase a males sex drive.
