It's definitely possible, but pretty tough. Also I read an article on the quantity and quality of sperm when AAS are used at various levels. At low levels, your production is suppressed, but not totally. At higher levels, your sperm counts are so low that it's next to impossible to conceive. The article did note that in all cases that quantity of sperm were lower and the overall quality of sperm were low too. That means you have a higher likelihood of other issues down the road. It didn't go into what the "other issues" were though. If you friend does't know, have him ask her straight out.
