Male Baldness Info

I heard that one side effect of taking Propecia for male pattern baldness could be impotence or loss of sexual desire and I didn’t think anything of it… I started taking the drug and within one week noticed a drop in my sex drive and a few other changes down below (in size) but ignored it. Anyway, 2 weeks later and i’m still kind of un-interested and had to force myself the other day as I was so worried. Is this all in my head? Is there anybody else out there who has taken Propecia and experienced loss of libido/impotence/lack of sexual desire? I’ve done loads of reading on the net and it seems that this is a BIG problem for lots of men, and some of them…. the side effects have been irreversable. I’d rather stop taking these now if thats the case. Any advice Much appreciated

I once read an article which said that most men lose their hair as a result of increased testosterone levels in their body. Since testosterone increases the sex drive, it was said that the two factors are related. Is this always the case? What about for those men whose hair loss is genetic? Is the increase in libido significant? Does it decrease with time? Since increased testosterone also makes people more aggressive, does that mean that bold men are more aggressive than their counterparts?
