androgenetic alopecia
"I was on 1mg about a year ago on and off for about 6 months. I only had slight pain and discomfort in my lower abdomen/testicles for the first few days. Then my morning wood disappeared and sometimes came back. At about the 6th month i noticed bad shrinkage/ed/low ejaculate volume. 

I stopped taking it and after 1 month of seeing no improvement, I was breaking down. 

I was a tall athletic 30 yr old man and feeling like i had nothing between my legs. Its almost a year since I stopped. I'm about 90% back to my old self (I think I'm one of the "lucky" guys). I thought the  number of negative comments were b.s. (they're not). The percentage of men being damaged must be much higher than reported. Don't take the risk."
