androgenetic alopecia
"29 now, started losing my mane since 22 and now have lost most of my crown area with receding frontal hairline. Upon doctor recommendation and Going by the positive effects regarding hair growth which I have read and heard I took the chance and started taking 1mg finasteride back in 1st April 2017; just been 10 days to be exact and started noticing lack of sex drive, poor erection from 2nd day onwards. This has to be the most anti erection drug a man can have.. I would suggest everyone to NEVER ever opt for this if you value your masculine traits.
I am going to stop it now and will never take the same again ever. Already scheduled for a  Follicular Unit Transplant (FUT) HT next week. 
Hence, either opt for minoxidil only treatment or transplant but refrain from this."
