Started loosing my hair when I was 20 years old. Started to use Propecia at age 20 till six months ago. I stopped using propecia as my sperm count level had dropped to 1 million from a normal 20 million sperm per milliliter. I am currently still trying to have a baby with my wife and last month after a sperm test my count are back to normal thankfully. 

Alot of my hair has dropped between these 6 months of absent propecia intake. I will eventually start back on Propecia after my wife gets preagnant.
