Hello, I am 20 and suffer a bit from MPB. I went to my dermatologist and expressed concern over my receding hair line. To start he put me on Rogaine (5%) and told me to see how that treatment does over the next year. After taking it for a few months, I noticed some growth but mainly just small hairs. Now my question, I researched a good bit about propecia and the side effects. Some I heard were just a bit of impotence while others are so drastic as it makes users sterile. For the people that have used finastride for years (5-10+), what are your results for fertility and other side effects? Does it make you sterile or any thing else? Mind you, I am 20 and having kids is still a big thing on my list of things to do.
