WentworthMiller1992, I can vouch for both the medications known as Propecia (Finasteride), and Avodart (Dutasteride). I've been on Finasteride for 2-1/2 years, and Avodart for 2. I've had no side effects whatsoever, or any other bad health problems. What I HAVE had is some good hair success! Since the day I started the hair loss meds, my hair has just got better. After about 6 months on Finasteride, I started Avodart (Dutasteride). I've had amazing success as far as no further loss, and I've had slow but definite regrowth over the 2 year time frame since.
In that time frame, I've never had any problems sexually with my wife. And I'm 41 years old. You are half my age, so you will probably have even less problems with the meds.
I hope you decide to go forward with meds as far as your treatment plan, as it is the best prevention against further loss and helps during a hair transplant also! Good luck!
