“The researchers followed 3,040 men ranging in age from 45 to 78, all of whom suffered from prostate enlargement—another condition finasteride [Propecia] is approved to treat. In the study’s first year, 15 percent of the men on finasteride suffered new sexual side effects, compared with only 7 percent of the men on placebos.”
Male pattern baldness results from hair follicles shutting down. This process is controlled by a hormone called dihydrotestosterone (DHT), which is related to testosterone. Finasteride is the generic form of Propecia, which is a medication to treat male pattern hair loss. This medication however, has some sexual side-effects which includes a decrease in sexual drive and erectile dysfunction. Most of the men in the study were able to tolerate the sexual side effects, but caused others (4% of the men in the study) to drop out of the study. Even though there are studies that state that the sexual side effects of the drugs are rare and reversible, other studies have been found that make Propecia look very suspicious. With such controversial medications it is important to look at both sides of the argument to be able to make an informed decision since it wouldn’t only affect your physical health, but also your sexual and emotional/mental health as well as your intimate relationships.
