Finasteride is the active ingredient found in both Propecia and Proscar, prescription drugs intended to treat male pattern baldness and benign prostatic hyperplasia (BPH). However, recent research shows a strong link between Finasteride and sexual side effects such as erectile dysfunction, decreased libido, and testicular pain.
Finasteride Sexual Side Effects Research
In early 2011, a study conducted at the Center for Andrology and Division of Endocrinology at George Washington University confirmed that medications containing Finasteride, such as Proscar and Propecia, can cause sexual side effects.
This study involved 71 men between the ages of 21 and 46 who reported sexual side effects after using Finasteride. Results of the study showed that patients developed the following:
- Low libido: 94 percent.
- Erectile dysfunction: 92 percent.
- Decreased arousal: 92 percent.
- Problems with orgasm: 69 percent.
Other Finasteride side effects include:
- Decrease in semen volume
- Ejaculation disorders
- Male breast cancer
- Prostate cancer
- Testicular pain
- Genital shrinkage
- Penile fibrosis (Payronie’s Disease)
- Endocrine system failure
- Body disfigurement
Finasteride Erectile Dysfunction Lawsuit
On April 12, 2012, the FDA issued a press release announcing that Proscar and Propecia warning labels will be updated to include information regarding the risk of persistent sexual side effects. The new warning labels contain information about orgasm, libido, ejaculation, and erectile dysfunction disorders that may persist even after patients stop using the drug.
