Can Finasteride Affect Testosterone Levels?

Finasteride works by inhibiting the conversion of testosterone into DHT, a hormone linked to hair loss. While it doesn’t significantly lower overall testosterone levels, it can alter the balance of hormones in your body. For most men, this doesn’t cause issues, but in some cases, it can lead to side effects like decreased libido or erectile dysfunction. If you’re concerned about how finasteride might affect your hormones, talk to your doctor.
