Men taking finasteride, a drug used to prevent prostate cancer, need not worry about sexual dysfunction side effects, according to a study from the Southwest Oncology Group. Physicians usually warn patients that sexual dysfunction is a possible side effect when discussing finasteride.
This study came out of the Prostate Cancer Prevention Trial, a large National Cancer Institute-funded study which found that finasteride is effective at preventing prostate cancer in men age 55 and older. This trial showed that finasteride could reduce a man's risk of prostate cancer by almost 25 percent.
