Finasteride, known for treating hair loss and enlarged prostate, may also lower cholesterol and reduce heart disease risk. Research by Dr. Jaume Amengual and team, based on a national survey and mouse experiments, suggests finasteride's potential to lower cholesterol and reduce inflammation. The drug's effects on hormones like DHT, linked to heart disease, open possibilities for its use in heart health, including for transgender individuals undergoing hormone therapy. However, potential side effects like sexual dysfunction and psychological issues must be considered.
