Most men's breasts spontaneously disappear in time for college. But they can start up again. Breast growth can occur with declining testosterone levels in aging men. And many drugs cause breast growth: hormones for prostate cancer, prescription drugs such as spironolactone and Propecia (finasteride), the antifungal ketoconazole, digoxin, lovastatin, verapamil, cimetidine, respirodone, methyldopa, melatonin, and the acquired immunodeficiency syndrome (AIDS) drug efavirenz. Marijuana and anabolic steroids are notorious for causing breast growth; half of steroid users develop gynecomastia. Thyroid disease, liver disease, alcoholism, AIDS, and kidney failure are associated with male breast growth. Overall, a third of adult men have some degree of breast growth.
