Yes, Observation: Gynecomastia, enlarged breasts is usually benign; occurs transiently in 40-60% of adolescent males 10-16 yrs old. Usually resolves spontaneously within 3 yrs in 90%. Can be caused by: high Estrogen, low Androgen levels; specific drugs (eg. anabolic steroids, some anti-depressants, alcohol & marijuana use); & more. Less tender & softer nipples can mean resolution. Continue to follow w/ your doctor.
