I am 16 and i am having puffy nipples for the last couple of years. people say the are due to gynecomastia. these puffy nipples are really killing my confidence. how will the go away?

Endocrinologist time: Gynecomastia is breast tissue enlargement in men, and is due to the effects of estrogen hormones. A little male breast enlargement can be normal, especially in teens and even college students. A lot of breast enlargement would be a problem needing examination. Medications that block the production or effects of estrogen can reverse some gynecomastia. An endocrinologist is the specialist to visit.
