A member asked:

Please explain to me what causes gynecomasita in puberty?

A doctor has provided 1 answer

Gynecomastia: About half of males will undergo a transient nipple/breast enlargement at he onset of puberty.Males actually make a little estrogen which is very close in structure to testosterone.Normally it will resolve slowly as other hormonal changes kick in over about a year. Carrying around extra weight can aggravate the issue as fat can masquerade as breast tissue.
