Either women or men have little control over the size of their chest. Ideally, a man’s chest is rock hard muscle or hard from the rib confine. However around 30 percent of men, as indicated by a study in the Indian Journal of Endocrinology and Metabolism, will in general grow a pair of “man boobs” at some age in their lives.
The technical term used is gynecomastia, which is a hormone expert Rob Kominiarek, D.O., medicinal chief of ReNue Health in Springboro, Ohio, says, development of full chest on a man, from the suitable swelling of breast tissues typically caused by an irregularity in hormones. When hormones are in their normal transition, men frequently start developing breasts. This happens mostly during puberty or mature age (since the likelihood for gynecomastia starts going up around 50). However, otherwise as well, “man boobs” can develop at any age.
