Have you ever noticed that no matter what type of exercising you do, your chest area never seems to improve? Does your chest skin always seem to stay slack (too elastic) and suffer from looseness (laxity)? Do your breasts seem full of fatty tissue or abnormally large? Good skin elasticity is desirable since it makes for a smooth surface contour. Tight skin is generally seen in the very young and is gradually lost as we age. Even through middle age, however, we retain some elasticity. If you are not obese, the skin envelope can always shrink and adjust to a reduced profile following a male breast reduction procedure.
Primary hypogonadism (indicating an intrinsic problem with the testes in males) leads to decreased testosterone synthesis and increased conversion of testosterone to estradiol potentially leading to a gynecomastic appearance.  Klinefelter syndrome is a notable example of a disorder that causes hypogonadism, gynecomastia, and has a higher risk of breast cancer in males (20–50 times higher than males without the disorder).  Central hypogonadism (indicating a problem with the brain) leads to decreased production and release of luteinizing hormone (LH) (a stimulatory signal for endogenous steroid hormone synthesis) which leads to decreased production of testosterone and estradiol in the testes.
