Undertaking male chest reduction without having an operation or taking medical pills, involves uncovering the triggers that lead to your gynecomastia in the first place, then eradicating them from your system permanently.
Regardless of whether a medical disease is at fault, gynecomastia is usually the result of elevated female sex hormones, namely estrogen. This can result from either medical conditions or environmental triggers that increase estrogen in your body or decrease testosterone.
The reason males (usually) have different appearances than females, is due to the roles that both estrogen and testosterone play in the body. Testosterone is responsible for giving men their extra body hair and muscle during puberty, whereas estrogen gives women their breasts. Gynecomastia occurs when the balance of these sex hormones is altered either naturally or artificially (through steroid abuse).
