There are many potential causes on the development of man boobs. This article will present you with some of the most common. Truth be told, almost 25% of Gynecomastia cases – medical term for abnormally large male breasts – is mostly undetermined. But there are factors that are directly linked to their occurrence, which include the following:

  • Increased levels of estrogen – Estrogen is a hormone that is very abundant in a female's body. Though men also produce estrogen, it is in lower levels as compared to women. When estrogen production in a male's body is increased abnormally, the end result can be enlarged male breasts. The surge in estrogen levels can be attributed to different reasons such as testicular tumor or hyperthyroidism. Puberty is perhaps the closest link to the surge of estrogen hormones as the said conditions are quite rare.
  • Decreased testosterone production – This is yet another probable culprit for the development of gynecomastia. An extreme decline in testosterone production can be caused by testicular failure or a genetic disorder, such as Klinefelter Syndrome. Diseases associated with the pituitary gland and hypothalamus may also cause this. Obesity and abuse of anabolic steroids are said to cause the same effect.
  • Medications – About 10% - 20% of gynecomastia cases are linked to medication side effects, especially if the afflicted individual is a post-adolescent. The intake of performance-enhancing drugs, particularly Andostenedione, can cause abnormal breast growth due to increased estrogen activity in the body. Antiandrogens and GnRH analogs – prostate cancer treatment medications – are said to also trigger the development of gynecomastia.
It is important that you know the underlying cause of the condition before you find ways to lose man boobs permanently. One thing that you should bear in mind is to never self-diagnose unless you are a medical doctor. In spite the fact that there is already loads of information on how to get rid of man boobs available in the internet, seeing a doctor is still the best way to diagnose the condition.

If you really want to get rid of man boobs, you will have to undergo a comprehensive physician examination as well as a series of diagnostic tests to ascertain what really caused you to develop man boobs.
