Is Gynecomastia hereditary, and can it be prevented?

Answer 1

Somewhat hereditary. But it's more likely to be caused by factors other than inheritance.

These factors, very broadly, will include your age (guys often get a brief episode in their early teens; later in life, declining hormonal function can cause recurrence), whether your testicles and overall hormone system are in good health and in the correct balance, and what external factors are involved, such as taking other substances (not just steroids; some soft drugs and even alcohol can make the condition worse in some patients).

The existence of other medical conditions, e.g. Klinefelter's Syndrome, can predispose some individuals to gynecomastia. Some HIV therapies lead to the condition, but these cases can largely be controlled with anti-estrogen supplements.

'Prevention' for regular guys would mean, I think, having yourself screened regularly by medical professionals, especially if there's a family history of the condition. Early detection is helpful - at very early stages, it is possible that estrogen binders like Clomid can alleviate some symptoms while the underlying cause is treated. If left untreated, it can develop over time into a form known as fibrous (or 'glandular') gynecomastia, which more or less mandates invasive chest surgery to remove it fully.

'Prevention' for those who take anabolic steroids is complex. Very complex. There are many recommendations out there, and the best one of all is still: don't take anabolic steroids. Many herbal, natural, and just plain ol' hogwash remedies have arisen in this field, some with very little compelling evidence that they work.

Keeping your weight healthy for your age and height is a good idea too. Excess fat can complicate the condition, and often removal surgery combines liposuction and tissue excision.

Answer 2

There are several potential causes:
puberty
steroid abuse
obesity
marijuana use (this is in question)
tumors
genetic disorders
chronic liver disease
side effects of many medications
castration
Klinefelter Syndrome
Gilbert's Syndrome
aging
(probably some hereditary cause too)

The best way to prevent the progression of the disease is to detect it early. For that to happen, men have to take matters in their own hands -- literally -- just as women do. Because there is less tissue present, self-examination is easier for men. Simply rub the chest area with your hand and feel for any changes in the breast. Shortly it can be prevented or delayed with early diagnosis and treatment ...
