Why do men have big nipples?

Male nipples are usually small, and men who like to exercise will have more developed chest muscles. But what causes male nipples to be large? In fact, male breasts are also a sexual characteristic. If the nipples become larger, you should be alert to diseases in the testicular area. For example, poor function and development will lead to breast development, which will make the nipples larger. In addition, liver diseases can also cause changes in the breasts.

Why do men have big breasts?

2.1. Testicular diseases

Poor testicular function, congenital testicular dysplasia, orchitis, testicular damage, testicular tumors, etc., reduce the secretion of male hormones and increase the level of estrogen, leading to breast development.

2.2 Liver disease

All sex hormones in the body are processed by the liver, and estrogen is no exception. If the liver suffers from diseases such as hepatitis, cirrhosis, and liver cancer, the unprocessed estrogen in the body will gradually increase, eventually leading to breast development.

2.3 Adrenal gland diseases

The adrenal glands are an important "source" of estrogen in men. If a tumor grows in the adrenal glands or the tissue proliferates, the estrogen production will increase abnormally, leading to breast development.

2.4. Hypothalamic-pituitary diseases

The hypothalamus-pituitary gland secretes adrenocorticotropic hormone to instruct the adrenal glands to work. Once the pituitary gland suffers from tumors or other diseases, the secretion of this substance will be abnormal, blindly prompting the adrenal glands to produce more estrogen.

2.5. Effects of drugs

Some drugs such as progesterone, isoniazid, reserpine, tricyclic antidepressants, chlorpromazine, methyldopa, spironolactone, amphetamine, digitalis, etc. can also affect the metabolism of estrogen and induce breast enlargement.

The dangers of having large breasts in men

1. High carcinogenicity rate: Surveys have found that the incidence of breast cancer in men with enlarged breasts is much higher than that in women. At the same time, enlarged breasts in men are also prone to breast diseases such as breast hyperplasia and breast cysts, which seriously endanger health.

2. Severe damage to liver function: Men with enlarged breasts will have abnormal liver function, especially high transaminase, which should be taken seriously.

3. Breast skin inversion: Nipple inversion, occasionally accompanied by nipple bleeding. Although the pain is sometimes not very obvious, it is still one of the hazards of male breast development. If the nipple is found to be retracted and the skin is involved, you should be vigilant.

4. Prone to male diseases: Some male patients with breast hypertrophy will also secrete milk. If not treated in time, it will lead to adrenal inflammation and malignant tumors (such as testicular tumors and villous gland epithelial carcinoma).

5. Decreased quality of life of couples: On the one hand, due to the excessive secretion of estrogen by the patient, the male sexual desire decreases; on the other hand, due to psychological factors, the patient will feel inferior and ashamed, thinking that he is "not manly enough", which makes the sex life between the couple no longer harmonious and affects family happiness.
