Hyperandrogenism in men does not usually lead to chest development, causing large chest performance. Hyperandrogenism in men may affect pubertal development, leading to developmental abnormalities during puberty, such as precocious puberty, affecting height development, leading to shorter adults, and may also affect the male cardiovascular system. However, hyperandrogenism generally does not affect mammary gland development and does not cause symptoms of large breasts. Men with large breasts may consider the cause of high estrogen. If men have excessive estrogen secretion, the breasts are affected by estrogen and stimulate abnormal mammary gland development, which may lead to the abnormal phenomenon of large breasts. When male androgen is too high or chest is too large, it is recommended to go to the hospital in time for examination and follow the doctor’s instructions for treatment.
