Estradiol, also known as Estradiol and Estradiol. It is a unique female hormone. When girls reach the age of 10 to 11, their nipples become elevated and slightly painful, and a hard lump as large as a silkworm’s head appears at the base of the nipple, which then increases in size and becomes a towering bun-like breast. However, in men, excessive estradiol can lead to feminization of the male gender, a loss of male secondary sexual characteristics, an increase in breast size, and a thinning of the female voice. Many parents are very much against their children undergoing surgery for fear of irreversible sequelae. We need to look at gynecomastia surgery in a scientific and rational way. First of all, we need to understand the male breast itself. Both men and women are born with breast tissue as part of their body structure. However, during the process of growth, the hormonal imbalance in the body leads to abnormal development of mammary gland hyperplasia, resulting in a feminine breast appearance. Since the growth is abnormal, surgical removal of the enlarged gland will prevent the possibility of more serious lesions in the future. The procedure is minimally invasive and uses superficial liposuction to restore the aesthetics and flatness of the male chest without touching other tissues or organs of the body, so there are no after-effects. In layman’s terms, the removal of tissue that should not be there can only be beneficial.
