Adipose tissue is a source of estrogen
The fact is that adipose tissue is capable of converting androgens into estrogens. This reaction takes place in adipose tissue even before puberty, when a small amount of androgens is produced in the adrenal glands in both sexes. The greater the volume of adipose tissue, the more male androgens will be converted to female estrogens. Accordingly, as the amount of adipose tissue grows and increases, girls, as a rule, begin sexual development earlier than boys, which, in itself, further accelerates acceleration. Thus, the increase in caloric intake and the subsequent acceleration accelerate puberty of both sexes, but the ability of adipose tissue to produce estrogen further boosts the development of girls. Therefore, even among heterosexual twins born on the same day, a girl will develop more rapidly, and her younger sister by 1-2 years during prepubertal period can catch up or even overtake her older brother in development.
The importance of the dependence of the timing of puberty on body weight can hardly be overestimated, especially for women. Bearing and feeding requires significant resources from the body, so nature has taken care that the girl first gains the minimum body weight necessary for reproduction. In the wild, this mechanism had a significant adaptive role – the ability to reproduce appeared only in the presence of food resources. It is no coincidence that in modern women, a significant decrease in body weight as a result of anorexia or “drying” in athletes leads to the cessation of menstruation and a decrease in fertility.Поділитися цим:
