It is not true that men with low androgens live longer; this claim has not been medically tested or clinically proven. Androgens are produced by the testes, in addition, the adrenal cortex and ovaries can also secrete small amounts of androgens. After male children enter puberty, the testes begin to secrete androgens to promote the development of reproductive organs, the appearance of secondary sexual characteristics and sexual desire. At the same time, androgens also stimulate appetite, promote protein synthesis, reduce urinary nitrogen excretion and so on. The length of human life is affected by a variety of factors, both congenital and acquired, and there are many studies on life expectancy, such as the telomerase theory, DNA methylation theory, etc. However, there are no authoritative references that indicate that men with low androgen live longer, which requires further exhaustive research.
