That's not true. Androgen stimulates the production of sperm. Androgen is mainly synthesized and secreted by testis, and a small amount can also be secreted by adrenal gland and ovary. The natural androgen is testosterone, which has androgenic activity and protein assimilation. Hormones that promote the maturation of male accessory organs and the appearance of secondary sexual characteristics, and maintain normal sexual desire and reproductive function. Testosterone secreted by testis is the main steroid hormone. Adult male testes secrete about 4~9 mg of testosterone every day, and female ovaries also secrete a small amount of testosterone. Androgen is produced by testis. When boys and children enter adolescence, the testicles begin to secrete androgens to promote the development of reproductive organs, and secondary sexual characteristics appear, resulting in sexual desire and libido. Androgen can also stimulate appetite, promote protein synthesis and reduce urinary nitrogen excretion. Its main function is to stimulate male accessory sexual organs to make them mature, maintain normal sexual desire, promote the development and maturity of sperm, promote the synthesis of protein and the growth of skeletal muscle, and make muscles developed; Inhibit the increase of body fat and stimulate the growth of red blood cells and long bones; Promote the formation of secondary sexual characteristics. The male hormone secretion of middle-aged and elderly people is gradually decreasing, the sexual function is gradually declining, and the metabolic function of each system is also declining. Therefore, the normal secretion of androgens is very important for maintaining men's normal sexual life, maintaining youthful vitality and keeping youth alive. Androgen is actually a general term for a series of hormones, including testosterone, androstenedione and dehydroepiandrosterone, among which testosterone has the largest yield and the strongest effect. Testosterone and FSH jointly promote the development of testicular seminiferous tubules and the occurrence and maturation of sperm. Testosterone is also necessary for the development and maturation of epididymis, vas deferens, seminal vesicle and prostate. Therefore, if the concentration of testosterone is low, the spermatogenic function will decrease obviously. Androgen can be increased and improved by dietary adjustment, such as eating animal viscera, foods containing zinc (oysters), foods containing arginine (eels, loaches), foods containing calcium, foods rich in vitamins and so on.
