绒促性素（HCG）自将康孕妇尿中提取、精制而成的一种天然促性腺激素，具有类似黄体生成素的功能。对女性可促进卵泡的成熟及排卵，并维持黄体的功能。对男性，能剌激睾丸间质细胞的发育，增加雄激素分泌，促使睾丸下降和男性第二性征发育。与尿促性素合用，可模拟生理性的促黄体生成素高峰，而促发排卵。临床上绒促性素至今仍是治疗月经失调、无排卵性不孕症、先兆流产和习惯性活产、隐睾症、男性性功能低下等的首选药物。此外，它还广泛应用于性保健，计划生育事业以及渔业和畜牧业的生产。

HCG is a natural gonadotropin extracted and refined from the urine of healthy pregnant women, which has a function similar to luteinizing hormone. For women, the maturation and ovulation of follicles can be promoted, and the function of the yellow body is maintained. For men, it stimulates the development of interstitial cells in the testes, increases androgen secretion, and promotes testicular decline and the development of second sexual characteristics in men. In combination with menotrophin, it can simulate the peak of bio-rational provonomic serotoin and promote ovulation. Clinical chorionic gonadotrophin is still the preferred drug for the treatment of menstrual disorders, no ovulation infertility, pre-eclampsia and habitual live births, cryptotestism, and low male sexual function. In addition, it is widely used in sexual health care, family planning and fisheries and livestock production.
