What is gonadotropin

  Gonadotropins (Gn) are glycoprotein hormones that regulate gonad development in vertebrates and promote the production and secretion of sex hormones. For example, luteinizing hormone (LH) and follicle-stimulating maturation hormone (FSH) secreted by the anterior pituitary gland work cooperatively to stimulate the development of germ cells in the ovary or testis and the production and secretion of sex hormones. Human placenta secretes chorionic gonadotropin (HCG), which promotes progesterone secretion by the corpus luteum during pregnancy. HCG can be present in the urine at the beginning of pregnancy, reaching its peak in the second month of pregnancy, and is often used as a clinical pregnancy indicator.

What is gonadotropin

  Second, the function of

  LH is also known as interstitial cytohormone (ICSH) because it acts on the interstitial cells of the testis and stimulates the production and secretion of androgens. The main effect of LH on the ovaries of female animals is to selectively induce the rapid growth of individual follicles before ovulation. When LH secretion reaches orgasm, it triggers ovulation and converts the follicle wall into corpus luteum and secretes progesterone after ovulation. The important role of FSH is to promote the growth and development of follicles in the ovary and sperm production in the seminiferous tubules of the testis in males.

  Three, the application

  Gonadotropin obtained from animal pituitary gland has been widely used in animal husbandry and aquaculture, but has no effect on human beings. HCG can be prepared from the urine of pregnant women, or the mixed preparation of LH and FSH extracted from the urine of menopausal women, referred to as human menopausal gonadotropin (HMG), which can be used to treat hyposexual dysfunction clinically.
