Increased follicle stimulating hormone (FSH)

Follicle-stimulating hormone (FSH) chemical structure: is a glycoprotein, which consists of two subunit peptide chains a and b combined by covalent bonds. A hormone secreted by basophils in the anterior pituitary gland and composed of glycoproteins. The main role is to promote follicle maturation. Human follicle stimulating hormone promotes the proliferation and differentiation of follicular granulosa cells and promotes the growth of the entire ovary. Acts on the seminiferous tubules of the testis to promote sperm formation. FSH injection only increased the number of follicles and had no effect on follicle maturation. Follicle-stimulating hormone released by the hypothalamus controls the secretion of follicle-stimulating hormone. During the menstrual cycle, the concentration of FSH in the blood and the amount of FSH excreted daily by the urine change with the cycle. After menopause, FSH excretion in blood and urine increases. The FSH value rises rapidly, possibly due to ovarian function decline.
