Inhibin is secreted before ovulation

WebbInhibin is a dimeric 32-kD glycoprotein hormone that participates in the regulation of the pituitary-gonadal feedback system. 337-340 Inhibins secreted in the ovary consist of … FSH stimulates the secretion of inhibin from the granulosa cells of the ovarian follicles in the ovaries. In turn, inhibin suppresses FSH. Inhibin B reaches a peak in the early- to mid- follicular phase, and a second peak at ovulation. Inhibin A reaches its peak in the mid- luteal phase. Visa mer Activin and inhibin are two closely related protein complexes that have almost directly opposite biological effects. Identified in 1986, activin enhances FSH biosynthesis and secretion, and participates in the regulation of the Visa mer The activin and inhibin protein complexes are both dimeric in structure, and, in each complex, the two monomers are linked to one another by a single disulfide bond. In addition, both complexes are derived from the same family of related genes and proteins but differ in … Visa mer Activin Activin A is more plentiful in the adipose tissue of obese, compared to lean persons.
