Webb15 maj 2024 · Inhibin B is mainly secreted by the smaller, non-selected cohort follicles, whereas Inhibin A is mainly produced by the dominant follicle and in a natural cycle, Inhibin A levels start to rise in the late follicular phase with the presence of larger size follicles of a size of ~15 mm (11, 39). WebbSerum inhibin A and B levels fluctuate during the menstrual cycle. At menopause, with the depletion of ovarian follicles, serum inhibin A and B decrease to very low or undetectable levels.

WebbTwo molecular forms inhibin A and inhibin B is found and have two subunits α and β joined together by a disulfide bond. Inhibin also inhibits the action of the activin by replacing the activin from the activin receptor site. However, the activity of the inhibin is aided by beta glycan that acts as a coreceptor in the complex. WebbSerum inhibin A and B levels fluctuate during the menstrual cycle.

WebbWhereas inhibin (primarily inhibin B) production typically ends following the LH surge in many species, the primate corpus luteum synthesizes and secretes significant amounts of inhibin A. Investigators report immunostaining for inhibin subunits primarily in granulosa luteal but not paraluteal cells; these cells likely produce other members of the inhibin …
