INHIBIN A

Inhibin A is one of the two forms of Inhibin. Females produce both types of Inhibin, while men only produce and synthesize Inhibin B. Inhibin A is secreted together by main follicles and corpus luteum, and Inhibin B is mainly secreted by small developing follicles. Both the forms of inhibin fluctuate in level during the menstrual cycle. The abnormal levels of both forms of inhibin reflect varied conditions in men and women.
