Clinical significance: |
Inhibin-B is the major circulating inhibin in males and can be used as endocrine marker of spermatogenesis in subfertile men. In the female, since Inhibin-B decreases to undetectable levels after normal menopause, certain ovarian cancers (mucinous carcinomas, granulosa cell tumors) continue to produce inhibin after menopause, Inhibin-B can serve as a regular screening test in the female, especially in post-menopausal women. | |
