Webb21 jan. 2024 · Inhibin A and inhibin B are hormones associated with reproduction and the development of oocytes (immature egg cells) in women’s ovaries. In women, these hormones are made mostly by the ovaries and by the placenta during pregnancy. Additionally, inhibin A and/or B may be produced by certain types of ovarian tumors. WebbThey are responsible for the differentiation of spermatids, the maintenance of the blood-testis barrier, and the secretion of inhibin, androgen-binding protein and Mullerian-inhibiting factor.

WebbInhibin A also appears to be a suitable marker for epithelial tumors of the mucinous type with about 20% of cases having elevated inhibin A levels. In contrast, inhibin is not a … WebbInhibin is secreted mostly by granulosa cells and has a role in regulating the pituitary secretion of FSH. Therefore, inhibin is a potential marker for ovarian function and follicular content. The main function of inhibin in women is regulation of pituitary FSH secretion.
Webb1 apr. 1997 · INHIBIN IS a regulatory peptide that inhibits FSH synthesis and release ( 1 – 3 ). It was discovered in 1932 as a factor that suppressed pituitary gonadotrope hypertrophy after castration and was eventually identified as a heterodimer of an α and one of two β-subunits (βA and βB) ( 1 – 6 ).
WebbElevations of serum inhibin A and B are detected in some patients with granulosa cell tumors. Inhibin A elevations have been reported in approximately 70% of granulosa cell tumors.
