WebbInhibin is a nonsteroidal hormone that is involved in the follicular phase of the human menstrual cycle (Groome et al., 1996). Inhibin has also been identified as a regulatory hormone in the follicular phase of the equine estrous cycle ( Medan et al. , 2004 ). WebbThe normal range of inhibin in post-menopausal women is < 5 pg ml-1, in pre-menopausal women 2-80 pg ml-1 (2-10 pg ml-1 in the follicular phase, 40-80 pg ml-1 in the luteal phase). This assay was used to determine inhibin levels in sera from 15 (five pre-menopausal and ten post-menopausal) patients with granulosa cell tumours of the ovary.
