Inhibin B is a glycoprotein produced in the ovary (by follicular granulosa cells) that inhibits FSH secretion in the pituitary gland. Thus, if inhibin B levels are low, FSH hormone levels will increase.
Because ovarian reserve and inhibin B decrease with female age, inhibin B values below 35-45 pg/ml may be indicative of low ovarian reserve.
