In females some studies have suggested that inhibin may also be produced by the placenta. In females inhibin inhibits FSH secretion. It does however not have any effect on the secretion of LH. When inhibin is secreted, a relatively higher concentration of LH is secreted from the anterior pituitary gland than FSH. Therefore during follicle development, the increased LH concentration causes cessation of the recruitment of further follicles under the effect of FSH. The hormonal changes resulting from the production of inhibin cause some of the previously recruited follicles to undergo atresia.

<br />Inhibin in the female can also be diminished by GnRH and enhanced by insulin-like growth factor-1 (IGF-1).
