Main Page | See live article | Alphabetical index Follicle stimulating hormone (FSH) is a hormone produced by the pituitary gland that activates ovulation in women. The release of FSH causes the immature follicles to grow in the ovaries. As the follicle grows, it releases inhibin which shuts off the FSH production. This article is a stub.
