What is FSH

Follicle-stimulating hormone, also known as FSH, is a hormone checked routinely between days 2-4 of the menstrual cycle. It is produced by the pituitary gland to stimulate the ovaries to develop follicles. As a dominant follicle develops, it in turn sends certain signals (inhibin-B) that will suppress FSH release (negative feedback).
