FSH
Also written as: FSH — follicle-stimulating hormone
Follicle-stimulating hormone, a key fertility hormone measured in reproductive assessments and used in ovarian stimulation protocols.
Full Definition
Follicle-stimulating hormone (FSH) is a gonadotropin hormone produced by the anterior pituitary gland that plays a crucial role in reproductive function. In women, FSH stimulates the growth and maturation of ovarian follicles during the menstrual cycle. Elevated FSH levels typically indicate diminished ovarian reserve or approaching menopause, while FSH levels are routinely monitored during fertility treatments to assess ovarian response and adjust medication dosing. FSH is also administered as a fertility medication to stimulate multiple follicle development in assisted reproductive technology cycles.
Usage
Usage note: Always capitalize when used as abbreviation; lowercase when spelled out except at sentence beginning.
