follicle-stimulating hormone
Pronunciation: FOL-ih-kul STIM-yuh-lay-ting HOR-mohn
A gonadotropin hormone that stimulates ovarian follicle development. Essential for monitoring fertility treatments.
Full Definition
Follicle-stimulating hormone (FSH) is a 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 follicular phase of the menstrual cycle. FSH levels are commonly measured in fertility assessments as they can indicate ovarian reserve and function. Elevated FSH levels may suggest diminished ovarian reserve, while abnormally low levels might indicate pituitary dysfunction. In assisted reproductive technology, synthetic FSH preparations are frequently used to stimulate multiple follicle development.
Usage
Usage note: Commonly abbreviated as FSH; ensure consistency in hyphenation when spelling out the full term.
