A hormone that stimulates the growth and function of the gonads (reproductive glands); the British spelling variant of gonadotropin.
From gonad (from Greek gonos 'seed') + trophin (from Greek trophē 'nourishment'). The term emerged in early 20th century medical science when scientists discovered hormones that 'nourish' or stimulate reproductive organs.
The pituitary gland in your brain releases gonadotrophin to tell your body when and how to develop during puberty—it's literally your body's chemical messenger controlling one of life's biggest transformations!
