What does gonadotrophin mean?
Gonadotrophin is a scientific and medical term for a hormone that stimulates the gonads, the organs that produce reproductive cells: the ovaries in females and the testes in males. The term is used both for individual hormones and for the broader group of gonad-stimulating hormones. Important examples include follicle-stimulating hormone and luteinising hormone, which are produced by the anterior pituitary gland, and human chorionic gonadotrophin, which is produced during pregnancy and is the substance detected by many pregnancy tests. Gonadotrophins are important in fertility assessment and reproductive medicine, and doctors may measure their levels in blood or use them as medicines. The word is chiefly encountered in medical, biological, and veterinary contexts. It is written gonadotrophin in traditional British usage, while gonadotropin is the standard American spelling. Its importance lies in its central role in coordinating reproduction and in providing clinicians with information about ovarian or testicular function.
