Definition
Gonadotrophin is an alternative spelling of gonadotropin, referring to a group of hormones that stimulate the gonads. These hormones play a key role in sexual development and reproductive function. They include follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Think of gonadotrophins as the body's reproductive system conductors. They ensure that the gonads function properly. These are produced by the pituitary gland, and regulate the production of sex hormones like estrogen and testosterone.
