Etymology: Gonadotrophins are hormones that act on the gonads, the sex glands that produce eggs and sperm, and the word is a modern scientific construction assembled from Greek parts. Its core is "gonad", coined in New Latin from the Greek "gonē", meaning "generation" or "seed", with the suffix "-ad" added. The second element, "trophic", comes from the Greek "trophē", "nourishment" or "feeding", and so the compound reads roughly as "feeding the reproductive glands." The Greek root "tréphō", "to nourish," gives the same sense. The word was built in stages. "Gonadotrophic" was formed first, describing a substance that nourishes or stimulates the gonads, and "-in", a suffix used in chemistry for substances, was then attached to produce "gonadotrophin". The suffix passed through Latin and Old French into English before being used in this biochemical sense, which is why the final form looks so unlike its Greek ancestors. The result is a technical coinage that the ancient Greeks never used.
