Trophic hormone is a hormone that has a growth effect, hyperplasia or hypertrophy, on the tissue it is stimulating.[1] The term trophic is from Ancient Greek τροφικός (trophikós) meaning "pertaining to food or nourishment", here used to mean "growth"; this is the same origin as atrophy. This should not be confused with tropic, as in the similar-sounding tropic hormone – the words and concepts are both unrelated.[2]

A key example of this is thyroid-stimulating hormone stimulating the thyroid; excess thyroid-stimulating hormone can create a goitre.

Trophic hormones from the anterior pituitary include:

Gastrin is a trophic hormone that causes hyperplasia of enterochromaffin cells which may transform into carcinoid tumors.
