List of human hormones


Hormones are signaling molecules produced by specialized cells in various human tissues and organs. They regulate diverse physiological processes by binding to specific receptors. Human hormones are commonly grouped into four major structural classes:
Spelling conventions vary between regions. For example, current North American and international usage favors estrogen and gonadotropin, whereas British usage retains the Greek digraph in oestrogen and prefers the earlier spelling gonadotrophin.
The following is a list of hormones found in Homo sapiens organized by structural classes.
