HCG (human chorionic gonadotropin) is a hormone produced by the placenta during pregnancy, but it does not aid in the expulsion of the infant during labor. Contractions during labor are primarily initiated and intensified by oxytocin, which is produced by both the mother and fetus, and the number of hormone receptors on uterine cells increases in response to these contractions.
