What hormone can be used to induce abortion?

Oxytocin is a hormone known primarily for its role in childbirth and lactation, but it also has implications in inducing contractions of the uterus, which can facilitate the process of abortion when used correctly in a clinical setting. Administering oxytocin can stimulate the uterus and help expel its contents, making it relevant in contexts where abortion is a medical procedure.

While estrogen and testosterone are key hormones in reproductive health, they do not have a direct role in inducing abortion. Progesterone is essential in maintaining pregnancies and counteracting uterine contractions, which would make it contrary to the goal of inducing an abortion. Thus, oxytocin is specifically recognized for its practical application in this context.
