Which of the following hormone controls the uterus?

Progesterone has a dominant role in controlling both the uterus and cervix. It maintains the uterus lining or the thickness of the uterus wall. 

If an egg is fertilized, the corpus luteum doesn’t break down and continues to produce progesterone. This progesterone stimulates blood vessels to supply the endometrium or inner wall of the uterus. It also prompts the endometrium to provide nutrients to the developing embryo. 

Antiprogestins induce early, preterm conditioning leads to preterm labour.
