Quizplus · Accepted Answer

Progesterone is the hormone responsible for maintaining the pregnancy, and its levels have to drop for labor to start. Once the levels of progesterone decrease, the body can begin to produce prostaglandins, which cause the cervix to soften and thin, leading to the onset of labor. Estrogen, testosterone, relaxin, and inhibin can all play a role in pregnancy or reproductive processes but are not specifically responsible for initiating labor by reducing their effects.
