Nursing a newborn can cause uterine cramping. Which hormone is responsible?

Question

Quizplus · Accepted Answer

Oxytocin is responsible for causing uterine cramping during nursing due to its ability to contract smooth muscles, including those in the uterus. This helps to promote the return of the uterus to its pre-pregnancy size and prevent postpartum hemorrhage. Estrogen and progesterone levels decrease after delivery, which actually helps to stimulate milk production. Prolactin is responsible for milk production, while FSH (follicle-stimulating hormone) is involved in the menstrual cycle and reproductive system.
