Quizplus · Accepted Answer

Relaxin, secreted by the corpus luteum and placenta, increases flexibility in the pubic symphysis and other pelvic ligaments during late pregnancy, which facilitates the passage of the fetal head during childbirth. Estrogen also plays a role in this process, but it primarily stimulates the growth and development of the reproductive tract during puberty and the menstrual cycle. Inhibin and testosterone are hormones produced by the ovaries, but they do not have a significant effect on childbirth preparation. Prolactin is a hormone produced by the anterior pituitary gland that stimulates milk production in the mammary glands after childbirth.
