Question

Discuss the role of two ovarian hormones in the process of parturition in humans.

Answer 1

The role of two ovarian hormones in human childbirth (parturition) is as follows:

1. Estrogen: It helps start childbirth by preparing the uterus for contractions, increasing its response to oxytocin, and softening the cervix with the help of prostaglandins.
2. Oxytocin: It is important for childbirth as it causes strong uterine contractions that help in the delivery of the baby. It also helps in the release of milk after birth.
3. Relaxin: It prepares the body for delivery by softening the cervix and loosening the pelvic ligaments, making it easier for the baby to pass through the birth canal.
