Hormones are involved in Parturition:
In Parturition, hormones play a major role. Several hormones are involved in Parturition:
1. Oxytocin:
It secretes from the fetus and mother’s posterior pituitary. It stimulates the uterus to contract. It also causes powerful contractions of myometrium during parturition.
2. Prostaglandin:
It stimulates more contractions of the uterus.
3. Relaxin:
It causes the aidening of the pelvis by relaxing the pubic symphysis of the pelvic girdles.
4. Oestrogen:
This hormone secretes from the ovaries and induces oxytocin receptors in the uterus.
