Detailed explanation-1: -Progesterone has been used to inhibit uterine contraction and prevent abortion and preterm labor.
Detailed explanation-2: -Low levels of oxytocin could stop uterine contractions during the birthing process and prevent milk ejection after giving birth.
Detailed explanation-3: -Acting as a major inhibitory brake in the luteal phase of the ovarian/menstrual cycle, progesterone inhibits gonadotrophin-releasing hormone (GnRH) and luteinising hormone (LH) secretion1.
Detailed explanation-4: -Progesterone plays a vital role in the maintenance of the uterus during pregnancy. As such, an important issue of concern regarding the loss of this steroid hormone correlates with miscarriage and pre-term labor.
Detailed explanation-5: -The follicle becomes the corpus luteum and this produces oestrogen and progesterone which inhibit FSH and LH production by the pituitary.
