• Obstetrician

    Obstetrics is the field of study concentrated on pregnancy, childbirth, and the postpartum period. As a medical specialty, obstetrics is combined with gynecology under the discipline known as obstetrics and gynecology (OB/GYN).

     
  • Ovulation

    Ovulation is the release of egg from the ovaries. This occurs about midway through the menstrual cycle, after the follicular phase. The few days surrounding ovulation (from approximately days 10 to 18 of a 28-day cycle), constitute the most fertile phase.

     
  • Oxytocin

    Oxytocin (Oxt) is a hormone that is released into the bloodstream in response to stretching of the cervix and uterus during labor and with stimulation of the nipples from breastfeeding. As a medication, it is used to cause contraction of the uterus in order to start labor or increase the speed of labor, and to stop bleeding following delivery. For this purpose, it is given either by injection into a muscle or into a vein.
