Emergency childbirth rupture. Bleeding after delivery (postpartum hemorrhage) After delivery of the baby, a uterus that is not contracting (atonic uterus), ruptured uterus, remaining parts of placenta or baby or infected remaining parts of placenta or baby can cause severe bleeding. Postpartum bleeding is usually managed preventatively by massaging the lower abdomen (fundal massage), which increases contraction of the uterus and stops bleeding. Additionally, steady traction is applied to the cord to prevent trauma, cord avulsion (tearing of the umbilical cord), uterine inversion, and retained placental products, all of which can increase blood loss and/or the risk of infection. Postpartum hemorrhage is
Sexual mimicry males to produce offspring of higher fitness. Non-dominant females are observed copulating more often with lower-ranking males. It is costly for female hyenas to give birth through their long peniform clitoris. The umbilical cord is 12–18 cm long, while the journey from the uterus to the clitoris end is 40 cm. The umbilical cord often breaks before the cub emerges, leading to death by anoxia for many young. This journey is not only harmful for the cubs, but also for the mother. The tissue of the clitoris will sometimes rip open when giving birth for the first time which can
