Summary Introduction
To determine: -The benefit of consumption of placenta by many female mammals after giving birth.
Introduction: In mammals, the fetus develops within the body of the mother and the developing fetus extracts all the nutrients from the mother for its growth. The placenta is an organ formed during pregnancy and this organ acts as the connecting link between the bodies of the mother and the fetus. The blood flowing in the placenta carries the oxygen and nutrients for the fetus.

- Animals attract mates through a variety of behaviors. Diurnal animals tend to rely on visual cues, while nocturnal ones make frequent use of pheromones. In recent years, environmental pollutants called endocrine disruptors are on the rise.
