2.3 Menstrual cycle (Ovarian cycle): Menstrual cycle is the characteristic feature of primates including human. It involves a series of cyclic changes in the ovary and the female reproductive tract, mainly in the uterus. These changes take place under the effect of gonadotropins and the ovarian hormones respectively. The cycles are repeated with a periodicity of approximately 28 days. The middle of each cycle is characterised by the release of an egg. This egg in every cycle comes alternately from one of the two ovaries. The cycle is divided into four phases.
