Rhythmic reproductive cycle in female primates (Monkeys, apes, humans etc.) is called menstrual cycle. The first menstrual cycle (Menarche) that begins at puberty. It is repeated after an average interval of 28/29 days. Release of one ovum takes place in the middle of each menstrual cycle. The menstrual cycle ceases around post 50 years of age in humans and that stage is called Menopause. Proper understanding of the Menstrual cycle can be used to apply periodic abstinence which is a method of natural birth control. A couple can stay away from performing coitus/ sexual intercourse between the `10^(th)` and `17^(th)` of the menstrual cycle. These are the days when ovulation takes place, resulting in higher chances of fertilisation. This can help with a natural course of family planning.
