Explanation:
Menstruation is the monthly periodic discharge from the vagina of the females caused due to the shedding of the thickened lining of the uterus in absence of pregnancy.
The menstrual cycle is affected due to the rise and fall of hormones. During this cycle after the formation of the ovarian follicles the internal lining of the uterus thickens. Subsequently growth of the egg takes place and the uterus begins to prepare for implantation provided the egg is fertilized by the male sperm. This condition is required for pregnancy.
The egg released from an ovary at around fourteen day in the cycle. The thick lining of the uterus provides necessary nutrients to an embryo after implantation. If fertilization and implantation does not take place, the lining of the uterus breaks down along with the blood vessels and is released through the discharge known as menstruation.
The menstruation is also under the control of hormones such as progesterone and estrogen which falls and causes the corpus luteum to degrade and finally menstruation occurs.
