Detailed explanation-1: -Menstruation is one part of a woman’s cycle when the lining of the uterus (endometrium) is shed. This occurs throughout a woman’s reproductive life. With each monthly cycle, the endometrium prepares itself to nourish a fetus.

Detailed explanation-3: -The purpose of the menstrual cycle is to prepare the body for a possible pregnancy. During the menstrual cycle, a mature egg is produced by the ovaries and the lining of the uterus thickens to support a possible pregnancy.

Detailed explanation-4: -The Luteal Phase This phase involves the preparation of the uterine lining, called the endometrium, for potential embryo implantation. A large spike in progesterone levels, another hormone produced by the ovaries, stimulates uterine lining growth to create a friendly environment for a developing embryo.

Detailed explanation-5: -As the egg travels through the fallopian tube, the level of progesterone rises, which helps prepare the uterine lining for pregnancy. If you don’t become pregnant that cycle, the egg disintegrates and gets reabsorbed by your body so menstruation can begin.
