(Wikipedia) The first phase, also known as menstrual period, the menstrual period begins on the first day of menstruation and lasts 5 days. At this stage, the uterus drops the inner layer of blood vessels and soft tissues, allowing the body to pass through the vagina as blood / menstrual fluid, resulting in a decrease in estrogen and progesterone. (Menstrupedia) At the level of estrogen and progesterone reduction and FSH and LH levels, the primordial follicles grow and mature and allow them to enter the primary follicle.
When menstruation (menstruation) occurs periodically, this is called the menstrual cycle. Regular menstrual cycle is a sign of normal work in an important part of the body.

In the middle of a woman's cycle, on the 14th day, one of her two ovaries will lay eggs. This is called ovulation. After ovulation, the ruptured follicles which released the eggs are converted to corpus luteum and begin to produce progesterone and a small amount of testosterone.
