Explanation

In human females, the periodic reproductive cycle is completed in approximately 28 days. This is known as the menstrual cycle. The menstrual cycle is divided into three phases.The follicular phase begins with the first day of menstruation and ends with ovulation. During this phase, an egg cell matures in an ovary. The ovulatory phase occurs about 14 days before the next menstrual period begins. During this phase, the egg cell is released from the ovary. The luteal phase begins after ovulation and ends with the start of the next menstrual period. During this phase, the egg cell travels down the fallopian tube and may be fertilized by a sperm cell. If the egg cell is not fertilized, it will degenerate and the menstrual cycle will begin again.
