The hormonal cycle, also known as the menstrual cycle, is a complex physiological process that prepares a woman's body for pregnancy. It is regulated by a series of hormonal changes that occur throughout the cycle. The cycle begins with the shedding of the uterine lining during menstruation, followed by the growth and development of the ovarian follicle, and ovulation. The post-ovulatory phase involves the production of progesterone to support the potential implantation of a fertilized egg. Understanding the hormonal cycle is crucial for the management of reproductive health issues and family planning.
