Ovulation is a crucial process in a woman's reproductive system that occurs monthly. It's when a mature egg is released from the ovary and travels through the fallopian tube, where it may be fertilized by sperm. The egg then travels to the uterus, where it may implant in the uterine lining and result in pregnancy. The ovulation cycle is the process that leads up to ovulation and the hormonal changes that occur during this time. It typically occurs every 28 days and is divided into three phases: the follicular phase, ovulation, and the luteal phase. The follicular phase is the first phase of the cycle and starts on the first day of menstruation. During this time, the body is preparing for ovulation by increasing the levels of follicle-stimulating hormone (FSH). This hormone stimulates the growth of follicles in the ovaries, which contain immature eggs. By the end of this phase, one of the follicles will have matured into a dominant follicle, which will release an egg during ov
