What process occurs when a follicle reaches an egg cell?

When a follicle reaches maturity, it undergoes a process called ovulation, during which it releases an egg cell (oocyte) from the ovary. This mature follicle, now called a graafian follicle, bursts to expel the egg into the fallopian tube, where it may encounter sperm for potential fertilization. The remaining follicular cells transform into the corpus luteum, which produces hormones like progesterone to support a potential pregnancy. If fertilization does not occur, the corpus luteum degenerates, leading to menstruation.
