Understanding the Female Reproductive Cycle

The video explains the female reproductive cycle, which includes the ovarian and menstrual cycles, regulated by hormones like FSH, LH, estrogen, and progesterone. It begins at puberty and involves changes in the ovaries and uterus lining. The cycle is typically 28 days, starting with hormone release from the pituitary gland, leading to follicle development and ovulation. If fertilization occurs, pregnancy begins; otherwise, menstruation happens, shedding the uterine lining.
