A normal reproductive cycle in humans typically includes the menstrual cycle for females, which involves the preparation of the uterus for potential pregnancy, ovulation, and the shedding of the uterine lining if fertilization does not occur. In males, the cycle involves the continuous production of sperm and the secretion of hormones like testosterone.
