Explanation

Male: testes produce sperm and testosterone, epididymis stores sperm, vas deferens transports, seminal vesicles and prostate add fluids creating semen, penis delivers sperm.

Female: ovaries produce eggs and hormones, fallopian tubes transport egg and are site of fertilization, uterus nourishes developing fetus, vagina receives sperm and is birth canal.

Menstrual cycle (~28 days): menstruation (shedding uterine lining), follicular phase (egg matures), ovulation (egg released), luteal phase (uterus prepares for implantation). Hormones control cycle.
