Common problems include infertility, prostate disease, impotence, loss of sex ...In humans, female and male reproductive systems work together to reproduce. There are two kinds of sex cells — sperm and eggs. When a sperm meets an egg, it can fertilize it and create a zygote. This zygote eventually becomes a fetus. Both a sperm and an egg are needed for human reproduction. Classify these organs as male or female reproductive structures: ovaries, penis, scrotum, testes, vagina, uterus.
