If you turn over a mouse and a snake to look for their sex organs, you'd likely gain an appreciation for the diversity of genitalia in the animal world. Down near their tails, male mice have penises studded with tiny spines, and female mice have vaginas. But male snakes have a pair of penises, called hemipenes, closer to the middle of their body, and during sex, they insert one into the female's all-purpose opening.

Human reproductive systemorgan system by which humans reproduce and bear live offspring. Provided all organs are present, normally constructed, and functioning properly, the essential features of human reproduction are 1 liberation of an ovumor eggat a specific time in the reproductive cycle, 2 internal fertilization of the ovum by spermatozoa, or sperm cells, 3 transport of the fertilized ovum to the uterusor womb, 4 implantation of the blastocyst, the early embryo developed from the fertilized ovum, in the wall of the uterus, 5 formation of a placenta and maintenance of the unborn child during the entire period of gestation6 birth of the child and expulsion of the placenta, and 7 suckling and care of the child, with an eventual return of the maternal organs to virtually their original state. For this biological process to be carried out, certain organs and structures are required in both the male and the female.
