Reproduction is the process by which organisms make more organisms like themselves. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive.

Human reproductive system , organ 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 ovum , or egg , at 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 uterus , or 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 gestation , 6 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.
