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.
The external structures of the male reproductive system are the penis, the scrotum and the testicles. Penis — The penis is the male organ for sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped end of the penis.
Cancer occurs when cells in the body grow out of control. Cancers are named for the part of the body where they start. Reproductive cancers are cancer that is in the organs related to reproduction.
The reproductive system is necessary for the production of new living organisms. The reproductive system is comprised of male and female reproductive organs and structures. Both male and female reproductive organs have internal and external structures.

The human reproductive system functions to produce human offspring, with the male providing sperm and the female providing the ovum. While the ultimate purpose of the human reproductive system is to produce offspring, the proximate purpose is to produce pleasure and induce bonding. This can be seen in our closest relatives, the bonobo chimpanzees, who have sex for a wide variety of reasons including pleasure, bonding, and alleviating tension in addition to producing offspring.
The more usual term is genitals. In men this sex organ is called a testicle, and in women it is called an ovary. British very informal testicles.
Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Historically, the term hermaphrodite has also been used to describe ambiguous genitalia and gonadal mosaicism in individuals of gonochoristic species, especially human beings. The word intersex has come into preferred usage for humans, since the word hermaphrodite is considered to be misleading and stigmatizing,   as well as "scientifically specious and clinically problematic.
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. In the human reproductive process, two kinds of sex cells, or gametes pronounced: GAH-meetzare involved.
Hermaphroditismthe condition of having both male and female reproductive organs. Hermaphroditic plants —most flowering plants, or angiosperms —are called monoecious, or bisexual. Hermaphroditic animals—mostly invertebrates such as wormsbryozoans moss animalstrematodes flukessnailsslugsand barnacles —are usually parasitic, slow-moving, or permanently attached to another animal or plant. In humans, conditions that involve discrepancies between external genitalia and internal reproductive organs are described by the term intersex.
