All living things reproduce. Reproduction — the process by which organisms make more organisms like themselves — is one of the things that sets living things apart from nonliving things. In the human reproductive process, two kinds of sex cells, or gametes, are involved. Both the male and female reproductive systems are essential for reproduction. Humans pass certain characteristics of themselves to the next generation through their genes, the special carriers of human traits. Most species have two sexes: male and female.

NCBI Bookshelf. The male sex organs allow men to have children. But they have other important jobs, too: The sex organs produce hormones, control the process of boys maturing into grown men, and make sex and sexual pleasure possible. Like women, men have external and internal sex organs. The external male sex organs include the penis and the scrotum. The main purpose of the external sex organs is to allow for sexual intercourse and sexual pleasure. The structure of the penis is similar to that of the female clitoris, apart from the fact that the clitoris is mostly inside the body.
Men's sexual organs
The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body and within the pelvis. The main male sex organs are the penis and the testicles which produce semen and sperm , which, as part of sexual intercourse , fertilize an ovum in the female's body; the fertilized ovum zygote develops into a fetus , which is later born as an infant. The corresponding system in females is the female reproductive system. The penis is the male intromittent organ.
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. The glans, which also is called the head of the penis, is covered with a loose layer of skin called foreskin.
