Male sex organ

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-meetz , are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes meets an egg, this fertilized egg is called a zygote pronounced: ZYE-goat. The zygote goes through a process of becoming an embryo and developing into a fetus.

The male reproductive system includes the penis, scrotum, testes, epididymis, vas deferens, prostate, and seminal vesicles. The penis and the urethra are part of the urinary and reproductive systems. The scrotum, testes testicles , epididymis, vas deferens, seminal vesicles, and prostate comprise the rest of the reproductive system. The penis consists of the root which is attached to the lower abdominal structures and pelvic bones , the visible part of the shaft, and the glans penis the cone-shaped end. The opening of the urethra the channel that transports semen and urine is located at the tip of the glans penis.

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.

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. This skin is sometimes removed in a procedure called circumcision.
