Ejaculationthe release of sperm cells and seminal plasma from the male reproductive system. Ejaculation takes place in two phases: in the first, or emission, stage, sperm are moved from the testes and the epididymis where the sperm are stored to the beginning of the urethraa hollow tube running through the penis that transports either sperm or urine; in the second stage, ejaculation proper, the semen is moved through the urethra and expelled from the body. Sperm cells that are stored in the male body are not capable of self-movement because of the acidity of the accompanying fluids.
The bag of skin that holds and helps to protect the testicles. The testicles make sperm and, to do this, the temperature of the testicles needs to be cooler than the inside of the body. This is why the scrotum is located outside of the body.

The epididymis plural, epididymides is a tightly coiled mass of thin tubes that carries sperm from the testes to the ductus deferens in the male reproductive system. Sperm matures as it passes through the epididymis so that it is ready to fertilize ova by the time it enters the ductus deferens. The epididymis is a crescent-shaped coil of thin tubules located inside the scrotum and posterior to the testis.
Error: This is required. Error: Not a valid value. The male reproductive system contains the external genitals the penis, testes and the scrotum and internal parts, including the prostate gland, vas deferens and urethra.
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 GAH-meetzare 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.
