Ejaculation , the release of sperm cells and seminal plasma from the male reproductive system. Sperm cells that are stored in the male body are not capable of self-movement because of the acidity of the accompanying fluids. When the sperm receive fluids, called seminal plasma , from the various internal accessory organs prostate gland , ejaculatory ducts , seminal vesicles , and bulbourethral glands , the acidity decreases. As they leave the body, the sperm receive oxygen , which is vital to motility. Unable to leave the male body by their own motivation, the sperm cells are transported by muscular contractions.

Unlike the female genitalia , the male reproductive organs are on both the interior and the exterior of the pelvic cavity. They include:. Sperm production occurs in the testicles. Upon reaching puberty , a man will produce millions of sperm cells every day, each measuring about 0. There is a system of tiny tubes in the testicles. These tubes, called the seminiferous tubules, house the germ cells that hormones — including testosterone , the male sex hormone — cause to turn into sperm.

The germ cells divide and change until they resemble tadpoles with a head and short tail. The tails push the sperm into a tube behind the testes called the epididymis. For about five weeks, the sperm travel through the epididymis, completing their development. Once out of the epididymis, the sperm move to the vas deferens. When a man is stimulated for sexual activity, the sperm are mixed with seminal fluid — a whitish liquid produced by the seminal vesicles and the prostate gland — to form semen.

As a result of the stimulation, the semen, which contains up to million sperm , is pushed out of the penis ejaculated through the urethra. The process of going from a germ cell to a mature sperm cell capable of egg fertilization takes around 2. Sperm are produced in the testicles and develop to maturity while traveling from the seminiferous tubules through the epididymis into the vas deferens.

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-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 ZYE-goat. The zygote goes through a process of becoming an embryo and developing into a fetus.

The male reproductive system and the female reproductive system both are needed for reproduction. Humans, like other organisms, pass some characteristics of themselves to the next generation. We do this through our genes , the special carriers of human traits.

The genes that parents pass along are what make their children similar to others in their family, but also what make each child unique. These genes come from the male's sperm and the female's egg. The male has reproductive organs, or genitals, that are both inside and outside the pelvis.

The male genitals include:. In a guy who has reached sexual maturity , the two oval-shaped testicles , or testes TESS-teez make and store millions of tiny sperm cells. The testicles are also part of the endocrine system because they make hormones , including testosterone tess-TOSS-tuh-rone.

Testosterone is the hormone that causes boys to develop deeper voices , bigger muscles, and body and facial hair. It also stimulates the production of sperm. Alongside the testicles are the epididymis and the vas deferens, which transport sperm. The epididymis ep-uh-DID-uh-miss and the testicles hang in a pouch-like structure outside the pelvis called the scrotum.

This bag of skin helps to regulate the temperature of testicles, which need to be kept cooler than body temperature to produce sperm. The scrotum changes size to maintain the right temperature.

When the body is cold, the scrotum shrinks and becomes tighter to hold in body heat. When it's warm, it gets larger and floppier to get rid of extra heat.

This happens without a guy ever having to think about it. The brain and the nervous system give the scrotum the cue to change size. The accessory glands , including the seminal vesicles and the prostate gland , provide fluids that lubricate the duct system and nourish the sperm. The urethra is the channel that carries the sperm in fluid called semen to the outside of the body through the penis.

The urethra is also part of the urinary system because it is also the channel through which pee passes as it leaves the bladder and exits the body. The penis is actually made up of two parts: the shaft and the glans. The shaft is the main part of the penis and the glans is the tip sometimes called the head. At the end of the glans is a small slit or opening, which is where semen and urine exit the body through the urethra yoo-REE-thruh.

The inside of the penis is made of a spongy tissue that can expand and contract. All boys are born with a foreskin , a fold of skin at the end of the penis covering the glans. Some boys are circumcised, which means that a doctor or clergy member cuts away the foreskin. Circumcision is usually done during a baby boy's first few days of life.

It's not medically necessary, but parents who choose to have their sons circumcised often do so based on religious beliefs, concerns about hygiene, or cultural or social reasons.

Boys who have circumcised penises and those who don't are no different: All penises work and feel the same, regardless of whether the foreskin has been removed. When a baby boy is born, he has all the parts of his reproductive system in place, but it isn't until puberty that he is able to reproduce. When puberty begins, usually between the ages of 9 and 15, the pituitary gland — located near the brain — secretes hormones that stimulate the testicles to produce testosterone.

The production of testosterone brings about many physical changes. A male who has reached puberty will produce millions of sperm cells every day. Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells. During puberty, testosterone and other hormones cause these cells to transform into sperm cells. The cells divide and change until they have a head and short tail, like tadpoles.

The head contains genetic material genes. The sperm move into the epididymis, where they complete their development. The seminal vesicles and prostate gland make a whitish fluid called seminal fluid, which mixes with sperm to form semen when a male is sexually stimulated. The penis, which usually hangs limp, becomes hard when a male is sexually excited. Tissues in the penis fill with blood and it becomes stiff and erect an erection. The rigidity of the erect penis makes it easier to insert into the female's vagina during sex.

When the erect penis is stimulated, muscles around the reproductive organs contract and force the semen through the duct system and urethra. Semen is pushed out of the male's body through his urethra — this process is called ejaculation.

Each time a guy ejaculates, it can contain up to million sperm. If semen is ejaculated into a female's vagina, millions of sperm "swim" up from the vagina through the cervix and uterus to meet the egg in the fallopian tube.

It takes only one sperm to fertilize the egg. This fertilized egg is now called a zygote and contains 46 chromosomes — half from the egg and half from the sperm.

Genetic material from the male and female combine so that a new individual can be created. The zygote divides again and again as it grows in the female's uterus, maturing over the course of the pregnancy into an embryo, a fetus, and finally a newborn baby. Reviewed by: Larissa Hirsch, MD.
