Internal sexual organs of the man

In testes and epididymis sperm are produced and stored. Seminal vesicles, prostate and cowper glands organize the arduous journey of swift swimmers.

Internal sexual organs of the man

In contrast to women, the male has some important reproductive organs externally visible, namely penis and scrotum. Inside his body are still testicles and epididymides, vas deferens and the so-called accessory sexual glands (seminal vesicles, prostate and cowper glands) in the service of reproduction.

Testes and epididymis

The couple testicle are the sperm production factory. Here, a healthy, young man produces nearly 130 million small swimmers a day. That this important part of the male anatomy is not well protected in the abdomen, but is outsourced to the scrotum, has its reason: The body temperature of 37° C is the sperm cells too warm. They prefer a few degrees cooler than the scrotum can provide. That is why they are stored here until further use: From the scrotum, the sperm get into the epididymisThey sit like a crooked beanie on their testicles. Here they mature further and wait for the next ejaculation.

If it actually happens, shoot the sperm from the epididymis on the vas deferens into the urethra, which they pass through the penis into the vagina - and at a speed of 17 km / h. On the way from the epididymis to the penis, the sperm are still of the accessory gonads - Seminal vesicles, prostate, cowper glands - equipped with all sorts of tools and power food for their demanding mission.

seminal vesicles

The couple seminal vesicles (Seminal glands) are about five inches long, tortuous glands that lie between the bladder and rectum. Their secretions, which they release into the vas deferens, account for about 60 percent of the ejaculated semen volume. It consists mostly of a viscous liquid that is slightly alkaline (basic). This can neutralize the acidic environment in the male urethra and female abdomen. This is important because a high acidity would inactivate and kill the sperm.

In addition, stuck in the secretion of seminal vesicles fructose (fructose), hormones (called prostaglandins) and coagulation proteins. The fructose ensures that the sperm does not run out of energy to swim - a teaspoon of sperm has about five calories. The prostaglandins keep the sperm mobile, increase their viability and stimulate the muscles in the female genital tract to contract - as a boost for the sperm cells in the direction of the egg. Finally, the coagulation proteins allow the semen to coagulate within 5 minutes after ejaculation, ie to clump together. What good that should be, you do not know exactly. After about 10 to 20 minutes, the sperm gets liquid again, thanks to various enzymes from the prostate secretion (including PSA).

prostate

The prostate (Prostate gland) is a chestnut-shaped gland the size of a golf ball. It sits below the bladder in front of the rectum and surrounds the urethra, that is: This leads directly through the prostate. When the sperm shoot through them during sexual intercourse, the prostate gives them a packed lunch - a milky, slightly acid secretion that contains, among other things, citric acid, various enzymes that break down proteins, and the antibiotic seminalplasmin. The citric acid can use the sperm for energy. As mentioned above, the protein-splitting enzymes such as PSA make the sperm that has clumped after ejaculation liquid again. And Seminalplasmin kills bacteria that naturally cavort in the semen and in the female abdomen.

Cowper's glands

Also the paired, pea-sized Cowper's glands below the prostate make an important contribution to reproduction. In sexual arousal, they release a clear, alkaline secretion into the urethra ("pleasure drops"). It rinses the canal, neutralizing any acid urine remains that are still there. In addition, mucus from the cowper glands makes the urethra and penis end more lubricious. And then everything is ready for the shooting ejaculate.
