To regenerate and maintain the continuity of species, every living thing is equipped with a reproductive system. The human reproductive organs in men consist of several parts, each of which has a function that supports each other in producing regenerating cells. The parts of the male reproductive organs are divided into two groups, namely the internal and external genitalia.
The testes are the initial tissue in the human reproductive organs in men. The number is a pair. This gland is covered by a kind of skin pouch called the scrotum. The scrotum is located under the abdomen.
The testes are the site of sperm production (spermatogenesis). In humans, and mammals in general, the process of sperm production takes place well if the testes are in an environment of less than 37 degrees Celsius.
The testes are connected to the body via the spermatic tubules. The spermatic tubule contains the cremaster muscle. When a contraction occurs, the testes will be lifted closer to the body. When relaxed, the testes descend and move away from the body. This muscle movement is known as the cremaster reflex.
The difference in the anatomical structure of the blood vessels in the left and right testes causes the two testes to have different sizes. The main function of the testes is to produce spermatozoa and the hormone testosterone. The work process and testicular function is controlled by the gonadotropin hormone produced by the anterior pituitary gland.
There is a fibrous layer that covers the testes. This layer is called the tunica albuginea. Inside the testes are the seminiferous tubules, a tube filled with sperm. If a large number of sperm have been produced, the seminiferous tubules will automatically increase in size, and cause the scrotum to look tight. In the seminiferous tubules there are Leydig interstitial cells which have the function of producing the hormone testosterone.
The process of sperm production (spermatogenesis) begins at puberty. The maximum production process occurs when humans are sleeping. When you wake up in the morning, the scrotum is most often found to look tight.
This is because the process of sperm production takes place maximally during sleep. Therefore, the quality and quantity of a person's sleep affects the sperm count, apart from the adequacy of nutrition and nutrients absorbed by the body.
Still in the scrotum, there are a pair of ducts that come out of the testes, one each located in the right scrotum and left scrotum. This channel is called the epididymis which is shaped like a tortuous channel. This channel stores sperm from the testes. Apart from being a place to store, the epididymis is a channel for sperm maturation.
Once in the epididymis, the sperm will flow through the vas deferens. The vas deferens is a connecting channel between the epididymis and the prostate gland. The shape of the vas deferens is straight and pointed upwards.
The vas deferens is sometimes referred to as a continuation of the epididymal duct, but the vas deferens does not store sperm. The end of the vas deferens is in the semen sac / seminal vesicle (seminal vesicle) located in the prostate gland.
The ejaculatory duct is the last channel of the sperm production process. This channel is a liaison with the urethra, where the urethra is also a channel for urine output (urine). The ejaculatory duct directs sperm to enter the urethra.
S*x Glands
Human reproductive organs in men are equipped with s*x glands. This gland has a function in the transportation of sperm to be released during ejaculation. The male s*x glands consist of the seminal vesicles, prostate, and bulbourethral.
The seminal vesicles are the reservoir for sperm. It is located behind the bladder. In the seminal vesicles, sperm get various nutrients in the maturation process. About 60% of semen is produced by the seminal vesicles.
Substances such as mucus, fructose, ascorbic acid, prostaglandins, and coagulation enzymes are produced by the seminal vesicles. Fructose is a sugar compound that is useful as an energy source for sperm.
In addition to nutrients that come from the seminal vesicles, sperm also get some important substances from the prostate gland. The prostate gland secretes a fluid in which there are anticoagulant enzymes, citrate, cholesterol, salts and phospholipids. This liquid is white like milk, watery, and alkaline. This fluid is known as semen.
The main function of semen is as a medium / solvent for sperm. Semen can be interpreted as a vehicle for sperm to reach the goal. In semen, sperm will get a substrate containing sodium and potassium chloride.
Sodium and chloride function as electrolytes so that sperm can move quickly. The substrate also contains citric acid, fructose, inositol, ergonomics and phosphatases, nitrogen, ascorbic acid, and several vitamins.
The secondary function of semen is as a lubricant in sexual intercourse. This lubricant is useful so that the reproductive organs are not injured during sexual intercourse. Semen fluid that functions as a lubricant will come out the first time when someone experiences stimulation. The discharge of semen as a lubricant is not ejaculation, but this semen also contains sperm.
Just before ejaculation, the s*x glands secrete clear mucus. Clear mucus is produced by the bulbourethral glands. This fluid is alkaline and serves as a lubricant for the urethra when sperm comes out. The urethra is the channel used for the release of sperm as well as for the excretion of urine (urine).
Although it can not come out together with sperm, urine can come out in a relatively close time with the release of sperm during ejaculation. Urine is acidic and can kill sperm. Therefore, clear mucus comes out so that the urine remaining in the urethra can be neutral.
External genitalia
The outermost duct for sperm production is found in the penis. The penis is outside the human skeletal space, therefore the penis is referred to as an external organ. Basically, the penis is a tissue composed of muscles and blood vessels. The penis is divided into three parts, namely the two corpus cavernosa (located at the top), and the corpus spongiosum.
The corpus spongiosum is the tissue that protects the urethra. The penis contains erectile tissue that surrounds the urethra. In the erectile tissue there are many blood vessels and sensory nerves, therefore the penis is very sensitive to stimulation. When there is stimulation, blood will flow quickly and fill the vessels in the erectile tissue, causing the penis to expand and tense. This phase is referred to as an erection.
The scrotum is also known as the testicles. The tissues that make up the scrotum are skin and muscle. Generally, the human scrotum consists of two pieces, right and left. The two are attached to each other and separated by a septum of connective tissue and dartos muscle. The dartos muscle is a smooth muscle. This muscle regulates when the scrotum is relaxed and when to contract.
In addition to the dartos muscle, there is also the cremaster muscle. The cremasteric movement is a movement by the cremaster muscle, which is the movement of the scrotum away from or toward the body.
This movement serves to keep the temperature in the scrotum stable so that the testes can function normally. Body temperature regulation is also carried out by the skin tissue around the scrotum. In addition to having pores, the skin tissue around the scrotum is covered with hair. The hair is called pubic, but is often also referred to as pubic hair.
Reproductive Organs and Body Functions
Spermatozoa will come out if they get sexual stimulation. This sperm comes out through the medium of semen (semen), which is a thick clear liquid (sometimes a little white). Apart from being an intermediary for the release of sperm, semen has a function as a lubricant in sexual intercourse.
Sometimes this semen comes out by itself if the body experiences extreme physical exhaustion. However, if there is no activity that causes sperm to come out, the sperm will still be in the reproductive organs. Then, the body will automatically carry out its function to reabsorb sperm.
An important factor of the onset of sexual arousal is brain stimulation. Brain stimulation of sexual stimulation will work well if the sex hormones are produced properly too. Puberty is a time when sex hormones begin to increase significantly.
As part of family planning efforts, vasectomy is one way to prevent sperm from leaving the body. Vasectomy is not an attempt to sterilize because the testicles still work to produce sperm normally. The functions of the sex glands in producing sex hormones are still running.
What happens in a vasectomy is to bind or close the vas deferens channel so that sperm does not travel out. The success rate of vasectomy is very high reaching more than 90%. Side effects are also almost non-existent. Vasectomy has no effect on weight or emotional stability of a person.
Maintaining a healthy body is the best way for the human reproductive organs to function properly. In contrast to women, the reproductive organs in men will continue to work without age restrictions starting from puberty.
The intake of nutrients and nutrients contained in food greatly affects the quality of sperm. Meanwhile, regular exercise helps increase oxygen circulation in the blood so that the reproductive organs can carry out their functions properly.
