The Male Reproductive System
The purpose of the organs of the male reproductive system is to perform the following functions:
- To produce, maintain, and transport gamete (the male fruitful cells) and protecting fluid (semen)
- To discharge gamete among the feminine fruitful tract throughout sex
- To produce and secrete male sex-hormones chargeable for maintaining the male system
- Unlike the female reproductive system, most of the male reproductive system is located outside of the body. These external structures include the penis, scrotum, and testicles.
The Male Reproductive System
This is the male organ employed in sexual activity. it’s 3 parts: the foundation, that attaches to the wall of the abdomen; the body, or shaft; and also the bodily structure, that is that the round shape half at the tip of the erectile organ. The glans, additionally known as the top of the erectile organ, is roofed with a loose layer of skin known as foreskin. This skin is typically removed in an exceedingly procedure known as circumcision. The gap of the canal, the tube that transports bodily fluid and pee, is at the tip of the erectile organ. The bodily structure of the erectile organ additionally contains variety of sensitive nerve endings.
The body of the erectile organ is cylindrical in form and consists of 3 circular formed chambers. These chambers square measure created from special, sponge-like tissue. This tissue contains thousands of enormous areas that fill with blood once the person is sexually aroused. because the erectile organ fills with blood, it becomes rigid and erect, that permits for penetration throughout sexual activity. The skin of the penis is loose and elastic to accommodate changes in erectile organ size throughout an erection.
Semen, that contains sperm cell (reproductive cells), is expelled (ejaculated) through the tip of the erectile organ once the person reaches coming (orgasm). once the erectile organ is erect, the flow of pee is blocked from the canal, permitting solely bodily fluid to be ejaculated at climax.
This is the loose pouch-like sac of skin that hangs behind and below the erectile organ. It contains the testicles (also known as testes), additionally as several nerves and blood vessels. The pouch acts as a “climate management system” for the testes. For normal sperm development, the testes should be at a temperature slightly cooler than blood heat. Special muscles within the wall of the pouch enable it to contract and relax, moving the testicles nearer to the body for heat or farther off from the body to cool down the temperature.
These square measure oval organs concerning the dimensions of huge olives that lie the pocket, secured at either finish by a structure referred to as the spermatic cord. Most men have 2 testes. The testes square measure answerable for creating androgenic hormone, the first male endocrine, and for generating spermatozoon. among the testes square measure whorled plenty of tubes referred to as body fluid tubules. These tubes square measure answerable for manufacturing spermatozoon cells.
The internal organs of the male system, conjointly referred to as accent organs, embrace the following:
The duct could be a long, whorled tube that rests on the backside of every testis. It transports and stores spermatozoon cells that area unit made within the testes. It is also the task of the duct to bring the spermatozoon to maturity, since the spermatozoon that emerge from the testes area unit immature and incapable of fertilization. throughout arousal, contractions force the spermatozoon into the vas deferens.
The vas deferens is a long, muscular tube that travels from the canal into the cavity, to only behind the bladder. The vas deferens transports mature spermatozoon to the epithelial duct, the tube that carries urine or sperm to outside of the body, in preparation for ejaculation.
These area unit fashioned by the fusion of the epithelial duct and also the seminal vesicles (see below). The ejaculatory ducts empty into the channel.
The duct is that the tube that carries excrement from the bladder to outside of the body. In males, it’s the extra operate of ejaculating bodily fluid once the person reaches climax. once the erectile organ is erect throughout sex, the flow of excrement is blocked from the duct, permitting solely bodily fluid to be ejaculated at climax.
The seminal vesicles area unit sac-like pouches that attach to the canal close to the bottom of the bladder. The seminal vesicles turn out a sugar-rich fluid (fructose) that gives sperm cell with a supply of energy to assist them move. The fluid of the seminal vesicles makes up most of the quantity of a man’s ejaculatory fluid, or ejaculate.
The prostate could be a walnut-sized structure that’s set below the bladder ahead of the body part. The prostate contributes further fluid to the ejaculate. Prostate fluids additionally facilitate to nourish the gamete. The duct, that carries the ejaculate to be expelled throughout consummation, runs through the middle of the prostate.
Also referred to as Cowper’s glands, these area unit pea-sized structures situated on the perimeters of the epithelial duct slightly below the endocrine gland. These glands manufacture a transparent, slippery fluid that empties directly into the epithelial duct. This fluid serves to lubricate the epithelial duct and to neutralize any acidity that will be gift thanks to residual drops of excrement within the epithelial duct.
How Does the Male Reproductive System Function?
The entire male genital system relies on hormones, that are chemicals that regulate the activity of the many differing types of cells or organs. the first hormones concerned within the male genital system are FSH, ICSH, and androgen.
Follicle-stimulating hormone is critical for sperm cell production (spermatogenesis), and ICSH stimulates the assembly of androgen, that is additionally required to form sperm cell. androgen is answerable for the event of male characteristics, together with muscle mass and strength, fat distribution, bone mass, facial hair growth, voice modification, and drive.
