Male Reproductive System
Reproductive system
- They turn out, maintain, and transport gametes (the male procreative cells) and humor (the protecting fluid around sperm).
- They discharge gametes into the feminine reproductive tract.
- They turn out and secrete male sex hormones.
- The male system is formed of internal (inside your body) and external (outside your body) elements. Together, these organs assist you in urinating (rid your body of liquid waste materials), having sex, and creating kids.

Male system function
The entire male system depends on hormones. These are the chemicals that stimulate or regulate the activity of your cells or organs. The first hormones concerned with the functioning of the male system are FSH (FSH), gonadotrophic hormone (LH), and androgenic hormone.
FSH and interstitial cell-stimulating hormones are created by the endocrine system. It’s placed at the bottom of your brain, and it’s responsible for several functions in your body. The gonadotrophic hormone is important for gamete production (spermatogenesis).
The interstitial cell-stimulating hormone stimulates the assembly of the androgenic hormone, which is important to continue the method of gametogenesis. The androgenic hormone is additionally vital in the development of male characteristics, together with muscle mass and strength, fat distribution, bone mass, and drive.
External male reproductive structures
Most of the male system is found outside of your cavum or pelvis. The external elements of the male system embody the phallus, the pouch, and also the testicles.
Penis
The phallus is the male organ of sexuality. it's 3 parts:
The root
This is often part of the phallus that attaches to the wall of your abdomen.
The body or shaft
The body of the phallus is made up of three internal chambers and is shaped like a tube or cylinder. Within these chambers, there’s a special, sponge-like animal tissue that contains thousands of huge areas that fill with blood once you’re sexually aroused. Because the phallus fills with blood, it becomes rigid and erect, which permits penetration throughout sex. The skin of the phallus is loose and elastic, allowing changes in phallus size throughout an associate degree erection.
The glans
This is often the conical finish of the phallus. The glans, which is additionally known as the pinnacle of the phallus, is roofed with a loose layer of skin known as the foreskin. This skin is typically removed in a procedure known as circumcision. The gap of the epithelial duct — the tube that transports each humor and body waste out of the body — is found at the tip of the glans. The phallus jointly contains several sensitive nerve endings.
Semen, which contains gametes, is expelled (ejaculated) through the tip of the phallus once a person reaches orgasm (orgasm). Once the phallus is erect, the flow of body waste is blocked from the epithelial duct, permitting only humor to be ejaculated at the climax.
Scrotum
The pouch is the loose, pouch-like sac of skin that hangs behind the phallus. It holds the testicles (also known as testes), as well as several nerves and blood vessels. The pouch protects your testes, furthermore providing a form of the immune system. For traditional gamete development, the testes should be at a temperature slightly more remarkable than the vital sign.
Special muscles within the wall of the pouch permit it to contract (tighten) and relax, moving the testicles nearer to the body for heat and protection or farther away from the body to cool down the temperature.
Anatomy of the Male Reproductive System
Testicles (testes)
The testes are square organs with the dimensions of terribly massive olives that be the pouch, secured at either end by a structure known as the funiculus. Most men have two testes.
The testes are responsible for creating the androgenic hormone, the first male steroid hormone, and manufacturing gametes. There are square measures of coiled lots of tubes known as humor tubules inside the testes.
These tubules are responsible for manufacturing the gamete cells through a method known as gametogenesis.
Epididymis
The epithelial duct may be a long, coiled tube that rests on the backside of every ballock. It carries and stores gamete cells that are created within the testes by a process of mitosis. It’s conjointly the work of the epithelial duct to bring the gamete to maturity — the gamete that emerges from the testes is immature and incapable of fertilization.
Internal male reproductive organs
You have many internal organs —also known as accent organs — that play a giant role within the male system. These organs include:
Vas deferens
The canal may be a long, muscular tube that travels from the epithelial duct into the bodily cavity, merely behind the bladder.
Ejaculatory ducts
These ducts are fashioned by the fusion of the canal and the seminal vesicles. The ejaculatory ducts empty into the epithelial duct.
Urethra
The epithelial duct is the tube that carries body waste from the bladder to the outside of your body. In males, it's the extra operation of emission (ejaculating) humor after you reach climax.
Seminal vesicles
The seminal vesicles are square, sac-like pouches that attach to the canal close to the bottom of the bladder. The seminal vesicles create a sugar-rich fluid (fructose) that provides the gamete with a supply of energy and helps with the sperms’ ability to maneuver (motility).
Prostate gland
The endocrine gland may be a walnut-sized structure that’s placed below the bladder before the body part The endocrine gland contributes further fluid to the ejaculate.
Bulbourethral glands
The bulbourethral glands, or Cowper’s glands, are square, pea-sized structures placed on the perimeters of the epithelial duct, slightly below the endocrine gland. These glands turn out a transparent, slippery fluid that empties directly into the epithelial duct.
