MALE REPRODUCTION SYSTEM ,
PARTS
Epididymis
The epididymis is a long, coiled tube that rests on the backside of each testicle. It carries and stores sperm cells that are created in the testes. It’s also the job of the epididymis to bring the sperm to maturity the sperm that emerge from the testes are immature and incapable of fertilization. During sexual arousal, contractions force the sperm into the vas deferent.
Testicles
The testes are oval organs about the size of very large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
Urethra
The urethra is the tube that carries urine from the bladder to outside of your body. In males, it has the additional function of expelling (ejaculating) semen when you reach orgasm. When the penis is erect during sex, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.
Scrotum
The scrotum is the loose pouch-like sac of skin that hangs behind the penis. It holds the testicles, as well as many nerves and blood vessels. The scrotum protects your testes, as well as providing a sort of climate control system. For normal sperm development, the testes must be at a temperature slightly cooler than the body temperature. Special muscles in the wall of the scrotum allow it to contract and relax, moving the testicles closer to the body for warmth and protection or farther away from the body to cool the temperature.
Vas deferens:
The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra in preparation for ejaculation.
Penis
-
The body or shaft, Shaped like a tube or cylinder, the body of the penis is made up of three internal chambers. Inside these chambers there’s a special, sponge-like erectile tissue that contains thousands of large spaces that fill with blood when you’re sexually aroused..
The glans: This is the cone-shaped end of the penis. The glans, which is also called the head of the penis, is covered with a loose layer of skin called foreskin. This skin is sometimes removed in a procedure called circumcision.
Ejaculatory ducts
These ducts are formed by the fusion of the vas deferens and the seminal vesicles. The ejaculatory ducts empty into the urethra.
Seminal vesicles
The seminal vesicles are sac-like pouches that attach to the vas deferens near the base of the bladder. The seminal vesicles make fructose that provides sperm with a source of energy and helps with the sperms’ ability to move. The fluid of the seminal vesicles makes up most of the volume of your ejaculatory fluid, or ejaculate.
Prostate gland
The prostate gland is a walnut-sized structure that’s located below the urinary bladder in front of the rectum. Prostate fluids also help to nourish the sperm. The urethra, which carries the ejaculate to be expelled during orgasm, runs through the center of the prostate gland.
Bulbourethral glands
The bulbourethral glands, are pea-sized structures located on the sides of the urethra, just below the prostate gland. These glands produce a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.
FUNCTION
They produce, maintain and transport sperm (the male reproductive cells) and semen (the protective fluid around sperm).

HORMONES
The entire male reproductive system is dependent on hormones. These are chemicals that stimulate or regulate the activity of your cells or organs.
