This page lists and explains the parts and functions of the male reproductive system. These are for the purposes of education and knowledge.
Male reproduction is not confined to those that are visible. Many organs serve significant functions in making a man complete. These are tiny positions, yet they are all important.
The penis and scrotum are the man’s exterior organs or genitals, but this does not mean that they are the only ones on the list.
Male Reproductive System Parts and Functions
Even a toddler can recognize this as the most prevalent organ in a man’s body. It’s a spongy tissue that fills with blood and stands upright when either filled with urine or stimulated.
The penis is made of several parts:
- Glans (head) of the penis: In uncircumcised men, the glans is covered with pink, moist tissue called mucosa. Covering the glans is the foreskin (prepuce). In circumcised men, the foreskin is surgically removed and the mucosa on the glans transforms into dry skin.
- Corpus cavernosum: Two columns of tissue running along the sides of the penis. Blood fills this tissue to cause an erection.
- Corpus spongiosum: A column of sponge-like tissue running along the front of the penis and ending at the glans penis; it fills with blood during an erection, keeping the urethra — which runs through it — open.
- The urethra runs through the corpus spongiosum, conducting urine out of the body.
Every man has a sac-like organ right below his penis. The testes are two balls that are contained in this sac. The scrotum sac’s primary function is to protect the testes from extreme temperatures. It protects the testes by housing them and keeping them healthy. Because it can be so dangerous, it’s rare to find folks who have problems with their scrotum sac.
Each side of the scrotum usually consists of a:
- Testicle. Each testicle produces hormones, the main one being testosterone, with the help of parts of the brain like the hypothalamus and pituitary gland. They also contain tubules and cells that produce sperm, or spermatozoa. Sperm are transferred from the testicle to the epididymis.
- Epididymis. An epididymis is located on the top of each testicle. Each epididymis is a tightly coiled tube. They store sperm created in each testicle until they’re mature, usually for about 60 to 80 days. The epididymis also absorbs extra fluid secreted by the testicle to help move sperm through the reproductive tract.
- Spermatic cord. Each spermatic cord contains blood vessels, nerves, lymph vessels, and a tube called the vas deferens. This tube moves sperm out of the epididymis into ejaculatory ducts. The blood vessels maintain the blood supply for the testicle, vas deferens, and cremaster muscle. The nerves transport information from the spinal cord to and from the scrotum, testicles, and cremaster muscle.
- Cremaster muscle. Each cremaster muscle surrounds one of the testicles and its spermatic cord. The muscle helps to move the testicle toward and away from the body to maintain the ideal temperature for sperm production. This is why the scrotum hangs lower in warm conditions and closer to the body in cold weather.
These are the two male testicles, which serve as the man’s sperm factory. Seminiferous tubules, which create sperm, are densely packed in the testes.
These tubules connect to a tangle of ducts that feed into a single storage tube on the surface of each testis termed the ‘epididymis.’
The size of the penis is frequently used to determine the size of the urethra. In a male, it is the channel for both urine and sperm.
Despite the fact that the semen and urine run through the same tube, the urethra is structured in such a manner that they do not mix. This is made possible by several muscles that govern the flow of the semen and urine into the urethra.
The Cowper’s Gland
These are twin small structures that flank the Urethra.These glands release a transparent fluid that appears like mucus when a guy is aroused.
This fluid is generally found at the penis’s tip. The major reason for this pre-ejaculatory fluid has not been confirmed scientifically up to this point, however it is commonly assumed to lubricate the urethra in order to facilitate sperm passage.
This fluid transports sperm in some men and does not in others. However, because this liquid can carry sperm, the withdrawal technique of contraception is unreliable because it only blocks the actual discharge of sperm into the body while ignoring the pre-ejaculation fluid, which may contain sperm.
The Prostate Gland
This is the organ responsible for the production of some of the fluid in the semen that nourishes and transports sperm.
The Seminal Testicles
These are the two organs in the prostate glands whose secretion provides nutrients to the semen. The tubes of the seminal vesicle and the vas deferens on each side lead to the ejaculatory duct.
The Vas Deferens
This is a tube that rises into the abdominal cavity.
