Sperm, male sex gametes, are produced in the testicles. The testicles are in the scrotum, which looks flaccid and slightly wrinkled. It is important that they are located outside the abdomen because sperm are produced at a lower temperature than the rest of the body.
On cold days or during a cold shower, the scrotum shrinks, favoring the heating of the testicles. Wearing tight underwear can cause temporary infertility due to overheating in the testicles.
The testicles are male sex glands. They are formed by thin and bent tubes called seminiferous tubules. Contrary to what happens with girls, who are already born with “stock” of “ready” gametes (eggs) in the body, it is at puberty, under the action of hormones, that the production of gametes (sperm) begins in the male body. testicles.
Sperm production begins at puberty, around 12 or 13 years of age, and goes until the end of life. Each sperm is basically made up of three parts: head, lap and tail with flagella.
The testicles also produce the male sex hormone, called testosterone. The hormone testosterone stimulates the onset of male secondary sexual characteristics: hair on the face and the rest of the body, changes in voice etc.
Newly formed sperm are stored in the epididymis, another fold of tubules located over the testicles. Epididymis are two organs formed by coiled tubes, each located next to a testis. Review the outline of the male genital system and note the location of the epididymis.
Sperm can be stored in these tubes for approximately one to three weeks until maturation is completed. This increases your mobility.
Sperm pass from the epididymis to a muscular walled tube called vas deferens. From each epididymis a vas deferens. Subsequently and under the urinary bladder, each vas deferens joins the seminal gland canal on the same side and forms a unique tube called ejaculatory duct. The ejaculatory ducts send the sperm into another channel - the urethra. The urethra is a tube that starts in the urinary bladder, runs through the inside of the penis and opens in the external environment.
Seminal Glands and Prostate
At seminal glands They are two bag-shaped glands. They produce a dense liquid that nourishes the sperm and increases your mobility.
THE prostate It is a gland producing a milky-looking liquid. This liquid is milky and neutralizes acidity urine remains in the urethra and, in a sexual relationship, the natural acidity of the vagina, thus protecting sperm.
On their “trip” to the urethra, sperm receive the fluids produced by the seminal glands and the prostate gland. When passing through the urethra, sperm also receive a lubricating liquid produced by the bulbourethral glands.
The group formed by sperm and the fluids produced by the seminal glands, the prostate gland and the bulbourethral glands is called sperm or semen.
