The male reproductive system can be divided into two parts: the external reproductive system and the internal reproductive system. The external structures include the penis, scrotum, and testicles; the internal structures include the vas deferens, urethra, prostate, and seminal vesicles.
The Penis
The Penis consists of the base, body and head (glans). The urethra is the passage that discharges urine and semen. It opens at the front of the glans penis. The bottom of the glans penis is called the coronal sulcus and is covered by the foreskin.
The penis is composed of the corpus spongiosum. When the spaces in the corpus cavernosum are filled with blood, the penis will become erect and become thicker and harder. Lymph is the fluid found in lymph glands. It mainly contains some protein and fat.
Scrotum
Scrotum is a thin sac of skin that surrounds and protects the testicles.
Testicle
Oval in shape, with an attached testicle located above the testicle.
Vas deferens
It is a cord-like tube that transports sperm through the attached testes. Other structures such as blood vessels and nerves also form a cord-like structure called the spermatic cord.
Prostate
In the pelvic cavity, located under the bladder and surrounding the posterior urethra, it is about the size of a walnut and will grow with age.
Have sex
During sexual activity, the penis becomes hard and erect, and can be inserted into the vagina during sexual intercourse. The interaction of nerves, blood vessels, hormones, psychology, and other factors causes erections.
Ejaculation occurs when the head of the penis is rubbed or reaches orgasm due to sexual excitement. After ejaculation or stimulation, the penile arteries contract and the veins relax. The blood flow into the penis decreases, while the outflow blood flow increases, and the penis becomes weak and returns to its original state.
Nursing aspects
The foreskin should be checked regularly and kept clean on weekdays, and appropriate measures for safe sex should be taken.
The Male Reproductive System – Prevention
The male reproductive system – Men under the age of 40 should have their testicles checked once a month to detect testicular cancer early. During self-examination, hold the testicles with your thumb and other fingers and rotate them. You should see a doctor if you find lumps, tissue changes, swelling, or tingling.
