The anatomy of the penis is important for every man to know. In addition to understanding the parts of the penis and their functions, studying the anatomy of the penis will also let you know the signs of abnormality in the penis so that treatment can be done immediately.
You need to know that the average adult male penis measures about 8–9 cm in the non-erect state and 12–14.5 cm in the erect state. Many people worry about the size of his small penis. In fact, what is more important is if you have a normal penis anatomy.
Recognizing the Anatomy of the Penis
The penis has two main functions. In addition to acting as a sexual organ in men, the penis also functions as a way out of urine from the body through a channel called the urethra.
Here is a complete explanation of the anatomy of the penis:
1. Penis head
At the tip of the head of the penis, there is a small slit or opening to the urethra for urine and semen to come out. In an uncircumcised penis, the head is covered by the foreskin. At birth, the entire shaft of the penis is covered by this outer skin or foreskin.
In some men, the foreskin will be cut or circumcised, either for health, religious or cultural reasons. Circumcision performed correctly will not interfere with the function of the penis.
2. Penis shaft
The shaft of the penis is the middle part of the penis that serves as a liaison between the base of the penis and the head of the penis. The shaft of the penis is composed of tissue and blood vessels covered by skin.
3. Corpus cavernosum
Corpus cavernosum is the tissue that runs along the shaft of the penis, on the left and right sides. Before an erection occurs, this tissue will be filled with blood, so that the shaft of the penis stiffens.
4. Corpus spongiosum
Corpus spongiosum is the tissue that surrounds the urethra or urinary tract and runs along the bottom of the penis. During the erection process, corpus spongiosum serves to open the urinary tract as a way out of the ejaculated seminal fluid.
How Do Erections Happen?
Erections occur due to changes in blood flow in the penis. When a man is aroused, nerves make the blood vessels in the penis widen. The blood flow that enters will be more than that out of the penile tissue, causing the corpus cavernosum tissue to harden.
There are some common signs where the penis has a normal erection, one of which is when it gets sexual stimulation, such as watching porn, imagining or fantasizing sexually, and having sex.
Not only that, the penis is said to be normal if an erection occurs during sleep or awakens from sleep. In medical terms, this condition is called nocturnal penile tumescence (NPT).
Healthy men usually experience 3−5 erections for 25−35 minutes each during sleep. The cause is not known for sure, but this condition is considered as evidence that the penis is working properly.
In certain cases, sometimes there are some people who experience a penis bent to the right or left during an erection. It is important to understand that this condition is not always considered a serious problem.
As long as a crooked penis is not accompanied by symptoms of pain and does not experience difficulties during sexual penetration, a crooked penis does not require special treatment.
However, if you do experience a sign of abnormal penis anatomy, especially abnormalities in the shape of the penis or erectile dysfunction, it's a good idea to consult a doctor for safe and appropriate treatment.
