Penile septum

The septum of the penis: anatomical formation and its role

The septum of the penis, also known as septum penis, pna, bna or septum pectiniforme corporis cavernosi penis, jna, is an important anatomical element of the male reproductive organ. It is a vertical wall separating the corpora cavernosa of the penis - special cavities filled with blood during an erection.

The septum of the penis consists of connective tissue and is located inside the cavernous bodies of the penis. Its structure resembles a comb, which explains its alternative name - septum pectiniforme. This special anatomical structure is important for the functioning of the penis and a man's sexual performance.

One of the main functions of the penile septum is to maintain the rigidity and erection of the penis. During sexual arousal, signals from the head of the penis are transmitted to the central nervous system, which causes dilation of the arteries that supply the corpora cavernosa. Blood fills the cavities of the corpora cavernosa, and the penile septum plays a role in retaining the blood within each corpora cavernosa. This helps maintain an erect penis during sexual intercourse.

In addition, the penile septum also plays a role in preventing curvature of the penis during erection. Due to its structure and anatomical location, it helps ensure uniform filling of the corpora cavernosa of the penis with blood, which helps maintain the straight shape of the penis during erection.

Despite the importance of the penile septum, it does not usually attract much attention or cause problems in men. However, some developmental abnormalities or injuries can lead to septal defects or dysfunction. In such cases, erection problems, penile curvature, or other sexual dysfunctions may occur. In such situations, medical intervention may be required to correct these problems.

In conclusion, the penile septum is an important anatomical element of the male reproductive organ that plays a role in maintaining the erection and shape of the penis. Its structure and function ensure the normal functioning of the penis during sexual intercourse. Although it usually does not cause problems, some abnormalities or injuries may require medical attention.



Although a genital septum is a common disease that every urologist has heard about, it cannot always be detected by carefully palpating a person’s reproductive system. Such a septum can be called a vestigial organ, since it consists of small cells and is practically no different in appearance from the surrounding tissues. The septum of the penis prevents the penetration of sperm from one embryo sac to another. The partition is located near
