Excessive prepuce is one of the culprits of many sexual dysfunction diseases. Excessive male prepuce without careful cleaning will produce prepuce scaling, leading to the occurrence of male sexual dysfunction. Therefore, male friends must be paid attention to.
Adult penises vary in size. It is generally believed that penises with smaller spreading patterns have a larger growth rate after erection, while penises with larger penises have a smaller growth rate after erection. Therefore, penises with relaxation patterns seem to have a larger difference in size, but the difference after erection is not significant. The posterior part of the penis is the penis root, the middle part is the cylindrical penis body, and the head end of the penis in the front end is the external orifice of the urethra.
The natural color of the penis consists of two penile cavernous bodies and one urethral cavernous body. The two penile cavernous bodies are parallel to the dorsal side of the penis, and are surrounded by a thick white membrane. The white membrane forms a comb-shaped diaphragm at the midline, which can communicate with the left and right cavernous bodies. At the root of the penis, the left and right cavernous bodies of the penis form cavernous feet and attach to the pubic bone. The cavernous body of the penis is composed of mostly interwoven sinusoid spaces, and is directly connected with the arteries and veins. It is the functional tissue of penis erection.
The foreskin is a layer of skin covering the outside of the penis. When the foreskin is turned over, it can be seen that the glans covertly presents a circular narrowing part called the coronal groove. Most of the sebaceous glands in the skin beside the coronary groove secrete a smelly secretion in the form of yellow and white mud, called "prepuce scale".
Phimosis refers to that the mouth of the foreskin is too small, which makes the foreskin taboo to turn up and swing the penis head; If the foreskin is too long, it means that the foreskin covers the penis carefully, and the foreskin mouth is not small, which can turn up and swing the penis. Too long prepuce of infants and young children is always physiological. After youth, the penis still hesitates to play its role, which is called phimosis or too long prepuce.
