Penile lymphangiitis

The penis is an important part of the male body. If there is an abnormality in the male penis, it will not only affect the male's physical health, but also affect family harmony. If penile sclerosing lymphadenitis occurs, most of the time no treatment is required. This disease has a healing function and will often get better slowly after a period of time. The cause of this phenomenon is mostly frequent sexual life or too much friction.

Penile sclerosing lymphangitis belongs to the dermatology and venereology department. It is characterized by subcutaneous cord-like swellings of the penis. The tissue pathology is mainly lymphangitis. Some people also think it is Mondor's phlebitis occurring in the penis. This disease generally occurs after local abrasion caused by mild local mechanical injury, masturbation and excessive frequency and excessive force of sexual intercourse. Local trauma leads to obstruction of large lymphatic vessels in the subcutaneous tissue of the penis, resulting in local damage. Local infection of the penis is also related to this disease. It has been found that viral infections such as herpes simplex virus, chlamydia and tuberculosis infection can cause this disease. Recently, it has been found that condyloma acuminatum can cause sclerosing lymphangitis, suggesting that human papillomavirus may also be a cause of this disease.

It is common in men aged 30 to 40, and generally has no conscious symptoms. The course of the disease is self-limited, and most cases can disappear and be absorbed on their own, so this disease generally does not attract the attention of patients. The common site is the coronal sulcus, and sometimes it can also be seen on the back of the penis. Clinically, curved, earthworm-like, cartilage-hard cords can be seen, which are not adhered to the surface skin and can slide under the skin. Generally, they are tightly attached to the subcutaneous tissue, and the rash is translucent. Sometimes it is mildly painful, and occasionally ulcers can form.

The differentiation and development process of the penis is divided into four stages:

Pregnancy Week 10-12

The penis is just differentiated and is only 3.5 mm long. At this time, testosterone is produced under the action of hCG secreted by the placenta.

The second and third trimesters of pregnancy

The penis grows very quickly, reaching 2.5-3.5 cm at birth. At this time, the fetal pituitary gland begins to secrete gonadotropins LH and FSH.

From birth to pre-puberty (around 7 years old)

The penis grows slowly because the hypothalamus and pituitary gland develop slowly and testosterone levels are low.

After puberty begins

The secretion of pituitary and testicular hormones is vigorous, and the penis grows rapidly, reaching the adult level in only about 5 years, growing longer and thicker. When the sex hormone level of the elderly is significantly reduced or after surgical castration, the penis may degenerate secondary to the penis. If secondary impotence stops sexual contact for many years, it may also cause pathological degeneration. This is not a problem of use and waste as generally said, but the consequence of degenerative changes in smooth muscle fibers.

In short, the differentiation and development of the penis depends entirely on the testosterone level in the body. If testosterone secretion is insufficient during the 6th to 9th month of pregnancy, the penis will develop slower than normal and the penis will be smaller at birth.
