What is the cause of the black spots on the glans?

If there are black spots on the glans, you should pay attention and go to the hospital for a andrological examination in time. After the andrological disease is confirmed, systematic treatment measures should be taken. Some patients will not only have black spots, but may also develop ulcers or be extremely weak. These are very common manifestations of glans inflammation. After suffering from it, you must first take some anti-inflammatory treatments.

Balanitis is related to many factors, which can be divided into infectious factors and non-infectious factors. Under normal circumstances, a large number of bacteria, yeasts and spirochetes can parasitize in the foreskin sac, and when local or systemic resistance is weakened, these microorganisms can become pathogenic pathogens. Balanitis is mainly caused by bacteria, such as Escherichia coli, Staphylococcus, Streptococcus, followed by Candida, Trichomonas, Mycoplasma, Chlamydia, Gonorrhea, etc. can also cause balanitis.

Non-infectious factors include stimulation from urine, alkaline substances (such as detergents) and foreign substances (such as condoms); friction and trauma; excessive foreskin and insufficient cleaning leading to accumulation of smegma, which can cause damage to the glans foreskin mucosa and aggravate infection by various pathogens.

1. Acute superficial galactitis

It is mainly seen in young and middle-aged people with active sexual life, and the infecting bacteria are usually the same as the strains of bacterial vaginosis of their sexual partners. At the beginning of the disease, the local skin is flushed, and the glans penis feels burning and itchy. In the acute stage, the foreskin is turned back to reveal edematous erythema, erosion, exudate and bleeding on the glans penis. In severe cases, blisters may appear. If secondary infection occurs, ulcers may form, covered with purulent exudate, and local pain and tenderness are obvious. Some patients may have mild systemic symptoms, such as fatigue and weakness. In the chronic stage, only the inner plate of the foreskin and the coronal sulcus have flaky flushing, or cracks like broken porcelain.

2. Annular ulcerative glansitis

It may be the early mucosal damage of Reites disease, or it may be related to the long-term stimulation of smegma. The clinical manifestation is erythema on the glans penis, which gradually expands and becomes ring-shaped or multi-ring-shaped, and may later form shallow ulcers. The main feature of this disease is one or more round lesions on the glans penis, with a red erosive surface in the middle and a white narrow band on the edge, forming a ring. If secondary infection occurs, the symptoms may be aggravated and lose their ring-shaped characteristics.

3. Candidal balanitis

Caused by Candida infection, most commonly Candida albicans. Clinical manifestations include erythema of the foreskin and glans penis, smooth surface, slight desquamation around, scattered papules or small pustules around, and slowly expanding to the surrounding area. In the acute stage, edema, erythema, erosion, and exudate may occur. In severe cases, it may affect the penis body, scrotum, inner thigh and groin. It is mostly caused by sexual contact infection, but it can also be secondary to diabetes, wasting diseases, and long-term and large-scale antibiotic or hormone treatment.
