What causes black spots on genitals?

The genitals are the most private part of the human body. Usually, we don’t pay special attention to them, but we may accidentally find black spots on them. Experts say that for female friends, it may be caused by aging, so there is no need to worry too much. For male friends, it may be melanin deposition, but it may also be glansitis. In this case, we must pay special attention and must actively seek treatment.

1. What are the black spots on the genitals?

Black spots on the genitals are caused by glansitis, which is mostly caused by friction from underwear, trauma, or local irritation from soap or detergents. It manifests as edema, erythema, exudation, erosion, secondary infection with purulent secretions, easy formation of ulcers, and spontaneous pain. It can be treated with 3% boric acid solution or 0.05% berberine solution for wet compresses.

2. Causes of Penitis

(1) Non-infectious factors

Including local trauma, friction, contraceptives, soap and detergents and other irritants, local manifestations may be edema erythema, erosion, exudation and even bleeding. If secondary bacterial infection occurs, it may become purulent and form an ulcer. The patient has obvious pain and difficulty in movement. Clinically, it is called acute superficial glansitis.

(2) Candida infection

Candida is a conditionally pathogenic fungus, so candidal glansitis often occurs secondary to diabetes, senile wasting diseases, and after large-scale antibiotic or hormone treatment. It can also be primary, mostly transmitted from the spouse's candidal vaginitis. The glans and coronal sulcus may have light red erosions and thin-walled abscesses, but Candida is often not found locally, which may be caused by local allergic reaction caused by Candida.

(3) Amoeba infection

Most patients first have balanoposthitis, which causes the local loss of normal barrier function, and then is caused by intestinal amoebiasis. Local erosion, ulceration, and tissue necrosis are obvious, and amoeba can be found in direct smears of secretions.

(4) Trichomonas infection

Most cases are caused by the spouse suffering from vaginal trichomoniasis. The symptoms are mild, mainly manifested as erythematous papules and small blisters on the glans. The borders are clear and the scope gradually expands. Patients often feel itchy. Trichomonas can be found in the secretions. In addition, there are some cases of glansitis whose causes are unclear, but the foreskin is too long and the smegma irritation is often related to the occurrence of glansitis. Therefore, men should also wash their lower body frequently, keep the local area clean and avoid irritation.
