Introduction

In general, black raised pores on the scrotum may be caused by factors such as hyperpigmentation, sebum blockage, scrotal folliculitis, genital warts (condyloma acuminatum), or ectopic sebaceous glands. Depending on the specific situation, improvements can be achieved through general care, medication, or surgical treatment. In daily life, it is important to keep the scrotal area clean and well-ventilated, wear loose cotton clothing, and avoid spicy or irritating foods.

Generally, black raised pores on the scrotum may be caused by factors such as hyperpigmentation, sebum blockage, scrotal folliculitis, genital warts (condyloma acuminata), or ectopic sebaceous glands. Depending on the specific situation, improvements can be made through general care, medication, or surgical treatment. A detailed analysis is as follows:

1. Hyperpigmentation

The scrotal skin has many folds, and local friction or hormonal changes can lead to melanin accumulation, causing pores to appear as black raised spots. Wearing loose, breathable underwear helps reduce friction. Avoid frequent scratching and keep the area dry.

2. Sebum Blockage

Overactive sebaceous glands may produce excessive sebum, which fails to drain properly and blocks the pores; upon oxidation, these blocked pores turn black and become raised. Wash the scrotal area daily with warm water, use mild cleansers, and avoid oily or greasy foods.

3. Scrotal Folliculitis

Bacterial infection of hair follicles leads to inflammation, causing redness and swelling of the pores. In later stages, post-inflammatory pigmentation results in black raised lesions. Under medical guidance, topical antibiotics such as mupirocin ointment or fusidic acid cream may be applied, along with oral cephalexin capsules. Avoid squeezing the affected area.

4. Genital Warts (Condyloma Acuminata)

Caused by human papillomavirus (HPV) infection, the virus stimulates mucocutaneous proliferation, forming black or grayish-brown raised growths. As directed by a physician, topical treatments such as imiquimod cream or podophyllotoxin tincture may be used, along with oral transfer factor solution. Lesions can also be removed via laser surgery.

5. Ectopic Sebaceous Glands

Abnormal proliferation and clustering of sebaceous glands at scrotal pores result in black raised appearances, usually without significant discomfort. If cosmetic concerns arise, topical tretinoin cream may be used under medical supervision, or lesions may be removed via electrocautery or cryotherapy. Keep the wound clean after procedures.

Maintain cleanliness and ventilation of the scrotal area in daily life. Choose cotton, loose-fitting clothing and avoid spicy or irritating foods. If the number of raised lesions increases or is accompanied by pain or itching, seek timely medical evaluation to determine the underlying cause and receive standardized treatment—do not self-medicate, as this may delay proper diagnosis and management.

What causes black substances attached to hair on the scrotum, and what should be done about it?

Blackish deposits on scrotal hair are commonly caused by a mixture of sebum, sweat, and dirt; blood crusts after shaving; folliculitis; fungal infections; or excretions from pubic lice. Patients may choose appropriate management options such as cleansing and hygiene care, medications, or surgical intervention based on specific symptoms. Daily cleaning with warm water is recommended, along with avoiding sharing towels and practicing genital hygiene before and after sexual activity. Disinfect shaving tools before and after use, and minimize friction to reduce irritation.
