What causes bumps on a man's genitals?

Lumps appearing on the male genitalia may be caused by normal hair follicle and sebaceous gland hyperplasia, balanitis, genital herpes, genital warts, syphilis, or other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analysis is as follows:

1. Normal Hair Follicle and Sebaceous Gland Hyperplasia

The skin of the male genital organs, like other areas of the body, contains abundant hair follicles and sebaceous glands. If there are changes in the body's androgen levels, the hair follicles and sebaceous glands may undergo hyperplasia or enlargement, manifesting as small bumps. This condition is typically a normal physiological variation and does not require special treatment.

2. Balanitis

This may be related to infections caused by pathogens such as bacteria or fungi. Local inflammation can lead to symptoms including redness, papules, and blisters on the glans penis. Men are advised to use clotrimazole cream, miconazole nitrate cream, or similar medications as prescribed by a doctor.

3. Genital Herpes

This is primarily a sexually transmitted infection caused by invasion of the herpes simplex virus. The virus may cause symptoms such as blisters, ulcers, and pain in the genital area. Men are advised to take antiviral medications such as valacyclovir hydrochloride tablets, acyclovir tablets, or aspirin enteric-coated tablets as directed by a physician.

4. Genital Warts

This condition is mainly caused by human papillomavirus (HPV) infection, typically presenting as wart-like growths around the genital area, which may appear cauliflower-like, papillary, or cockscomb-shaped. Men should use medications such as imiquimod cream, podophyllotoxin cream, or recombinant human interferon α2b injection under medical supervision to manage the condition.

5. Syphilis

This is generally a sexually transmitted disease caused by Treponema pallidum. Patients may exhibit different symptoms at various stages of syphilis. In primary syphilis, a hard chancre may appear on the genital area, presenting as one or more painless ulcers. Men should strictly follow medical advice and use medications such as procaine penicillin for injection, benzathine penicillin for injection, or potassium furazlocillin benzylpenicillin for injection to alleviate symptoms.

In daily life, men are advised to wash the genital area daily with warm water, avoid using overly irritating cleansing products, maintain local cleanliness and dryness, and practice safe sexual habits, all of which are beneficial for recovery.
