Penis ulcers

Penis ulcers

Penis ulcers are genital ulcers that could occur anywhere throughout the groin area damaging the scrotum to as deep as to touch the testicles, vulva, penile shaft, perianal region, penile glans, or anus.

Genital ulcers are most commonly caused by infectious agents (fungal infections, secondary bacterial infections, or sexually transmitted diseases such as genital herpes, syphilis, or chancroid).

Before learning penis ulcers, we better be finding the definition of an ulcer. An ulcer is an open sore of the skin, eyes, or mucous membrane, often caused by an initial abrasion and generally maintained by an inflammation and/or an infection.

By the definition of ulcers, we can come to an understanding of what penis ulcer is or what it would look like. The opening of skin into a hole or damaged skin texture on the penile body due to inflammation or infection is what compounds penis ulcers.

Penis ulcers also include foreskin blisters. The ulcers in the male urethra are categorized to be penis ulcers.

The itchy and painful ulceration on the penis is what elaborately defines penis ulcers.

Symptoms like painful urination and abnormal discharge from the penis occur. Men may feel testicular pain, too.

During penis ulcers, forget about sexual intercourse, it could even be hard to erect the penile body. The erection needs the penis to become big with all the stretch and strain of the penile skin, flesh, and muscles.

An ulcer-affected penis may not be able to handle the stretch of its body due to sexual stimulations or erection.

Causes of Penis ulcers

The causes of penis ulcers are majorly certain types of sexually transmitted diseases or infections. Let's look into those certain types of STDs or STIs that could or would cause penis ulcers.

Before going into which STDs or STIs could cause penis ulcers, we may first learn what is a sexually transmitted disease or infection.

Sexually Transmitted Diseases

STDs or STIs are diseases or infections transmitted through sexual contact, developed by shared bacteria, viruses, or parasites. A disease or an infection related to the sexual transmission could be born then and there itself during sex between two uninfected persons who are subjected to earlier sex with other persons. 

In another way, the infected person may share a virus or parasite with an uninfected person during a sexual course. It is more of an uncertain infection, most of the STDs require a medical diagnosis.

Genital herpes

Penis ulcers could be caused by genital herpes, a common sexually transmitted infection marked by genital pain and sores.

Pain, itching, and small sores are the first showers that result in ulcers and scabs. After initial infection, genital herpes lies inactive in the body. Symptoms may happen again after years.


Penis ulcers could be caused by chancroid, a sexually transmitted bacterial infection that causes painful lumps and ulcers in the groin. It's most common in Africa, Asia, and Latin America.

Granuloma inguinale

Granuloma inguinale is a bacterial disease caused by Klebsiella granulomatis characterized by genital ulcers.


A bacterial infection is usually spread by sexual contact that starts as painless sores which show up as genital sores or genital ulcers.


Chronic penis ulcers are observed to be the first manifestation of HIV infection. 

HIV is the first segment in HIV/AIDS also called Human Immunodeficiency Virus(HIV), Acquired Immunodeficiency Syndrome(AIDS) is considered a familiar repulsive monster in mankind born on its own. HIV causes AIDS and gets involved with the body's ability to fight infections.

The virus can be transmitted through contact with infected blood, semen or vaginal fluids, blood products (unclean needles or unscreened blood), and penile intercourse in unprotected vaginal, anal or oral sex.

Other than sexually transmitted diseases, other conditions could cause severe ulcers on the penile body.

Penile cancer

Penile cancer is one of the serious penile conditions that are outcomes as genital ulcers and the impact is deep-rooted from the blood cells and tissues. The damage of the blood cells corresponding to the skin of the penis is penile cancer. This cancer can be congenital or a rare contagious cancer disease under sexual transmission diseases or infection.


Balanitis is a skin disorder that could show up as skin opening or ulcer groping on the foreskin or head of the penis due to infection or mishandling. Inflammation is the main reason to get balanitis on the penis. Inflammation is the general body's biological response to damaged tissues and cells, issues caused due to aging of tissues, etc.


Scabies causes tiny blisters or sores on the skin that are extremely itchy, especially at night. The uncontrollable or the involuntary act of itching the penis could make holes or openings on the foreskin leading to ulcers.
