Genital bleeding can be a deeply troubling and worrying symptom.
While many things can cause genital bleeding, you may want to consider the possibility of a sexually transmitted infection (STD).
Some STIs can lead to bleeding, whether it’s between periods, during or after intercourse, or from other parts of the body. Understanding sexually transmitted infections can cause this symptom and recognizing the importance of early diagnosis and treatment is vital to maintaining sexual health.
This blog aims to shed light on which STDs can cause bleeding, the mechanisms behind this symptom and the importance of seeking medical advice if you experience any unusual bleeding. By raising awareness, we hope to encourage preventive health measures and reduce the stigma associated with STIs.

Common STDs that cause genital bleeding
Some common STDs can cause bleeding, especially from the genitals.
You should note that while both men and women can experience genital bleeding in response to a sexually transmitted disease, women are more likely to experience vaginal bleeding as a symptom.
Gonorrhea
Gonorrheaalso known as “the clap”, is an STD caused by bacteria Neisseria gonorrhoeae. It can be transmitted through vaginal, anal, oral sex and sharing sex toys. Symptoms may include a burning sensation when urinating, unusual discharge and in women, abnormal vaginal bleeding. If left untreated, it can lead to serious health problems such as pelvic inflammatory disease (PID), abdominal pain, infertility and pregnancy complications.
In women: Gonorrhea can cause inflammation in the reproductive tract, leading to symptoms such as painful urination and unusual vaginal discharge. Bleeding may occur between periods or after intercourse due to the infection causing irritation and inflammation of the cervix.
In men: Men with gonorrhea may experience painful urination and discharge from the penis. In some cases, the inflammation can cause bleeding, which can lead to blood in the urine (haematuria) or bleeding from the urethra.
Chlamydia
Chlamydia is a common sexually transmitted infection caused by the bacterium Chlamydia trachomatis. It can infect various areas of the body, including the penis, vagina, anus and throat. Often referred to as a “silent” STD, many people with chlamydia have no symptoms. When symptoms do occur, they may include painful urination, unusual discharge, and other symptoms.
In women: When symptoms occur in women, they may include bleeding between periods and after intercourse. This bleeding is usually due to inflammation and infection of the cervix.
In men: While chlamydia is often asymptomatic in men as well, it can cause symptoms such as painful urination and penile discharge. In some cases, it can also lead to bleeding, particularly if the infection causes inflammation in the urethra.
Mycoplasma
Mycoplasma is a type of bacteria that can infect the genitals, urinary tract, rectum, and lungs. Mycoplasma genitalium is a sexually transmitted infection that often goes unnoticed due to its asymptomatic nature. When symptoms do occur, they may include unusual discharge, painful urination, and bleeding after intercourse or between periods in women.
In women: Mycoplasma infections can lead to symptoms such as abnormal vaginal discharge, pain in the lower pelvic area, and pain during intercourse. Bleeding may occur after intercourse or between menstrual periods due to inflammation of the cervix and other parts of the reproductive system.
In men: Men with mycoplasma infections may experience painful urination, urethral discharge, and penile irritation or pain. The inflammation caused by the infection can sometimes lead to bleeding from the urethra.
Ureaplasma
Ureaplasma is a bacterium that naturally lives in the respiratory, urinary and reproductive systems. It can be transmitted through sexual contact, but often occurs on its own as a result of an imbalance in the natural flora of the vagina. Symptoms may include pain during urination, unusual discharge, and inflammation of the urethra.
In women: Ureaplasma can cause inflammation of the urethra, pain during urination, and unusual, watery vaginal discharge. Bleeding may occur due to irritation and inflammation around the vagina.
In men: Men with ureaplasma infections may experience inflammation of the urethra, pain during urination, and unusual discharge from the penis. This inflammation can sometimes cause bleeding from the urethra.
Herpes
Herpes it is caused by the herpes simplex virus (HSV) and can lead to painful blisters around the genital area. During a herpes outbreak, these blisters burst and form sores, which may bleed, especially if you pick them or the skin around them becomes inflamed. Eventually, these wounds peel and heal.
Human Papilloma Virus (HPV)
HPV is a common viral infection that can lead to genital warts and, in some cases, cervical cancer.
Certain high-risk strains of HPV can cause changes in the cells of the cervix, leading to abnormal bleeding, particularly after intercourse. Regular screening and early detection are crucial to managing HPV-related complications.
Final thoughts
Understanding the various STIs that can cause bleeding, whether from the genitals or other parts of the body, is crucial for early detection and effective treatment. Bleeding can be a distressing symptom, but recognizing its potential connection to STDs can prompt early medical intervention and prevent further complications.
