Testicular infections from STIs, also known as epididymo-orchitis, refer to inflammation or infection of the testicles and epididymis due to sexually transmitted infections (STIs) such as gonorrhea or chlamydia. This condition can lead to pain, swelling, and discomfort in the scrotum and may require medical treatment to prevent complications.

Epididymo-orchitis is a condition where the epididymis (a coiled tube at the back of the testicle that stores and carries sperm) and the testicle become inflamed or infected. This can occur as a result of untreated or inadequately treated STIs such as gonorrhea or chlamydia, which can ascend the reproductive tract and cause infection in the testicles.

Symptoms of testicular infections from STIs may include severe pain and tenderness in the testicles, swelling, redness, warmth in the scrotum, fever, and discharge from the penis. It is essential to seek medical attention promptly if any of these symptoms occur, as untreated epididymo-orchitis can lead to complications such as abscess formation, infertility, or chronic pain.

Diagnosis typically involves a physical examination, medical history review, and tests such as urine analysis, blood tests, and swabs from the urethra or discharge to identify the causative STI. Treatment usually consists of antibiotics to clear the infection, pain management, and rest. In some cases, hospitalization may be necessary, especially if complications arise.

Prevention of testicular infections from STIs includes practicing safe sex by using condoms correctly and consistently, getting tested regularly for STIs, and seeking prompt treatment if any symptoms of an STI or testicular infection arise. It is crucial to communicate openly with sexual partners about STI status and sexual health to reduce the risk of transmission.
