Male urethritis is generally divided into gonococcal urethritis and non-gonococcal urethritis, which is one of the more common sexually transmitted diseases in men. Gonococcal urethritis is caused by gonococcal infection and is characterized by specific purulent discharge from the urethra, mostly in young adults, and is currently the most prevalent sexually transmitted disease in China. The most common pathogens of non-gonococcal urethritis are Chlamydia trachomatis and Ureaplasma urealyticum, a few caused by Trichomonas vaginalis or Candida albicans, common symptoms are urethral stinging, urinary urgency, painful urination, clear watery discharge or purulent discharge from the urethra, clinical symptoms are relatively mild, patients often turn chronic due to mild symptoms without timely treatment. The actual UTI is a very good way to get the most out of your life. The actual UTI is a very good way to get the most out of the UTI. The actual Urethritis is usually the following parts: 1. chronic urethritis: manifested by repeated symptoms of frequent urination, painful urination, urethral discomfort, incomplete urination, etc., which often persists clinically; 2. chronic prostatitis: in addition to urethral irritation symptoms, there may be perineal pain and discomfort, lumbar swelling, etc., or accompanied by mental symptoms; 3. chronic vesicular adenitis: mostly occurs in combination with chronic prostatitis, which can manifest itself as transient hematemesis or persistent pain. Chronic epididymitis or orchitis: manifested as scrotal pain and discomfort, thickening and hardening of the epididymis, epididymal nodules, epididymal cysts or testicular atrophy, etc. It is important to note that the sequelae of UTI in men can infect their spouses through sexual contact, which can lead to UTI, cervicitis, endometritis, tubitis or pelvic inflammatory disease in women, which may cause infertility. UTI sequelae can affect male fertility through the following mechanisms: 1. destroy sperm production: sperm are produced by the spermatogenic cells of the testicular varicoceles, chronic orchitis or testicular atrophy can lead to the destruction of the morphology and function of spermatogenic cells, resulting in sperm production disorders; 2. affect sperm development and reduce sperm vitality: sperm are produced by the testes and then transported to the epididymis for further development and maturation and energy acquisition, chronic epididymitis Chronic epididymitis can lead to fibrosis of the epididymis, resulting in changes in the internal environment of the epididymis, which in turn affects the development and maturation of sperm and reduces sperm vitality; 3. Affects the transport of sperm in the vas deferens: the sequelae of urethritis can lead to narrowing or blockage of the oviduct, ejaculatory duct or epididymal duct, resulting in obstruction of sperm transport in the duct, thus causing infertility. If a male friend inadvertently develops UTI, he should be detected early, treated as early as possible, and take active treatment to avoid the occurrence of UTI sequelae. It is recommended that patients choose to go to a specialist at a regular hospital to receive treatment, preferably with their sexual partner at the same time. The UTI can be prevented by having unclean sex.
