Epididymitis is an inflammation of the coiled tube (epididymis) at the back of the testicle that stores and carries sperm. Although males of any age can develop epididymitis, it occurs most frequently between ages of 20 to 39. When it develops in children, it is usually due to inflammation caused by trauma. However, some children develop it because of bacterial infections, some of which may be due to sexual abuse.
What are epididymitis causes?
The cause of epididymitis is usually a bacterial infection. The bacteria usually get to the epididymis by moving back through (retrograde) the urethra, prostate, vas deferens into the epididymis. The responsible bacteria are usually identified in about 80% of cases.
Two main groups of organisms cause most cases of epididymitis: sexually transmitted organisms and coliforms (organisms that commonly live in the intestines).
- In men younger than about 39 years of age, the causes are usually the same organisms that cause the sexually transmitted diseases of chlamydia (responsible for nearly 50%-60% of cases) and gonorrhea. The bacterial species are Chlamydia trachomatis and Neisseria gonorrhea, respectively.
- In those older than 39 years of age, the causes are usually coliforms, which are bacteria (such as Escherichia coli) that live in the intestines. These organisms also frequently cause bladder infections. Any age of men who participate in anal intercourse are more likely to get infected with E. coli or other fecal bacteria. Epididymitis is rarely caused by fungi or Mycobacterium spp.
- Chemical epididymitis (rare) is inflammation caused by the retrograde (backward) flow of urine when exercising or having sex with a full bladder.
- Amiodarone (Nexterone), a frequently used heart medication, occasionally causes inflammation of the epididymis.
- Viral infections (including mumps), mainly in the pediatric population.
Epididymitis symptoms depend on the cause. They can include:
- A tender, swollen, red or warm scrotum
- Testicle pain and tenderness, usually on one side — the pain may get worse when you have a bowel movement
- Painful urination or an urgent or frequent need to urinate
- Painful intercourse or ejaculation
- Chills and a fever
- A lump on the testicle
- Enlarged lymph nodes in the groin (inguinal nodes)
- Pain or discomfort in the lower abdomen or pelvic area
- Discharge from the penis
- Blood in the semen
Chronic epididymitis
Signs and symptoms of epididymitis usually develop over a day or two and get better with treatment. In some cases, epididymitis may not clear up completely or may recur. This is known as chronic epididymitis. Symptoms of chronic epididymitis may come on gradually. Sometimes the cause of chronic epididymitis is not identified.
Your doctor will do a physical exam, which may reveal enlarged lymph nodes in your groin and an enlarged testicle on the affected side. Your doctor also may do a rectal examination to check for prostate enlargement or tenderness and order blood and urine tests to check for infection and other abnormalities.
Other tests your doctor might order include:
Sexually transmitted infection (STI) screening. This involves obtaining a sample of discharge from your urethra. Your doctor may insert a narrow swab into the end of your penis to obtain the sample, which is then tested for the presence of bacteria or other infectious organisms. The results can be used to select the most effective antibiotic for treatment.
Ultrasound imaging. This noninvasive test uses high-frequency sound waves to create images of structures inside your body and is used to rule out conditions, such as twisting of the spermatic cord (testicular torsion) or a testicular tumor. Your doctor may use this test if your symptoms began with sudden, severe pain and other tests have not been definitive.
Nuclear scan of the testicles. Also used to rule out testicular torsion, this test involves injecting trace amounts of radioactive material into your bloodstream. Special cameras then can detect areas in your testicles that receive less blood flow, indicating torsion, or more blood flow, supporting the diagnosis of epididymitis.
The health care practitioner likely will treat the individual with antibiotics through an IV, a shot, or pills orally (to be taken for 10 days or longer). Often the treatment depends on the identity of the infecting bacteria; many physicians elect to treat with at least two different antibiotics because individuals are occasionally infected with more than one organism.
For men younger than 39 years of age, Ceftriaxone, Azithromycin, and Doxycycline are often prescribed. For men older than 39 years od age or those who participate in anal intercourse, Ciprofloxacin, Ofloxacin, Sulfamethoxazole and trimethoprim are often prescribed.
The CDC guidelines recommend that for acute epididymitis most likely caused by enteric organisms or with negative gonococcal culture or PCR nucleic acid amplification test the following:
Ofloxacin (Floxin) 300 mg orally twice a day for 10 days or levofloxacin 500 mg orally once daily for 10 days.
Guidelines change frequently; most health care practitioners who treat epididymitis are aware of these guidelines, and depending on local resistance patterns of pathogens, may change the type and duration of antibiotics to best fit the patient's condition. Pediatric treatments are best administered by pediatricians and are usually based on the weight of the patient and the infecting organism's antibiotic susceptibility. If the infection is not treated early, complications may develop that require surgery.
For patients with non-infectious causes of epididymitis (for example, chemical, inflammation) anti-inflammatory medication is often prescribed; occasionally, consultation with a urologist is recommended for additional treatments.
reasons for frequent urination means needing to urinate more often than usual. Urgent urination is a sudden, compelling urge to urinate, along with discomfort in your bladder.
A frequent need to urinate at night is called nocturia. Most people can sleep for 6 to 8 hours without having to urinate. Middle aged and older men often wake to urinate once in the early morning hours.
When frequent/urgent urination is accompanied by fever, an urgent need to urinate, and pain or discomfort in the abdomen, you may have a urinary tract infection. Other possible causes of frequent urination include:
Diabetes. Frequent urination is often an early symptom of both type 1 and type 2 diabetes as the body tries to rid itself of unused glucose through the urine.
Pregnancy. From the early weeks of pregnancy the growing uterus places pressure on the bladder, causing frequent urination.
Prostate problems. An enlarged prostate can press against the urethra (the tube that carries urine out the body) and block the flow of urine. This causes the bladder wall to become irritable. The bladder begins to contract even when it contains small amounts of urine, causing more frequent urination.
Interstitial cystitis. This condition of unknown cause is characterized by pain in the bladder and pelvic region. Often, symptoms include an urgent and/or frequent need to urinate.
Diuretic use. These medications that are used to treat high blood pressure or fluid buildup work in the kidney and flush excess fluid from the body, causing frequent urination.
Stroke or other neurological diseases. Damage to nerves that supply the bladder can lead to problems with bladder function, including frequent and sudden urges to urinate.
Less common causes include alcohol use, anxiety, caffeine, vaginitis, tumor or growth in the pelvis, bladder cancer, bladder dysfunction, and radiation therapy.In many cases, a woman can experience painful sex if there is not sufficient vaginal lubrication. When this occurs, the pain after sex can be resolved if the female becomes more relaxed, if the amount of foreplay is increased, or if the couple uses a sexual lubricant.
In some cases, a woman can experience painful intercourse if one of the following conditions is present:
- Vaginismus. This is a common condition in which there is a spasm in the vaginal muscles, mainly caused by the fear of being hurt.
- Vaginal infections. These conditions are common and include yeast infections.
- Problems with the cervix (opening to the uterus). In this case, the penis can reach the cervix at maximum penetration, so problems with the cervix (such as infections) can cause pain during deep penetration.
- Problems with the uterus. These problems may include fibroids that can cause deep intercourse pain.
- Endometriosis. A condition in which the endometrium (tissue lining the uterus) grows outside the uterus.
- Problems with the ovaries. Such problems might include cysts on the ovaries.
- Pelvic inflammatory disease. The tissues deep inside become badly inflamed and the pressure of intercourse causes deep pain.
- Ectopic pregnancy. A pregnancy in which a fertilized egg develops outside of the uterus.
- Menopause. The vaginal lining can lose its normal moisture and become dry.
- Intercourse too soon after surgery or childbirth.
- Sexually transmitted diseases. These may include genital warts, herpes sores, or other STDs.
- Injury to the vulva or vagina. These injuries may include a tear from childbirth or from a cut (episiotomy) in the perenium (area of skin between the vagina and the anus) that is made during labor.
- Emotional Pain. About 90% of intercourse-related discomfort has a physical cause, but emotions can be responsible, too.
