E coli causes infertility in men

Correspondence Address : Dr. Reproduction is an essential part of a human life and being unable to conceive marks a great impact on mind and body of both males and females. Infertility being on a rise among the couples, urogenital infections are considered to be one of the major causes. A broad range of organisms including bacteria, fungi, virus, and parasites are well documented to interfere with the reproductive function in both the sexes. They affect different sites, in males, sperm morphology, its motility and eventually its function can be affected at different levels of their development, maturation, and mobility. In females, cervical areas, tubal obstruction, and peritoneal damage are the common sites that are affected by infections, thus, interfering with human fertility.

Urinary tract infections UTIs are especially common during pregnancy. They are often caused by Escherichia coli E. When left untreated, UTIs can lead to issues with fertility as well as complications during and after pregnancy. UTIs develop when bacteria enter the urethra the thin tube that carries urine from the bladder out of the body and infect the urinary tract.

Complicated infections that aren't treated can affect reproductive organs, including the uterus. While UTIs are not usually directly blamed for fertility problems, infertility has been linked to infections of the genital and urinary tracts.

Most often, they are caused by sexually transmitted infections STIs such as chlamydia , but other infections can lead to inflammatory disease too, like prostatitis, inflammation of the prostate gland in men. They can affect the testes, epididymis the duct behind the testis , and other glands, too. These infections can result in infertility in several ways. They can damage sperm production, as well as sperm quality and function. They can also cause inflammation that blocks the reproductive tract.

In women, even though urine and reproductive fluids don't share the same passageways, bacteria can travel from the urethra to the vagina and enter the reproductive tract. Urinary tract infections are common during pregnancy.

Changes in anatomy and body chemistry contribute to this increased risk. In many cases, these infections develop with no symptoms, but they can still cause complications. Pregnant people have a higher risk of developing UTIs starting at around the sixth week of gestation. The bladder becomes fuller later in pregnancy as well, and muscle tone can decrease. This causes urine to become stagnant and can even back up into the urinary tract, increasing the risk for infection.

Urine also changes during pregnancy, becoming more concentrated, with higher levels of estrogen and glucose that can help to feed bacteria and lower your body's defenses against infection. Bacteria that commonly cause UTIs in pregnant women include:. Bacteria like group B streptococcus and Staphylococcus saprophyticus less commonly cause UTIs, but group B can cause infections in the unborn baby and be passed on to your baby during delivery.

Your doctor will usually test you for this type of bacteria before you give birth. If your UTI is diagnosed early, before it has spread to the kidneys—or even your blood—treatment with oral antibiotics, taken for about a week, is usually sufficient.

The most common types of antibiotics used to treat UTIs in pregnancy include:. If your UTI is caused by group B streptococcus, your healthcare provider should start intravenous IV, through a vein antibiotic therapy in labor to prevent sepsis , a potentially life-threatening blood infection, in your baby. Untreated urinary tract infections in pregnant women, even if they occur with no symptoms, can lead to kidney infections pyelonephritis.

Symptoms of UTIs during pregnancy may include:. The most common postpartum infections are:. UTIs are most common after a cesarean delivery C-section. Vaginal births may seem like the riskier delivery type, but mothers who have C-sections typically have a urinary catheter placed to drain their bladder for at least a small period of time. What can develop is called a catheter-associated UTI that's caused by bacteria entering the urinary tract through the catheter. For the first few months of the postpartum period, your immune system is not yet working at full capacity.

This means you could be more prone to developing infections, and your body won't be able to fight them as well as it normally would. Other challenges of the postpartum period—like adjusting to a new normal, hormonal changes, and the physical demands of caring for a newborn—make this time less than ideal for illness.

Infections that cause additional stress and discomfort could result in even more strain. There are very few diseases that would prevent you from breastfeeding, and these are mostly viral diseases like human immunodeficiency virus HIV and AIDS. You are more likely to pass illness to your infant through respiratory contact while breastfeeding than through breast milk. Urinary tract infections cannot pass to the baby through your breast milk.

However, if you become severely ill with UTI complications like pyelonephritis or urosepsis when untreated UTIs spread to your kidneys , how much milk you produce could be affected. Also, treatment with certain antibiotics or other medications could cause a concern since some drugs can cross over from your blood into your breast milk and be passed on to your baby. UTIs are generally not linked to fertility issues unless they are frequent and untreated.

UTIs are especially common during pregnancy because your ureter will expand to prepare for delivery, making it easier for bacteria to enter and cause an infection. Your risk of having UTIs remains high postpartum as well because your body is still recovering. Your healthcare team will keep a close eye on you and help treat your UTIs to make sure they don't cause complications for you and your baby.

The changes that take place in your body during pregnancy can make it easy for bacteria to enter and grow, resulting in an increased risk of developing urinary tract infections. Many of these infections develop with no symptoms at all and can lead to complications for you and your baby. Fortunately, your healthcare provider will screen for UTIs at the start of your pregnancy and before delivery. If you do develop a UTI, your medical team will treat it early so the infection doesn't spread to your kidneys.

Only certain antibiotics are safe during pregnancy, and your healthcare provider will recommend one that won't harm you or the baby. UTIs during pregnancy are caused by bacteria. The risk of developing a UTI increases in pregnancy due to changing anatomy and body chemistry.

Antibiotics are used to treat urinary tract infections in both pregnant and nonpregnant women. Which antibiotics are used may be different, though, since not all antibiotics are safe during pregnancy. UTIs are most common in the second trimester of pregnancy, when your ureter begins to dilate, or expand, in preparation for delivery. Many urinary tract infections during pregnancy develop with no symptoms. Symptoms that are present can include burning or pain during urination and urinary frequency or urgency.

You may also have fever, chills, and pain and tenderness in your lower abdomen, below the pubic bone.

Infertility is defined as trying to get pregnant with frequent, unprotected sex for at least a year with no success. Infertility results from female factors about one-third of the time and both female and male factors about one-third of the time. The cause is either unknown or a combination of male and female factors in the remaining cases. Female infertility causes can be difficult to diagnose. There are many treatments, depending on the infertility cause.

Without treatment, bacteria can spread to the uterus, ovaries, Some antibiotics cause fertility problems in men who take them for a long.

Epididymitis is a common inflammatory condition of the epididymis, a coiled tube located in the back portion of the testicle. The epididymis is responsible for transporting and storing maturing sperm. Men can have either acute or chronic versions of epididymitis. Acute epididymitis is signaled by sudden and severe symptoms. A case of epididymitis that persists for more than six weeks is considered chronic.

Bacteria in sperm hinders fertility treatment

e coli causes infertility in men

Urogenital infections are considered important factors in male infertility. In this in vitro study we have evaluated the impact of leucocytes in association with an artificial infection with Escherichia coli on the motility of human spermatozoa. Ejaculates and blood samples were obtained from healthy donors with normal semen parameters. Leucocyte subtypes were separated from blood samples by gradient centrifugation. Lymphocytes and monocytes had no effect on sperm motility.

Uropathogenic Escherichia coli UPEC -associated epididymitis is commonly diagnosed in outpatient settings. Our aim was to investigate whether pathogenic UPEC and its associated virulence factor hemolysin hlyA perturb the structural and functional integrity of both the epididymis and sperm, actions that may be responsible for the observed impairment and possibly a reduction of fertilization capabilities.

Any infection or sickness, if not treated can hamper the fertility in both men and women by damaging the reproductive parts. This is a sexually transmitted infection STI caused by bacterial infection. The symptoms include burning sensation during urination, swollen testicles, and discharges from the penis. If left untreated, Chlamydia can cause infertility in men by permanently scarring and blocking the reproductive parts and hampering the sperm production. Gonorrhea is an STI that can cause infertility in men. The symptoms include green, yellow or white discharge from the penis, dysuria, burning around the penis, swelling or pain in the testicles.

Beware of Urinary Tract Infection! It may lead to infertility

Metrics details. Although bacterial infections have been recognized as a possible cause of male infertility, the effect of bacterial infections on sperm quality and sperm DNA fragmentation remains controversial. The current study aimed to investigate the prevalence rate of bacterial infection in subfertile men and its effect on semen quality. Seminal fluid was collected from male members of infertile couples attending the andrology infertility center and a group of 35 fertile subjects as a control.

The most frequently isolated bacterium in the ejaculate of infertile men is Escherichia coli E. The aim of this chapter is to discuss the negative effects of E. The E. UPEC induces activation of polymorphonuclear leukocytes with the release of cytokines and reactive oxygen species, the latter being harmful due to their ability to induce lipid peroxidation and early sperm capacitation.

To explore the influence of Escherichia coli on the motility of human spermatozoa and its possible mechanism. Highly motile preparations of spermatozoa from normozoospermic patients were coincubated with Escherichia coli for 4 hours. At 1, 2 and 4 hours of incubation, sperm motility was determined. The factor responsible for sperm immobilization without agglutination was isolated and purified from filtrates. This report confirms the immobilization of spermatozoa by E.
