can male sperm cause uti in females

Urinary Tract Infections (UTIs) are a common concern that affects individuals of all genders.

However, the association between UTIs and sexual activity has prompted questions about the potential role of male sperm in causing UTIs in females. 

While UTI transmission is primarily related to bacteria, the proximity of the male and female genital areas during sexual intercourse raises inquiries.

Generally, doubt arises whether sperm itself could contribute to UTIs. 

In this article, we will learn about the causes of UTI and the interplay between sexual activity and UTI risk.

Read along to get the answer to the question, “Can Male Sperm Cause UTI in Females?”

Can male sperm cause UTI

Urinary Tract Infection (UTI) causing bacteria are absent in the sperm.

It’s essential to note that UTIs are mostly caused by E. coli bacteria in up to 90% of cases. 

These bacteria are found in as much as 95% of initial UTIs and around 84% of recurring cases related to sexual activity.

Even though sperm cells themselves don’t harbor UTI-causing bacteria, it’s important to know that the path they follow overlaps with that of urine. 

This means that if a male has a UTI, there’s a potential for bacteria to be transmitted to a woman’s vagina through sperm. 

When it comes to the question of having sexual activity while dealing with a UTI, the answer is yes. 

However, males experiencing symptoms of a UTI might encounter discomfort during ejaculation.

They might not be sexually active until they have been on antibiotics for at least 72 hours. 

Furthermore, the presence of active pathogens in the urethra and bladder remains relatively low, even after a single day of antibiotic treatment.

What can cause UTI during sex

As discussed above, sperm is not the cause of UTIs despite the increased risk posed by sex.

However, some of you may wonder what causes pathogens to enter the urinary tract.

UTIs are responsible for 8.1 million medical appointments.

Million of those cases are being linked to the elevated risks associated with sexual activity.

Other than sperm, some of the most common issues are as follows:

Birth control

Although condoms are commonly believed to prevent fluid transfer, they can actually increase UTI risks.

Condoms with spermicide can disrupt the natural balance of vaginal microbes, reducing its ability to fight bacterial infections.

Various factors play a role, like the distance between the urethra and vagina. 

However, it’s important to acknowledge that condoms and certain birth control methods might affect vaginal health.

Consult your doctor before taking any birth control pill. Some may show adverse effects.

Sexual activities

Take action during sex

While you can not control all movements during sex, you can lower risks by avoiding habits that introduce bacteria to the vagina. 

Also, transitioning from anal to vaginal penetration can lead to significant issues.

One must take action before and during sex, which can help the body’s defenses. 

If using toys, avoid sharing them, as this can also introduce bacteria.


Even if you maintain good hygiene, bacteria naturally exist near the anus. 

The physical motions of sexual activity facilitate the movement of these bacteria, leading to infections in the lower urinary tract. 

Bacteria can travel up the urinary tract, explaining why the occurrence of acute cystitis is around 0.5 to 0.7 per person-year.

While using lubrication can inhibit bacterial growth, it has also been observed to disrupt the natural balance of vaginal microbes. 

The transfer of bacteria from the woman’s anus becomes a more significant concern due to movement than that of the man’s urinary tract.

Preventing UTIs

Minimizing the risk of UTIs, whether connected to sexual activity or not, is complex. 

Prevention of UTIs centers on eliminating bacteria responsible for UTIs from the urinary and vaginal regions while promoting a balanced vaginal microbiome. 

These goals are equally important in the broader aim of preventing UTIs in everyday situations.

Some of the most important steps include the following:

  • Avoid relying on diaphragms for birth control
  • Increase your water intake to help flush out bacteria before they ascend the urinary tract
  • Consume cranberry juice
  • When wiping, go from front to back; wiping the other way can transport bacteria from the anus to the vagina
  • Refrain from using scented vaginal cleaning products that disrupt your vaginal flora

If you have faced UTI only once, there is no need to make changes in your lifestyle.

However, if UTIs recur, it indicates a susceptibility, prompting the adoption of preventive measures for ongoing management.

When to see a doctor

UTIs are generally not too serious and can go away on their own, especially if you do not notice any symptoms. 

But when symptoms do show up, they can be quite uncomfortable. 

If the infection spreads to your kidneys, it could make you feel really sick until you finish treatment. 

If you have any of these symptoms, it is a good idea to get medical help:

  • Pain in your stomach or lower back near your kidneys
  • Urine that looks cloudy, dark, or has blood in it
  • A high or low-temperature
  • Burning when you pee
  • Changes in your peeing habits, especially at night

UTIs can also happen during pregnancy, especially in the last part. 

If you’re pregnant and think you have a UTI, it is important to see a doctor as soon as you can. 

Untreated UTIs during pregnancy can be uncomfortable for you and risky for the baby.


Understanding UTIs and sexual activity and their potential causes and preventive measures are essential for maintaining urinary tract health. 

While male sperm itself does not cause UTIs.

The risks associated with sexual activity stem from the potential transmission of bacteria, particularly from the anal region. 

The use of certain birth control methods, like condoms with spermicide, can also contribute to UTI risks by disrupting the natural vaginal flora.

Preventing UTIs involves a combination of practices. 

These include maintaining proper hygiene, staying hydrated, and avoiding scented products that can harm the vaginal microbiome.

By following these steps, people can reduce UTI occurrences and keep their urinary and reproductive health in check.

Frequently Asked Questions

Can sperm cause a UTI in females?

No, sperm itself does not cause UTIs in females. UTIs are mainly caused by bacteria like E. coli. However, sexual activity can increase the risk of UTIs due to the proximity of the urethra and the potential transmission of bacteria.

Can spermicide cause UTI in males?

No, spermicide itself is not a common cause of UTIs in males. UTIs are primarily caused by bacteria. However, spermicide can help bacteria to stick to the urinary walls and promote infections.

Can a man’s sperm cause a woman to get a UTI?

While sperm itself does not cause UTIs, sexual activity can increase UTI risk due to bacteria near the urethra. Bacteria from either partner can potentially lead to UTIs in females.

Can my husband’s sperm cause UTI?

Sperm does not directly cause UTIs, but sexual activity can introduce bacteria near the urethra. Bacterial transfer during intercourse may increase UTI risk in females, including from a husband’s sperm.
