3 Common Habits in Men That May Increase Their Partner's Risk of Cervical Cancer

Cervical cancer remains one of the most preventable forms of cancer, yet it continues to affect hundreds of thousands of women worldwide each year. The overwhelming majority of cervical cancer cases are linked to persistent infection with high-risk types of the human papillomavirus (HPV). Although HPV is extremely common and often clears on its own, certain behaviors can increase the likelihood of persistent infection, raising the risk of cervical precancer and cancer over time.

While discussions about cervical cancer often focus on women, men also play an important role in HPV transmission and prevention. Healthy habits, vaccination, and safe sexual practices can help protect both partners.

Below are three behaviors that may increase a partner's risk of HPV infection and, in some circumstances, contribute to a higher risk of cervical cancer.

1. Having Multiple Sexual Partners Without Protection

One of the strongest risk factors for acquiring HPV is exposure through sexual contact.

A man who has:

• Multiple current sexual partners
• A history of numerous sexual partners
• Unprotected sexual activity

is statistically more likely to acquire and transmit HPV.

HPV is spread primarily through intimate skin-to-skin sexual contact, including vaginal, anal, and oral sex. Most sexually active people—both men and women—will be exposed to HPV at some point in their lives.

It's important to remember:

• HPV infection is common and often causes no symptoms.
• A person can carry and transmit HPV without knowing it.
• Infection does not necessarily imply infidelity or recent sexual activity, as the virus may remain dormant for years.

Using condoms can reduce the risk of HPV transmission, although they do not provide complete protection because HPV can infect skin not covered by a condom.

2. Not Receiving the HPV Vaccine

HPV vaccination is one of the most effective ways to prevent infection with the HPV types responsible for most cervical cancers.

Vaccination is recommended for:

• Adolescents before becoming sexually active
• Young adults who have not previously been vaccinated
• Some adults up to age 45 after discussing potential benefits with their healthcare provider

When more boys and men receive the HPV vaccine, it helps reduce the circulation of high-risk HPV strains in the community, providing protection for both themselves and their partners.

Vaccination also lowers the risk of several other HPV-related cancers, including cancers of the:

• Throat (oropharynx)
• Penis
• Anus

3. Smoking

Smoking affects far more than the lungs.

Research has shown that smoking may:

• Weaken the immune system
• Make it harder for the body to clear HPV infections
• Increase exposure to carcinogenic chemicals
• Contribute to DNA damage

Women who smoke have a higher risk of persistent HPV infection and cervical cancer. Smoking by a male partner does not directly cause cervical cancer, but secondhand smoke may also have adverse health effects, and smoking is associated with other behaviors that can increase HPV transmission.

Quitting smoking benefits the health of both partners and the entire household.

Other Important Risk Factors for Cervical Cancer

Although the behaviors above can influence HPV transmission, several additional factors also affect cervical cancer risk.

These include:

• Persistent infection with high-risk HPV types (the primary cause)
• Not participating in regular cervical screening
• A weakened immune system (such as from HIV infection or immunosuppressive medications)
• Long-term smoking
• Early onset of sexual activity
• Having multiple sexual partners (for either partner)
• Long-term use of certain hormonal contraceptives (associated with a small increase in risk that decreases after stopping)
• Lack of HPV vaccination

How Couples Can Help Prevent Cervical Cancer Together

Preventing cervical cancer is a shared responsibility.

Healthy steps include:

• Receiving the HPV vaccine if eligible
• Practicing safer sex, including condom use
• Limiting exposure to multiple sexual partners
• Avoiding tobacco use
• Encouraging regular medical checkups
• Supporting healthy lifestyle habits that strengthen the immune system

For women, routine cervical screening remains one of the most effective preventive measures.

The Importance of Cervical Screening

Even women who have received the HPV vaccine still need regular cervical cancer screening, because current vaccines do not protect against every cancer-causing HPV type.

Depending on age and national guidelines, screening may include:

• A Pap test (Pap smear) to detect abnormal cervical cells
• An HPV test to identify high-risk HPV infections
• Or a combination of both

Early detection allows precancerous changes to be treated before cancer develops.

Common Misconceptions

Several myths continue to circulate online.

Myth: Only women need to worry about HPV.

Fact: HPV affects both men and women and can cause several different cancers.

Myth: HPV always causes symptoms.

Fact: Most HPV infections cause no symptoms at all.

Myth: Having HPV means someone has been unfaithful.

Fact: HPV can remain dormant for many years before being detected, making it impossible in many cases to determine when transmission occurred.

Myth: The HPV vaccine is only for girls.

Fact: Vaccination is recommended for both boys and girls because it protects individuals and helps reduce transmission within the population.

When Should You Seek Medical Advice?

Women should consult a healthcare provider if they experience:

• Bleeding after sexual intercourse
• Bleeding between menstrual periods
• Bleeding after menopause
• Persistent pelvic pain
• Pain during intercourse
• Unusual vaginal discharge

These symptoms do not necessarily indicate cervical cancer, but they should always be evaluated promptly.

The Bottom Line

Cervical cancer is largely preventable, and persistent infection with high-risk HPV is its primary cause. Certain behaviors in male partners—such as having multiple sexual partners without protection, remaining unvaccinated against HPV, and smoking—may increase the likelihood of HPV transmission or persistence, which can contribute to cervical cancer risk over time.

Fortunately, couples can take meaningful steps to reduce that risk through HPV vaccination, safer sexual practices, smoking cessation, and regular cervical screening. Because cervical cancer often develops slowly over many years, prevention and early detection remain the most effective tools for protecting women's health.
