HPV Impact on Fertility: Examining the Connection
In the realm of sexual health, Human Papillomavirus (HPV) stands as the most common sexually transmitted infection (STI). This group of viruses, transmitted through skin-to-skin contact, can have significant implications for both male and female fertility.
### Impact on Male Fertility
HPV infection in men has been linked to decreased sperm quality, including reduced sperm count, motility, and normal morphology. High-risk HPV types are more commonly found in semen samples from infertile men, correlating with impaired sperm viability and increased DNA fragmentation.
HPV infection can also lead to elevated antisperm antibodies, further reducing sperm motility and contributing to infertility. The rate of HPV infection is higher in infertile men compared to fertile men, and HPV sperm infection has been associated with worse sperm parameters. Moreover, the presence of HPV in sperm has been linked to increased rates of early miscarriage.
### Impact on Female Fertility
While the link between HPV and female fertility is less well-established, there are concerns about HPV vaccination potentially being associated with premature ovarian failure (early menopause) in some women, a condition that causes infertility by stopping normal ovarian function before age 40. However, this is related specifically to the vaccine and remains a subject of ongoing investigation.
HPV infection in women, particularly with high-risk types, is linked to adverse pregnancy outcomes, including miscarriage and pregnancy loss. The viral infection can interfere with cervical and placental function, potentially contributing to these risks.
### HPV Vaccination and Fertility
Contrary to some misconceptions, there is no credible evidence that the HPV vaccine causes infertility. Instead, by preventing HPV infections that lead to cervical and other cancers, the vaccine may help preserve fertility. Pregnant women are advised to avoid the HPV vaccine due to limited safety data during pregnancy, but the vaccine is generally safe with mild side effects and no established causal link to serious adverse fertility outcomes.
### Implications for Reproductive Health
This nuanced effect of HPV on fertility underscores the importance of screening and prevention measures in both sexes to minimize reproductive risks. Vaccination may help improve fertility and pregnancy outcomes, even in people who already have HPV. Regular Pap smears help screen for HPV, including strains that may increase the risk of cervical precancer and cancer.
A 2018 systematic review found that the presence of HPV in the male partner negatively affects pregnancy rates and increases the risk of miscarriage. HPV in men, women, or both can increase the risk of pregnancy loss. Of people will have an HPV infection at some point in their life, many without realizing.
One 2016 study found that HPV-positive women were six times less likely than HPV-negative women to become pregnant after using intrauterine insemination (IUI). The presence of HPV in sperm negatively affects pregnancy outcomes in men. The American College of Obstetricians and Gynecologists (ACOG) list scarring and blockages in the fallopian tubes as potential risk factors for infertility.
In light of these findings, it is crucial to prioritise HPV prevention and screening, not only for the prevention of cervical cancer but also to safeguard reproductive health. Making sure partners are vaccinated can help prevent HPV transmission. HPV vaccines provide protection against several types of HPV and genital warts for both men and women. By taking these preventative measures, we can help ensure a healthier future for individuals and families alike.
