The human papillomavirus (HPV) is a common sexually transmitted infection, typically acquired after the first sexual activity. Most HPV infections are asymptomatic and temporary. Recurrent infections with high-risk HPV strains can lead to various cancers later in life. HPV infections are also significantly associated with reproductive function abnormalities, including male infertility and increased risk of miscarriage and premature labor. Gardnerella vaginalis (GV), an anaerobic bacterium, can contribute to bacterial vaginosis (BV) and reduced fertility in women. More research is needed to understand the exact mechanisms of how GV and HPV cause infertility.
A prevalent sexually transmitted infection, the human papillomavirus (HPV) is typically obtained just after the first sexual activity. The majority of HPV infections are asymptomatic and temporary. Cervical, anal, penile, vaginal, vulvar, and oropharyngeal cancers can occur due to recurrent infections with high-risk (hr)-HPV strains, generally decades later. Infections with HPV are significantly associated with reproductive function abnormal-ities. Per recent research, HPV infections may result in male infertility by reducing sperm motility. The hr-HPV infection was a risk factor for miscarriage, and the indiscriminate HPV genotype increased the probability of premature labor unexpectedly. Women's endometrial trophoblastic cell implantation is decreased by HPV. Gardnerella vaginalis (GV), an anaerobic bacterium that is a component of the natural vaginal flora, can be associated with bacterial vaginosis (BV) when it starts to overgrow and emerge as the dominant species. Reduced Lactobacillus species abundance and GV are linked to female infertility. Data from in vitro studies suggests that sialidase produced by GV may facilitate the entry and growth of papilloma and other sexually transmitted vi-ruses. Also, based on some studies conducted in the past, it can be said that GV and BV are associated with the development of uterine cancer. However, there is still not enough information about the exact mechanism of GV and HPV in causing infertility, which requires more research.
