HPV

The sperm of men infected with high-risk genotypes of the human papillomavirus (HPV) suffers more damage from oxidative stress and has a weaker immune response, which can lead to reduced fertility. This is one of the conclusions of a study published in the journal Frontiers in Cellular and Infection Microbiology. The research compared the semen of 20 adults infected with high-risk genotypes, seven infected with low-risk genotypes, and 43 adults without infections.

A study in South Korea followed more than 160,000 women for more than eight years and concluded that infection with different strains of human papillomavirus is associated with a fourfold increase in the relative risk of dying from cardiovascular causes. According to the authors, "it could be that the virus causes inflammation in the blood vessels, contributing to blockage and damage to the arteries". The findings are published in the European Heart Journal.
