HPV in semen: evaluation of the link among infection, sperm parameters and viral genome integration
2016
Human papillomaviruses (HPVs) are agents of the most common sexually transmitted diseases. Both in men and in women, HPVs cause a variety of clinical symptoms ranging from warts to cancer. It has been shown that infection with oncogenic HPV is the major cause of development of cervical cancer in women and less frequently of penile cancers in men. HPV infects epithelial cells and can bind other cell types. Its presence in semen is widely known, but the effects on fertility and reproductive function are still controversial. Partners of women with high-grade squamous intraepithelial lesions were enrolled. From each subject seminal parameters were evaluated. HPV was detected and genotyped both …
Human papillomavirus genotype attribution in invasive cervical cancer: a retrospective cross-sectional worldwide study.
2010
Summary Background Knowledge about the distribution of human papillomavirus (HPV) genotypes in invasive cervical cancer is crucial to guide the introduction of prophylactic vaccines. We aimed to provide novel and comprehensive data about the worldwide genotype distribution in patients with invasive cervical cancer. Methods Paraffin-embedded samples of histologically confirmed cases of invasive cervical cancer were collected from 38 countries in Europe, North America, central South America, Africa, Asia, and Oceania. Inclusion criteria were a pathological confirmation of a primary invasive cervical cancer of epithelial origin in the tissue sample selected for analysis of HPV DNA, and informa…
