Human papillomavirus, or HPV, is a common virus that affect both men and women.
According to research, up to 80% of people will be infected with at least one type of HPV at some time. Genital contact during sex is the main way to get HPV.
Because the disease is very common, scientists suggest all teen boys and girls and adults younger than 26 years old to have HPV vaccine.
HPV is linked to lower pregnancy rates and reduced semen quality, but how HPV vaccine influences fertility is unknown.
In a recent study, researchers from Boston University answer this question. They found that PHV vaccine can actually improve fertility in some women.
The finding is published in Paediatric and Perinatal Epidemiology.
The researchers found that for women with a history of sexually transmitted infections (STIs), HPV vaccine was linked to better fertility. For other men and women, there was little association.
Previous findings showed that STIs are linked to lower fertility, and the current study shows that when STI women get HPV vaccine, their chance of being pregnant is as high as unvaccinated women with no STI history.
Researchers suggest that the findings should reassure people who don’t want to get HPV vaccine because of fertility concerns, because no harmful effects of HPV vaccine on fertility.
The study analyzed data of 3483 women and 1022 men aged between 21 and 45. All people were trying to conceive. The research team followed couples for 12 months or until pregnancy.
At the beginning of the study, 33.9 percent of women had been vaccinated against HPV, compared to 5.2 percent of men.
The researchers suggest that parents should help their teen children get HPV vaccine without worrying about its effect on fertility.
The vaccine can help prevent cancers of the cervix, vulva, vagina, anus, penis, and throat. The side effects include mild fever (10%), moderate fever (1.6%), and itching at the injection site (3.3%).
