Effect of the Menstrual Cycle and Hormonal Contraceptives on Human Papillomavirus

(Obstet Gynecol 2010;116:67–75)

OBJECTIVE:  To estimate the effect of the menstrual cycle and oral contraceptive pill (OCP) use on the prevalence, incidence, and persistence of human papillomavirus(HPV).

METHODS:  A longitudinal study was conducted among 2,065 women aged 18–29 years. The women returned a self-collected cervicovaginal sample and filled out a questionnaire. A total of 1,812 women participated at all three time points, month 0, month 6, and month 12.

RESULTS:  Low- and high-risk HPV prevalence at study entry was 8.9% and 11.8%, respectively. The annual incidence of low-risk HPV infections was 12.5% and the persistence was 2.0%. For high-risk HPV, the incidence and persistence was 12.1% and 4.5%, respectively. These results did not differ between OCP users and nonusers. A significant relationship between high-risk HPV detection and the timing of sampling was found when OCP users and nonusers were analyzed separately. In the second half of the menstrual cycle, high-risk HPV detection decreased in nonusers ( P _.007) and increased in OCP users ( P_.021). When women used OCPs continuously, high-risk HPV detection returned to the level of the first half of the menstrual cycle.

CONCLUSION:  High-risk HPV detection was significantly influenced by sample timing in the menstrual cycle when analyzed separately for OCP users and women with a natural menstrual cycle. This may have implications in the future, when high-risk HPV detection may become a primary screening tool in cervical cancer prevention.
