Human papillomavirus type distribution among heterosexual couples.

Objective: To gain a better understanding of human papillomavirus (HPV) transmission dynamics between sexual partners, HPV-type-specific concordance was investigated.

Methods: Twenty-nine couples were enrolled in this cross-sectional study. Mean age was 30.

Test-retest reliability and predictors of unreliable reporting for a sexual behavior questionnaire for U.S. men.

Accurate knowledge about human sexual behaviors is important for increasing our understanding of human sexuality; however, there have been few studies assessing the reliability of sexual behavior questionnaires designed for community samples of adult men. A test-retest reliability study was conducted on a questionnaire completed by 334 men who had been recruited in Tucson, Arizona. Reliability coefficients and refusal rates were calculated for 39 non-sexual and sexual behavior questionnaire items.

Reliability of sample collection and laboratory testing for HPV detection in men.

Analysis of male HPV infection is hindered frequently by the lack of consistency in collection methods and sample adequacy for detection of HPV with molecular methods. Presented here are the reliability of sample collection of male anogenital skin exfoliated cells, as well as reliability of PCR-based HPV detection method and genotyping analysis. Concordance of HPV test for paired collected samples from different anatomical sites was determined.
