Concordance of HPV status observed: 79% K = 0.28, p value < 0.001.
Note: Concordance of status corresponds to the percentage of couples in which both partners were HPV negative or both were positive, independently of risk group or HPV type. Concurrent infection corresponds to the percentage of couples for which both partners were positive independently of the risk group or HPV type. Number in bold indicates couples with concurrent infection (34).
^a When infection is present in both men and women and there is at least one HPV genotype in common.
^b Sample taken from the combination of epitheleal cells from the middle third of the scrotum and penile shaft, the balano-preputial lamina and the urinary meatus.
