Discordance Between Spermatozoa Detection and Self-Reported Semen Exposure

In Brief An analysis of data from a prospective study of 1257 high-risk women revealed 7 predictors of discordance between self-reported lack of recent exposure to semen and detection of spermatozoa on Gram stain, suggesting that inaccuracies in the reporting of sexual behaviors cannot be assumed to be distributed randomly. Analysis of 1257 high-risk women found several predictors of discordance between self reports and an objective marker of semen exposure, suggesting inaccuracies in reporting sexual behaviors are not randomly distributed.
