A critical appraisal of the value of vaginal acid phosphatase determination for the estimation of post-coital time.

Abstract

A careful literature review of the use of vaginal fluid acid phosphatase levels as a means to estimate post-coital time disclosed several inconsistencies. In this study, acid phosphatase levels were determined in vaginal fluid samples obtained from 200 women whose post-coital time was known. No statistical significance (at 5% probability levels) was found when vaginal acid phosphatase levels were correlated with post-coital time.
