Aims Anogenital distance (AGD) has been proposed as a marker of the prenatal hormonal milieu and potential environmental insults. The measures of the Pelvic Organ Prolapse‐Questionnaire (POP‐Q) system is being widely used in the evaluation of the perineum in women with POP pathologies. Genital hiatus (GH) and perineal body (PB) lengths have been related to both prolapse incidence and recurrence and for pessary treatment failure. The use of AGD in female human studies is now emerging and its comparability with other anthropometric measurements could be relevant. The aim of the study was to compare AGD and POP‐Q system in adult females. Methods The study included 155 pregnant women in the first stage of labor. Perineal measurements were performed on women in the lithotomy position: AGD from the anus to the clitoris (AGD AC ); AGD from the anus to the fourchette (AGD AF ); GH from the external urethral meatus to the posterior midline hymen, and length of the PB from the posterior midline hymen to the mid‐anal opening. Coefficients of variations (CV) were calculated. Intraclass correlation coefficients (ICC) and Bland‐Altman graphs were used to compare both set of measurements. Results CV were below 15% for AGD AC and GH + PB, though higher for AGD AF and PB (20% and 17%, respectively). ICCs for each pair of measurements were above 80%, (excellent agreement between methods). Concordance between measurements was confirmed by Bland‐Altman graphs. Conclusions Comparable measurements were obtained using AGDs and POP‐Q system. Further studies are needed to explore clinical and epidemiological implications of these findings.
