© 2021 Elsevier B.V.Objective: To document the deterioration in pelvic organ support occurring throughout all trimesters during the first pregnancy of women with no known risk factors. Secondarily to make a comprehensive review in order to verify the current findings and methodologies of similar studies in the literature. Study Design: In this prospective study, forty-one primigravid women with a singleton pregnancy were recruited during their first trimester. During follow-up pelvic organ support changes were documented by using Pelvic Organ Prolapse Quantification (POP-Q) system. Additionally, pelvic floor muscle strength examination, by modified Oxford scoring (MOS), and symptom assessment by Pelvic Floor Distress Inventory-Short Form (PFDI-20) were performed at three time points: first (T1), second (T2), and third trimester (T3) (n = 33). The Wilcoxon test was performed to test the significance of pairwise differences. Spearman correlation coefficient was estimated to determine the linear association of the findings. Results: Both distal and proximal anterior and posterior vaginal walls (Points Aa, Ba, Ap and Bp) with cervix (C) descended towards the hymen, throughout first pregnancy with a significant caudal shift on progressing from T2 to T3 (p ≤ 0.017). Posterior fornix (Point D) made a non-significant cranial shift (p = 0.527). The genital hiatus, perineal body and total vaginal length increased significantly (p ≤ 0.001). No significant difference in MOS was observed throughout pregnancy. The scores of PFDI-20 with all its domains worsened significantly during pregnancy, especially in T3 (p ≤ 0.011). Moderate correlations were observed between posterior vaginal descent and anorectal symptoms (rho 0.427, p < 0.05), and between the changes in genital hiatus and prolapse symptoms (rho 0.406, p < 0.05). Conclusion: A significant descent both in all compartments of vaginal wall and perineum with an increase in total vaginal length, was observed together with an associated pelvic floor dysfunction throughout the first pregnancy of women.
