    Abstract:
    AIMS: We aimed to compare pelvic floor muscle (PFM) strength and sexual function in primigravid and non-pregnant women and compare PFM strength between those who exhibited and did not exhibit sexual dysfunction. METHODS: A cross-sectional observational study was conducted. The sample consisted of 154 women, including 76 primigravid and 78 non-pregnant women. The inclusion criteria were as follows: non-pregnant nulliparous women or primigravid women who were pregnant with a single foetus at least 14 weeks of gestational age and reported having sexual intercourse at least once during the last 4 weeks. The exclusion criteria were as follows: inability to contract the PFMs and prior urogynaecologic surgery. PFM strength was assessed via vaginal palpation (using the Modified Oxford Scale) and vaginal squeeze pressure (using the Peritron™ manometer). Sexual function was assessedusing the Female Sexual Function Index (FSFI) questionnaire. Sexual dysfunction was identified based on low FSFI scores.The data were analyzed using the Mann-Whiney and Spearman correlation tests. RESULTS: To discussion, primigravid women had lower FSFI scores and lower PFM strength than non-pregnant women. Women with sexual dysfunction had lower PFM strength than women without sexual dysfunction, as indicated by vaginal palpation (scores of 2 out of 5 and 4 out of 5, respectively; P < 0.001) and vaginal squeeze pressure (17.5 and 36.8 cm H2 O, P < 0.001, respectively)regardless of whether they were non-pregnant nulliparous women and primigravid. CONCLUSIONS: Primigravid women exhibited worse sexual function and lower PFM strength than non-pregnant women. Women who had higher FSFI scores demonstrated greater PFM strength.
