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.
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.
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 H O, P < 0.001, respectively)regardless of whether they were non-pregnant nulliparous women and primigravid.
Primigravid women exhibited worse sexual function and lower PFM strength than non-pregnant women. Women who had higher FSFI scores demonstrated greater PFM strength.
我们旨在比较初产妇和未孕女性的盆底肌肉（PFM）力量及性功能，并比较有和没有性功能障碍的女性之间的PFM力量。
进行了一项横断面观察性研究。样本包括154名女性，其中76名初产妇和78名未孕女性。纳入标准如下：未孕未育女性或孕周至少14周且怀有单胎、并报告在过去4周内至少有一次性交的初产妇。排除标准如下：无法收缩盆底肌肉以及既往有泌尿妇科手术史。通过阴道触诊（使用改良牛津量表）和阴道挤压压力（使用Peritron™压力计）评估PFM力量。使用女性性功能指数（FSFI）问卷评估性功能。根据FSFI低得分确定性功能障碍。数据采用Mann-Whiney和Spearman相关性检验进行分析。
讨论如下，初产妇的FSFI得分和PFM力量低于未孕女性。无论是否为未孕未育女性和初产妇，有性功能障碍的女性其PFM力量均低于没有性功能障碍的女性，阴道触诊显示（分别为5分制中的2分和4分；P<0.001），阴道挤压压力也显示（分别为17.5和36.8cmH₂O，P<0.001）。
初产妇的性功能和PFM力量比未孕女性差。FSFI得分较高的女性显示出更强的PFM力量。
