Using quantitative sensory testing and a validated questionnaire, we investigated the role of pudendal nerve integrity in sexual function among women.
Participants completed the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ). Vibratory and pressure thresholds were measured at the S2 dermatome reflecting pudendal nerve distribution.
A total of 56 women enrolled; 29 (51.8%) were asymptomatic and 27 (48.2%) had 1 or more forms of female sexual dysfunction (total sexual dysfunction) including: desire disorder 16.1%, arousal disorder 26.8%, orgasmic disorder 25%, and pain disorder 12.5%. Age, parity, menopausal status, and body mass index were similar between groups. PISQ scores were lower in symptomatic subjects compared with controls (P < .001). Decreased tactile sensation was found at the clitoris for women with total sexual dysfunction, desire disorder, and arousal disorder. Women with arousal disorder also had decreased tactile sensation at the perineum.
Pudendal nerve integrity may play a role in female sexual dysfunction.
通过定量感觉测试和一份经过验证的问卷，我们研究了阴部神经完整性在女性性功能中的作用。
参与者完成了盆腔器官脱垂/尿失禁性功能问卷（PISQ）。在反映阴部神经分布的S2皮节测量振动和压力阈值。
共有56名女性参与研究；29名（51.8%）无症状，27名（48.2%）有1种或多种形式的女性性功能障碍（总体性功能障碍），包括：性欲障碍16.1%、性唤起障碍26.8%、性高潮障碍25%和性交疼痛障碍12.5%。两组之间的年龄、产次、绝经状态和体重指数相似。有症状的受试者的PISQ评分低于对照组（P < 0.001）。患有总体性功能障碍、性欲障碍和性唤起障碍的女性，其阴蒂的触觉感觉降低。患有性唤起障碍的女性在会阴处的触觉感觉也降低。
阴部神经完整性可能在女性性功能障碍中起作用。
