This study seeks to determine if total vaginal length (TVL) or genital hiatus (GH) impact sexual activity and function.
Heterosexual women >or= 40 years were recruited from urogynecology and gynecology offices. TVL and GH were assessed using the Pelvic Organ Prolapse Quantification exam. Women completed the Female Sexual Function Index (FSFI) and were dichotomized into either normal function (FSFI total > 26) or sexual dysfunction (FSFI <or= 26).
Five hundred five women were enrolled; 333 (67%) reported sexual activity. While sexually active women had longer vaginas than women who were not active (9.1 cm +/- 1.2 versus 8.9 cm +/- 1.3, p = 0.04), significance was explained by age differences. GH measurements did not differ (3.2 cm +/- 1.1 versus 3.1 cm +/- 1.1, p = 0.58). In sexually active women, TVL was weakly correlated with FSFI total score, but GH was not. TVL and GH did not differ between women with normal FSFI scores and those with sexual dysfunction.
Vaginal size did not affect sexual activity or function.
本研究旨在确定阴道总长度（TVL）或生殖裂孔（GH）是否会影响性活动和性功能。
从泌尿妇科和妇科诊所招募年龄≥40岁的异性恋女性。使用盆腔器官脱垂定量检查评估TVL和GH。女性完成女性性功能指数（FSFI），并被分为功能正常组（FSFI总分>26）或性功能障碍组（FSFI≤26）。
共纳入505名女性；333名（67%）报告有性活动。有性活动的女性阴道长度长于无性活动的女性（9.1厘米±1.2 与8.9厘米±1.3，p = 0.04），但这种差异可由年龄差异解释。GH测量值无差异（3.2厘米±1.1与3.1厘米±1.1，p = 0.58）。在有性活动的女性中，TVL与FSFI总分呈弱相关，但GH与FSFI总分无相关性。FSFI评分正常的女性与性功能障碍的女性之间，TVL和GH无差异。
阴道大小不影响性活动或性功能。
