Erectile dysfunction has adverse implications for both men and their female partners. The International Index of Erectile Function (IIEF) is a widely used self-report measure. It was unclear whether scores generated by women on behalf of men are comparable to self-reports, and how IIEF scores are associated with satisfaction for both sexes in both sexual and nonsexual realms (e.g., mental health).
To examine sex differences in IIEF-5 scores generated by both sexes, and to examine associations of IIEF-5 scores with satisfaction aspects (sexual, life, own mental health, partnership) and with women's vaginal orgasm consistency (VOC).
A representative sample of Czechs (787 men and 720 women not from the same couple) aged 35-65 years completed the IIEF-5, LiSat satisfaction scale items, and provided penile-vaginal intercourse (PVI) frequency, and for women, VOC.
Correlations between satisfaction measures and IIEF-5 scores separately by sex. To examine sex differences: t-test for IIEF-5 score and tests for difference of a correlation for associations of IIEF-5 with satisfaction measures. Analysis of covariance examined the association of IIEF-5 scores and VOC. Multiple regression calculated satisfaction scores from IIEF-5, PVI frequency, age, and for women: VOC.
IIEF-5 scores generated by men and by women were similar, and similarly positively correlated with all satisfaction measures (r: 0.41-0.45 with sexual, 0.23-0.34 with other; all P < 0.001). IIEF-5 correlated positively with VOC. Multivariate analyses indicated IIEF-5 scores; PVI frequency (and for women, VOC) make independent contributions to aspects of satisfaction for both sexes.
In this representative sample, women generated IIEF-5 scores similar to men-generated scores. For both sexes, greater IIEF-5 scores and PVI frequency (plus VOC for women) are associated with greater sexual and nonsexual satisfaction. Better erectile function was associated with greater VOC. Greater support for optimizing specifically PVI function, frequency, and quality is warranted.
勃起功能障碍对男性及其女性伴侣都有不良影响。国际勃起功能指数（IIEF）是一种广泛使用的自我报告测量工具。目前尚不清楚女性代表男性生成的分数是否与自我报告相似，以及 IIEF 分数如何与两性在性和非性领域（例如心理健康）的满意度相关。
检查两性生成的 IIEF-5 分数的性别差异，并检查 IIEF-5 分数与满意度方面（性、生活、自身心理健康、伴侣关系）的关联，以及与女性阴道高潮一致性（VOC）的关联。
年龄在 35-65 岁的捷克代表性样本（787 名男性和 720 名非夫妻关系的女性）完成了 IIEF-5、LiSat 满意度量表项目，并提供了阴茎阴道交（PVI）频率，以及女性的 VOC。
分别按性别对满意度测量与 IIEF-5 分数之间的相关性进行分析。为了检查性别差异：对 IIEF-5 分数进行 t 检验，对与满意度测量相关的相关性差异进行检验。协方差分析用于检查 IIEF-5 分数与 VOC 的关联。多元回归从 IIEF-5、PVI 频率、年龄以及女性的 VOC 中计算满意度分数。
男性和女性生成的 IIEF-5 分数相似，与所有满意度测量均呈正相关（r：0.41-0.45 与性相关，0.23-0.34 与其他相关；均 P <0.001）。IIEF-5 与 VOC 呈正相关。多元分析表明，IIEF-5 分数、PVI 频率（以及女性的 VOC）对两性的满意度方面有独立的贡献。
在这个代表性样本中，女性生成的 IIEF-5 分数与男性生成的分数相似。对于两性来说，更高的 IIEF-5 分数和 PVI 频率（加上女性的 VOC）与更高的性和非性满意度相关。更好的勃起功能与更高的 VOC 相关。更有必要优化具体的 PVI 功能、频率和质量。
