Background: Personality disorders may influence sexual behaviours and sexual dysfunction.

Aim: Our main objective was to analyse the influence of personality disorders (PDs) in patients with erectile dysfunction (ED) of psychological origin that fail to respond to andrological treatment with Phosphodiesterase-5 inhibitors (IPDE5), assessing whether there are differences in sexual behaviours and response to psychosexual treatment.

Methods: The research is designed as an ex post facto retrospective study with two groups. A control group of 23 men with ED without personality disorders and a group of 51 men with both ED and PDs.

Results: In the case sample, 34.30% of the participants presented more than one personality disorder. No significant differences were found in sexual behaviours except for heteromasturbation (men without PDs masturbated their partners more to satisfy them than men with PDs), and men with PDs considered themselves less premature ejaculators than the control group. Finally, 82.14% of the control group did well with psychosexual therapy compared to 53.85% of the PDs group.

Conclusion: Psychosexual treatment of ED has a worse outcome if the men also have PDs. Strengths and Limitations: from a clinical standpoint, it is important to assess the presence of personality disorders in men with ED and to implement psychosexual strategies to improve the response to treatment in these cases. Confirmation of the results with a much larger sample becomes necessary.

背景：

人格障碍可能会影响性行为和性功能障碍。

目的：

我们的主要目标是分析人格障碍（PD）对心理原因引起的勃起功能障碍（ED）患者的影响，这些患者的磷酸二酯酶-5抑制剂治疗无效，并评估是否存在在性行为及心理性治疗反应方面的差异。

方法：

这项研究设计为一种事后回顾性研究，包含两组。一组是23名没有人格障碍的ED男性对照组，另一组是有51名同时患有ED和PD男性的实验组。

结果：

在样本中，34.30%的参与者表现出超过一种的人格障碍。除了异性自慰（无PD的男性比有PD的男性更频繁地为满足伴侣而自慰）以外，并未发现性行为方面的显著差异。患有PD的男性认为自己比对照组更少早泄。最后，82.14%的对照组在心理性治疗中表现出良好的反应，而PD组这一比例为53.85%。

结论：

如果男性同时伴有人格障碍，则其ED的心理性治疗效果较差。优势与局限：从临床角度来看，评估ED男性的存在的人格障碍非常重要，并在这些情况下实施心理性策略以改善对治疗的反应是必要的。需要通过更大规模样本来确认研究结果。
