Abstract

Background: Psychological stress and its two stress response systems, the hypothalamic-pituitary-adrenal (HPA) axis and the autonomic nervous system (ANS), are closely related to psychogenic erectile dysfunction (pED). However, the analyses of perceived stress and stress systems in pED patients need to be more in-depth, especially the interactions between them. Methods: Our study included 75 patients with pEDs and 75 healthy men. The International Index of Erectile Function-5 (IIEF-5) and the 10-item Perceived Stress Scale (PSS-10) were used for assessing the severity of ED and perceived stress. All participants collected saliva samples on three consecutive days at eight specific times with strict reference to the time of morning awakening for measuring cortisol parameters and wore electrocardiography for 24 h to derive heart rate variability (HRV). Results: The PSS-10 scores of pED patients were significantly higher than the control group (p<0.001). Although PSS-10 and IIEF-5 scores were negatively correlated in pED patients, there was no statistical significance between them (r=−0.049, p=0.677). Compared with the control group, the HRV parameters of pED patients were significantly increased in LF/HF ratio (p=0.014) but significantly decreased in LF, HF, and pNN50 (p<0.001). However, the two groups had no statistically significant differences in cortisol variables (all p>0.05). The interaction between sympathovagal modulation (HF, rMSSD) and cortisol awakening response (CAR AUCi) explained significantly greater variance in perceived stress than either stress system alone. Higher parasympathetic activity combined with a higher cortisol awakening response was associated with greater perceived stress. Conclusion: Our results suggested that the interrelation between ANS and HPA axis activity might enhance our comprehension of how stress affected the physical and mental health of pED patients.

Overview

CoChat Summary

TL;DR

In 75 men with psychogenic erectile dysfunction (pED) and 75 healthy controls, pED patients reported greater perceived stress and showed autonomic imbalance (lower LF, HF, pNN50; higher LF/HF) but no significant differences in salivary cortisol measures. In pED patients, interactions between parasympathetic HRV indices (HF, rMSSD) and cortisol awakening response (CAR AUCi) explained additional variance in perceived stress beyond either system alone.

Key findings

  • pED patients had significantly higher PSS-10 scores (17.44 ± 4.75 vs. 13.97 ± 6.08, p < 0.001) and lower IIEF-5 scores (8.40 ± 2.34 vs. 23.12 ± 0.97, p < 0.001); PSS-10 and IIEF-5 were negatively but not significantly correlated in pED patients (r = −0.049, p = 0.677).
  • HRV differed significantly: pED patients had lower LF (median 670.00 vs. 1893.00 ms², p < 0.001), lower HF (622.00 vs. 3845.00 ms², p < 0.001), lower pNN50 (16.50 vs. 18.50 ms, p < 0.001), and higher LF/HF ratio (0.66 vs. 0.60, p = 0.014).
  • No cortisol variable differed significantly between groups (all p > 0.05).
  • In pED patients, HF × CAR AUCi and rMSSD × CAR AUCi interactions accounted for an additional 6.1% and 5.9% of variance in perceived stress; higher HF or rMSSD combined with higher CAR AUCi was associated with greater perceived stress (HF: k = 3.333, p = 0.009; rMSSD: k = 3.065, p = 0.009). In controls, only pNN50 was associated with perceived stress in the singular HRV model, and no significant interactions were found.

Methods

  • Case-control study at a urology male clinic from March 2016 to August 2022; 75 pED patients and 75 healthy men completed the study (ages 20–49, mean 31.9 ± 7.1 years).
  • Participants completed the IIEF-5 and PSS-10, collected saliva eight times per day for three consecutive weekdays for cortisol parameters, and wore 24-h electrocardiography for HRV.
  • Analyses used independent-sample t-tests, Kruskal-Wallis tests, chi-square/Fisher’s exact tests, and hierarchical linear regression comparing singular HRV or cortisol models with inter-relation models including two-way interactions; simple slope analyses interpreted significant interactions.

Limitations

  • The authors state that comparisons with other studies were difficult due to the lack of research on HPA axis activity and perceived stress in ED, and that their use of hierarchical regression, interaction, and simple slope analyses may have increased chances of finding meaningful associations.
  • The authors state that more stress measures and additional autonomic/HPA measures (e.g., salivary alpha-amylase, pre-ejection period, cortisone, dehydroepiandrosterone) are needed, and that the cross-sectional design cannot determine causal direction.
  • Evident from the text: the study was single-center, used a modest sample size, and recruited only men, which may limit generalizability; the authors also note a smaller sample size as a possible reason for not detecting subtle HPA axis changes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-11-14, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-14 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
