Premature Ejaculation Symptoms Are Associated with Sexual Excitability: Empirical Support for the Hyperarousability Model

Abstract

Premature ejaculation (PE) is a common sexual complaint among men, but its etiology is poorly understood. Previous studies on the dual control model of sexuality has revealed that propensities for sexual excitation and inhibition can contribute to sexual dysfunctions, but few studies have included a measure of premature ejaculation. We sought to explore whether PE is associated with sexual excitation or inhibition. We applied structural equation models to data from a large population-based sample of Finnish adult men. The analyses supported a four-factor solution for the sexual inhibition/sexual excitation short-form scale. The clearest result was that increased symptoms of PE were associated with a greater propensity for sexual excitation (β = 151, p < 001, n = 2953). Importantly, this excitation was intrapersonal, as opposed to stemming from social activities. The results imply that men with PE may have stronger and more rapid reactions to sexual stimuli, which in turn may lead to ejaculating earlier than desired.

Topological differences of striato‐thalamo‐cortical circuit in functional brain network between premature ejaculation patients with and without depression

“…Both structural and functional damage to thalamus highlighted a deficiency in its ejaculatory inhibition control (M. Gao et al., 2022; S. Gao et al., 2023). The higher propensity for sexual excitation and stronger reaction to sexual stimuli were found in PE patients (Ventus & Jern, 2021). Therefore, we also speculated subsequently elevated sexual inhibitory demand in the mechanism of rapid ejaculation, which is presented by enhanced nodal topological properties.…”

Associations between Self-Reported Anatomical Characteristics of the Penis, Age and Sexual Dysfunction in Men

“…The 5-item diagnostic tool Checklist for Early Ejaculation Symptoms (CHEES), which was developed from three earlier ejaculation diagnostic tools and has improved validity (69), was used to measure the ejaculation control of the participants. This measure has been proven to perform well in differentiating men with and without PE in a Western population sample (AUC = 0.98) (69) and to have good internal reliability of .760 (70). It has not previously been used with Chinese samples.…”
