Abstract: Some research has found relationships between personality dimensions and ejaculate quality, but this research has limitations. In the current study, we investigated the relationships between six major personality dimensions and several ejaculate parameters. Forty-five fertile men provided two masturbatory ejaculates and completed a measure of major personality dimensions. Agreeableness was the only personality dimension consistently associated with ejaculate parameters after controlling for participant age, Body Mass Index, and abstinence duration. In short, disagreeable men produced higher-quality ejaculates. The current study adds to previous evidence documenting that psychological attributes—such as disagreeableness—are associated with ejaculate quality. We highlight limitations of the current research and identify directions for future research.
