We investigated the relationship between objective psychologic test data and endocrine parameters as well as ejaculate characteristics in 117 husbands in barren couples. Data analysis suggests that test scores indicating high self-confidence, extraversion, and social assertiveness correspond negatively with male fertility parameters. Our results show that levels of gonadotropins and sex steroids, as well as accessory gland functions, are not randomly related to personality attitudes in these patients, but support the idea that psychologic factors are relevant in male infertility.
