Genetic quality may be expressed through many traits simultaneously, and this would suggest a phenotype-wide fitness factor. In humans, intelligence has been positively associated with several potential indicators of genetic quality, including ejaculate quality. We conducted a conceptual replication of one such study by investigating the relationship between intelligence (assessed by the Raven Advanced Progressive Matrices Test–Short Form) and ejaculate quality (indexed by sperm count, sperm concentration, and sperm motility) in a sample of 41 men (ages ranging 18 to 33 years; M = 23.33; SD = 3.60). By self-report, participants had not had a vasectomy, and had never sought infertility treatment. We controlled for several covariates known to affect ejaculate quality (e.g., abstinence duration before providing an ejaculate) and found no statistically significant relationship between intelligence and ejaculate quality; our findings, therefore, do not match those of Arden, Gottfredson, Miller et al. or those of previous studies. We discuss limitations of this study and the general research area and highlight the need for future research in this area, especially the need for larger data sets to address questions around phenotypic quality and ejaculate quality.

没有证据表明智力和射精质量之间存在关系。

遗传质量可以同时通过许多性状表达,这表明存在表型范围内的适应性因素。在人类中,智力与遗传质量的几个潜在指标呈正相关,包括射精质量。我们对一项此类研究进行了概念性重复,通过调查 41 名男性样本中的智力(通过 Raven 高级渐进矩阵测试简表进行评估)和射精质量(以精子数量、精子浓度和精子活力为索引)之间的关系(年龄范围 18 至 33 岁;M = 23.33;SD = 3.60)。根据自我报告,参与者没有进行输精管结扎术,也从未寻求不孕不育治疗。我们控制了几个已知影响射精质量的协变量(例如,射精前的禁欲持续时间),发现智力和射精质量之间没有统计学上的显着关系。因此,我们的研究结果与 Arden、Gottfredson、Miller 等人的研究结果并不相符。或以前的研究。我们讨论了这项研究和一般研究领域的局限性,并强调了该领域未来研究的必要性,特别是需要更大的数据集来解决有关表型质量和射精质量的问题。
