Neonatal male circumcision is a painful skin-breaking procedure that may affect infant physiological and behavioral stress responses as well as mother-infant interaction. Due to the plasticity of the developing nociceptive system, neonatal pain might carry long-term consequences on adult behavior. In this study, we examined whether infant male circumcision is associated with long-term psychological effects on adult socio-affective processing.
We recruited 408 men circumcised within the first month of life and 211 non-circumcised men and measured socio-affective behaviors and stress via a battery of validated psychometric scales.
Early-circumcised men reported lower attachment security and lower emotional stability while no differences in empathy or trust were found. Early circumcision was also associated with stronger sexual drive and less restricted socio-sexuality along with higher perceived stress and sensation seeking.
This is a cross-sectional study relying on self-reported measures from a US population.
Our findings resonate with the existing literature suggesting links between altered emotional processing in circumcised men and neonatal stress. Consistent with longitudinal studies on infant attachment, early circumcision might have an impact on adult socio-affective traits or behavior.
新生儿男性包皮环切术是一种会造成皮肤破损的疼痛手术，可能会影响婴儿的生理和行为应激反应以及母婴互动。由于发育中的伤害感受系统具有可塑性，新生儿疼痛可能会对成人行为产生长期影响。在本研究中，我们调查了婴儿男性包皮环切术是否与对成人社会情感加工的长期心理影响有关。
我们招募了408名在出生后第一个月内接受包皮环切术的男性和211名未接受包皮环切术的男性，并通过一系列经过验证的心理测量量表测量社会情感行为和应激情况。
早期接受包皮环切术的男性报告的依恋安全性较低，情绪稳定性也较低，而在同理心或信任方面未发现差异。早期包皮环切术还与更强的性欲、更少受限的社会性行为以及更高的感知应激和感觉寻求有关。
这是一项横断面研究，依赖于来自美国人群的自我报告测量。
我们的研究结果与现有文献一致，表明接受包皮环切术的男性情绪加工改变与新生儿应激之间存在联系。与关于婴儿依恋的纵向研究一致，早期包皮环切术可能会对成人的社会情感特征或行为产生影响。
