Androgens, such as testosterone, have an antinociceptive effect based on animal and adult studies. However, because androgens may exert different physiological effects during puberty, it is not clear whether the antinociceptive effect would also be found in adolescents. Thus, this study examined the relationships between testosterone levels and experimental pain sensitivity in healthy young adolescent girls. In addition, the relationships between experimental pain sensitivity and other androgens, including dehydroepiandrosterone (DHEA), dehydroepiandrosterone-sulfate (DHEA-S), dihydrotestosterone, and androstenedione, were explored, and the role of puberty in moderating these relationships was tested. Forty-five healthy girls (11.91 ± 1.35 years) completed comprehensive psychophysical assessments of heat, cold, and pressure pain thresholds, heat and cold pain intensity ratings, temporal summation, heat- and pressure-conditioned pain modulation, offset analgesia, and cold pain tolerance. Blood samples were collected to analyze sex hormone levels. Participants also completed the Pubertal Developmental Scale. Correlations and regression models examined the associations between androgens and experimental pain sensitivity, and whether pubertal stage moderated these relationships. Overall, no significant associations were found between levels of testosterone, DHEA, DHEA-S, dihydrotestosterone, or androstenedione and experimental pain sensitivity, nor were these associations moderated by pubertal stage. Only DHEA-S levels were related to cold pain threshold and tolerance, and pubertal stage moderated the relationship between DHEA-S and cold pain tolerance, which was significant only in the late (r = 0.453, P = 0.027) but not early-mid puberty group. The results of this study suggest that androgens may have a minimal effect on experimental pain sensitivity in healthy young adolescent girls.
基于动物和成人研究,雄激素(如睾酮)具有抗伤害感受作用。然而,由于雄激素在青春期可能发挥不同的生理作用,目前尚不清楚抗伤害感受作用在青少年中是否也会出现。因此,本研究调查了健康年轻青春期女孩的睾酮水平与实验性疼痛敏感性之间的关系。此外,还探讨了实验性疼痛敏感性与其他雄激素(包括脱氢表雄酮(DHEA)、硫酸脱氢表雄酮(DHEA-S)、双氢睾酮和雄烯二酮)之间的关系,并测试了青春期在调节这些关系中的作用。45名健康女孩(11.91±1.35岁)完成了对热、冷和压力疼痛阈值、热和冷疼痛强度评分、时间总和、热和压力条件性疼痛调制、抵消镇痛和冷痛耐受性的全面心理物理学评估。采集血样以分析性激素水平。参与者还完成了青春期发育量表。相关性和回归模型研究了雄激素与实验性疼痛敏感性之间的关联,以及青春期阶段是否调节了这些关系。总体而言,未发现睾酮、DHEA、DHEA-S、双氢睾酮或雄烯二酮水平与实验性疼痛敏感性之间存在显著关联,这些关联也未受青春期阶段的调节。仅DHEA-S水平与冷痛阈值和耐受性相关,青春期阶段调节了DHEA-S与冷痛耐受性之间的关系,这仅在青春期后期(r = 0.453,P = 0.027)有显著意义,而在青春期早中期组则无显著意义。本研究结果表明,雄激素对健康年轻青春期女孩的实验性疼痛敏感性可能影响极小。
