Animal studies have shown androgens, especially testosterone, may have an analgesic effect on nociceptive behavior. However, it is unclear if this effect is present in humans. This review and meta-analysis aim to summarize and synthesize the role of androgens on experimental pain sensitivity in humans. Studies were included if they examined the (1) relationships between androgens and experimental pain sensitivity, (2) group differences in androgen or pain levels, and (3) the effect of androgen interventions on experimental pain sensitivity. After a comprehensive search, 31 papers were identified. When possible, meta-analyses were performed. Most studies examined the impact of testosterone on experimental pain, and only a few studies focused on other androgens, such as dehydroepiandrosterone and dehydroepiandrosterone sulfate. Overall, the current data do not support the effect of androgens on experimental pain sensitivity in adult men and women with or without chronic pain. In addition, meta-analyses of Pearson correlations did not find relationships between testosterone levels and pain ratings of heat stimulus (3 studies, n = 93, Z correlation coefficient = -0.43, confidence intervals [-1.50, 0.64]) or electrical pain thresholds (4 studies, n = 147, Z correlation coefficient = 0.24, confidence intervals [-0.10, 0.58]). Moreover, contradicting results were found in intervention studies that increased or decreased testosterone levels. Thus, it is suggested that the role of testosterone on experimental pain sensitivity may be minor, even though there is a wide heterogeneity between studies. Future studies should examine the impact of other androgens and the interaction between testosterone and other hormones on experimental pain sensitivity.
动物研究表明,雄激素,尤其是睾酮,可能对伤害感受行为具有镇痛作用。然而,这种作用在人类中是否存在尚不清楚。本综述和荟萃分析旨在总结和综合雄激素在人类实验性疼痛敏感性中的作用。如果研究考察了以下方面,则纳入研究:(1)雄激素与实验性疼痛敏感性之间的关系;(2)雄激素或疼痛水平的组间差异;(3)雄激素干预对实验性疼痛敏感性的影响。经过全面检索,共识别出31篇论文。在可能的情况下,进行了荟萃分析。大多数研究考察了睾酮对实验性疼痛的影响,只有少数研究关注其他雄激素,如脱氢表雄酮和硫酸脱氢表雄酮。总体而言,目前的数据不支持雄激素对患有或未患有慢性疼痛的成年男性和女性的实验性疼痛敏感性有影响。此外,对皮尔逊相关性的荟萃分析未发现睾酮水平与热刺激疼痛评分(3项研究,n = 93,Z相关系数 = -0.43,置信区间[-1.50, 0.64])或电痛阈值(4项研究,n = 147,Z相关系数 = 0.24,置信区间[-0.10, 0.58])之间存在关系。此外,在增加或降低睾酮水平的干预研究中发现了相互矛盾的结果。因此,尽管研究之间存在很大的异质性,但提示睾酮对实验性疼痛敏感性的作用可能较小。未来的研究应考察其他雄激素的影响以及睾酮与其他激素之间的相互作用对实验性疼痛敏感性的影响。
