Methods: Data on 2D:4D and testosterone from two samples were collected: (1) 43 men attending an infertility clinic, and (2) 51 men drawn from the general population without regard to fertility. Results: In sample (1) there were negative associations between 2D:4D and testicular function, and men with lower 2D:4D in their right compared to left hand had higher testosterone levels than men with higher 2D:4D in their right compared to left hand. Sample (2) showed no significant associations between 2D:4D or side differences in 2E>:4D and testosterone. Conclusion: Adult levels of testosterone may be related to aspects of 2D:4D in samples which contain men with compromised testicular function, but not in men from normative samples. Associations between 2D:4D and fertility-associated traits probably arise from early organisational effects of testosterone rather than from activational effects of current testosterone.展开更多
研究人类第二根手指长度(second finger length,2D)与第四根手指长度(fourth fingerlength,4D)的比率(digit ratio of 2D and 4D,2D:4D)与运动能力遗传存在相关性。结果显示,2D:4D在出生前就已经定型,其与母亲子宫睾酮浓度及成年后睾酮...研究人类第二根手指长度(second finger length,2D)与第四根手指长度(fourth fingerlength,4D)的比率(digit ratio of 2D and 4D,2D:4D)与运动能力遗传存在相关性。结果显示,2D:4D在出生前就已经定型,其与母亲子宫睾酮浓度及成年后睾酮浓度存在着负相关。睾酮浓度会影响大脑右半球和空间视觉能力的发育,从而影响运动能力。展开更多
