手指医学名称
?说到手指长度,不少民间传闻说手指长、鼻子高、身高高的男生丁丁会更长,但在这里要负责任的告诉大家,丁丁大小跟这些都没有关系,而只跟人种、遗传等因素相关。
但是,著名医学杂志 Andrology 曾发表过一篇文章说到:手指长度虽然跟丁丁的大小无关,但是却跟蛋蛋的大小息息相关!
让我们来看看原文是如何描述的:We found that the patients with a higher digit ratio may be more likely to have smaller testes compared to those with a lower digit ratio. These results are similar to ones from previous studies of the relationship between digit ratio and fertility. Auger & Eustache (2011) showed that digit ratios are signi?cantly and negatively associated with testicular volume and male reproductive health. Other investigations demonstrated that men with low digit ratios have high sperm counts and large family sizes (Manning et al., 1998). Moreover, Wood et al. (2003) asserted that testicular sperm retrieval in azoospermic men is more successful in men with low digit ratios than in ones with high digit ratios.
这项研究纳入了 172 名年龄在 20~69 岁之间男性,量取了他们的右手第 2 指(示指)与第 4 指(环指)的长度,并取手指比例,同时也测量了他们睾丸的体积。结果表明,手指比例越小,睾丸体积越大。也就是说,假设环指为单位 1,那么示指越长的人,睾丸越小。
手指医学名称示指这又可以分为两种情况:示指比环指短:两者长度相差越大,睾丸越大;示指比环指长:两者长度相差越大,睾丸越小。
这项研究还对比了年龄、体重、睾酮浓度等,发现手指比是预测所有(右、左和总)睾丸体积的独立因素。睾丸的体积在一定程度上反映了生精能力,其体积大小可以作为男性生育能力的指标。而这项研究可以说对研究男性健康有着极(bing)其(wu)深(luan)远(yong)的意义。看到这里,各位男同胞们是不是已经默默地伸出了你们的右手呢
