在很快乐得从冰冷的泳池中出来以后,乔治•科斯坦萨的阴茎就不幸得缩水,但是对于大多数男人而言,生殖器官的长度与周长问题并不是一个可以玩笑的事情。现在,一项新的研究可能会缓解这种担心,可以约定最准确的阴茎大小测量值。
    
许多早期的研究依靠自我报告,这总是产生不可靠的结果。“人们往往会高估自己。” 任职于伦敦南部和莫兹利NHS信托基金会的心理医生David Veale说。所以当他和他的团队着手解决对阴茎的比例得分时,他们决定从遵循标准化的测量过程的门诊医生中汇编数据。
    
目前已发表于British Journal of Urology International的新的研究中,综合了从以前的17篇学术论文中,包括来自世界各地的总数为15521人测量的数据。这些数据使研究人员计算出平均值和整个人类模拟阴茎尺寸的估计分布。“这还只是让我觉得:有如此多的男人对自己阴茎大小的问题的不安全感和关注度。我们的确需要关于此问题的很好的数据。”任职于印第安纳大学伯明顿分校的行为科学家Debra Herbenick说,她并没有参加此项研究。
    
根据研究的数据,松弛下垂的阴茎平均长度为9.16cm,勃起的阴茎平均长度为13.12cm。合格的松弛下垂的阴茎周长为9.31cm,勃起的阴茎则为11.66cm。一张尺寸分布的表格显示离群是罕见的。16cm的勃起阴茎处于95%以外,言下之意为100位男性中,只有5位的阴茎长于16cm。相反的,测量的勃起阴茎为10cm的在5%以外,意味着100位男性中只有5位的阴茎小于10cm。
    
绅士们,如果你渴望知道如何衡量,你需要使用本研究中所使用的相同的测量方法。所有长度测量均从耻骨向阴茎的顶侧即龟头的尖端。任何覆盖尺骨的脂肪在测量前要被压缩,并且包皮所提供的任何额外的长度均不计算在内。圆周测定在阴茎根部或中部阴茎轴的周围,因为这两个部位被视为等同。
    
研究人员得出结论,没有强有力的证据证明阴茎大小可以关联到其他物理特征上,如身高、身体质量指数,甚至是鞋的大小。是的,似乎唯一明确的结论是:穿大袜子家伙,他可能有大的脚。同样的,研究发现生殖器的尺寸和种族与种族之间无显著相关性。然而Veale指出,他们的研究目的并不是用来探测此因素的,因为大部分用于研究的数据来自白人男性。
    
我们很容易嘲笑可怜的乔治•科斯坦萨,因为他的男子汉气概萎缩了,但是报道显示只有55%的男性满意自己的阴茎大小。在色情行业中,根据Veale提到,一些人为此寻求潜在的危险的手术解决方案,“男人往往会低估它们的大小,他们似乎对别人的尺寸有一个扭曲的画面,并且他们会认为自己也应该有这样大的尺寸。”这可能就是在色情行业里,男演员常常因为有非常巨大的生殖器而被选中的部分原因。同样的,Herbenick指出,在无数的的垃圾邮件中提到勃起的阴茎平均长度应为17.78cm。实际上,98%接到此类邮件的邮箱的拥有者认为这是正确的。在任何情况下,最好是不理会这些广告,他说:“没有有效的外用药或药丸。”

男性福音:美科学家成功研发人造男性生殖器

  俗话常说,阴茎是男人的命根子,失去它,是男人的最大耻辱。虽说现实生活中,男人失去下体的可能性很低,但终究是存在这样的风险。据《观察家报》报道,科学家已经在实验室培育出一种人造阴茎,来帮助那些遭受先天性阴茎畸形或者阴茎外伤的男性。这种工程设计的阴茎是由美国北卡罗来纳州维克森林可再生医学研究所的研究人员研发出来的,目前这一技术正等待获得在人类身上进行测试的许可。 这项研究是由美国

实验室培育的男性生殖器即将到来

美国北卡罗莱纳州Wake Forest再生医学研究院的最新突破是男性生殖器。 实验室之前已经培育出了30种不同的器官,其中包括肾脏、心脏、膀胱、尿道和阴道,现在清单上又加上了阴茎。 研究人员已经成功培育出6条人类阴茎,现在他们正等待食品和药物管理局的批准,进入到人体(in-man)测试阶段,他们希望最终能替换受伤或先天畸形患者的生殖器。
