韩国研究人员解谜男性秘密

Researchers in South Korea think they've finally been able to crack the code that indicates the size of a man's penis, and it comes down to a ratio of finger length on the right hand.

韩国研究人员认为他们终于解谜了男性生殖器长短之谜，原来男性阴茎的长短和右手手指的长短比例有关。

"According to our data ... the shorter index (second) finger than ring (fourth) finger you have, the longer stretched penile length you have," wrote Tae Beom Kim at the urology department of Gachon University Gil Hospital in Incheon, South Korea, in reply to questions from Reuters.

“我们的数据表明……食指比无名指短得越多，那么你阴茎勃起时的长度就越长，”韩国仁川Gachon大学Gil医院泌尿科专家Tae Beom Kim接受路透社采访时说。

Previous studies have shown strong evidence that prenatal testosterone may determine finger development as well as penile length, a relationship that Kim and his colleagues launched a study to focus on.

早前的研究表明睾酮分泌的多少会决定手指的生长和阴茎的长短，这是Kim和他的同事们之前研究的课题。

Researchers at Cachon University in Incheon, Korea studied 144 men over the age of 20 who were getting urological surgery.

韩国仁川Cachon大学的研究人员对20岁以上到该医院做泌尿手术的144名男性做了研究。

The researchers "suggest that the digit ratio can predict adult penile size and that the effects of prenatal testosterone may in part explain the differences in adult penile length," according to the abstract of the study.

在这份研究摘要中，研究人员“认为手指长短比例能够预测成年男性生殖器大小，睾酮可能是导致男性生殖器长短各异的影响因素。”
