The ratio of length between a man's second and fourth fingers (2D:4D) is thought to be linked to the amount of testosterone he received in the womb. According to new research, it also shows something else: How attractive a man's face will be to women.

The research looked at the relationship between the 2D:4D ratio, how attractive women thought the face was, and other signs associated with attraction and testosterone production: body smell and voice.

Men with a lower 2D:4D ratio (shorter pointer and longer ring fingers) were thought by the subjects to be more attractive, have more "masculine" features, and have more symmetrical faces.

However, the men's smell and voices — both of which are linked to testosterone levels and attraction — didn't correlate with the ratio. Scientists say this implies that facial structure is influenced by the hormone during pregnancy, and voice and odor by testosterone levels later in life.

研究發(fā)現(xiàn)：男性食指和無名指的長(zhǎng)度比例，關(guān)系到他在母親子宮內(nèi)獲得的睪丸素多少。同時(shí)這也決定了該男子面貌吸引MM 的能力。

來自日內(nèi)瓦大學(xué)研究人員得出的結(jié)果是：食指 > 無名指 食指 < 無名指，將更加陽(yáng)剛、臉部更加對(duì)稱，所以也更被MM 們所喜歡。

除此之外，其他于睪丸素有關(guān)的體毛特征暫與這個(gè)比例無關(guān)。

# oioi：原來我們老聽說這兩根手指與GAY什么的有關(guān)。現(xiàn)在卻是這個(gè)？！

研究人員收集到了49名男性自愿者的照片、錄音、體味，然后分別叫了兩組女性來打分，得出的結(jié)果。
