sex”这个词（起源于拉丁词secare：切割、分开）最初只不过用来将人类划分为两个群体：女性和男性。每个个体属于这两个群体中的一个，既，属于两性中的一个。一个人要么是女性，要么是男性。

The word "sex" (from the Latin secare: to cut, to divide) originally refers to nothing more than the division of the human race into two groups: females and males. Every individual belongs to either one of these groups, i.e. to one of the two sexes. A person is either of female or male sex.

However, upon closer inspection, the matter is not quite that simple. In some cases it can be extremely difficult to determine whether a particular individual is female or male.
