Sex - Definition

What do we mean by "sex"?

Biological symbols for female and male
Left: Female (Venus? Hand mirror? Vulva?)
Right: Male (Mars? Bow and arrow? Penis and testicles?)

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.
