Men and women are fundamentally different, however the differences are not only restricted to their physical characteristics. Mentally and emotionally men and women have been proven to differ in a variety of ways. Given below are some ways in which the two genders differ:

Physical characteristics: Let's start with the fundamental difference. Men and women both possess two halves of the reproductive system, namely the vagina for the females and the penis for the males. Also, women possess breasts, while men do not.

Secondly, males have more body and facial hair than females (in most cases). Men tend to be burlier than women, frame wise.

Now coming to mental and emotional differences; Women are apparently more sentimental than men. Men attend to be more physically aggressive. Differences aside, the physical and mental characteristics of both genders are endowed to serve a specific purpose each; however the scope of this discussion can only be limited to so much.
