Female refers to the gender of a species who produces eggs. Female humans are most notably identified by higher levels of estrogen, and the presence of a vagina, uterus, and ovaries.  Female humans are usually referred to as women.
However some males and transgenders consider themselves female due to their sexual orientation, hormonal imbalances, or other reasons. This sometimes can result in confusion and disagreement of definitions between people that consider themselves female, and others who do not.
Role in societyEdit
Main article: Gender roles
Typically throughout history, women have been seen as mothers, who's key responsibilities to her family and society were to give birth to and raise children; whereas the man's job typically has consisted of providing for the family. As time has progressed, however, this has gradually changed into how it is commonly seen today: where the male and female share most responsibilities, including working and raising child(ren); or it might even be seen reversed, for the woman to be working and providing for the family while the father stays home and takes care of the child(ren).
