Biologically, there are 3 genders – male, female and intersex (those whose organs and/or hormones do not fit into one category or the other).
Identity-wise, there are a lot more, and here the experts do not agree on one number. Some say there are 12 genders, but some go up to more than 70.
Unfortunately, this article is not so broad to cover all 70+ genders, but we will try to cover the most common ones.
