Are there more than 2 genders or sexes?

Jul 18, 20

One study suggests that many people experience themselves sometimes as a woman and at other times as a man, or as neither.

A study by Daphna Joel, Professor of Psychology and Neuroscience at Tel-Aviv University, assessed gender identity in about 10,000 individuals and found (for trans and cisgender individuals) that the same person can identify as male, or female, or neither, at different times.
