Mormonism claims that a woman cannot become a God, while a man can.

“Women are queens and priestesses, but not Gods. The Godhead, the ‘Presidency of Heaven,’ is a presidency of three male deities, similar to a stake presidency whose members each have wives who are responsible for domestic religious education, but not ecclesiastical functions.”
