A cis man is someone who was assigned as male at birth (AMAB) and their gender identity is also male. A cis-man cannot have PMDD as they do not have female reproductive organs and therefore do not have a menstrual cycle. That is not to say that they cannot have a sensitivity to hormone fluctuations, but they would not have the regular and cyclical pattern of a menstrual cycle.
