Wolffian is an alternative to the term "biological male." It refers to a DMAB/AMAB and the phenotypic sex traits of a person who has testicles and was exposed primarily to testosterone is the womb.[1] This term is best described as what society views as 'common men' or 'most men' however some transfeminine or transine women are wolffian as well as some non-binary or anonbinary people. Wolffian does not also fit all cisgender men, as some cisgender men are intersex.
A term similar to this is POP, however this term includes intersex and altersex individuals with penises. One who is wolffian is also a POP, although one who is a POP is not always wolffian.
The counterpart is Müllerian.
