Womyn-born womyn

Womyn-born womyn (WBW) is a term developed during second-wave feminism to designate women who were assigned female at birth, were raised as girls, and identify as women (or womyn, a deliberately alternative spelling meant to challenge the centering of male as norm). The policy is noted for exclusion of trans women. Third-wave feminism and fourth-wave feminism have generally done away with the idea of WBW.

Events and organizations that have womyn-born-womyn-only policies bar access to anyone who was assigned male at birth: cis men, trans women, and male children older than a determined age.
