Ayelonit

In Rabbinic Judaism, an ayelonit (Hebrew: איילונית "ram-like woman", Hebrew pronunciation: [a.je.loˈnit]) is an individual assumed to be female at birth who later developed male secondary sex characteristics and is assumed to be infertile.

The secondary-sex characteristics referred to as "male" can include a deeper voice, painful intercourse, small breasts, a lack of pubic hair, menstruation, and a normal libido according to Maimonides' Mishneh Torah, Hil. Ishus, 2:6.

In traditional Judaism, gender plays a central role in legal obligations (see tractate Kiddushin 33b.). Thus, the archaic gender-sexual identities identified by the Talmud such as ayelonit, androgynos, tumtum, and saris, were created to fit into the legal system or halakha and do not correspond well to the current understandings of gender identity.
