INVERTING HERSELF AFTER RELATIONS WITH HER DERANGED HUSBAND - Yevamos 69 - Daf Yomi

Rabbah bar Rav Huna states: We are only concerned for pregnancy in cases of cohabitation during marriage; however, in cases that involve promiscuity, we are not concerned for pregnancy (because women who engage in illicit relations invert themselves after cohabitation in order to avoid becoming pregnant).

Tosfos writes: A Kohen’s daughter who is married to a deranged man is permitted to eat terumah. Although she assumes that her marriage is valid, she is concerned that she will not be able to tolerate him, and eventually will leave him. She therefore inverts herself after relations with her husband in order that she will not conceive and bear his children.

The Noda B’Yehudah (II Y”D:202) brings a question from Reb Zaruch Eidelwitz from Prague: The Tur (Y”D 331) rules that a Kohen’s daughter who is married to a deranged man is disqualified from eating terumah. How can that be if the kiddushin does not take effect even Rabbnically?

The Noda B’Yehudah’s son answers: The Tur disagrees with Tosfos, and maintains that a woman who is married to a deranged man is under the impression that her marriage is valid, and therefore she does not invert herself after relations. The Tur rules that she is disqualified from eating terumah because we are concerned that she might be pregnant.
