A popular belief in my hometown was that a young woman could not become pregnant the first time she had intercourse. This idea did not originate in Fort Wayne, Indiana; in fact, this idea is found on our daf. The Gemara asks: But isn’t it known that a virgin woman does not become pregnant from her first sexual act?
This statement is repeated on Yevamot 34 a and b. The text, in its context, is discussing why the Mishnah insists that a woman must wait three months after the death of her husband or following a divorce before entering into a second marriage. The idea behind the law is that by waiting they will insure that, should the woman become pregnant, there is no confusion as to who is the father of the child. In the above discussion, the Gemara asks why a couple is required to wait three months to consummate a marriage through the act of intercourse when everyone knows that “no woman becomes pregnant in the first act of intercourse.”
Yet, the daf is aware that some women did seem to get pregnant upon the first act of intercourse, and so they sought to explain this.
Idea 1: Rav Naḥman said that Rabba bar Avuh said: This is referring to a situation where they engaged in intercourse and then repeated the act, so that it is possible that the women were impregnated during the second act of intercourse.
Idea 2: But didn’t Tamar become pregnant from the first act of intercourse? Rav Naḥman said: Tamar broke her hymen with her finger prior to intercourse, and it is due to this that she became pregnant from the first act of intercourse, as Rabbi Yitzḥak said: All of those women from the household of Rabbi Yehuda HaNasi who break their hymens are named Tamar by nickname. And why are they named Tamar? They are called this on account of Tamar, who broke her hymen with her finger.
Oy! Even the biblical examples of pregnancy upon first encounter cannot persuade our Rabbis that their logic may be faulty. Lot’s daughters are also used as an example, and then dismissed.
Is this ripped from the headlines? Is this where Todd Atkin’s gets his horrific assertion that a woman cannot get pregnant from rape?
No. But it does show a long line of tradition of men making statements about how a woman’s body works and being wrong. It shows that just because a man has authority in one area, does not mean that he should talk about things in areas he does not know as much about.
