Is the testimony of individual women accepted when one spouse claims the other admitted that the first spouse is their sibling by suckling relationship?

Primary text

The testimony of isolated women is not accepted when one spouse alleges the other admitted that the first spouse is their sibling by suckling relationship, and the accused spouse denies it. This is because the claim concerns an admission, and admissions are matters that men can witness. Therefore, the testimony of isolated women, which is required for establishing the suckling relationship itself, is not required or accepted for establishing the admission of that relationship.
