Certain gynecological procedures may render a woman niddah:
- If she bled during or after a procedure, she may be considered niddah. If, however, it is reasonably certain that the bleeding was caused only by the trauma of the procedure, then a rabbi may determine that she is not niddah.
- Even if no bleeding was detected, if the procedure involves a significant opening of the uterus, she may be considered niddah.
It is therefore important for a woman to discuss with her physician the details of any gynecological examination, procedure or therapy. She may also need to consult with a rabbi to determine its halachic implications. It is best to do so in advance, since she may be able to schedule the procedure so as to minimize her time as a niddah or to reduce her chances of becoming niddah at all.
This section discusses gynecological procedures and their halachic implications.
