Chorionic Villi Sampling (CVS)

19 June, 2017

Question:

Does a cvs (chorionic villus sampling) procedure that causes spotting render someone a niddah?


Answer:

In CVS, a small needle is inserted either via the abdomen or via the cervix to get tissue for examination. In the latter case, a tenaculum is used to grab the cervix, which often causes cervical bleeding. This type of bleeding is considered dam makkah and does not render one niddah. However, there generally is uterine bleeding as well which is caused by physical trauma to the uterus.  There is a halachic debate whether uterine bleeding due to trauma would render a woman niddah. The rabbi of this website, Rav Yehuda Henkin, rules that bleeding caused by such trauma does not make a woman niddah. Therefore, any spotting within a few days of CVS may be disregarded and does not render a woman niddah.
