Patch to delay ovulation

3 June, 2018


I am under the care of a reproductive specialist who just prescribed the estrogen patch to delay ovulation. This is because I ovulate during the end of the clean days. I was wondering if there were any halachic complications regarding spotting, which I have read online is a common side effect. Are there any precautions to take?


We appreciate the sensitive nature of this question.

Sometimes, halachic measures can help address ovulation before immersion. Please see our article on the topic for more information.

Spotting can sometimes make a woman niddah or disrupt or delay the clean days. By taking halachic precautions, however, its impact can be limited. For more information on spotting and recommended precautions, please see our articles “Stains” and “Toilet Paper.”

If spotting becomes a problem during the shivah neki’im, a specific halachic question should be asked about it and about reducing the number of bedikot. When bringing stains or bedikot for evaluation, please be sure to mention that you are trying to conceive and taking estrogen to delay ovulation.

Please note that the patch and any residual adhesive need to be removed for mikveh immersion (soap and water, or a little oil, usually does the trick) and replaced with a new patch afterwards.

You may also find it helpful to consult a Yoetzet Halacha Fertility Counselor. (This is a free service, details here.)

We wish you success with your treatments.
