Menstrual cup when trying to conceive

27 December, 2018

Question:

I read an article recently suggesting that menstrual cups could make it easier to conceive. It seems that women insert the cup after relations to encourage more sperm cells to enter the cervix. And apparently sometimes the husband withdraws during relations and deposits semen directly into the cup, which the wife then inserts. What are the halachic issues with this?


Answer:

It is important to know that these methods of enhancing conception are medically unproven.

Because the halacha of hotza'at zera levatalah (spilling of seed) is very strict, using a menstrual cup to capture semen in the midst of relations is prohibited.

Inserting a menstrual cup after relations have been completed normally would be halachically permissible as long as there is no medical contraindication. For safety reasons, the menstrual cup needs to be removed within 12 hours.

Even a drop of blood found on something inserted internally can make a woman niddah. Therefore, if a woman uses a menstrual cup when she is tehorah, we recommend removing and immediately rinsing it without looking.

In cases where a couple suspect that they need help conceiving, there are many possible paths to pursue. We encourage couples in this situation to consult a yoetzet halacha and health care provider for guidance before deciding on a course of action.
