IUI for ovulation before mikveh?

7 June, 2017


I am 30 years old and have a 3 year old. We began trying to conceive again with no success for a year, so we have started fertility treatment. The doctor suggested IUI because my period is long (7 days) so I am going late to the mikva, and this could be the reason.

What is the halacha in that case? Can I have a IUI during the 7 nekiim?

Thanks a lot, I have a lot of questions so if there is any posibility to speak to someone that would be amazing.


We are sorry to hear of your difficulty conceiving.

it is not clear from your question if you have tested your ovulation to determine its precise timing or if you have explored other measures to delay ovulation. Before moving ahead to treatment, we suggest first confirming that you cannot reach the mikveh sooner. You can read more about all these topics in our article on ovulating before immersion.

That being said, when necessary, IUI can be permitted during the clean days. We follow the halachic position that in that case, the clean days are paused from the day of IUI though the next three days, and then the count is resumed followed by immersion.

We do recommend having a conversation about this. To learn more about consulting a Yoetzet Halacha Fertility Counselor, please click here.
