Intrauterine insemination (IUI) and ovulation timing

Yes, you can get an intrauterine insemination (IUI) during ovulation. There is a window where the egg could be fertilized, from around 3-5 days before ovulation until the day of ovulation (and maybe one day after ovulation). The day of ovulation might be the best day to do IUI – if you choose one IUI per month, we time it for the day of expected ovulation. For two IUIs a month, we choose the day before ovulation and the day of ovulation. If we are monitoring a treatment cycle with ultrasound and you have a decent-sized follicle and then get a positive LH surge, we recommend that you do an IUI on the day of your surge. The egg has up to 24 hours after ovulation when fertilization could occur.
