I read your query and understand your concerns. Following is my reply: 1) It takes 36 hours for ovum to rupture. I think you time your IUI 36 hours after trigger. 2) Single IUI after 36 hours of trigger is good enough. 3) Next day scan might reveal a ruptured follicle. I hope I answered your query. I will be available for any followup queries you have. Regards, Dr.Mahesh Koregol IVF & Infertility Specialist </s>
