At what point does IUI take place?

Ana Fernández-Sanguino, gynaecologist at Fertility Madrid, tells us when to inseminate the woman in an IUI cycle:

We do the insemination 36 hours after the trigger. When we do the last control and we see the follicle that has normally between 17 or 18 millimeters diameter, we organized the time of the trigger and 36 hours afterwards we program the insemination.
