Ovulating before IUI

hopeful34

I have heard lots of things about when you are supposed to O after a trigger. I do Ovidrel and they have me do it at 11pm and come in 2 days later and the iui is around 36 hours after trigger. I don't understand why my RE doesn't do an u/s before the iui to see if I have already O'd...I dont' think they care and they only care about getting paid for iui even if it's too late. I know some of your RE's do an u/s. Should I ask for one the day of iui to make sure i haven't O'd???

Well even if you already ovulated, as long as your IUI is within about 12 hours of O you're fine. I don't think there is any way that they can tell if you JUST ovulated or not by u/s. You should O about 36 hours after the trigger. GL.

My RE does not do any monitoring between the trigger and IUI 36 hrs later. I use the fertilityplus website a lot, one of their FAQs states:

Q: When is the best timing for an IUI?

A: Ideally an IUI should be performed within 6 hours either side of ovulation ? for male factor infertility some doctors believe after ovulation is better, otherwise chances of success are higher with insemination before ovulation with the sperm waiting for the egg. When timing is based on an hCG injection, the IUIs are usually done between 24 and 48 hours later. Typical timing would be to have a single IUI at about 36 hours post-hCG, though some do it at 24 hours, and some clinics are reporting better results when doing the IUI at 40-42 hours post-hCG. If two IUIs are scheduled, they are usually spaced at least 12 hours apart between 24 and 48 hours after the hCG. Some reports show no increase in success rates with two IUIs, but others suggest it may increase success as much as 6 percent.

Some doctors will base timing of IUI on a natural LH surge. In that case, a single IUI at 36 hours is the norm, but doing them at 24 hours is also pretty common since ovulation may be a bit earlier. When two inseminations are planned, they are usually timed between 12 and 48 hours after the surge is detected.

The egg is only viable for a maximum of 24 hours after it is released.
