Ovarian Follicle Size Is Key When Planning For Trigger Shot

Question:

Dear Doctor Ramirez,

I had 3 follicles when I received the trigger shot. 30mm 24mm and not sure what size the 3rd one was. Is the 30mm follicle a good size to have a mature egg to be released?

Thanks, G. from the U.S.

Answer:

Hello G. from the U.S.,

I'm sorry to say but those follicle sizes are way too big. The trigger should be given when the follicle is between 18-23 mms. Once larger than that, the egg becomes over mature and non-viable. In some cases the follicle will not ovulate and be retained as a retained physiologic cyst. This type of situation generally occurs when patients are seeing the wrong type of doctor. I would advise that you consider seeking out a specialist in infertility or at least an ob/gyn who knows how to monitor your cycle properly so that you trigger at the correct time.

Good Luck,
