Follicle Size & Egg Maturity: Understanding Optimal Sizes for IVF


Question
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?

Answer
Hello Gerri 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.

Good Luck,
