Follicular Volume at the Time of Final Oocyte Maturation in Poor Responders, and Its Correlation With Oocyte Maturity

The only additional measure will be the measurement of the follicle volumes on the day of trigger and before oocyte pick up procedure. This will be performed at the same time as the pre Oocyte pick up ultrasound prior to the patient admission to the recovery room for preparation. The ultrasound that will be used already has a pre build program that calculates the follicular volume automatically and hence not extending the ultrasound time.
