Egg retrieval is often done through a procedure called transvaginal ultrasound aspiration. During this procedure, an ultrasound probe is inserted into the vagina to identify the follicles. A needle is then guided through the vagina and into a follicle. A suction device connected to the needle is used to remove the egg from the follicle. Multiple eggs can be removed from multiple follicles in about 15 to 20 minutes.
