Are egg donation cycles ever cancelled?
Cancellation of an egg donation cycle is unlikely but may occur if the donor: • Fails to respond to the medication • Responds too strongly to the medication • Changes her mind regarding the donation cycle These events occur very infrequently. From 1992 through 2005, the Center for Assisted Reproduction initiated 480 egg donation cycles and had but four cancellations. Of these cycles, we have had 333 positive pregnancies.
