It usually takes a longer time to be matched with a gestational carrier than to find an egg donor. A lot of intended parents prefer to find the egg bank and egg donor to carry out the egg retrieval while still waiting to be matched with a Surrogate mother. This will give the parents peace of mind, knowing that they have frozen embryos that are ready for use when the Surrogate completes her screening. If you will be doing genetic testing on the embryos, it’s required that you have the embryos frozen until the results are known. So, you don’t have any reason to wait until you’re matched with a Surrogate mother before you purchase your egg cohort.
