Donor Screening: Genetic Evaluation

The goal of our genetic evaluation is to reduce the risk for significant medical problems in the donor's offspring. If a donor applicant is considered to have an increased risk for having offspring with significant health problems, above the general population risks, he is disqualified from becoming a California Cryobank donor.

We strongly recommend that you download your donor's family Medical History and Genetic Test Summary (GTS) and discuss them with your personal healthcare providers before you ship your vials. Both items are available free of charge and can be found on your donor's profile page. There is a 3 - 4% chance that a child will be born with a health problem that cannot be predicted or tested for prior to pregnancy regardless of the screening performed, but we attempt to reduce the risks through these comprehensive evaluations:

Family Medical History

Changes in Donor Medical History

Our Reproductive Genetic Specialists evaluate all medical issues and updates received about a donor's personal or family medical history or an offspring's medical history.

Donor Updates

All donors are asked to inform us of changes in their personal or family medical histories that occur after they have retired from our program so that we can make this available to clients and donor-conceived persons for their medical records. Clients are welcome to contact the Genetics Department to learn of any updates on their donor as they may want to include them as part of their child's medical records. Our team may also notify you about significant donor updates if the information could be relevant for management of your child's health.

Offspring Updates

All clients are asked to inform California Cryobank if their child or fetus has a significant medical problem. One of our Reproductive Genetic Specialists creates a confidential report and reviews the information along with all other medical history for that donor to determine the appropriate management. You can report a medical problem by calling our Reproductive Genetic Specialists at 877-732-6384 or online.

National averages range from 3-4 insemination cycles per successful pregnancy. We recommend purchasing at least 5 vials per child to guarantee your donor remains available until reaching your personal family goals. Additionally, you get 1 Year FREE storage if you purchase 4 or more vials ($475 value).


Our donors sell out and retire quickly! We have thousands of clients forced to choose between a new donor or not having a second child because they chose not to store vials for future use while they were available. To help you plan for your future, we offer 3 Years FREE storage if you purchase 3 Years+ vials ($1,050 value) - as well as the ability to sell back any unused vials that have not left our control.
