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.
