Trust Experience

Choosing the right sperm bank makes choosing the right sperm donor easy. Since 1977, California Cryobank has set the standard for genetic screening, specimen quality, and customer service while providing an unmatched selection of premium donor sperm.

You have turned to California Cryobank to help you with one of the most important decisions you will ever make, and we are proud to work hand-in-hand with you to help realize your dream. The reputation for success we have built over almost forty years in reproductive and sperm bank services speaks to the value we place in the process; every detail matters in ensuring that you will ultimately have the best experience possible.

Choosing A Sperm Donor

Obviously choosing a sperm donor is a significant decision and one that takes some time. At California Cryobank we first set a solid foundation from which you can begin to make your choice; and that foundation is built on our stringent, industry leading screening process for donor sperm. First and foremost, we actively recruit donors from top US universities who must meet our basic requirements:

  • Must be at least 5'8" or taller
  • Between 19-38 years old
  • Currently attending or have graduated from college
  • Must be in good health
  • Legally allowed to work in the US

Those who meet these requirements may then be considered to move onto the next step which is our qualification process; the standards of which see only 1% of applicants ultimately accepted into our donor sperm program. Our qualification process conforms to our unwavering benchmarks by which potential sperm donations are measured and includes everything from extensive medical testing to genetic screening that allow for the best insemination procedures further down the road.

CCB Proudly Features

  • Almost 40 years of experience in successful donor insemination pregnancies
  • The industry's largest and most diverse donor selection
  • High standards which allow less than 1% of applicants into our donor program
  • FDA registration and compliance
  • Accreditation by the American Association of Tissue Banks (AATB)
  • Full-time genetic counselors on staff

The process of donor sperm qualification at California Cryobank is extensive to be sure. But everything that we do is to maintain our standards of excellence so that we can offer our members the best of the best at all times.

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.
