Who are the donors?

At Cryos, we seek men and women from all ethnic backgrounds, and we pride ourselves in the diversity of our donors. All donors must complete a thorough screening process to minimize the chances of hereditary diseases being transferred to children born from their donations, and the main requirements as a donor at Cryos is to be in good health both physically and mentally. Donors at Cryos must choose between two types of donor profiles: Extended and Basic. The difference between the two profiles is the amount of information accessible. The donors must also decide whether to be ID Release or Non-ID Release. ID Release Donors agree to let Cryos release identifying information about them to children conceived from their donations. Once the child turns 18, they can enquire about the information. No information will ever be released about Non-ID Release Donors.
