Ask about their record-keeping, how you will be notified if a donor or a parent of a child conceived from a donor reports a medical or genetic issue, and their policy on creating large sibling groups. Lastly, it is important to note that the large majority of donor candidates who meet all the above standards for infectious and genetic safety and who have admirable characteristics are nevertheless rejected as donors at Fairfax Cryobank. For this reason, we recommend that even allowing for the variability in inheritance of specific genes from biological parents, significant thought be given to choosing a sperm donor who has the qualities that one might like to see in one's child.
How to Choose a Sperm Donor
How much does genetic inheritance really matter in determining what kind of person one becomes? The best proof comes from long-term studies of identical twins - who are genetically identical - but who have been separated near the time of birth and thereafter reared apart. Using fresh sperm always carries some risk that the donor may have been exposed to HIV or other diseases so recently that it would not produce abnormalities on concurrent laboratory testing.
Optimizing the environment, broadly defined to include good nutrition, parental love, facial sperm educational opportunities, and more will of course help each child reach its full potential. Another important safety consideration is minimizing the risk of transmission of a genetic disease to the child. If you think you may want to have more than one child from the same donor, find out if other vials of sperm donations available from this donor.
