You can trash them or give them out (to another person or for use in medical research or training). In either case, you and your spouse or donor (if applicable) will have to provide your consent in writing. Your fertility clinic should give you the necessary forms.
Donate them to another person: Gift another family or individual the most valuable gift by giving them your unused embryos.
Donate them to research: Medical research on embryos, eggs, and sperms helps scientists understand the root causes of infertility and create effective treatments.
Donate them to training: Students training to become embryologists need biological material to practice techniques like removing embryo cells and mastering the embryo freezing or thawing process.
Discard them: Instead of donating embryos, some people prefer to trash them. Embryos that are not needed anymore are removed from storage and left to perish in water or warmer.
