Overview

• Thaddeus Daniel Pierce was born on July 26, 2025, to Ohio residents Lindsey and Tim Pierce from an embryo frozen since 1994.
• The embryo was donated by its original owner, Linda Archerd, through Nightlight Christian Adoptions’ Snowflakes program based on her preference for a white, Christian couple.
• At more than 30 years in liquid nitrogen, the embryo sets a new record for the longest interval between cryopreservation and live birth.
• Infertility specialists, including Dr. Anjali Malpani, say the healthy outcome demonstrates that long-term cryopreservation does not increase risks of birth defects.
• Rejoice Fertility Clinic and the adoption agency are tracking the case for ongoing bioethics review and research into best practices for extended embryo storage.
