Overview

• Thaddeus Daniel Pierce was born on July 26, 2025, in Ohio from an embryo cryopreserved since May 1994, setting a new record of roughly 11,148 days in storage.
• Born after a challenging delivery, Thaddeus is described by his parents as remarkably calm and both he and mother Lindsey Pierce are now healthy and thriving.
• The embryo, one of three donated by Linda Archerd through the Snowflakes adoption program, was thawed and transferred at Dr. John Gordon’s Rejoice Fertility Clinic in Tennessee.
• This milestone highlights advances in vitrification and other cryopreservation techniques that have vastly improved post-thaw embryo survival rates.
• The birth has reignited calls for clearer regulation of the estimated 1.5 million surplus embryos stored across U.S. clinics without a federal preservation time limit.
