Mixed up embryo biopsy tissue samples, Healing Reproductive Medicine says it is investigating whether there were external factors interfering.

The Heys Reproductive Medical Center experienced a suspected mix-up of embryo biopsy tissue samples. The center issued a late-night statement saying the anomaly occurred only in the processing of a small number of cell biopsy samples sent to the diagnostic center. The center has established an internal investigation team to carefully review and optimize all operational procedures.

Heys stated that in May this year, it performed preimplantation embryo cell biopsy chromosome testing for two couples receiving IVF and preimplantation genetic testing (PGT) services, and sent the samples to the Prenatal Genetic Diagnosis Center at the Prince of Wales Hospital, Chinese University of Hong Kong. The center received notifications from the diagnostic center on May 26 and June 4 that the samples were abnormal, with some samples not belonging to the patients.

Heys immediately initiated a genetic retesting process, performing new embryo cell biopsies and genetic retests for the two couples. After investigation, it was confirmed that the original embryos stored in the center’s liquid nitrogen bank were intact and safe, with no errors, mix-ups, damage, or other issues. The incident did not affect the couples involved.

Heys has proactively reported the matter to the Human Reproductive Technology Authority and is cooperating with the Department of Health and relevant authorities for a comprehensive review and investigation. The center proactively suspended accepting new cases from Monday afternoon (the 6th) until further notice.

Heys expressed deep shock over the incident, stating it will handle the matter seriously and fully cooperate with the police and relevant government departments. The investigation will include whether external factors interfered. Specific internal investigation measures include providing follow-up explanations and counseling for the two affected cases. The center has fully suspended fertility treatment services. Embryos, eggs, and sperm currently stored at the center will continue to be properly stored and will not be affected. During the suspension, the center will proactively contact all clients currently receiving reproductive services to offer free consultation, counseling, and genetic matching. For babies previously born through reproductive medical services at the center, genetic identification can be arranged if needed, and the care team will contact each family to discuss appropriate follow-up plans. For existing clients needing further treatment and services, the center will assist in transferring them to other medical centers.

Heys reiterated that after the incident, it has conducted careful genetic retesting for all PGT cases since January this year, and no abnormalities were found in the completed tests. It confirms that embryos, eggs, and sperm currently in storage will continue to be properly stored under strict standards.
