Abstract: Objective:To investigate the treatment of an embryo with the partial dissolution of zona pellucida on day 2 and summarize the identification and treatment of embryos without zona pellucida during culture.Methods:A case of one live baby from an embryo with the partial dissolution of zona pellucida transferred on day 2 was retrospectively analyzed.Results:Through reducing the transplant cleaning process, the patient got pregnant and delivered a live girl baby at 39 +3 weeks of gestation. Conclusion:The early dissolution of zona pellucida may affect the compaction process of embryos, but a good outcome can still be obtained by carefully selecting embryos and reducing the washing process of embryo transfer.
