- Аннотация: Purpose of study: to assess clinical outcomes of IVF programs after transfer of low quality microsurgically defragmented blastocysts.Materials and methods: The study included 20 embryos of the 5-6th day of development, reached the blastocyst stage, whose trophectoderm was assessed as "C", due to presence of 15 to 35% of cytoplasmic fragments. Blastocysts underwent assisted hatching, followed by micromanipulation defragmentation. After defragmentation, the quality of embryos was re-assessed and used for embryo transfer (ET) or cryopreservation, followed by ET in cryocycle. The results of 20 clinical cases were analyzed with a known clinical outcome after the transfer of one defragmented blastocyst.Results: 2 hours after defragmentation, trophectoderm of all 20 blastocysts was rated not lower than category "B". After ET the following was diagnosed: no pregnancy - 12 cases; early pregnancy loss - 2 cases; ongoing pregnancy resolved by live birth - 6 cases.Conclusion: Defragmentation of low-quality blastocysts makes it possible to improve their morphological assessment. Clinical outcomes of IVF programs using defragmented blastocysts are comparable to those of good quality blastocyst transfer, including live births rate.
