Effect of re-biopsy and re-vitrification on clinical outcomes in preimplantation genetic testing for aneuploidy.
Purpose: To investigate whether re-biopsy and re-vitrification affect embryo developmental potential and clinical outcomes.
Methods: Embryos that underwent preimplantation genetic testing for aneuploidy (PGT-A) and single embryo transfer between December 2017 and April 2024 were studied. All embryos were categorized into three groups: fresh biopsy and vitrification (BV group; n = 346); thawed, biopsied, and subsequently vitrified (VBV group; n = 12); fresh biopsied, vitrified, further thawed and biopsied again due to inconclusive results from the previous biopsy (BVBV group; n = 19). The live birth rate and miscarriage rate will be evaluated after embryo transfer in each group.
Results: Live birth rate (LBR) was not statistically significant among the BV group (50.00%), VBV group [41.67%; adjusted relative risks (aRR) 0.96; 95% confidence interval (95% CI): 0.81-1.14], and BVBV group (42.11%; aRR 0.97, 95% CI: 0.83-1.13). The miscarriage rate was not statistically significant: BV group (11.27%); VBV group (25%; aRR 1.09, 95% CI: 0.95-1.25), and BVBV group (5.26%; aRR 0.97, 95% CI: 0.91-1.02).
Conclusions: The differences in LBR and miscarriage rates among the groups were not statistically significant. However, the limited sample sizes of the VBV and BVBV groups cannot rule out the possibility of moderate differences. Some embryos can be successfully salvaged, leading to live births. To minimize inconclusive results, the laboratory should refine the procedural details.
期刊介绍：
The Journal of Assisted Reproduction and Genetics publishes cellular, molecular, genetic, and epigenetic discoveries advancing our understanding of the biology and underlying mechanisms from gametogenesis to offspring health. Special emphasis is placed on the practice and evolution of assisted reproduction technologies (ARTs) with reference to the diagnosis and management of diseases affecting fertility. Our goal is to educate our readership in the translation of basic and clinical discoveries made from human or relevant animal models to the safe and efficacious practice of human ARTs. The scientific rigor and ethical standards embraced by the JARG editorial team ensures a broad international base of expertise guiding the marriage of contemporary clinical research paradigms with basic science discovery. JARG publishes original papers, minireviews, case reports, and opinion pieces often combined into special topic issues that will educate clinicians and scientists with interests in the mechanisms of human development that bear on the treatment of infertility and emerging innovations in human ARTs. The guiding principles of male and female reproductive health impacting pre- and post-conceptional viability and developmental potential are emphasized within the purview of human reproductive health in current and future generations of our species.
The journal is published in cooperation with the American Society for Reproductive Medicine, an organization of more than 8,000 physicians, researchers, nurses, technicians and other professionals dedicated to advancing knowledge and expertise in reproductive biology.
