Abstract
Purpose: Our aim was to evaluate if maternal age at transfer following autologous oocyte cryopreservation is associated with live birth rate (LBR).
Methods: We performed a retrospective cohort study of all patients who thawed autologous oocytes and then underwent a single frozen euploid embryo transfer between 2011 and 2021 at a large urban university-affiliated fertility center. Each oocyte thaw patient was matched 2:1 to in vitro fertilization (IVF) patients who underwent single embryo transfer < 1 year after retrieval. Primary outcome was LBR. Secondary outcomes included implantation rates (IR) and spontaneous abortion rates (SABR).
Results: A total of 169 oocyte thaw patients were matched to 338 IVF patients. As expected, oocyte thaw patients were older (median age 42.5 vs. 37.6 years, p < 0.001) and waited longer between retrieval and transfer than in vitro fertilization patients (median time 59 vs. 1 month, p < 0.001). In univariate analysis, implantation and LBR differed among oocyte thaw and IVF patients (p < 0.05), but SABR did not (p = 0.57). Transfer outcomes in oocyte thaw patients did not differ based on transfer age group (IR: p = 0.18; SABR: p = 0.12; LBR: p = 0.24). In a multiple logistic regression model, age at transfer was not predictive of live birth when controlling for age at retrieval, embryo morphology, and day of blastulation.
Conclusions: Maternal age at transfer after oocyte cryopreservation is not predictive of LBR; this suggests that "an aging womb" does not impair LBR after oocyte thaw and empowers patients to return for transfer when ready for childbearing.
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.
