Pregnancy outcomes in patients with non-obstructive azoospermia undergoing micro-TESE: comparison of fresh vs. frozen-thawed testicular sperm.
Background: The relative merits of fresh or frozen testicular sperm in ICSI remain a matter of contention. This study aims to compare the reproductive outcomes of non-obstructive azoospermia patients undergoing ICSI using fresh and frozen-thawed microdissection testicular sperm extraction (micro-TESE) sperm.
Methods: A total of 223 men with non-obstructive azoospermia underwent micro-TESE to collect testicular spermatozoa. ICSI cycles were performed using fresh and frozen-thawed spermatozoa. The cleavage states and grading of embryos, fertilization, and pregnancy outcomes were compared between the groups to assess the impact of cryopreservation of testicular spermatozoa on embryo quality and ICSI outcomes.
Results: A total of 223 cases were evaluated, with fertilization observed in 208 cases and no fertilization observed in 15 cases. The number of day 3 total embryos and the number of cleavage embryos differed between the fresh and frozen micro-TESE groups, whereas the number of two-pronuclei oocytes, grading of embryos, fertilization, pregnancy, and live birth rates were found to be similar between the two groups.
Conclusion: The cryopreservation of spermatozoa obtained by micro-TESE does not affect the fertilization rate or pregnancy outcome in cases of non-obstructive azoospermia. The present findings, when considered in conjunction with the extant evidence, may serve to alleviate concerns regarding the utilization of frozen-thawed micro-TESE sperm in patients with non-obstructive azoospermia.
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.
