en 32500013 <p>Background: The purpose of this study was to assess whether the outcomes from IVF-preimplantation genetic testing (IVF-PGT) cycles for single gene defects (SGD) (PGT-M) differ between a privately funded period (PRP) and publicly funded period (PUP).&nbsp;&nbsp;<br /> Methods: A retrospective cohort study was conducted in a North-American single tertiary center. The PRP (March 1998 to July 2010) comprised 56 PGT-M cycles from 58 IVF cycles in 38 couples, and the PUP (August 2010 to May 2015) comprised 59 PGT-M cycles from 87 IVF cycles in 38 couples. One PGT-M cycle is defined as one biopsy procedure from one or serial IVF cycles. A p-value of 0.05 was considered statistically significant.&nbsp;<br /> Results: The clinical pregnancy rates (CPR) per PGT-M cycle were 30.4% and 52.5% in each period, respectively (p=0.021). The live birth rates (LBR) per PGT-M cycle were 21.5% versus 40.9% in each period, respectively (p=0.037). A sub-analysis within the PUP comparing 39 PGT-M cycles from 39 IVF cycles with 20 PGT-M cycles from 49 IVF cycles yielded CPRs per PGT-M cycle of 64.1% and 30.0% and LBRs per PGT-M cycle of 53.8% and 15.0%, in each group, respectively (p&lt;0.05 for both).<br /> Conclusion: The transition from private to public funding and a single embryo transfer (ET) guideline has little impact on embryological and clinical outcomes of PGT-M cycles, and results in lower rates of multiple pregnancies. However, these two systems may serve different populations.&nbsp;</p> In Vitro, Preimplantation genetic testing, Public funding, Single embryo transfer, Single embryo transfer 107 116 https://www.jri.ir/article/60079 https://www.jri.ir/documents/fullpaper/en/60079.pdf TalyaShaulovMUHC Reproductive Centre, Department of Obstetrics and Gynecology, Montreal, Quebec, Canada62044LiZhangMUHC Reproductive Centre, Department of Obstetrics and Gynecology, Montreal, Quebec, Canada62045Jin-TaeChungMUHC Reproductive Centre, Department of Obstetrics and Gynecology, Montreal, Quebec, Canada62046Weon-YoungSonMUHC Reproductive Centre, Department of Obstetrics and Gynecology, Montreal, Quebec, Canada62047WilliamBuckettMUHC Reproductive Centre, Department of Obstetrics and Gynecology, Montreal, Quebec, Canada62048AsanglaAoMcGill University Health Centre Research Institute, Montreal, Quebec, Canadaasangla.ao@muhc.mcgill.ca62049
