【 摘 要 】

BackgroundStudies have shown that supplementation with recombinant human GH (rh-GH) during ovarian stimulation (OS) may improve the ovarian response and clinical outcomes of IVF. However, it remains unclear whether GH is associated with the ploidy status of embryos, and therefore, is unable to explain the underlying reason for the effect of GH on IVF outcomes. This study aimed to investigate whether GH supplementation in women with advanced maternal age (AMA) during OS is related to an increased probability of obtaining euploid blastocysts.MethodsThis was a single center retrospective cohort study. The data of all women aged 38–46 years who underwent their first preimplantation genetic testing for aneuploidy (PGT-A) cycle between January 2021 and June 2022 were reviewed. Patients in the GH group received 4 IU/day subcutaneous GH supplementation from the beginning of OS to the trigger day, and patients in the control group did not. A total of 140 patients in the GH group and 272 patients in the control group were included after 1:2 propensity score matching.ResultsThe baseline and cycle characteristics between the two groups were similar. The proportion of cycles which obtained euploid blastocysts was significantly higher in the GH group than that in the control group (41.43% vs. 27.21%, P = 0.00). The GH group had a significantly higher euploid blastocyst rate per cohort (32.47% vs. 21.34%, P = 0.00) and mean euploid blastocyst rate per cycle (per biopsy cycle 0.35 ± 0.40 vs. 0.21 ± 0.33, P = 0.00; per OS cycle 0.27 ± 0.38 vs. 0.16 ± 0.30, P = 0.02). However, the benefit of GH was more significant in patients aged 38–40 years, but not significant in patients aged 41–46 years. Pregnancy outcomes were similar between the two groups after embryo transfer.ConclusionsGH supplementation during OS is associated with a significantly increased probability of obtaining euploid blastocysts in women aged 38–40 years, but this benefit is not significant in women aged 41–46 years. Our results explained the underlying reason for the effect of GH on IVF outcomes in existing studies, and might be helpful for AMA patients undergoing PGT-A cycles to obtain a better outcome meanwhile to avoid over-treatment.Trial registrationNCT05574894, www.clinicaltrials.gov.
