Abstract Background Aneuploidy is the principal genetic factor leading to the failure of embryo implantation. For most patients who accept the non-preimplantation genetic testing (PGT) cycle, non-invasive methods to select euploid embryos with the best pregnancy potential are desirable Methods This retrospective study recruited women undergoing PGT for aneuploidy (PGT-A) with trophectoderm biopsy from January 2019 to December 2020. The ploidy status of embryos was determined by next generation sequencing (NGS). Results Altogether 2531 blastocysts from 839 PGT-A cycles were evaluated. The euploid rate of day 5 blastocysts seemed to be significantly higher than that of day 6 blastocysts, either from the same ovarian stimulation (OS) cycles (49.9% vs 35.7%, P < 0.001) or from different OS cycles (48.2% vs 27.8%, P < 0.001). Both the younger maternal age (adjusted OR = 0.917, 95% CI: 0.892–0.944, P < 0.001) and day 5 stage (adjusted OR = 1.735, 95% CI: 1.415–2.127, P < 0.001) were independently associated with the greater euploid rate of blastocysts. However, after single euploid embryo transfer, the clinical outcomes of day 5 blastocysts were comparable to those of day 6 blastocysts, no matter whether they were from the same OS cycles or not. Conclusions Our results revealed that day 5 blastocysts possess a higher euploid rate than day 6 blastocysts independent of the OS cycles. Giving priority to a day 5 blastocyst over day 6 blastocyst will increase the likelihood to select single euploid embryo for transfer in non-PGT cycles.

Previous studies have shown that increasing estradiol concentrations had a toxic effect on the embryo and were deleterious to embryo adhesion. In this study, we evaluated the physiological impact of estradiol concentrations on endometrial cells to reveal that serum estradiol levels probably targeted the endometrium in controlled ovarian hyperstimulation (COH) protocols. An attachment model of human choriocarcinoma (JAr) cell spheroids to receptive-phase endometrial epithelial cells and Ishikawa cells treated with different estradiol (10−9 M or 10−7 M) concentrations was developed. Differentially expressed protein profiling of the Ishikawa cells was performed by proteomic analysis. Estradiol at 10−7 M demonstrated a high attachment rate of JAr spheroids to the endometrial cell monolayers. Using iTRAQ coupled with LC–MS/MS, we identified 45 differentially expressed proteins containing 43 significantly upregulated and 2 downregulated proteins in Ishikawa cells treated with 10−7 M estradiol. Differential expression of C3, plasminogen and kininogen-1 by Western blot confirmed the proteomic results. C3, plasminogen and kininogen-1 localization in human receptive endometrial luminal epithelium highlighted the key proteins as possible targets for endometrial receptivity and interception. Ingenuity pathway analysis of differentially expressed proteins exhibited a variety of signaling pathways, including LXR/RXR activation pathway and acute-phase response signaling and upstream regulators (TNF, IL6, Hmgn3 and miR-140-3p) associated with endometrial receptivity. The observed estrogenic effect on differential proteome dynamics in Ishikawa cells indicates that the human endometrium is the probable target for serum estradiol levels in COH cycles. The findings are also important for future functional studies with the identified proteins that may influence embryo implantation.

Pembedahan elektif selama fase bleeding siklus menstruasi sering dihindari terkait gangguan koagulasi. Salah satu hormon yang berhubungan dengan proses penyembuhan luka adalah estrogen. Kadar estrogen berfluktuasi sepanjang siklus menstruasi dan berada pada kadar terendah selama fase bleeding. Penelitian eksperimental ex vivo dilakukan pada 16 perempuan berusia 18–40 tahun yang memiliki siklus menstruasi teratur. Darah vena subjek diambil sebanyak 5ml pada fase bleeding dan ovulasi. Kemampuan penyembuhan luka dari masing-masing serum dinilai dengan mengukur proliferasi fibroblas dan deposisi kolagen fibroblas kulit. Ovulasi ditentukan dengan uji pakis saliva, kadar estradiol serum diukur menggunakan Cobas Elecsys®, proliferasi fibroblas menggunakan MTT assay, dan deposisi kolagen dengan sirius red. Hasil penelitian menunjukkan rerata kadar serum estradiol pada fase bleeding dan ovulasi berturut-turut adalah 29,6±10,5pg/dl dan 180,1±164,5pg/dl. Rerata indeks proliferasi fibroblas yang dipajankan pada fase bleeding dan ovulasi adalah 1,09±0,63 dan 1,44±0,66. Rerata densitas optik kolagen fibroblas yang terpajan serum fase bleeding dan ovulasi adalah 0,47±0,2 dan 0,54±0,14. Seluruhnya menunjukkan perbedaan yang bermakna secara statistik (p<0,05). Serum fase bleeding memiliki kemampuan penyembuhan luka yang lebih rendah dibandingkan dengan serum fase ovulasi. Kebijakan untuk tidak melakukan pembedahan elektif selama fase bleeding, selain terkait dengan gangguan pembekuan darah juga terkait dengan proses penyembuhan luka.Kata Kunci:  menstruasi, estradiol, ovulasi, proliferasi fibroblas, deposisi kolagen, penyembuhan luka
