For 99 completed FET cycles, the β-hCG positivity rate was 46.7%, clinical pregnancy rate (CPR) was 41.0%, and live birth rate (LBR) was 36.2%.

Pseudotime analysis divided granulosa cells into before and after the LH surge, and further divided them into two branches, the ovulatory MGCs and the ovulatory CGCs. Interactome analysis was performed to identify the interactions between MGCs and CGCs. Twenty-six interactions were acting from CGCs toward MGCs, involving ovulation and steroidogenesis. Thirty-six interactions were acting from MGCs toward CGCs, involving hyaluronan synthesis. There were 25 bidirectional interactions, involving the EGFR pathway. In addition, we found three novel interactions: Ephrins-Ephs pathway and Wnt-Lrp6 pathway from CGCs to MGCs, associated with steroidogenesis and lipid transport, respectively, and TGF-β-TGFBR1 pathway from MGCs to CGCs, associated with hyaluronan synthesis.Conclusions: MGCs and CGCs interact with each other in the preovulatory follicle after the LH surge, and their interactions have roles in corpus luteum formation, oocyte maturation, and follicle rupture.","PeriodicalId":21116,"journal":{"name":"Reproductive Medicine and Biology","volume":"23 1","pages":"e12564"},"PeriodicalIF":2.7,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10867398/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139741881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Other factors possibly related to blood D-dimer levels were also analyzed.Results: The analysis included 10 patients with OHSS admitted between January 2013 and June 2023. In all patients, blood D-dimer levels increased significantly when they convalesced from OHSS and lost weight. None of the patients showed clinical signs of thrombosis, which was confirmed using imaging tests in 8 of 10 patients. Two patients underwent cell-free and concentrated ascites reinfusion therapy (CART), and their blood D-dimer levels increased dramatically after the procedure.Conclusion: Weight change and CART are associated with blood D-dimer dynamics in OHSS. Our results show that elevated blood D-dimer levels in patients with OHSS do not always represent the presence of thrombosis.

Follicular fluid (FF) is a solo environment of oocyte maturation and may flux into the oviduct. Supplementation of in vitro maturation (IVM) and culture (IVC) medium with extracellular vesicles of FFs supports oocyte maturation and embryonic development. We addressed a hypothesis that miRNA profiles in FFs are crucial background of oocyte maturation and embryonic development.Methods: FFs were collected from the ovaries of individual cows, and the FFs were classified into Good or Poor FF based on the developmental rate to the blastocyst stage of enclosed oocytes. miRNAs associated with the Good FFs were explored using small RNA sequencing. In addition, FFs were classified using the concentration of Good-FF-associated miRNAs. These classified FFs or miRNA were added to the IVM or IVC mediums.Results: Supplementation of IVM and IVC medium with Good FF improved embryonic development. Good FFs contained miR-151-3p and miR-425-5p at a high concentration compared with those in Poor FFs. FFs selected by the concentration of miR-151-3p and miR-425-5p improved oocyte maturation and embryonic development.
