We conducted a randomized trial to compare the effect of 15 min versus 30 min of bed rest after IUI on pregnancy rate. A total of 204 couples were recruited from May 2021 to December 2021 and randomized to remain in the supine position for either 15 or 30 min after the procedure. The outcomes were the clinical pregnancy rate and comfort level after IUI. Ultimately, 198 couples were included in the analysis. The 15-min immobilization group consisted of 100 couples (226 cycles), and the 30-min immobilization group consisted of 98 couples (225 cycles). The clinical pregnancy rate per couple in the 15-min immobilization group (26 of 100) was not different from that in the 30-min immobilization group (23 of 98). With the use of discrete-time survival analysis, the cumulative probability of clinical pregnancy also showed no difference between these two groups. Based on the literature and on our study, the possible beneficial effect of 30-min immobilization after IUI is at least questionable, and a shorter time could be implemented depending on the results of a systematic review and the individual patient data from the currently executed trials.","PeriodicalId":13006,"journal":{"name":"Human Fertility","volume":" ","pages":"1354-1360"},"PeriodicalIF":1.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9516067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The endometrial preparation during frozen embryo transfer (FET) was performed in the natural cycle (NC) with timing based on monitoring of the naturally occurring luteinizing hormone (LH) peak or in human chorionic gonadotropin (hCG)-triggered modified natural cycles (MNC), artificial cycle (AC) with hormone replacement therapy cycle and cycle with ovulation induction (OI). A retrospective cohort study was conducted between 2018 and 2020. Pregnancy, perinatal complications and neonatal outcomes were compared among patients treated during AC or MNC or OI protocols. After adjusting for the effect of gravidity, parity, pre-pregnancy body mass index (BMI) and number of miscarriages, the AC group had higher but not significantly different rates of gestational hypertension, preeclampsia and intrahepatic cholestasis of pregnancy (ICP) than women in OI and MNC groups. Significant differences were observed in the rates of placental adherence (15.30% in AC vs. 9.24% in MNC, p = 0.004) and postpartum haemorrhage (PPH) (24.33% in AC vs. 13.07% in OI, p = 0.003, 24.33% in AC vs. 16.24% in MNC, p = 0.002) among the three groups. In singletons, significant differences were observed in the rates of placental adherence (14.09% in AC vs. 8.57% in MNC, p = 0.002), AC and MNC groups had higher risk of PPH compared with OI group (18.36% in AC vs. 12.38% in MNC, p = 0.042 and 7.69% in OI vs. 18.36% in AC, p = 0.013). Neonatal outcomes were similar among the three groups except risk of small for date infants (0.35% in AC vs. 1.44% in MNC, p = 0.008).

Retrieved eggs from their partners were divided into two groups in which they were injected with different sorted sperm. The fertilization rate and embryonic development were evaluated. While sperm's progressive motility and morphology significantly improved, there was a substantial decline in DFI following MACS-DGC. Fertilization rates were almost the same between the groups, and the latter resulted in remarkably more top-quality embryos and more blastocysts. PLCz1 expression was considerably higher in the MACS-DGC group.
