Abstract Background: MicroRNAs (miRNAs) are a class of noncoding small RNAs that play important roles in many physiological processes by regulating gene expression. Previous studies have shown that the expression levels of total miRNAs increase during mouse embryonic development, and some miRNAs control the regulatory network in development progression. However, few studies have focused on the effects of miRNAs on early human embryonic development. The relationship between miRNAs and early human embryogenesis is still unknown. Results:In this study, RNA-seq data collected from sperm samples from 102 patients with a normal sperm index but treated with assisted reproductive technology (ART) were analyzed for the relationships between differentially expressed small RNAs and the fertilization rate (FR), blastocyst rate and high-quality embryo rate (HQER). The sperm samples with high hsa-mir-191 expression had a higher FR, effective embryo rate (EER) and HQER. hsa-mir-191 was used as a single indicator to predict the HQER. The receiver operating characteristic (ROC) curve had an area under the ROC curve (AUC) of 0.686. We also found that hsa-mir-191 expression is correlated with an abnormal sperm rate (cor = 0.29, p< 0.01). We also evaluated the relationship between hsa-mir-34c and early human embryo development in these 102 sperm samples and obtained negative results. Conclusions: These findings suggest that high hsa-mir-191-5p expression in sperm is associated with early human embryonic quality and that hsa-mir-191-5p could be used as a potential marker to screen high-quality sperm to improve the success rates of in vitro fertilization (IVF).

Abstract Background: MicroRNAs(miRNAs) are a class of non-coding small RNAs, which play important roles in many physiological processes by regulating gene expression. Previously studies show that the expression level of total miRNAs increased during the progression of mouse embryonic development, and some miRNAs control the regulatory network in the development progression. However, there are few studies focused on effects of miRNA on the early human embryonic development. The relationship of between miRNAs and early human embryogenesis is still unknown. Results In this study, 102 male sperm samples that were treated with assisted reproductive technology but with normal sperm index were collected for small RNA sequencing, and the relationships between differentially expressed small RNA and fertilization rate, blastocyst rate and high-quality embryo rate were analyzed. The results showed that the sperm samples with high expression of hsa-mir-191 had higher fertilization rate, blastocyst rate and high-quality embryo rate. Using hsa-mir-191 as a single indicator to predict high-quality embryo rate, the ROC curve has an AUC of 0.686. At the same time, we also found that the expression of hsa-mir-191 has a certain correlation with sperm abnormality rate (cor = 0.29, p< 0.01). In addition, we also evaluated the relationship between hsa-mir-34c and human early embryo development in these 102 sperm samples, and obtained negative results. Conclusions These findings suggest that higher hsa-mir-191-5p expression with better human early embryonic development, and indicate that the hsa-mir-191-5p could be a potential marker to access the quality of IVF.

Abstract Background: Melatonin (MT), a powerful antioxidant, can effectively ameliorate the in vitro development of animal embryos, but few studies have been performed on human embryos. Therefore, we investigated whether the application of MT in embryo cultures can improve embryonic development and clinical outcomes of patients with repeated cycles after failed in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles.Methods: Human immature oocytes from controlled ovarian hyperstimulation cycles were collected for in vitro maturation culture and ICSI fertilization. The obtained embryos were cultured in vitro in medium containing 0, 10-11, 10-9, 10-7 or 10-5 M MT, and 10-9 M was determined to be the optimal concentration. Subsequently, 140 patients who experienced failed IVF/ICSI cycles underwent 140 cycles of embryo culture in vitro with medium containing 10-9 M MT. High-quality blastocysts were collected and cryopreserved for three months before vitrified-warmed embryo transfer. These culture cycles served as the experimental (10-9 M) group. The control (0 M) group comprised previous failed cycles. The patients were further divided into subgroups of 1, 2 or ≥3 failed cycles. The fertilization and embryo development statuses were compared.Results: The fertilization, cleavage, high-quality embryo, blastocyst, and high-quality blastocyst rates of the 10-9 M group were significantly higher than those of the 0 M group (87.7% vs. 83.6%, p <0.01; 94.1% vs. 90.5%, p <0.01; 58.3% vs. 43.8%, 51.1% vs. 41.8%, 43.4% vs. 22.9%, all p <0.0001). To date, a total of 50 vitrified-warmed cycle transfers were performed in the 10-9 M group and the implantation rate, biochemical pregnancy rate and clinical pregnancy rate were significantly higher than those in the 0 M group (65.6% vs. 9.7%, p <0.0001; 64.0% vs. 12.5%, p <0.0001; 40.0% vs. 11.7%, p <0.0001). Two healthy infants were delivered successfully and the other 18 women who achieved clinical pregnancy also had good examination indexes.Conclusion: The application of MT to embryo cultures in vitro improved embryonic development in patients with repeated cycles after failed IVF/ICSI cycles and had good clinical outcomes. The optimal concentration of MT was 10-9 M.Trial registration: Name in the registry: Effect of melatonin on the clinical outcome of patients with repeated cycles after failed cycles of in vitro fertilization and intracytoplasmic sperm injection; registration number: ChiCTR2100045552; date of registration: April 19, 2021(retrospectively registered); URL of trial registry record: www.medresman.org.cn.

Abstract Background: In this study, we compared the in vitro embryo development, embryo transfer outcome and the offspring outcome in the in vitro fertilization-embryo transfer (IVF-ET) between dry culture (DC) and humid culture (HC). Methods: Our study was divided into two parts. Firstly, we determined the fertilization rate, cleavage rate and high-quality embryo rate from 21 cycles in the DC group (N=262 oocytes) and HC group (N=263 oocytes). Secondly, we determined the embryo transfer outcome and the offspring outcome in DC group (N=184 cycles) and HC group (N=136 cycles). Results: Compared with the HC group, significant increase was observed in the high-quality embryo rate (66.1.2% vs. 55.3%, p=0.037) and implantation rate (49.8% vs. 40.6%, p=0.027) in the DC group. No statistical differences were observed in the pregnant outcome and birth defect of the offspring (p>0.05). Compared with HC, DC was associated with a higher high-quality embryo rate and a higher implantation rate after embryo transfer. Conclusions: No statistical differences were noticed in the offspring conditions between the two culture modes. Taken together, DC may serve as a promising method for IVF-ET.

Abstract BackgroundThe outcome of in vitro fertilization-embryo transfer is often determined according to follicles and estradiol levels following gonadotropin stimulation. However, there is no accurate indicator to predict pregnancy outcome, and it has not been determined how to choose subsequent drugs and dosage based on the ovarian response. This study aimed to make timely adjustments to follow-up medication to improve clinical outcomes based on the potential value of estradiol growth rate. MethodsSerum estradiol levels were measured on the day of gonadotrophin treatment (Gn0), four days later (Gn4), seven days later (Gn7), and on the trigger day (HCG). The ratio was used to determine the increase in estradiol levels. According to the ratio of estradiol increase, the patients were divided into four groups: group A1 (Gn4/Gn0≤6.44), group A2 (6.44˂Gn4/Gn0≤10.62), group A3 (10.62˂Gn4/Gn0 ≤21.33), and group A4 (Gn4/Gn0>21.33); group B1 (Gn7/Gn4≤2.39), group B2 (2.39˂Gn7/Gn4≤3.03), group B3 (3.03˂Gn7/Gn4≤3.84), and group B4 (Gn7/Gn4>3.84). We analyzed and compared the relationship between data in each group and pregnancy outcome. ResultsIn the statistical analysis, the estradiol levels of Gn4 (P = 0.029, P = 0.042), Gn7 (P< 0.001, P = 0.001), and HCG (P< 0.001, P = 0.002), as well as the ratios of Gn4/Gn0 (P = 0.004, P = 0.006), Gn7/Gn4 (P = 0.001, P = 0.002), and HCG/Gn0 (P< 0.001, P< 0.001) both had clinical guiding significance, and the lower one significantly reduced the pregnancy rate. The outcomes were positively linked to groups A (P = 0.040, P = 0.041) and B (P = 0.015, P = 0.017). The logistical regression analysis revealed that group A1 (OR = 0.440 [0.223–0.865]; P = 0.017, OR = 0.368 [0.169–0.804]; P = 0.012) and B1 (OR = 0.261 [0.126–0.541]; P< 0.001, OR = 0.299 [0.142–0.629]; P = 0.001) had opposite influence on outcomes. ConclusionMaintaining a serum estradiol increase ratio at least above 2.39 on Gn7/Gn4 may result in a higher pregnancy rate. When estradiol growth is not ideal, gonadotrophin dosage should be adjusted appropriately to ensure the desired outcome.
