Abstract
PURPOSE Are embryo culture conditions, including type of incubator, oxygen tension, and culture media, associated with obstetric or neonatal complications following in vitro fertilization (IVF)? METHODS A systematic search of MEDLINE, EMBASE, and Cochrane Library was performed from January 01, 2008, until October 31, 2021. The studies reporting quantitative data on at least one of the primary outcomes (birthweight and preterm birth) for the exposure group and the control group were included. For oxygen tension, independent meta-analysis was performed using Review Manager, comparing hypoxia/normoxia. For culture media, a network meta-analysis was carried out using R software, allowing the inclusion of articles comparing two or more culture media. RESULTS After reviewing 182 records, 39 full-text articles were assessed for eligibility. A total of 28 studies were kept for review. Meta-analysis about the impact of incubator type on perinatal outcomes could not be carried out because of a limited number of studies. For oxygen tension, three studies were included. The pairwise meta-analysis comparing hypoxia/normoxia did not show any statistical difference for birthweight and gestational age at birth. For culture media, 18 studies were included. The network meta-analysis failed to reveal any significant impact of different culture media on birthweight or preterm birth. CONCLUSION No difference was observed for neonatal outcomes according to the embryo culture conditions evaluated in this review. Further research is needed about the safety of IVF culture conditions as far as future children's health is concerned.

Abstract
PURPOSE Can small RNA derived from embryos in conditioned embryo culture medium (ECM) influence embryo implantation? METHODS We employed small RNA sequencing to investigate the expression profiles of transfer RNA-derived small RNA (tsRNA) and microRNA (miRNA) in ECM from high-quality and low-quality embryos. Quantitative real-time PCR was employed to validate the findings of small RNA sequencing. Additionally, we conducted bioinformatics analysis to predict the potential functions of these small RNAs in embryo implantation. To establish the role of tiRNA-1:35-Leu-TAG-2 in embryonic trophoblast cell adhesion, we utilized co-culture systems involving JAR and Ishikawa cells. RESULTS Our analysis revealed upregulation of nine tsRNAs and four miRNAs in ECM derived from high-quality embryos, whereas 37 tsRNAs and 12 miRNAs exhibited upregulation in ECM from low-quality embryos. The bioinformatics analysis of tsRNA, miRNA, and mRNA pathways indicated that their respective target genes may play pivotal roles in both embryo development and endometrial receptivity. Utilizing tiRNA mimics, we demonstrated that the prominently expressed tiRNA-1:35-Leu-TAG-2 in the low-quality ECM group can be internalized by Ishikawa cells. Notably, transfection of tiRNA-1:35-Leu-TAG-2 into Ishikawa cells reduced the attachment rate of JAR spheroids. CONCLUSION Our investigation uncovers significant variation in the expression profiles of tsRNAs and miRNAs between ECM derived from high- and low-quality embryos. Intriguingly, the release of tiRNA-1:35-Leu-TAG-2 by low-quality embryos detrimentally affects embryo implantation and endometrial receptivity. These findings provide fresh insights into understanding the molecular foundations of embryo-endometrial communication.

Abstract
Cytokine support of embryonic development includes promotion of implantation and protection of blastomeres from cell stress and apoptosis. Correlations between embryo quality and concentrations of specific cytokines in culture media of human embryos have been investigated for many years. The aim of this study was to assess the concentrations of cytokines in preimplantation embryo culture media and to investigate their relationships with embryo quality and in vitro fertilization (IVF) outcomes. Seventy-two samples were obtained from 39 infertile couples undergoing IVF or intracytoplasmic sperm injection treatment between October 2018 and May 2019. Each embryo was cultured separately, and the embryo culture medium was collected 72 h after fertilization. Before embryo transfer on day 3, a morphological evaluation of each embryo was performed. Cytokine concentrations of each culture medium were analyzed for 23 selected cytokines using the Multiplex Cytokine/Chemokine Panel II Assay (Merck Millipore®). The results were categorized into two groups (top-quality and non-top-quality embryos). The median age of the 39 patients was 34 years. Nine of 23 cytokines were quantified and compared between the top-quality embryo group and non-top-quality embryo group. Among the nine cytokines, CCL15, CCL27, and CXCL-12 were significantly elevated in the top-quality embryo group. These results suggested that specific cytokines measured in human embryo culture media can be used to predict embryo quality and IVF outcomes.

Abstract
OBJECTIVE Embryo culture media are important factors in IVF, which can significantly influence clinical outcome of IVF/ICSI cycles. Despite this, it is still not completely clear which formulation is most optimal and whether sequential or continuous media should be favored. MATERIALS AND METHODS This study retrospectively analyzed the outcome of IVF/ICSI cycles with regard to different types of culture media used to culture embryos, namely sequential and two types of single step continuous embryo culture media. RESULTS If the data were combined for both types of single step continuous embryo culture media the only significant difference we observed was the proportion of poor quality embryos on day 3, which was significantly higher (16.9% vs. 22.5%; P = 0.017) in the sequential media. The pregnancy (55.1% vs. 40.5%; P = 0.113) and live birth rates (42.9% vs. 33.8%; P = 0.308) were lower in continuous media, although the difference was not statistically significant. Furthermore, the blastocyst rate (sequential vs. continuous; 47.4% vs. 47.3%; P = 1), and birthweight (3280 ± 630g vs. 3272 ± 575g; P = 0.96) did not significantly differ regardless of the medium used to culture embryos. Additional comparison of each type of continuous medium to sequential media revealed that the difference in the quality of cleavage stage embryos for combined data of both continuous culture media may be derived from the group of cycles were SAGE 1-Step was used to culture embryos. CONCLUSION These results therefore indicate that continuous media can be equivalent to sequential media and could help lower the workload in busy IVF labs without impairing the clinical results. Although, caution is needed because this study is limited by its retrospective design. To confirm the results, especially in terms of live birth rates and perinatal outcome, a prospective study is needed with a higher number of included couples.

Abstract
Leukemia inhibitory factor (LIF) has played a vital role in a series of reproductive events, including follicle growth, embryo growth and differentiation. However, it is unclear whether the level of LIF in embryo culture medium can be used as a marker for clinical pregnancy. In this study, we aimed to investigate whether LIF level in embryo culture medium can act as a predictive marker for pregnancy outcome of in vitro fertilization-embryo transfer (IVF-ET) in infertile women due to tubal problems. A total of 208 infertile women due to tubal problems underwent IVF-ET treatment. The women were divided into two groups according to whether they were clinically pregnant. The level of LIF in the embryo culture medium was measured, and the correlation between LIF level and embryo quality and clinical pregnancy outcome was analyzed. The embryo culture medium was collected on the day of blastocyst transplantation. Compared to non-pregnant group, LIF level in the embryo culture medium on the day of blastocyst transplantation was significantly higher in the pregnant group. LIF level in the embryo culture medium may be used as a non-invasive auxiliary biomarker for predictive clinical pregnancy in infertile women with tubal problems that using single blastocyst transfer method.

Abstract
Background Embryo culture media used for IVF treatment might affect fetal growth and thus birthweight of the newborns. Methods A retrospective study was conducted in South China using data from 2370 singleton neonates born after IVF/ICSI between 2009 and 2012. Two culture media, i.e., either Vitrolife or SAGE were used as embryo culture media during the study period. Neonates’ birthweights were compared between the two embryo culture media groups. Results Among the 2370 singletons, 1755 cases came from fresh cleavage embryo transfer while 615 were from frozen-thawed cleavage embryo transfer. Within the fresh embryo transfer newborns, no statistical difference was observed in either birthweight (mean ± SD: 3196.0 ± 468.9 versus 3168.4 ± 462.0g, p > 0.05) or adjusted birthweight controlled for gestational age and gender (z-score mean ± SD: 0.11 ± 1.02 versus 0.11 ± 0.99 g, P > 0.05) between the Vitrolife (n = 419) and the SAGE group (n = 1336). Likewise within frozen embryo transfer neotates, no statistical difference of the birthweight (3300.6 ± 441.3 vs.3256.0 ± 466.7 g, P > 0.05) and adjusted birthweight (0.30 ± 0.99 g versus 0.29 ± 0.97 g, P > 0.05) was found between the Vitrolife (n = 202) and the SAGE group (n = 413). The sex ratio [OR1.17, 95 % CI (0.94–1.46)/OR1.1, 95 % CI (0.78–1.54)], rate of small for gestational age [OR1.14, 95 % CI (0.82–1.59)/OR1.06, 95 % CI (0.56–2.02)] and large for gestational age [OR1.07, 95 % CI (0.64–1.76)/OR0.98, 95 % CI (0.47–2.02)] in fresh and frozen-thawed subgourps are all comparable respectively between the two culture media. No group differences were found in the rate of low birthweight and macosomia. Multiple linear regression analysis demonstrated that maternal weight, gestational age, frozen-thawed embryo transfer and infant gender were significantly related to neonatal birthweight (P < 0.001). Conclusions It appears that embryos cultured in SAGE or Vitrolife media after fresh or frozen-thawed cleavage embryo transfer did not affect neonate’s birthweight.

Abstract
BACKGROUND Growing concerns about safety of ART on human gametes, embryos, clinical outcomes and long-term health of offspring require improved methods of risk assessment to provide functionally relevant assays for quality control testing and pre-clinical studies prior to clinical implementation. The one-cell mouse embryo assay (MEA) is the most widely used for development and quality testing of human ART products; however, concerns exist due to the insensitivity/variability of this bioassay which lacks standardization and involves subjective analysis by morphology alone rather than functional analysis of the developing embryos. We hypothesized that improvements to MEA by the use of functional molecular biomarkers could enhance sensitivity and improve detection of suboptimal materials/conditions. RESULTS Fresh one-cell transgenic mouse embryos with green fluorescent protein (GFP) expression driven by Pou6f1 or Cdx2 control elements were harvested and cultured to blastocysts in varied test and control conditions to compare assessment by standard morphology alone versus the added dynamic expression of GFP for screening and selection of critical raw materials and detection of suboptimal culture conditions. Transgenic mouse embryos expressing functionally relevant biomarkers of normal early embryo development can be used to monitor the developmental impact of culture conditions. CONCLUSIONS This novel approach provides a superior MEA that is more meaningful and sensitive for detection of embryotoxicity than morphological assessment alone.
