The purpose of this study was to evaluate the effect of atosiban on the outcomes of infertile women undergoing in vitro fertilization (IVF) with difficult embryo transfers (ETs). This randomized double-blind study enrolled 204 infertile women with difficult ETs during IVF treatment between June 2014 and June 2018. According to a computer-generated randomization list, participants were randomized into placebo (n = 102) and atosiban (n = 102) groups. In atosiban group, atosiban with a total dose of 37.5 mg was administered. All of the patients underwent IVF-ET using cryopreserved embryos. The clinical pregnancy rate per cycle and implantation rate per transfer (45.1% and 26.5%) in atosiban group were significantly higher than those of placebo group (15.6% and 9.7%, respectively; P < .05). This study showed that administration of atosiban during ET was extraordinarily effective for patients with difficult transfers.

Abstract Background Total fertilization failure represents a particularly frustrating condition for couples undergoing in vitro fertilization. With the aim of reducing the occurrence of total fertilization failure, intracytoplasmic sperm injection (ICSI) has become the first choice over conventional in vitro fertilization (IVF) procedures although evidence of improved results is still debated and its use in couples without male factor infertility is not recommended. Among the strategies potentially useful to promote the use of conventional IVF, we herein call attention to the late rescue ICSI, which consists in performing ICSI after 18–24 h from conventional insemination on oocytes that show no signs of fertilization. This treatment has however been reported to be associated with a low success rate until recent observations that embryos derived from late rescue ICSI may be transferred after cryopreservation in a frozen-thawed cycle with improved results. The aim of the present study was to assess whether frozen embryos deriving from rescue ICSI performed about 24 h after conventional IVF may represent a valuable option for couples experiencing fertilization failure. Methods A systematic review on the efficacy of late rescue ICSI was performed consulting PUBMED and EMBASE. Results Including twenty-two original studies, we showed that clinical pregnancy rate per embryo transfer and implantation rate obtainable with fresh embryo transfers after rescue ICSI are not satisfactory being equal to 10 and 5%, respectively. The transfer of cryopreserved rescue ICSI embryos seems to offer a substantial improvement of success rates, with pregnancy rate per embryo transfer and implantation rate equal to 36 and 18%, respectively. Coupling rescue ICSI with frozen embryo transfer may ameliorate the clinical pregnancy rate for embryo transfer with an Odds Ratio = 4.7 (95% CI:2.6–8.6). Conclusion Results of the present review support the idea that r-ICSI coupled with frozen embryo transfer may overcome most of the technical and biological issues associated with fresh transfer after late r-ICSI, thus possibly representing an efficient procedure for couples experiencing fertilization failure following conventional IVF cycles.

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 Background The mediating role of coping strategies and its relationship with psychological well-being and quality of life has been considered in the literature. However, there is little research to explore the mechanism of coping strategies on stigma and fertility quality of life (FertiQoL) in infertile women undergoing In Vitro Fertilization Embryo Transfer (IVF-ET). The aim of this study was to examine the mediating effect of coping strategies on the relationship between stigma and fertility quality of life (FertiQoL) in Chinese infertile women undergoing In Vitro Fertilization Embryo Transfer (IVF-ET).Methods: In this cross-sectional study, a total of 768 infertile women undergoing IVF-ET were recruited from Assisted Reproductive Center of Shaanxi Province, China. The personal information, infertility stigma scale, coping strategy scale and FertiQoL scale were measured using a set of questionnaires. The multiple mediator model was performed using AMOS 21.0.Results: The model showed a significant negative direct effect between stigma on FertiQoL (direct effect= -2.375, BC 95% CI= -2.764, -1.987). There were significantly negative indirect effects of stigma on FertiQoL through active-avoidance (indirect effect = -0.706; BC 95% CI = -0.950, -0.497), active-confronting (indirect effect = -0.267; BC 95% CI= -0.414, -0.136) and passive-avoidance (indirect effect= -0.244; BC 95% CI = -0.368, -0.142), respectively. The meaning-based coping played a positive intermediary role (indirect effect=0.105; BC 95% CI = 0.046, 0.190). The model explained 69.4% of the variance in FertiQoL.Conclusion: Active-avoidance coping strategy is the most important mediator factor between stigma and FertiQoL in infertile women undergoing IVF-ET treatment. Meaning-based coping strategy plays a positive mediating role between stigma and FertiQoL.

Background: The purpose of this study was to evaluate the effect of post warming culture period between thawing and transfer of cryopreserved embryos on reproductive outcomes after in vitro fertilization (IVF). Methods: An extensive literature search was performed using PubMed, EmBase, and the Cochrane library from January 2000 to August 2019. A systematic review and meta–analysis of clinical trials was performed in this manuscript. The trials represented patients with embryo transfers of at least one previously cryopreserved good quality embryo. Main outcome measures of the study included clinical pregnancy rate, live birth rate, miscarriage rate, and ectopic pregnancy rate. Results: A total of 5338 trial/abstracts were identified through a literature search. Totally, five studies were included in the systematic review, and three in the final meta–analysis. The studies included 1717 embryo transfers, 605 after short culture, and 1112 after long culture. The clinical pregnancy rate (CPR) was the most consistent outcome reported. The CPR was slightly better after short time culture with a RR of 1.09 (0.95–1.26, 95%CI) but this difference was not statistically significant. The great heterogenicity in the results reported in the included studies made it impossible to compare all planned outcomes. Conclusion: There are no differences in reproductive outcomes if cryopreserved embryos are transferred after overnight culture or after two hours of culture following thawing. Due to small number and the poor quality of trials reported on this topic, the results of this review should be treated with caution.
