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 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.

Abstract Background: Infertility is an emotional tension which influences the whole aspects of relationships in infertile couples. A main objective of infertility treatments is elevation of pregnancy rate. The present study aimed to examine the effect of collaborative counseling on pregnancy rate in infertile women, undergoing in vitro fertilization in Mashhad, Iran. Methods: In this clinical trial, 60 women with primary infertility were selected from an infertility research center and were randomly allocated into intervention (n=29) and control (n=31) groups. The intervention group received individual counseling, based on the collaborative reproductive healthcare model with collaboration of a midwife, a gynecologist and a clinical psychologist in five sessions during a two-month period. The control group received routine care. Positive pregnancy test was considered as a criterion of treatment success at the end of the study. Data were analyzed using statistical tests including independent samples t-test. Results: There was no significant difference in pregnancy rate between intervention and control groups (P = 0.298). Also, there were no significant differences in follicle and embryo numbers between two groups. However, a significant difference was observed between two groups in terms of oocyte numbers where the intervention group had more oocyte (P = 0.014). Conclusion: Overall the findings indicated that the collaborative infertility counseling did not improve treatment success in infertile women undergoing in vitro fertilization
