Blood on the embryo transfer catheter is associated with decreased rates of embryo implantation and clinical pregnancy with the use of in vitro fertilization–embryo transfer

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.

Clinical Pregnancy Rates

IntroductionA trial or mock embryo transfer (ET) may influence pregnancy rates and it performed prior to ET allows the clinician to assess the uterine cavity and the utero-cervical angle. The aim of this study is to compare the consistency of the type of ET in mock ET with real ET.Material & MethodsA retrospective comparative analysis of patients who underwent in vitro fertilization or ICSI cycle from January 2014 to December 2014 in Halim Fertility Center was done. The type of transfer was divided into two groups: ‘easy’ or ‘difficult’. An easy ET was defined as a transfer that occurred without the use of manipulation or other instrumentation and difficult ET was considered when additional instrumentation was required.ResultsFrom the study, 103 patients who underwent Mock-ET, we found 58 patients (56.3%) with easy ET and 45 patients (43.7%) with difficult ET, which with hard catheter ET in 17 patients (16.5%), with osfander assistance in 20 patients (19.4%) and with stylet in 8 patients (7,8%). 58 patients with Easy Mock ET group were entirely easy real ET (100%) and 45 patients with difficult Mock ET group also entirely were difficult real ET (100%). The Statistical analysis shows no significant difference between the mock ET and real ET groups (p>0,05). In easy real ET, clinical pregnancy rates were 32.8% and in difficult real ET, clinical pregnancy rates were 26.7% with no significant difference between the groups (p>0,05).Conclusion:Mock ET prior to the treatment cycle is consistent with real ET.

Abstract Background Several studies had investigated the role of serum Ca-125 in clinical pregnancy of patients undergoing in vitro fertilization (IVF); however, their conclusions had been inconsistent. This study aimed to evaluate the correlation between serum Ca-125 level and clinical pregnancy in IVF.Methods We systematically review the studies in the databases of Mediline OvidSP, EMBASE OvidSP and Cochrane (CENTRAL Central Register of Controlled Trials). Studies on the correlation between serum Ca-125 level and clinical pregnancy in patients underging IVF with or without Intracytoplasmic sperm injection (ICSI) were considered. The pooled standardized mean difference (SMD) with 95% confidence intervals (CIs) was used in the analysis.Results Seven studies involving 558 patients were included. The meta-analysis showed that there was no significant difference in the serum Ca-125 level before embryo transfer (ET) between clinical pregnant group and nonpregnant group (SMD 0.72; 95% CI [0.01, 1.43], P = 0.05, I 2 = 88%), and the same conclusion was also reached in patients without endometriosis (SMD 0.31; 95% CI [-0.53, 1.16], P = 0.47, I 2 = 89%); However, after embryo transfer, the result showed that the Ca-125 level has a small but significantly increase in the clinical pregnant group than in the nonpregnant group (SMD 0.39; 95% CI [0.09, 0.69], P = 0.01, I 2 = 0%).Conclusions Berore ET, there was no significant correlation between serum Ca-125 level and clinical pregnancy in IVF; After ET, the Ca-125 level has a small but significantly increase in the clinical pregnant group than in the nonpregnant group, and it might reflect a successful interaction between the embryo and the endometrium in that time period.

Background: Endometriosis is a chronic condition that is influenced by the hormone estrogen which affects women of childbearing age, and is associated with pelvic pain and infertility. In Vitro Fertilization (IVF) is currently the most efficient assisted reproductive technology and its high success rate is often done for infertility therapy in women associated with endometriosisObjective: The aim of this study is to determine whether postoperative endometriosis affected pregnancy outcomes in patients underwent frozen embryo transfer in IVF / ICSI programs.Method: This Research is done with a retrospective cohort design. The data was taken from medical records, research subjects who met the inclusion and exclusion criteria. The research data was collected, processed and analyzed using SPSS 23. Univariate, bivariate and multivariate data analysis was carried out to determine the effect between variablesResult: There were 458 research subjects in this study. Endometriosis patients were 119 subjects (26%). 57 subjects were categorized as minimum-mild endometriosis (47.9%) and moderate-severe subjects as many as 62 subjects (52.1%). The biochemical pregnancy rate (36.31%) and clinical pregnancy (29.4%) in patients with endometriosis was slightly higher than in non-endometriosis. But statistically it did not affect success rate of achieving biochemical (p = 0.428; RR 0.89; 95% CI: 0.71-1.24) and clinical pregnancy (p = 0.535; RR 0.883; 95% CI: 0.63- 1.22). The rate of miscarriage in postoperative endometriosis patients was higher than non-endometriosis patients (88.6% vs 80.7%) but was not statistically significant (p = 0.294; RR 1.69; 95% CI: 0.61-4.67) . Biochemical and clinical pregnancies were significantly affected by age, infertility, endometrial thickness, embryo age and embryo quality. The incidence of miscarriage was affected by the ovarian stimulation protocol.Conclusion: Endometriosis post operative statistically has no effect on pregnancy outcomes in the IVF / ICSI cycle with frozen embryo transfer compared with another cause of infertility .Keywords:Endometriosis, In Vitro Fertilization, Clinical pregnancy, biochemical pregnancy, miscarriage
