Introduction. Infertility affects 15-17% of reproductive age couples in our country. In vitro fertilization brought revolution in treatment of this problem, bringing hope to many couples around the world for more than 3 decades. The aim of this paper was to present results and experiences of implementation of this method of treatment at the Clinic of Gynecology and Obstetrics in Nis. Material and Methods. The study included the first 402 women who had undergone in vitro fertilization program at the Clinical Center of Nis. The data were statistically analyzed by basic descriptive methods. The main outcome measures were demographic features, cause of infertility, duration of stimulation, average gonadothropine consumption, number of oocytes per aspiration and embryos transferred, mode of conception as well as clinical pregnancy and aspiration rate. Results. The two main factors were the male infertility and tubal factor inferitily, being 51.61% and 48.39%, respectively. The classical method of in vitro fertilization constituted 72.40% of all cycles, while intra cytoplasmic sperm injection method was used in 27.60% of all cycles. The average number of embryos transferred was 2.75. The cycle cancellation rate was 15.05%. The clinical pregnancy rate per embryo transfer was 35.44%; while the live birth rate per embryo transfer was 26.53%. Discussion and Conclusion. Our success rates are comparable with those in other European countries, where for in vitro fertilization the clinical pregnancy rates per aspiration and per transfer were 29.0 and 32.4%, respectively in the observed period. For intra cytoplasmic sperm injection, the corresponding rates were 29.9 and 33.0%. The main difference from the European average was the average number of transferred embryos and lower percentage rate of intra cytoplasmic sperm injection as a method of conception.

Introduction. Infertility affects 15-17% of reproductive age couples in our country, and 10-15% of couples worldwide. The aim of this paper was to present results and experience gained after the first 1000 cycles of the national In Vitro Fertilization (IVF) program, to offer professional standard of work in our country and to compare it with results obtained in Europe and worldwide. Material and methods. The study prospectively included 1000 women who had undergone national In Vitro Fertilization program from October 2006 until November 2009 at the Department of Gynecology and Obstetrics, Clinical Center of Vojvodina, Novi Sad. Results. The analysis included 1000 in vitro fertilization cycles. Male factor infertility was the leading cause (56.9%) followed by tubal factor (45.9%). The classic method of in vitro fertilization constituted 72.3% of all cycles, while intracytoplasmic sperm injection (ICSI) method was used in 27.7% of all cycles. The average number of embryos transferred was 2.67. The cycle cancellation rate was 14.10% and the aspiration rate was 94.40%. The clinical pregnancy and live birth rate were 33.41% and 26.78% per embryo transfer, respectively. Discussion and conclusion. The results in our study showed that in our setting there are far less intracytoplasmic sperm injection cycles compared with the European average of 66.5% of all fresh cycles, and that we transferred more embryos on average. Our success rates are comparable with those in other European countries where the clinical pregnancy rates per aspiration and per transfer for in vitro fertilization were 29 and 32.4%, respectively in the period of observation. For intracytoplasmic sperm injection, the corresponding rates were 29.9 and 33%.

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 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

Embryo transfer is a critical final step in the in vitro fertilization (IVF) cycle. Much attention has been paid to standardizing the procedures of embryo transfer to improve pregnancy outcome. Objective. To identify the impact of embryo thawing-loading interval (the time interval passing from thawing to loading of frozen embryo into the catheter) on pregnancy outcome. Results. The study was divided into quartiles according to thawing-loading interval in minutes (G I: <60; G II: 60–119; G III: 120–239; G IV: 240 and above). Numerical variables are presented as median and interquartile range, and inter-group differences are compared using the Mann-Whitney U test. Categorical variables are presented as numbers and percentages, and differences are compared using the chi-square test for trend. After adjustment for the age of women, time of previous failed ICSI (Intracytoplasmic sperm injection) trials, number and maturity of transferred embryos, a thawing-loading interval between 60–119 minutes (adjusted odds ratio = 2.222, 95% CI = 1.370 to 3.603, p-value = 0.001) or between 120–239 minutes (adjusted odds ratio = 1.924, 95% CI = 1.172 to 3.161, p-value = 0.010) was independently associated with increased probability of clinical pregnancy compared with a thawing-loading interval of <60 minutes. On the other hand, a thawing-loading interval of ≥240 minutes significantly decreased the probability of clinical pregnancy (adjusted odds ratio = 0.378, 95% CI 0.215 to 0.664, p-value = 0.001). Conclusion. After adjusting for potential confounders, this analysis found that a thawing-loading interval between 60–239 minutes was independently associated with better pregnancy outcomes compared with a thawing-loading interval of <60 minutes. On the other hand, a thawing-loading interval of ≥240 minutes was significantly associated with a worse outcome.
