RESUMO

OBJECTIVE: The aim of this meta-analysis is to explore the beneficial role of granulocyte colony-stimulating factor (G-CSF) on infertile women under artificial reproduction technology treatment. METHOD: Medline, Embase and ISI Web of Science databases were searched to identify relevant randomized control trials. Studies before July, 2017 were included for primary screening. Meta-analysis of the total and subgroup patients was conducted, and relative risks (RRs) and their 95% confidence intervals (95% CI) were calculated by a fixed-effect model if no heterogeneity (evaluated as I2 statistic) existed. Otherwise, a random-effects model was adopted. Subgroup analysis was performed by administrating route or clinical indication. Egger test and influence analysis were conducted to evaluate the publication bias and study power, respectively. RESULTS: The final selection enrolled 10 RCTs, involving 1016 IVF-ET cycles (521 distributed to the G-CSF group and 495 to the control). Compared with control group, G-CSF administration could significantly improve clinical pregnancy rate (CPR, RR 1.89, 95% CI 1.53-2.33), while it had no beneficial effect on embryo implantation rate (IR, RR 1.84, 95% CI 0.84-4.03). The subgroup analysis by administration route showed that both uterine infusion and subcutaneous injection can produce a substantial increase in CPR, with the pooled RRs (95% CI) 1.46 (1.04-2.05) and 2.23 (1.68-2.95), respectively. Nevertheless, most of included RCTs dealt with the RIF subjects, and the pooled analysis of this data showed a higher PR and IR in G-CSF group as compared to that in the control, with the RRs (95% CI) 2.07 (1.64-2.61) and 1.52 (1.08-2.14), respectively. Egger regression test did not demonstrate any significance for the publication bias. CONCLUSION: G-CSF administration has a beneficial role on the clinical outcome after embryo transfer by both routes of local infusion and systematic administration, especially for the cases with RIF. Further RCTs are needed to investigate the role of G-CSF in thin endometrium patients.

RESUMO

OBJECTIVE: To compare the efficacy of different time interval in the prevention of adhesion reformation after hysteroscopic adhesiolysis for moderate-severe Asherman's syndrome. METHODS: A total of 125 women with moderate-severe Asherman's syndrome undergoing hysteroscopic division of intrauterine adhesion were enrolled into this retrospective cohort study. All patients underwent second-look hysteroscopy after a certain period of the first hysteroscopic adhesiolysis, and the operation would be performed again if any adhesion existed. According to the different time interval of hysteroscopy examination, they were divided into 3 groups: A: < 1 month (n = 50), B:1-2 months (n = 39), C >2 months (n = 36). The effect of hysteroscopic adhesiolysis was evaluated by American Fertility Society (AFS) score. RESULTS: The AFS score decreased significantly after hysteroscopic adhesiolysis in each group and the normal uterine rate was up to 64.8%. The median of decreased AFS score and normal uterine rate were as follows:group A:7 point and 78%, group B:7 point and 66.7%, group C:5 point and 44.4%. And groups A and B achieved significantly (P < 0.01) greater reductions in the adhesion score than that of group C. The median time of recovery to normal uterine cavity were 1.64, 2.75 and 5.26 months in each group and great differences existed among them (P < 0.01). CONCLUSION: The time interval of second-look hysteroscopy less than 1 month offers a better prognosis in the prevention of adhesion reformation for moderate-severe Asherman's syndrome.

RESUMO

BACKGROUND: Endometriosis affects natural fertility through various approaches, and in vitro fertilization (IVF) is a good treatment. But the IVF result of endometriosis patients is still under debate. We investigated the effect of endometriosis on IVF by analyzing the data from a single reproductive center. METHODS: A retrospective, database-searched cohort study was performed. Relevant information was collected from the electronic records of women who underwent IVF/intracytoplasmic sperm injection between January 2006 and December 2010 in the Assisted Reproductive Unit of Sir Run Run Shaw Hospital. Patients with endometriosis were enrolled the study group. The rest of the women formed the control group. The main outcome was the clinical pregnancy rate. Secondary outcomes were oocytes retrieved number, fertilization rate, high-quality embryo rate, number of high-quality embryo for embryo transplantation, and implantation embryo/high-quality embryo ratio (IE/HQE ratio). Comparisons were performed by the c(2)-test and independent t-test. RESULTS: The endometriosis group (n = 177) had a markedly lower oocytes retrieved number, fertilization rate, implantation rate, and clinical pregnancy rate (7.6 ± 5.1, 63.6%, 27.7%, and 45.2%, respectively) compared with the non-endometriosis group (n = 4267; 11.8 ± 7.3, 68.4%, 36.2%, and 55.2%, respectively). Stratified analysis showed that this difference was found in the subgroup younger than 35-years old, while only fertilization rate and implantation rate were different in the elder subgroup. The ratio of high-quality embryos transferred is lower in endometriosis group (53.7% vs. 71.8%, P < 0.05), but there is no difference in IE/HQE ratio between two groups. There is no significant difference in fertilization rate, implantation rate, and clinical pregnancy rate between mild and severe endometriosis patients. CONCLUSIONS: Endometriosis patients suffer a decreasing IVF pregnancy rates mainly caused by reducing oocytes number and fertilization rate, regardless of the severity of the disease. Appropriate intracytoplasmic sperm injection manipulation might improve the outcomes of IVF.

RESUMO

OBJECTIVE: To analyze the risk factors for triplet pregnancy after a simultaneous transfer of triplicate embryos. METHODS: The investigators carried out a retrospective analysis of 769 cycles in which three embryos were transferred in one treatment cycle, including 298 fresh embryo transfer (ET) cycles and 471 frozen-thawed ET (FET) cycles. The impact of patient age and the number of good embryos transferred on the rates of clinical pregnancy and triplet pregnancy was studied according to different cycle types. RESULTS: (1) The rates of clinical and triplet pregnancy were significantly higher in the FET group (P < 0.05) than those in the fresh ET group; (2) all patients with a triplet pregnancy in the fresh ET group (n = 6) were younger than 35 years old (P < 0.01). There was no significant difference between the subgroups in the FET cycle according to patient age (P > 0.05); (3) when none, 1, 2 or 3 good embryos were transferred in the fresh ET cycle, the clinical pregnancy rates were 28.3%, 46.7%, 50.6% and 58.7% and the triplet pregnancy rates 0, 2.3%, 4.7% and 6.8% respectively. A similar clinical pregnancy rate (P > 0.05) and a significantly lower triplet pregnancy rate (P < 0.05) were observed when 1 good embryo was transferred versus 2 good embryos (P < 0.05). When 0, 1, 2 or 3 good embryos were transferred in the FET cycle, the clinical pregnancy rates were 38.9%, 54.8%, 59.7%, 63.9% and the triplet pregnancy rates 0, 5.0%, 13.8%, 15.8% respectively. A similar clinical pregnancy rate (P > 0.05) and a significantly lower triplet pregnancy rate (P < 0.05) were observed when 1 good embryo was transferred versus two good embryos (P < 0.05). All triplet pregnancies occurred in cycles in which more than 1 good embryo was transferred (P < 0.05). CONCLUSION: The patients have more triplet pregnancies in the FET cycle than in the fresh ET cycle. In the FET cycle, the patient age is irrelevant. It is recommended that no more than 2 embryos should be transferred. Selective single blastocyst embryo transfer is preferable if there are more than 2 good embryos available for transfer. No more than 2 embryos should be transferred in the fresh ET cycle if good embryos are available and a patient is under 35 years old.

RESUMO

OBJECTIVE: To report two successful pregnancies after frozen-thawed ET in discontinued hormone replacement treatment cycles. DESIGN: Case report. SETTING: University hospital. PATIENT(S): Two infertile patients. INTERVENTION(S): Hormone replacement treatment for endometrial preparation and frozen-thawed ET. MAIN OUTCOME MEASURE(S): Ovarian ultrasonography, serial hormone measurements of serum E2 and P, successful pregnancy, and follow-up visit. RESULT(S): One patient discontinued both E2 and P support 2 weeks after ET. The other discontinued estrogen support on the day preceding ET. No spontaneous follicle development was observed by ultrasonography, and no increase in serum P concentration was observed. Both patients became pregnant and achieved deliveries. CONCLUSION(S): These two cases show that maintenance of pregnancy is possible without early hormone support in hormone replacement treatment cycles.

RESUMO

OBJECTIVE: To investigate the effects of mouse preimplantation embryos on the expressions of DNA methyltransferase 1(Dnmt1) of mouse oviduct epithelial cells. METHODS: The histological location of Dnmt1 protein was detected by immunohistochemical staining and the expression levels of Dnmt1 mRNA and protein in mouse oviduct were assayed by real-time reverse transcription-PCR(RT-PCR) and Western blotting in both pregnant and pseudopregnant mice at the 2-cell, 4-cell and 8-cell stages. RESULTS: The expressions of Dnmt1 protein were mainly located in the epithelial cells of mouse oviduct. It was found that during all three stages, the expression levels of Dnmt1 mRNA in the epithelial cells of the pregnant mice were significantly lower than those in the pseudopregnant mice (P< 0.05), and the level of Dnmt1 protein expression in the pregnant mice was significantly decreased as compared with that in pseudopregnant mice at the 4-cell stage. CONCLUSION: Expressions of both Dnmt1 mRNA and protein in the epithelial cells of mouse oviduct could be regulated by mouse preimplantation embryos, which might play an important role in the expression changes of some genes in oviduct epithelial cells during the preimplantation period.
