Objective It is well known that a dual trigger treatment can improve clinical outcomes of in vitro fertilization(IVF)in high or normal ovarian responders.However,it is not clear whether dual triggering also benefits patients with diminished ovarian reserve(DOR).The aim of this study was to investigate whether a dual trigger treatment of gonadotropin-releasing hormone(GnRH)agonist combined with human chorionic gonadotropin(hCG)for final follicular maturation improves the cumulative live birth rate(CLBR)during the GnRH-antagonist cycle in patients with DOR.Methods This retrospective study included patients with DOR who received a GnRH-antagonist protocol during IVF and intracytoplasmic sperm injection(IVF-ICSI)cycles at Peking University People’s Hospital from January 1,2017 through December 31,2017.Oocyte maturation was triggered by GnRH combined with hCG(n=110)or hCG alone(n=71).Embryos were transferred on the third day after oocyte retrieval or during a subsequent freeze-thaw cycle.Patients were followed up for 3 years.Results The dual trigger treatment did not affect CLBR,which is an overall determinant of the success rate of assisted reproductive technology(ART).Women in the dual trigger group had significantly higher rates of fertilization than those in the hCG group(90.1%vs.83.9%,P=0.040).Conclusion Dual trigger with GnRH agonist and hCG did not improve CLBR in patients with DOR,but did slightly improve fertilization rate,oocyte count,and embryo quality.

The present study aimed to evaluate the clinical outcomes of magnetic-activated cell sorting(MACS)in sperm preparation for male subjects with a sperm DNA fragmentation index(DFI)≥30%.A total of 86 patients who had undergone their first long-term long protocol were selected.The protocol involved in vitro fertilization(IVF)and intracytoplasmic sperm injection(ICSI)cycles,and the patients were divided into the MACS or control groups.The MACS group included sperm samples analyzed with MACS that were combined with density gradient centrifugation(DGC)and the swim-up(SU)technique(n=39),and the control group included sperm samples prepared using standard techniques(DGC and SU;n=41).No differences were noted with regard to basic clinical characteristics,number of oocytes retrieved,normal fertilization rate,cleavage rate,or transplantable embryo rate between the two groups in IVF/ICSI.In addition,the clinical pregnancy and implantation rates of the first embryo transfer cycles indicated no significant differences between the two groups.However,there was a tendency to improve the live birth rate(LBR)of the first embryo transfer cycle(63.2%vs 53.9%)and the cumulative LBR(79.5%vs 70.7%)in the MACS group compared with the control group.Moreover,the number of transferred embryos(mean±standard deviation[s.d.]:1.7±0.7 vs 2.3±1.6)and the transfer number of each retrieved cycle(mean±s.d.:1.2±0.5 vs 1.6±0.8)were significantly lower in the MACS group than those in the control group.Thus,the selection of nonapoptotic spermatozoa by MACS for higher sperm DFI could improve assisted reproductive clinical outcomes.

There were few studies of cumulative live birth rates(CLBRs) based on multicenter reproductive clinical data from the general Chinese population.Here we report a retrospective cohort study,including 14 311 women with17 315 cycles,in three reproductive centers to evaluate two estimated parameters of CLBRs with multiple transfer cycles of in vitro fertilization(IVF)/intracytoplasmic sperm injection(ICSI) in a Chinese population.We found that CLBRs were related to female age and endometrial thickness.By the fourth transfer cycle,the conservative and optimal estimates of CLBRs were 52.95% and 77.30% in women under 30 years of age,and 18.17% and26.51% in those 37 years of age or older,respectively.The two estimates were 44.70% and 63.15% in women with endometrial thickness more than 7 mm,and 32.05% and 46.18% in those with less than 7 mm,respectively.In addition,body mass index(BMI),duration of infertility,and infertility diagnoses may also be related to CLBRs on certain conditions.The findings from this study on CLBRs after multiple transfer cycles of IVF/ICSI treatment on different conditions in the Chinese population should be beneficial to both infertile couples and clinicians.

Background:Empiric therapy for patients with unexplained recurrent pregnancy loss(URPL)is not precise.Some patients will ask for assisted reproductive technology due to secondary infertility or advanced maternal age.The clinical outcomes of URPL patients who have undergonein vitro fertilization-embryo transfer(IVF-ET)require elucidation.The IVF outcome and influencing factors of URPL patients need further study.Methods:A retrospective cohort study was designed,and 312 infertile patients with URPL who had been treated during January 2012 to December 2015 in the Reproduction Center of Peking University Third Hospital were included.By comparing clinical outcomes between these patients and those with tubal factor infertility(TFI),the factors affecting the clinical outcomes of URPL patients were analyzed.Results:The clinical pregnancy rate(35.18%vs.34.52%in fresh ET cycles,P=0.877;34.48%vs.40.27%in frozen-thawed ET cycles,P=0.283)and live birth rate(LBR)in fresh ET cycles(27.67%vs.26.59%,P=0.785)were not significantly different between URPL group and TFI group.URPL group had lower LBR in frozen-thawed ET cycles than that of TFI group(23.56%vs.33.56%,P=0.047),but the cumulative LBRs(34.69%vs.38.26%,P=0.368)were not significantly different between the two groups.The increased endometrial thickness(EMT)on the human chorionic gonadotropin day(odds ratio[OR]:0.848,95%confidence interval[CI]:0.748-0.962,P=0.010)and the increased number of eggs retrieved(OR:0.928,95%CI:0.887-0.970,P=0.001)were protective factors for clinical pregnancy in stimulated cycles.The increased number of eggs retrieved(OR:0.875,95%CI:0.846-0.906,Prate(OR:0.151,95%CI:0.052-0.437,Pcumulative live birth outcome.Conclusion:After matching ages,no significant differences in clinical outcomes were found between the patients with URPL and the patients with TFI.A thicker endometrium and more retrieved oocytes increase the

Frontiers of Medicine 2017年第4期11卷 563-569页

The superiority of the cumulative outcomes of day 5/6 embryo transfer to those of day 2/3 embryo transfer in infertile couples has been debated. This retrospective study included data collected from 1051 patients from July 2011 to June 2014. Multiple maternal baseline covariates were subjected to propensity score matching analysis, and each day 5/6 group woman was matched to one day 2/3 group woman. A systematic meta-analysis was conducted to vaUdate the results. After matching was completed, 217 patients on the day 2/3 group were matched with those on the day 5/6 group, and no significant differences in the baseline characteristics were observed between the two groups. The cumulative pregnancy rate （57.14% vs. 53.46%, OR 1.16, 95% CI 0.79-1.70） and cumulative live birth rate （53.00% vs. 49.77%, OR 1.14, 95% CI 0.78-1.66） of day 5/6 embryo transfers were higher than those of day 2/3 embryo transfers, but this difference was not significant. The mean cycles per live birth and mean days per live birth in the day 5/6 group were significantly lower than those in the day 2/3 group. This study demonstrated that day 5/6 embryo transfer is a more cost-effective and time-efficient policy than day 2/3 embryo transfer to produce a live baby.

This study aimed to investigate whether intracytoplasmic sperm injection（ICSI） shows an advantage over in vitro fertilization（IVF） in non-male factor cycles as the number of oocytes retrieved decreases from four to one.We undertook a retrospective analysis of 1305 IVF/ICSI cycles of non-male factor in which four or fewer oocytes were retrieved.Comparisons were made between conventional IVF（CI） and ICSI when one,two,three or four oocyte（s） were retrieved.Primary outcomes including normal fertilization rate,proportion of embryos per obtained oocyte,cycle cancellation rate,implantation rate,clinical pregnancy rate（PR）,live birth rate（LBR）,cumulative PR and cumulative LBR were evaluated.The results showed that the normal fertilization rate（72.5% vs.50.0%） and the proportion of embryos per obtained oocyte（72.5% vs.55.0%） were significantly increased in one oocyte retrieved cycles in ICSI group as compared with CI group.However,the proportion of embryos per obtained oocyte was markedly decreased in ICSI group when three（52.3% vs.61.3%） or four（56.9% vs.64.0%） oocytes were retrieved.The implantation rates,clinical PRs,LBRs,cumulative PRs and cumulative LBRs in CI group were comparable to those in ICSI group when one,two,three or four oocyte（s） were retrieved.In conclusion,ICSI doesn＇t show advantages over IVF in low oocyte yield cycles of non-male factors,even when only one oocyte was retrieved.Key words

Reproductive and Developmental Medicine 2018年第2期2卷 100-104页

作者： Ting-Yu Zhang Qin-Zhi Bu Chun-Ying Su Reproductive Medical Center First Affiliated Hospital of Zhengzhou UniversityZhengzhou 450052China

Objective:The study was designed to estimate the live birth rate(LBR)and cumulative LBR(CLBR)in patients aged≥40 years undergoing in vitro fertilization or intracytoplasmic sperm injection treatments during their first and multiple ovarian stimulation cycle(s).Methods:A total of 697 advanced women underwent 1,293 treatment cycles,and 973 fresh embryo transfers were performed.The LBR and CLBR were analyzed with respect to an increase in the maternal age by every year.Results:A declining trend in LBR and CLBR of the first cycle was seen with an increase in maternal age.The LBR in women aged 40 years was significantly higher than that in women aged≥44 years(18.39%and 4.39%,respectively);the CLBR in women aged 40 years was also significantly higher than that in women aged 42,43,and≥44 years(22.40%,9.09%,9.09%,and 4.80%,respectively).However,there was no significant difference(P>0.05)in the rate of miscarriage among all groups.For those who underwent multiple cycles,the number of live-born babies decreased rapidly after three ovarian stimulation cycles;the LBR in patients aged 40 years was significantly higher than that in patients aged 42 years and≥44 years(15.24%,5.20%,and 4.49%,respectively),and the CLBR in patients aged 40-41 years was significantly higher than that in patients aged≥42 years.The CLBR in all groups gradually plateaued after three cycles;women aged 40-41 years achieved relatively reasonable CLBR,while the CLBR wasrate quickly decreased,and for women aged≥42 years,the decision to continue after three ovarian stimulation cycles should be made cautiously.
