Analysis of Factors Influencing the Cumulative Pregnancy Outcome of In Vitro Fertilization-Embryo Transfer in Women Aged 35 Years and Older with Normal Ovarian Reserve

Background:To investigate the factors associating with the cumulative clinical pregnancy outcome of in vitro fertilization-embryo transfer(IVF-ET)in women aged 35 years and older with normal ovarian reserve.Methods:A total of 358 patients undergoing IVF-ET at the Department of Reproductive Medicine,the First Affiliated Hospital of Xinjiang Medical University between January 2014 and June 2016 were analyzed by the Kaplan-Meier method and Cox proportional hazards model.Results:The probability of pregnancy in women 35-37 years of age and 38-40 years of age was 75.9%(95%confidence interval[CI]:75.1%-76.7%)and 66.9%(95%CI:65.6%-68.2%),respectively,and it was 37.8%(95%CI:34.7%-41.1%)in women aged 40 years and older.Univariate analysis(hazard ratio[HR]:2.50,95%CI:1.647-3.774)and multivariate analysis(HR:2.17,95%CI:1.427-3.268)showed a correlation between the number of retrieved oocytes and successful pregnancy.Conclusions:The number of retrieved oocytes plays a key role in the pregnancy outcome of women aged 35 years and older with normal ovarian reserve.We recommend the number of retrieved oocytes be increased for women aged 35 years and older with normal ovarian reserve.

Relationship between lower number of oocytes retrieved and clinical outcomes of in vitro fertilization-embryo transfer

Objective:To explore the clinical outcomes of the infertile women with retrieved oocytes less than or equal to 5 undergoing in vitro fertilization-embryo transfer（IVF-ET） or intracytoplasmic sperm injection（1CSI）. Methods:The clinical data of 216 embryo transfer cycles with retrieved oocytes less than or equal to 5 during the procedure of IVF/ICSI in Reproductive Medicine Center of the 105th Hospital of PLA from Jul.2008 to Dec.2011 were analyze retrospectively.All the patients were divided into group A（< 35 years）,group B（35-39 years） and group C（≥40 years） according to the ages,and 409 IVF/ICSI cycles with patients’ age less than 35 years old and 6-15 retrieved oocytes in the same period were served as controlled group.Then the patients≥35 years were subdivided into gonadotropin-releasing hormone agonist（GnRH-a） long protocol group,GnRH-a short group and GnRH antagonist group according to the protocols of controlled ovarian hyperstimulation（COH）.The clinical date and the outcomes were analyzed and compared among all groups. Results:There were significantly differences in clinical pregnancy rate（38.3%vs.19.4%） and early abortion rate（16.1%vs.50.0%） between group A and group C（P<0.05）,and there were no significant differences in clinical pregnancy rate（38.3%vs.41.6%）and early abortion rate（16.1%vs.10.0%） between group A and control group（P>0.05）.There were no significant differences in clinical pregnancy rates（29.01%vs.26.1%vs.25.9%） and early abortion rates（33.3%vs.33.3%vs.40.0%） among GnRH-a long protocol group,GnRH-a short group and GnRH antagonist group（P>0.05）. Conclusions:Relatively satisfactory clinical outcomes of IVF/ICSI would still be got for the patients <35 years with retrieved oocytes less than or equal to 5,but whatever COH protocols such as GnRH-a long protocol,GnRH-a short and GnRH antagonist could not improve the outcomes of IVF/ICSI for the patients aged≥35 with retrieved oocytes less than or equal to 5.

Untreated Prior Pulmonary Tuberculosis Adversely Affects Pregnancy Outcomes in Infertile Women Undergoing in vitro Fertilization and Embryo Transfer: A Large Retrospective Cohort Study

Objective Prior pulmonary tuberculosis(PTB) on chest X-ray(CXR) was commonly found in infertile patients receiving examinations before in vitro fertilization and embryo transfer(IVF-ET). It was unclear whether untreated PTB would affect pregnancy outcomes after IVF-ET.Method We conducted a retrospective cohort study of 14,254 infertile patients who had received IVFET at Peking University Third Hospital in 2017. Prior PTB was defined as the presence of signs suggestive of old or inactive PTB on CXR, with or without a clinical TB history. Patients who had prior PTB on CXR but had not received a clinical diagnosis and anti-TB therapy were included for analysis. Live birth,clinical pregnancy, and miscarriage rates were compared between the untreated PTB and non-PTB groups.Results The untreated PTB group had significantly lower clinical pregnancy(31.7% vs. 38.1%) and live birth(23.8% vs. 30.6%) rates than the non-PTB group(both P < 0.001). Multivariate analysis revealed that untreated PTB was a risk factor for decreased live birth rate [odds ratio(OR), 0.80;95% confidence interval(CI), 0.66–0.98;P = 0.028] in all patients and for increased miscarriage(OR, 4.19;95% CI,1.69–10.39;P = 0.002) and decreased live birth(OR, 0.45;95% CI, 0.24–0.83;P = 0.011) rates in patients with unexplained infertility.Conclusions Untreated PTB was associated with adverse pregnancy outcomes after IVF-ET, especially in patients with unexplained infertility, highlighting the clinical significance of PTB in this specific patient population.

Effect of different fertilization time after human chorionic gonadotropin injection on fertilization outcome of patients in vitro fertilizationembryo transfer

Objective:To explore the effect of different fertilization time after human chorionic gonadotropin(HCG)injection on the outcome of fertilization in vitro fertilization-embryo transfer(IVF-ET).Methods:One thousand one hundred and forty IVF-ET cycles from January 2016 to August 2018 were analyzed retrospectively.According to the different fertilization time after injection of HCG divided into four groups:Group A(38.0 h~39.0 h),Group B(39.1 h~40.0 h),Group C(40.1 h~41.0 h),and Group D(41.1 h~42.0 h).The normal fertilization rate,the normal cleavage rate,the embryo utilization rate,the high-quality embryo rate,the clinical pregnancy rate,the implantation rate,and the spontaneous abortion rate were analyzed among the groups.Then we investigated the effect of different promotion methods on the outcome of fertilization during the optimal fertilization time.Results:There was no significant difference in 2PN cleavage rate,available embryo rate,clinical pregnancy rate,implantation rate and abortion rate among the four groups(P>0.05).The high-quality embryo rate in Group D(44.6%)was the highest,and was significantly different among the four groups(P<0.05).The normal fertilization rate in Group D(71.6%)was the highest,and was significantly different among the four groups(P<0.05).The normal fertilization rate(78.1%)of antagonist group was significantly higher than other groups(P<0.05).Conclusion:The different fertilization time after HCG injection have effects on high-quality embryo rate and normal fertilization rate of patients in IVF-ET.The appropriate fertilization time of patients in IVF-ET was 41 h~42 h after HCG injection in our reproductive center,improved the clinical pregnancy rate and reduced the early abortion rate.The GnRH-ant protocol is superior to other protocol in IVF-ET.

Mesenteric vein thrombosis following impregnation via in vitro fertilization-embryo transfer

Pregnancy is an acquired hypercoagulable state. Most patients with thrombosis that develops during pregnancy present with deep vein leg thrombosis and/or pulmonary embolism, whereas the development of mesenteric vein thrombosis(MVT) in pregnant patients is rare. We report a case of MVT in a 34-year-old woman who had achieved pregnancy via in vitro fertilization-embryo transfer(IVFET). At 7 wk of gestation, the patient was referred to us due to abdominal pain accompanied by vomiting and hematochezia, and she was diagnosed with superior MVT. Following resection of the gangrenous portion of the small intestine, anticoagulation therapy with unfractionated heparin and thrombolysis therapy via a catheter placed in the superior mesenteric artery were performed, and the patient underwent an artificial abortion. Oral estrogen had been administered for hormone replacement as part of the IVF-ET procedure, and additional precipitating factors related to thrombosis were not found. Pregnancy itself, in addition to the administered estrogen, may have caused MVT in this case. We believe that MVT should be included in the differential diagnosis of a pregnant patient who presents with an acute abdomen.

Letter to the editor“regarding case report of chronic cornual ectopic pregnancy presenting as large cornual mass after in vitro fertilization-embryo transfer”

We read the Yang et al,published case report in Laparoscopic,Endoscopic and Robotic Surgery.2019.https://doi.org/10.1016/j.lers.2019.09.001,with great interest.Yang et al,in the introduction mentioned that the cornual ectopic pregnancy is defined as a pregnancy that is abnormally located in the proximal portion of the fallopian tube,lying within the muscular wall of the uterus.

Effects of Acupuncture on Endometrium and Pregnancy Outcomes in Patients with Polycystic Ovarian Syndrome Undergoing in vitro Fertilization-Embryo Transfer:A Randomized Clinical Trial

Objective:To observe the effect of acupuncture on endometrium and pregnancy outcomes in patients with polycystic ovary syndrome(PCOS)infertility undergoing in vitro fertilization-embryo transfer(IVF-ET).Methods:Eighty-three patients were randomly assigned to observation group(40 cases)and control group(43 cases)according to the random numbers generated by SPSS software.The patients of the two groups received GnRH agonist long protocol as a routine treatment.In the observation group,acupuncture was given at two acupoint groups for 30 min once every other day.Group 1 included Guanyuan(CV 4),Qihai(CV 6),Zhongji(CV 3),bilateral acupoints Zigong(EX-CA1).Group 2 included Mingmen(GV 4),Yaoyangguan(GV 3),bilateral Shenshu(BL 23)and Ciliao(BL 32).The two groups of acupoints were used alternately.The whole needling process was performed at the time of ovulation induction until the transplantation day and consisted of3 courses,while the control group did not receive acupuncture interventions.The Gn dosage and Gn stimulation time,endometrial thickness and type(A,B,and C),serum oestradiol(E2)and progesterone(P)levels on the day of injection of human chorionic gonadotropin(hCG),clinical pregnancy rate,as well as live birth rate were observed.Adverse reactions were also be recorded.All patients were followed up for the pregnant rate 14 days after IVF-ET and live birth rate after pregnancy.All adverse reactions(AEs)of acupuncture were recorded during the trial.Ressults:The Gn dosage and Gn stimulation time in the observation group were lower in the observation group than in the control group(P<0.01).The proportion of type A endometrium in the observation group were higher than that in the control group(P<0.05).The serum E2 and P levels on the day of hCG injection was lower and the clinical pregnancy rate was higher in the observation group compared to those in the control group(P<0.05).There was no serious AEs during this trial.Conclusion:Acupuncture can improve the proportion of type A endometrium,regulate the levelse of serum Eand P on the day of hCG injection,and improve the pregnancy rate in patients with PCOS infertility undergoing IVF-ET.

Effects of Zishen Yutai Pills on in vitro Fertilization-Embryo Transfer Outcomes in Patients with Diminished Ovarian Reserve:A Prospective,Open-Labeled,Randomized and Controlled Study

Objective:To explore the effects of Zishen Yutai Pills(ZYPs)on the quality of oocytes and embryos,as well as pregnancy outcomes in patients with diminished ovarian reserve(DOR)receiving in vitro fertilizationembryo transfer(IVF-ET).The possible mechanisms,involving the regulation of bone morphogenetic protein 15(BMP15)and growth differentiation factor 9(GDF9),were also investigated.Methods:A total of 120 patients with DOR who underwent their IVF-ET cycle were randomly allocated to 2 groups in a 1:1 ratio.The patients in the treatment group(60 cases)received ZYPs from the mid-luteal phase of the former menstrual cycle by using gonadotropin-releasing hormone(Gn RH)antagonist protocol.The patients in the control group(60 cases)received the same protocol but without ZYPs.The primary outcomes were the number of oocytes retrieved and high-quality embryos.Secondary outcomes included other oocyte or embryo indices as well as pregnancy outcomes.Adverse events were assessed by comparison of the incidence of ectopic pregnancy,pregnancy complications,pregnancy loss,and preterm birth.Contents of BMP15 and GDF9 in the follicle fluids(FF)were also quantified with enzymelinked immunosorbent assay.Results:Compared with the control group,the numbers of oocytes retrieved and high-quality embryos were significantly increased in the ZYPs group(both P<0.05).After treatment with ZYPs,a significant regulation of serum sex hormones was observed,including progesterone and estradiol.Both hormones were up-regulated compared with the control group(P=0.014 and 0.008),respectively.No significant differences were observed with regard to pregnancy outcomes including implantation rates,biochemical pregnancy rates,clinical pregnancy rates,live birth rates,and pregnancy loss rates(all P>0.05).The administration of ZYPs did not increase the incidence of adverse events.The expressions of BMP15 and GDF9 in the ZYPs group were significantly up-regulated compared with the control group(both P<0.05).Conclusions:ZYPs exhibited beneficial effects in DOR patients undergoing IVF-ET,resulting in increments of oocytes and embryos,and up-regulation of BMP15 and GDF9 expressions in the FF.However,the effects of ZYPs on pregnancy outcomes should be assessed in clinical trials with larger sample sizes(Trial reqistration No.Chi CTR2100048441).

Effect of Patient Age and Embryo Parameters on Pregnancy Outcomein In Vitro Fertilization-Embryo Transfer(IVF-ET)

Objective To study the effect of patient age, the number and quality of embryos transferred on pregnancy outcome in in vitro fertilization-embryo transfer procedures （IVF-ETs）. Methods A retrospective study was conducted with infertile women who underwent a total of 1 800 cycles of lVF-ET and intracytoplasmic sperm injection （ICSI） at the Reproductive Medicine Center of the Third Affiliated Hospital of Guangzhou Medical College from Jan. 2006 to Dec. 2007. The patients were divided into three groups based on age （year）. 〈30, 30-34 and 235. The rates of clinical pregnancy and multiple pregnancies were compared in each group when 1-3 embryos and 0-3 goodquality embryos were transferred respectively. Results 1） In the group of patients aged 〈30 years, there was no significant difference in pregnancy outcomes with 1-3 embryos transferred. However, pregnancy rates were similar when 2 3 good-quality embryos were transferred, which was significantly higher compared with 0-1 good-quality embryos transferred; the incidence of multiple pregnancies was not an issue when only 1 embryo was transferred. 2） The pregnancy rate of the patients aged 30 34 was not significant not only when only 2-3 embryos were transferred but also when 2-3 good-quality embryos were transferred, which was significant compared with when 1 embryo or 0 1 good-quality embryo was transferred. The subgroup of 3 good-quality embryos transferred, at the same time, was expected to significantly increase multiple pregnancy rate. 3） For the patients aged 235, there were similar pregnancy rates in the subgroup involving 1-3 embryos transferred. Compared with 0-2 good-quality embryos transferred, the pregnancy rate was significantly higher in the patients with 3 good-quality embryos transferred. An increased trend toward multiple pregnancies was observed among not only the subgroups with 1-3 embryos transferred, but also when 1-3 good-quality embryos were transferred, although it was significantly higher in patients with 3 good-quality embryo transferred. Conclusion In an effort to achieve the ideal pregnancy rate without the risk of multiple pregnancies, it is desirable to employ a single good-quality embryo transfer for patients aged 〈30 years and 2 good-quality embryos for patients aged 330. As older women （aged 335 years）, this is important, need to abstain from poor-quality embryo transferred by increasing the number of embryos transferred in an effort to improve the rate of clinical pregnancy, if the patients have had enough 2 high-quality embryos.

Impact of Body Mass Index on In Vitro Fertilization–Embryo Transfer Outcomes in Xinjiang,China

Background:To investigate the effect of body mass index(BMI)on the outcomes of in vitro fertilization–embryo transfer(IVF-ET)treatment,and to provide evidence for future clinical studies of infertile women with different body mass indices.Methods:The relationship between pregnancy outcome and BMI in 717 infertile women who underwent IVF-ET was analyzed.Results:A total of 531 out of 717 patients were classified as having a standard body weight,and 20 patients were classified as obese.We found a significant difference in the basal follicle-stimulating hormone(FSH)level among the groups;the basal FSH level was lower in the obese group(6.80±2.20 IU/L)than in the standard weight group(7.56±2.25 IU/L).However,there were no significant differences in the age of females,the age of males,basal estradiol(E2)and luteinizing hormone(LH)levels,length of infertility,and history of dysmenorrhea.Although the pregnancy rate was highest(54.6%)in the standard weight group and lowest(45.0%)in the obese group,there was no significant difference among these groups by Chi-square test analysis.Furthermore,there were no significant differences in gonadotropin-releasing hormone agonist days,number of 2PN,and the LH level on the day of human chorionic gonadotropin treatment among the groups.Conclusions:Obese women can improve a successful pregnancy rate after undergoing IVF–ET treatment by controlling weight.

目的探讨研究拮抗剂方案联合生长激素(Growth Hormone,GH)注射对卵巢低反应(Ovarian Hypore⁃sponsiveness,POR)患者妊娠结局的影响。方法回顾性选取2020年3月-2023年7月徐州市妇幼保健院进行体外受精-胚胎移植(In Vitro Fertilization-embryo transfer,IVF-ET)治疗并采用拮抗剂方案的80例POR患者的临床资料,根据是否应用GH进行分组,联合GH注射治疗的纳入观察组,单一使用拮抗剂方案的纳入对照组,每组40例。比较两组患者妊娠情况,包括获卵数、第3天可移植胚胎率、囊胚形成率、临床妊娠率、种植率、MⅡ卵率、正常受精率、第3天优质胚胎率和优质囊胚率。结果治疗后,两组MⅡ卵率、正常受精率、第3天优质胚胎率、优质囊胚率比较,差异无统计学意义(P均>0.05)。观察组获卵数为(10.78±4.02)个,高于对照组的(7.36±2.15)个,差异有统计学意义(t=4.745,P<0.05)。观察组在第3天可移植胚胎率、囊胚形成率、临床妊娠率、种植率均高于对照组,差异有统计学意义(P均<0.05)。结论拮抗剂方案联合GH注射可改善POR患者妊娠结局,提高患者生育成功率。

抗着丝点抗体阳性患者体外受精结局分析

目的:通过观察抗着丝点抗体(ACA)阳性患者体外受精-胚胎移植和自然试孕结局,探讨此类患者的生育策略。方法:采用病例对照研究回顾性分析2016年6月至2023年6月在浙江省人民医院接受体外受精-胚胎移植治疗且有抗核抗体(ANA)谱检查结果的3955例患者的临床资料。根据ACA结果将所纳入患者分为ACA阳性组和ACA阴性组。采用倾向评分匹配方法对两组进行1∶3配对,分别比较两组体外受精的胚胎结局;并采用自身对照分析不同授精方法和是否应用免疫抑制剂对结局的影响;对ACA阳性患者体外受精失败后的自然试孕和疾病进展进行随访。结果:ACA阳性患者34例,占总病例数的0.86%,占ANA阳性体外受精患者数的2.51%。无论是接受常规体外受精(c-IVF)还是卵胞质内单精子注射(ICSI)的患者,ACA阳性组卵母细胞成熟度和受精情况均与ACA阴性组有明显差异(均P<0.01),且ACA阳性组授精后第三日(D3)次优胚数和D3优胚数均减少(均P<0.05)。5例ACA阳性患者自身ICSI周期相比c-IVF周期双原核(2PN)率未提高(P>0.05),D3优胚数和D3次优胚数减少(均P<0.05)。12例ACA阳性患者经过免疫抑制剂治疗1~2个月后再行c-IVF/ICSI,用药前后获卵和受精情况均未改变(均P>0.05),2PN胚胎卵裂率改善(P<0.05)。ACA阳性组与ACA阴性组移植胚胎数相近,但ACA阳性组胚胎着床率、临床妊娠率显著低于ACA阴性组(均P<0.05),流产率差异无统计学意义(P>0.05)。27例ACA阳性患者体外受精失败后尝试自然试孕或人工授精,共获临床妊娠7例。结论:血清ACA阳性会干扰卵母细胞的成熟和正常受精过程,使用ICSI和免疫抑制剂不能改善受精结局,但ACA阳性患者有可能获得自然妊娠。

精子DNA碎片对体外受精-胚胎移植妊娠结局及胚胎发育的影响

目的:分析精子DNA碎片指数(DFI)对体外受精-新鲜胚胎移植(IVF-ET)助孕及活产结局的影响。方法:选取2015年6月至2020年12月因女方因素首次行IVF并进行新鲜胚胎移植的患者共947例,根据DFI分为低、中、高3组:DFI<15%、15≤DFI≤30%和30%<DFI,比较3组双方基础数据,女方包括年龄、体质量指数(BMI)、基础生殖激素、AMH等;男方包括年龄、BMI、精液参数;超促排卵参数;处理前和处理后IVF精液参数;促排卵结局、胚胎质量及妊娠结局。结果:不同DFI水平间相比,双方年龄在3组间均有显著性差异,15≤DFI≤30%和30%<DFI组双方年龄显著大于DFI<15%组;基础状态精液参数中前向运动精子百分率、非前向运动精子百分率、不活动精子百分率,以及IVF处理前精子总活率、前向运动精子百分率在3组间也均有显著差异(P<0.01);中和高DFI组中基础精子正常形态率、IVF处理前精子浓度、精子总数和处理后精子浓度均显著低于低DFI组;30%<DFI组无论是精液处理前还是精液处理后精子总数均显著低于其他两组(P<0.01)。此外,中和高DFI组受精率显著低于低DFI组,其他临床数据包括促排卵参数、胚胎质量、妊娠结局组间均无显著差异。结论:高DFI水平对精子活率产生显著影响,IVF精液处理后DFI水平与精子浓度、精子总数、受精率均呈显著负相关,对胚胎质量及妊娠结局无影响。

血清白介素-2水平与卵巢储备功能减退患者体外受精-胚胎移植妊娠结局的关系

目的探讨血清白介素-2(IL-2)水平与卵巢储备功能减退(DOR)患者体外受精-胚胎移植(IVF-ET)妊娠结局的关系。方法选取2020年9月至2022年9月唐山市妇幼保健院收治的305例采用IVF-ET助孕的DOR患者作为观察组,选取本院同期305例正常健康孕妇作为对照组,观察组根据助孕结局分为妊娠组和未妊娠组。比较观察组和对照组血清IL-2水平,统计观察组妊娠结局,采用Logistic回归分析DOR患者IVF-ET治疗后妊娠失败的影响因素,绘制受试者工作特征(ROC)曲线分析各血清指标对DOR患者IVF-ET治疗后妊娠失败的预测价值。结果观察组血清IL-2水平高于对照组(P<0.05)。305例DOR患者妊娠成功率为53.11%(162/305)。未妊娠组移植前、后血清IL-2水平、窦卵泡计数<5发生率均高于妊娠组,血清抗米勒管激素(AMH)水平低于妊娠组(P<0.05)。窦卵泡计数少、血清AMH低表达、移植前血清IL-2高表达是DOR患者IVF-ET治疗后妊娠失败的影响因素(P<0.05)。血清AMH和移植前血清IL-2联合预测效能高于单独预测。结论血清IL-2水平与DOR患者IVF-ET妊娠结局密切相关,其或可成为临床预测DOR患者IVF-ET妊娠结局的辅助指标。
