Live births from in vitro fertilization-embryo transfer following the administration of gonadotropin-releasing hormone agonist without gonadotropins:Two case reports

BACKGROUND The prevalence of female infertility between the ages of 25 and 44 is 3.5%to 16.7%in developed countries and 6.9%to 9.3%in developing countries.This means that infertility affects one in six couples and is recognized by the World Health Organization as the fifth most serious global disability.The International Committee for Monitoring Assisted Reproductive Technology reported that the global total of babies born as a result of assisted reproductive technology procedures and other advanced fertility treatments is more than 8 million.Advancements in controlled ovarian hyperstimulation procedures led to crucial accomplishments in human fertility treatments.The European Society for Human Reproduction and Embryology guideline on ovarian stimulation gave us valuable evidence-based recommendations to optimize ovarian stimulation in assisted reproductive technology.Conventional ovarian stimulation protocols for in vitro fertilization(IVF)–embryo transfer are based upon the administration of gonadotropins combined with gonadotropin-releasing hormone(GnRH)analogues,either GnRH agonists(GnRHa)or antagonists.The development of ovarian cysts requires the combination of GnRHa and gonadotropins for controlled ovarian hyperstimulation.However,in rare cases patients may develop an ovarian hyper response after administration of GnRHa alone.CASE SUMMARY Here,two case studies were conducted.In the first case,a 33-year-old female diagnosed with polycystic ovary syndrome presented for her first IVF cycle at our reproductive center.Fourteen days after triptorelin acetate was administrated(day 18 of her menstrual cycle),bilateral ovaries presented polycystic manifestations.The patient was given 5000 IU of human chorionic gonadotropin.Twenty-two oocytes were obtained,and eight embryos formed.Two blastospheres were transferred in the frozen-thawed embryo transfer cycle,and the patient was impregnated.In the second case,a 37-year-old woman presented to the reproductive center for her first donor IVF cycle.Fourteen days after GnRHa administration,the transvaginal ultrasound revealed six follicles measuring 17-26 mm in the bilateral ovaries.The patient was given 10000 IU of human chorionic gonadotropin.Three oocytes were obtained,and three embryos formed.Two high-grade embryos were transferred in the frozen-thawed embryo transfer cycle,and the patient was impregnated.CONCLUSION These two special cases provide valuable knowledge through our experience.We hypothesize that oocyte retrieval can be an alternative to cycle cancellation in these conditions.Considering the high progesterone level in most cases of this situation,we advocate freezing embryos after oocyte retrieval rather than fresh embryo transfer.

Effect of Mitochondrial Function of Ovarian Granulosa Cells on In Vitro Fertilization and Embryo Transfer Outcomes in Obese Polycystic Ovary Syndrome Patients

Objective:To investigate the effect of abnormal ovarian granulosa cell metabolism on in vitro fertilization and embryo transfer(IVF-ET)outcomes in obese polycystic ovary syndrome(PCOS)patients.Methods:Patients with PCOS who met the study criteria were screened according to the inclusion criteria.A total of 32 patients with obese PCOS were recruited into the study group,and 39 patients with non-obese PCOS were recruited into the control group.The general data(age,body mass index,and years of infertility),insulin resistance index(HOMA-IR),follicle-stimulating hormone(FSH),luteinizing hormone(LH),granulosa cell mitochondrial function,and IVF-ET outcome of patients in the study group and control group were retrospectively analyzed.Results:The differences in age and years of infertility between the study group and the control group were insignificant(P>0.05),and the body mass index(BMI)of the study group and control group was 30.5±1.24 kg/m2 and 22.3±1.12 kg/m2,respectively,in which the difference was statistically significant(P<0.05);the HOMA-IR of the study group was significantly higher than that of the control group(P<0.05);the reactive oxygen species(ROS)in the study group was significantly higher than that in the control group(P<0.05),and the ATP content in the study group was significantly lower than that in the control group(P<0.05);comparing the FSH and LH levels between the two groups,the difference was not statistically significant(P>0.05);the rate of IVF-ET failure was significantly higher in the study group than in the control group.Conclusion:PCOS is a complex endocrine disorder,and obesity is one of the independent risk factors for the development of PCOS.

Post-salpingectomy interstitial heterotopic pregnancy after in vitro fertilization and embryo transfer:A case report

BACKGROUND Heterotopic pregnancy(HP)refers to the coexistence of ectopic pregnancy and intrauterine pregnancy.Salpingectomy is proposed as a pretreatment before in vitro fertilization and embryo transfer(IVF-ET)to reduce the risk of HP.HP after IVF-ET occurs in women who had already underwent bilateral salpingectomy,even though it is extremely rare.CASE SUMMARY A case of a 29-year-old woman with recurrent interstitial HP after IVF-ET following salpingectomy is presented.The main symptom was a sudden and worsening pelvic pain.Physical examinations revealed signs of peritoneal bleeding and irritation with stable vital signs.Transvaginal ultrasound showed a live intrauterine pregnancy and another live embryo with cardiac activity in the left cornu extending beyond the lateral edge of the uterus.Her hemoglobin concentration was 8.0 g/dL,and serum human chorionic gonadotropin value was 171116.9 mIU/mL.With the diagnosis of ruptured HP with internal bleeding,an emergency laparoscopic resection of left cornu was performed.The interstitial pregnancy was removed with caution to protect the intrauterine pregnancy.After the surgical treatment,the intrauterine pregnancy continued with no complications.A healthy baby was delivered by caesarean section at 39 wk.Outcomes of another three cases are further summarized.CONCLUSION Post-salpingectomy HP is a rare but challenging condition.Surgical treatment is preferred in the case with a viable intrauterine pregnancy.

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.

The Effect of Insulin Resistance on In-Vitro Fertilization-Embryo Transfer in Women without Polycystic Ovary Syndrome

Purpose: Insulin resistance (IR) plays an important role in the pathogenesis of polycystic ovary syndrome (PCOS);therefore, insulin-sensitizing agents are widely used to improve IR in women with PCOS. However, whether IR in patients without PCOS should be treated remains uncertain. This study aims to clarify whether IR in patients without PCOS affects the outcomes of in-vitro fertilization-embryo transfer (IVF-ET) and pregnancy. Methods: Between January 2011 and December 2013, we retrospectively reviewed the medical records of 116 non-PCOS patients who underwent the first IVF–ET cycle. IR was calculated using the homeostasis model assessment (HOMA) index [HOMA-IR = (insulin × glucose)/405]. A HOMA index of >2.5 was used to indicate IR. Based on the HOMA index calculation, 28 patients were IR(+) and 88 patients had normal insulin sensitivity. We retrospectively compared the response with controlled ovarian hyperstimulation, retrieved oocytes number, fertilization rates, pregnancy rate, live birth rates, and gestational diabetes mellitus (GDM) incidence. Results: There were no significant differences in human menopausal gonadotropin administration, peak estradiol, retrieved oocyte number, fertilized embryo number, good quality embryo number, implantation rate, clinical pregnancy rate, miscarriage rate, delivery rate, or ovarian hyperstimulation syndrome and GDM incidences between the groups. Conclusion: IR in non-PCOS patients has no effect on IVF-ET outcomes or perinatal prognosis.

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.

Intramural pregnancy after in vitro fertilization and embryo transfer:A case report

BACKGROUND Intramural pregnancy is a rare type of ectopic pregnancy,which is diagnosed by transvaginal ultrasound and magnetic resonance imaging.Management strategies vary depending on the site of the pregnancy,the gestational age and the desire to maintain fertility.The incidence of intramural pregnancy in assisted reproductive technology is higher than that in natural pregnancy.CASE SUMMARY We present a case of intramural pregnancy after in vitro fertilization and elective single embryo transfer following salpingectomy.The patient was completely asymptomatic and her serumβ-human chorionic gonadotropin level increased from 290 m IU/m L to 1759 m IU/m L.Three-dimensional transvaginal ultrasound indicated a heterogeneous echogenic mass arising from the uterine fundus which was surrounded by myometrium and a slender and extremely hypoechoic area stretching to the uterine cavity which was thought to be a fistulous tract.Therefore,we considered a diagnosis of intramural pregnancy and laparoscopic surgery was conducted at 7 wk gestation.CONCLUSION Early diagnosis and treatment of intramural pregnancy is significant for maintaining fertility.

Double Pulmonary Embolism and Left Common Iliac Vein Thrombosis after in vitro fertilization and embryo transfer： a Case Report

This article discusses the mechanism, diagnosis, and treatment of a case of double pulmonary embolism and left common iliac vein thrombosis following in vitro fertilization （IVF） and embryo transfer （ET） to arouse vigilance for unexpected thrombosis after ovarian hyperstimulation and to serve as a clinical reference of this condition. This paper reports the case of a woman with double pulmonary embolism and left common iliac vein thrombosis after IVF-ET and the successful management of this condition. The woman had primary infertility, and underwent IVF-ET with 14 ooeytes recovered and two embryos transferred. The patient suffered breathing difficulty 17 days after the ET, and was hospitalized 6 days later as her condition had exacerbated. Computed tomographic （CT） angiography of pulmonary arteries showed double pulmonary embolism, left common iliae vein thrombosis, abnormal density shadow in uterine appendages, and ascites. A healthy baby boy and girl were safely delivered by Caesarean section after successful treatment. Thrombosis after IVF-ET is an uncommon but life-threatening complication and concurrent pulmonary embolism is even rarer. It is suggested that careful thrombosis risk assessment be taken before therapy and particular attention be paid to patients with special body constitutions to develop thrombosis. Whenever patients experience breathing difficulty after IVF-ET, it is strongly advised to examine the possibility of pulmonary embolism. The main treatments for thrombosis are anticoagulant therapy by low-molecular-weight heparin and thrombolysis by urokinase.

Laparoscopic management of an ectopic pregnancy after in vitro fertilization and embryo transfer at CHRACERH:A case report

1.Introduction Initially,in vitro fertilization and embryo transfer(IVF-ET)was designed to solve tubal factors infertility(TFI)by placing the embryo(s)within the uterine cavity.However,in some cases,an ectopic implantation occurs as the embryo can enter the tube.Ectopic pregnancy(EP)is the location of the pregnancy outside the intrauterine cavity.The prevalence of EP following assisted reproductive technology(ART)ranges between 2.1%and 8.6%of all pregnancies and it can reach up to 11%inwomen with tubal factors infertility history.

Reproductive Outcomes in Women with Prior Cesarean Section Undergoing In Vitro Fertilization:A Retrospective Case-control Study

The impact of prior cesarean section（CS） on the pregnancy and neonatal outcomes of in vitro fertilization and embryo transfer（IVF-ET） was investigated. A retrospective analysis was performed on 144 patients with prior CS between January 2013 and December 2015. The pregnancy, delivery, and neonatal outcomes of patients who had previous CS delivery and received IVF-ET were analyzed. The control group comprised 166 patients who had only previous vaginal delivery（VD） and received IVF-ET during the same period. The results showed that the basal follicle stimulating hormone level, estradiol level on human chorionic gonadotropin（h CG） day, gonadotrophin dosage, duration of stimulation, retrieved oocytes, fertilization rate, high-quality embryo rate, multiple birth rate, abortion rate and ectopic pregnancy rate had no significant difference between the two groups（P〉0.05）. The pregnancy rate（40.28% vs. 54.22%） and implantation rate（24.01% vs. 34.67%） were significantly lower（P〈0.05）, and the ratio of embryo difficulty transfer（9/144 vs. 0/166） was significantly higher in CS group than in VD group. The risk of pernicious placenta previa and postpartum hemorrhage in twin deliveries was significantly increased in CS group as compared with that in VD group（P〈0.05）, and gestational age and neonatal birth weight were significantly reduced in twin deliveries as compared with singleton deliveries in both groups（P〈0.05）. It was suggested that the existence of CS scar may impact embryo implantation and clinical pregnancy outcome, and increase the difficulty of ET. We should limit the number of transfer embryos to avoid multiple pregnancies and strengthen gestational supervision in patients with cesarean scar.

基于“冲为血海”的分期针灸对肾虚痰湿型多囊卵巢综合征患者IVF-ET助孕结局及性激素、子宫内膜血流参数的影响

目的评价基于“冲为血海”的分期针灸对肾虚痰湿型多囊卵巢综合征患者体外受精-胚胎移植(IVF-ET)助孕结局及性激素、子宫内膜血流参数的影响。方法选取2020年1月至2022年1月于河南中医药大学第一附属医院生殖医学科接受治疗的60例肾虚痰湿型多囊卵巢综合征,分为对照组(30例)与联合组(30例)。对照组接受单纯卵泡期长方案促排卵,在阴道B超引导下经阴道穿刺取卵,取卵后72 h移植优质胚胎;联合组在对照组基础上接受基于“冲为血海”的分期针灸,直至取卵,IVF-ET后随访10个月观察妊娠结局。比较两组胚胎获得及种植情况、IVF-ET助孕结局,治疗前和治疗后子宫内膜血流参数、厚度、类型,性激素、中医证候积分,治疗期间不良反应。结果联合组获卵数、优质胚胎率、胚胎种植率、临床妊娠率、生化妊娠率、活产率更高(P<0.05)。与治疗前比较,治疗后两组血流搏动指数(PI)、血流阻力指数(RI),血清睾酮(T)水平降低,且联合组更低(P<0.05)。与治疗前比较,治疗后两组子宫内膜厚度、子宫内膜分型A型比例,血清孕酮(P)、雌二醇(E_(2))水平升高,且联合组更高(P<0.05)。两组不良反应发生率差异无统计学意义(P>0.05)。结论基于“冲为血海”的分期针灸治疗肾虚痰湿型多囊卵巢综合征可缓解中医症候,调节性激素、子宫内膜血流参数,改善子宫内膜形态,促进IVF-ET中胚胎的获得及种植,最终优化IVF-ET助孕结局。

卵巢储备功能低下患者血清AMH、Betatrophin水平与卵巢反应性、IVF-ET妊娠结局关系

目的:探讨卵巢储备功能低下(DOR)患者血清抗苗勒管激素(AMH)、促代谢因子(Betatrophin)水平与卵巢反应性及体外受精-胚胎移植(IVF-ET)妊娠结局的关系。方法:收集2019年12月-2022年12月在本院行IVF-ET的DOR患者137例临床资料,根据卵巢反应性将患者分为低反应组(n=112)、正常反应组(n=16)、高反应组(n=9);根据妊娠结局将患者分为妊娠成功组(n=44)和妊娠失败组(n=93)。酶联免疫吸附法检测血清AMH、Betatrophin水平,受试者工作特性(ROC)曲线评估2项指标预测IVF-ET妊娠结局价值;多因素logistic回归分析影响妊娠的因素。结果:低反应组、正常组、高反应组血清AMH水平(0.49±0.13 ng/ml、0.98±0.21 ng/ml、1.05±0.26 ng/ml)依次升高,血清Betatrophin水平(156.95±16.33 pg/ml、112.17±13.42 pg/ml、92.64±11.03 pg/ml)依次降低;妊娠成功组血清AMH水平(1.07±0.36 ng/ml)高于妊娠失败组(0.34±0.19 ng/ml),Betatrophin水平(136.29±14.42 pg/ml)低于妊娠失败组(216.16±21.05 pg/ml)(均P<0.05)。血清AMH、Betatrophin预测DOR患者IVF-ET妊娠结局的曲线下面积(AUC)(95%CI)别为0.857、0.771,两项指标联合预测的AUC为0.904。多因素logistic回归分析显示,卵泡刺激素/促黄体生成素比值≥2、卵巢低反应、AMH≤0.71 ng/ml、Betatrophin≥176.23 pg/ml是DOR患者IVF-ET妊娠失败的独立危险因素(P<0.05)。结论:血清AMH、Betatrophin水平与DOR患者卵巢反应性、IVF-ET妊娠结局有关,二者有望作为预测DOR患者IVF-ET妊娠结局的生物标记物。

不孕症患者IVF-ET后不明原因反复种植失败的预测因素分析

目的分析不孕症患者体外受精-胚胎移植(IVF-ET)后不明原因反复种植失败(RIF)的预测因素。方法前瞻性纳入2020年6月至2022年6月无锡市妇幼保健院接诊的82例IVF-ET的不孕症患者作为研究对象,根据RIF发生原因将患者分为RIF组与不明原因RIF组。比较两组患者的基线资料、实验室指标,分析IVF-ET后不明原因RIF的影响因素;分析各项影响因素对不孕症患者IVF-ET后不明原因RIF的预测价值。结果82例患者中不明原因RIF 22例,占比为26.83%。Logistic回归分析结果显示,高水平CD4^(+)/CD8^(+)、纤维蛋白原(FIB)是不孕症患者IVF-ET后不明原因RIF的独立危险因素(OR>1,P<0.05),高水平抗米勒管激素(AMH)、血管内皮生长因子(VEGF)、粒细胞集落刺激因子(G-CSF)是其保护因素(OR<1,P<0.05)。绘制受试者工作特征(ROC)曲线结果显示,AMH、CD4^(+)/CD8^(+)、FIB、VEGF、G-CSF预测不孕症患者IVF-ET后不明原因RIF的曲线下面积(AUC)>0.70,均具有一定预测价值。结论AMH、CD4^(+)/CD8^(+)、FIB、VEGF、G-CSF对不孕症患者IVF-ET后不明原因RIF有一定预测价值。
