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.

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.

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.

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.

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.

Effect of electroacupuncture on oocyte quality and pregnancy of patients with PCOS undergoing in vitro fertilization and embryo transfer

Objective To observe the impacts of electroacupuncture （EA） on oocyte quality and pregnant outcome for the patients with polycystic ovary syndrome （PCOS） undergoing in vitro fertilization and embryo transfer （IVF-ET） and explore its potential mechanism. Methods Sixty-six patients with PCOS and undergoing IVF-ET were divided into two groups randomly, including an observation group （34 cases） and a control group （32 cases）. Ethinylestradiol and cyproterone acetate tablets and gonadotropin-releasing hormone agonist were administered for long-program superovulation in either group. In the observation group, the intervention of EA was applied to Guānyuán （关元 CV 4）, Zhōngjí （中极 CV 3）, Sānyīnjiāo （三阴交 SP 6）, Zǐgōng （子宫 EX-CA 1） and Tàixī （太溪 KI 3） additionally for 30 min, once daily, 1 menstrual cycle before controlled ovarian hyperstimulation （COH） and during COH. The pregnant outcome, evaluation of kidney deficiency syndrome, blood hormone level on the day of human chorionic gonadotropin injection and the concentrations of stem cell factor （SCF） in the serum and follicular fluid on the day of oocyte collection were compared between the two groups. Results The score of kidney deficiency symptoms was reduced remarkably after treatment in either group and the improvement in the observation group was superior to that in the control group （P0.01）. The fertilization rate [（76.25？±？20.33）% vs （66.34？±？15.44）%], cleavage rate [（98.66？±？3.70）% vs （94.47？±？9.45）%] and the rate of high-quality embryos [（60.20？±？22.20）% vs （50.55？±？16.15）%] in the observation group were all superior to those in the control group separately （all P0.05）. Clinical pregnancy rate （46.67%, 14/30） in the observation group was higher than that （37.93%, 11/29） in the control group, but without statistical difference （P0.05）. SCF concentrations in the serum and follicular fluid on the day of oocyte collection in the observation group were higher obviously than those in the control group （both P0.05）. Conclusion Electroacupuncture plays an active role in the pregnant outcomes of PCOS patients undergoing IVF-ET and it can relieve the symptoms of kidney deficiency in terms of TCM and improve clinical pregnant rate. The mechanism is relevant to the overall adjustment of organic endocrinal system and the local micro-environment of ovary and the improvement of oocyte quality through the up-regulation of SCF concentration.

Embryo Glue在IVF-ET临床应用的前瞻性研究

目的：研究EmbrycGlue是否有利于IVF-ET妊娠率的提高。方法：将2003年2月～2004年2月在本中心接受常规体外受精-胚胎移植（IVF-ET）或单精子卵母细胞浆内注射（ICSI）治疗周期的180例不孕患者随机分成两组进行双盲试验，实验组共100例，使用EmbryoGlue作为胚胎移植液，对照组80例，使用IVF-20胚胎培养液作为移植液。结果：实验组平均移植胚胎数为2．5个，对照组为2．4个（P〉0．05），实验组临床妊娠率及胚胎种植率分别为46．0％、32．7％，对照组为38．7％、26．4％，实验组临床妊娠率及胚胎种植率与对照组相比有上升趋势。结论：使用Embryo Glue作为胚胎移植液有助于提高妊娠率。

Clinical Effects of the Follicular Phase Long Regimen and Luteal Phase Long Regimen on Ovulation Induction in IVF-ET Treatment: A Meta-Analysis

Objective:To systematically evaluate the clinical effects of the follicular phase long regimen and the luteal phase long regimen on ovulation induction in IVF-ET treatment.Methods:Databases including PubMed,Embase,Cochrane Library,CNKI,Chinese Biomedical Literature(CBM),VIP,Wanfang,and others were searched up to January 2021.Clinical studies on ovulation induction using the follicular phase long regimen and luteal phase long regimen in IVF-ET treatment were identified.Literature screening,data extraction,and quality evaluation were conducted based on inclusion and exclusion criteria.Meta-analysis was performed using RevMan 5.3 software.Results:After screening,a total of 11 studies were included,comprising 21,544 patients:9,974 in the follicular phase long regimen group and 11,570 in the luteal phase long regimen group.The meta-analysis results were as follows:(1)The number of Gn days and the total amount of Gn in the follicular phase long regimen were higher than those in the luteal phase long regimen(P<0.05);(2)The number of eggs obtained in the follicular phase long regimen was higher than that in the luteal phase long regimen(P<0.05).There were no significant differences in the rate of embryo optimization and cycle cancellation between the two groups(P>0.05);(3)The embryo implantation rate and clinical pregnancy rate in the follicular phase long regimen were higher than those in the luteal phase long regimen(P<0.05),while the abortion rate in the follicular phase long regimen was lower than that in the luteal phase long regimen(P<0.05).Conclusion:Compared to the luteal phase long regimen,the follicular phase long regimen involves more Gn days and a higher total amount of Gn.The optimal embryo rate and cycle cancellation rate were similar between the regimens,but the follicular phase long regimen resulted in more eggs,significantly improved the implantation and clinical pregnancy rates,and reduced the abortion rate.However,these conclusions require further validation through more multicenter,large-sample RCT studies.

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.

Normal epigenetic inheritance in mice conceived by in vitro fertilization and embryo transfer

An association between assisted reproductive technology （ART） and neurobehavioral imprinting disorders has been reported in many studies, and it seems that ART may interfere with imprint reprogramming. However, it has never been explored whether epigenetic erros or imprinting disease susceptibility induced by ART can be inherited transgenerationally. Hence, the aim of this study was to determine the effect of in vitro fertilization and embryo transfer （IVF-ET） on transgenerational inheritance in am inbred mouse model. Mice derived from IVF-ET were outcrossed to wild-type C57BL/6J to obtain their female and male line F2 and F3 generations. Their behavior, morphology, histology, and DNA methylation status at several important differentially methylated regions （DMRs） were analyzed by Morris water maze, hematoxylin and eosin （H＆E） staining, and bisulfite genomic sequencing. No significant differences in spatial learning or phenotypic abnormality were found in adults derived from IVF （F1） and female and male line F2 and F3 generations. A borderline trend of hypomethylation was found in H19 DMR CpG island 3 in the female line-derived F3 generation （0.40±0.118, P=0.086）. Methylation status in H19/Igf2 DMR island 1, Igf2 DMR, KvDMR, and Snrpn DMR displayed normal patterns. Methylation percentage did not differ significantly from that of adults conceived naturally, and the expression of the genes they regulated was not disturbed. Transgenerational integrity, such as behavior, morphology, histology, and DNA methylation status, was maintained in these generations, which indicates that exposure of female germ cells to hormonel stimulation and gamete manipulation might not affect the individuals and their descendents.

Impact of Blood Clot in Oocyte-Corona-Cumulus Complex during in vitro Fertilization and Embryo Transfer

Objective To study the impact of blood clots in the oocyte-corona-cumulus complexes （OCCC） during in vitro fertilization and embryo transfer （IVF-ET）.Methods The OCCCs were harvested from the patients undergoing long protocol ovarian hyperstimulation. The OCCCs with blood clots removed or not, were randomly grouped into A or B. The OCCCs without blood clots were group C （the control）.Results The patient＇s age, infertility duration, the average GN consumption, the average days of superovulation and an average number of harvested oocytes showed no significant difference in the 3 groups. The fertilization rate and 2PN rate in group A were the highest, which were 85.4% and 71.1%, respectively, followed by group C, which were 77.5% and 64.9%, respectively. The lowest fertilization rate and 2PN rate were in group B, 75.8% and 62.2%, respectively. Those in group A were significantly higher than those in groups B and C （P〈0.01）, while there was no significant difference between group B and group C. The implantation rates and pregnancy rates showed no significant difference in the 3 groups after transplantation, even if group A got the highest rate among the 3 groups. Conclusion Removing the blood clots in OCCC can improve the outcome of IVF-ET without increasing the cost and complexity of the operation.

Is there A Link between Serum Thyroid Stimulating Hormone Level and the Results of in vitro Fertilization and Embryo Transfer?

Objective To analyze the clinical features and outcomes in infertile patients with different levels of thyroid stimulating hormone （TSH） undergoing IVF/ICSL and to investigate whether inappropriate level of TSH has the adverse effect on the results of the IVF-ET.Methods A total of 389 patients undergoing IVF/ICSI from January 2009 to December 2011 were divided into 3 groups according to the basal TSH level： group A （TSH〈 2.0 mlU/L）, group B （TSH 2.0-4.5 mlU/L） and group C （TSH〉4.5 mlU/L）. Oocyte retrieved, fertilization rate, cleavage rate, available embryo rate, pregnancy rate and miscarriage rate were analyzed to explore whether serum TSH level was correlated with the results of lVF/ICSI.Results There were no differences in number of oocyte retrieved, fertilization rate, cleavage rate and available embryo rate among 3 groups （P〉0.05）. Clinical pregnancy rate in group B （43.0%） was significantly higher than that in group A （30.2%） and group B （23.5%）, respectively （P〈0.05）. There were no significant differences in miscarriage rate among 3 groups.Conclusion TSH level has no effect on fertility rate or miscarriage rate in patients undergoing IVF/ICSL Inadequacy TSH level would decrease the IVF/ICSI pregnancy rate.

Relationship between Pronuclear Scoring and Embryo Quality and Implantation Potential in IVF-ET

To assess the relationship between pronuclear scoring and day-3 embryo quality and pregnancy outcome and to determine the Clinical value of pronuclear stage scoring system in human in vitro fertilization-embryo transfer （IVF-ET） program, a pronuclear scoring system was used to score zygotes 16-20 h after insemination during conventional IVF or intracytoplasmic sperm injection （ICSI）. The embryos were classified into groups Z1, Z2, Z3 and Z4, Comparisons were made of the rates of arrested embryos and excellent embryos on day 3. Comparisons of pregnancy outcome were made only in those patients in whom cohorts of similarly Z-scored embryos were transferred, The results showed that there were less arrested embryos and more excellent embryos on day 3 in groups Z1 and Z2 than those in group Z3 and Z4, More embryos arrested and less excellent embryos developed in group Z4 than group Z3. The clinical pregnancy rates resulting from the transfer of single pronuclear score homologous embryo types were similar among groups Z1, Z2 and Z3. Implantation rates of group Z1 were higher （P〈0.05） than that of group Z3, These findings suggests that pronuclear scoring can predict developmental ability on day 3 and implantation potential. A evaluation that combines the Z-score and day 3 embryo morphology is useful in the determination of the most viable embryos and the number of embryos for transfer.
