Analysis of Factors Influencing Pregnancy Rate in Frozenthawed Embryo Transfer

Objective To analyse factors influencing the outcome of frozen-thawed embryo transfer （FET）. Method A retrospective analysis was performed in our center on 129 thawing cycles from March 2001 to April 2003. The related parameters were compared between conceived and non-conceived cycles. Results There were totally 129 clinical pregnancies in these transfers （pregnancy rate： 27.1%）. Frozen-thawed embryos were transferred to natural cycles and CC cycling and hormone replacement treatment had equal success. Groups of IVF and ICSI did not differ significantly in pregnancy rates （P〉0.05）. The pregnancy rates for one, two, three and four pre-embryos transfer were 0, 20.0%,44.1% and 75.0%, respectively （P〈0.05）. There were statistical differences between pregnancy group or non- pregnancy group in the endometrial thickness, CES, CES/No. of embryo. A higher pregnancy rate was observed in embryo transfers which had at least one 4-cell grade I embryo （d 2）（P〈0.01）. Conclusions The most important factors influencing the implantation rate and pregnancy rate of frozen-thawed embryo transfer are age, endometrium thickness, and the number, morphology and growth rate of transferred frozen embryos of women participants.

The Effect of Luteal-Phase Support with Triptrolin Administration on Implantation and Clinical Pregnancy Rate in Assisted Reproductive Technology

Background: Luteal phase support with GnRH agonist administration has been shown to be effective in improving the outcome of assisted reproductive technology. The goal of this study was to evaluate the effect of single dose Triptrolin (a GnRH agonist) on the probability of the clinical pregnancy rate following embryo transfer (ET) in assisted reproductive techniques (ART). Methods: In this double blinded randomized clinical trial, 340 infertile women who were candidates for intra-cytoplasmic sperm injection (ICSI) were randomly assigned to receive GnRH agonist (Triptrolin) in the luteal phase or placebo. In the intervention group, 0.1 mg Triptrolin was injected subcutaneously, while the control group received normal saline. The clinical pregnancy and implantation rate were compared between the two groups using chi-2 and t-test. P-values less than 0.05 were considered significant. The registration number of this clinical trial is IRCT 2014030916912N1. Results: Administration of 0.1 mg Triptrolin on day 6 after oocyte pick up showed no superiority over placebo in implantation (16.9% - 14%, P = 0.40) and clinical pregnancy rates (32% - 29%, P = 0.66), but the rate of clinical pregnancy was higher in women who were below 27 years of age and those with PCO. Conclusion: Administration of Triptrolin was not superior to placebo for luteal phase support.

Effect of autologous bone marrow stem cells-scaffold transplantation on the ongoing pregnancy rate in intrauterine adhesion women:a randomized,controlled trial

Intrauterine adhesion is a major cause of female reproductive disorders.Although we and others uncontrolled pilot studies showed that treatment with autologous bone marrow stem cells made a few patients with severe intrauterine adhesion obtain live birth,no large sample randomized controlled studies on this therapeutic strategy in such patients have been reported so far.To verify if the therapy of autologous bone marrow stem cells-scaffold is superior to traditional treatment in moderate to severe intrauterine adhesion patients in increasing their ongoing pregnancy rate,we conducted this randomized controlled clinical trial.Totally 195 participants with moderate to severe intrauterine adhesion were screened and 152 of them were randomly assigned in a 1:1 ratio to either group with autologous bone marrow stem cells-scaffold plus Foley balloon catheter or group with only Foley balloon catheter(control group)from February 2016 to January 2020.The per-protocol analysis included 140 participants:72 in bone marrow stem cells-scaffold group and 68 in control group.The ongoing pregnancy occurred in 45/72(62.5%)participants in the bone marrow stem cells-scaffold group which was significantly higher than that in the control group(28/68,41.2%)(RR=1.52,95%CI 1.08–2.12,P=0.012).The situation was similar in live birth rate(bone marrow stem cells-scaffold group 56.9%(41/72)vs.control group 38.2%(26/68),RR=1.49,95%CI 1.04–2.14,P=0.027).Compared with control group,participants in bone marrow stem cells-scaffold group showed more menstrual blood volume in the 3rd and 6th cycles and maximal endometrial thickness in the 6th cycle after hysteroscopic adhesiolysis.The incidence of mild placenta accrete was increased in bone marrow stem cells-scaffold group and no severe adverse effects were observed.In conclusion,transplantation of bone marrow stem cells-scaffold into uterine cavities of the participants with moderate to severe intrauterine adhesion increased their ongoing pregnancy and live birth rates,and this therapy was relatively safe.

Pregnancy Rate after Embryo Transfer on Day 5 and Day 6 in IVF. A Systematic Review and Meta-Analysis

Study Question: The question: is there any difference in pregnancy rate between embryo transfer day 5 and day 6 in IVF? What Is Known Already? Blastocyst transfer is increasingly popular in assisted reproductive technology (ART) centers today. Very few articles concentrate on comparing Day 5 and Day 6 embryo transfer with conflict results. Objective, Study Design: Systematic review and meta-analysis of published controlled studies. Searches conducted from 2001-2020 on PubMed. Medline, EMBASE, and ISI Web of Science Electronic database is used to collect data, using the following search terms: blastocyst, Day 5, Day 6, embryo transfer (E.T.) and pregnancy rate. Materials, Setting, Methods: A total of 6 full-text articles preselected from 211 references, based on title and abstract. Two independent reviewers performed data selection and extraction according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement (PRISMA). This systematic review was conducted according to (PICO) standard. Random-effect meta-analysis performed on all data (overall analysis). Results and the Role of Chance: Data from 6 relevant articles were extracted and integrated into the meta-analysis that reported clinical pregnancy rate (CPR) as an outcome in 5640 cycles, 2274 cycle had embryo transfer at day 6 and the control was 3366 cycle had embryo transfer day 5 showed a significantly higher clinical pregnancy rate following Day 5 embryo transfer compared with Day 6 embryo transfer with odd ratio and 95% confidence limit 0.73 (0.66 - 0.82) p value < 0.000. Sensitivity analysis led to similar results and conclusions. Limitations, Reasons for Caution: The validity of meta-analysis results depends mainly on the quality and the number of published studies available. Indeed, this meta-analysis included no randomized controlled trial (RCT). Wider Implications of the Findings: In regards to the results of this original meta-analysis, ART practitioners should preferably transfer D5 rather than D6 blastocysts. Further RCTs are needed to address the question of whether D6 embryos should be transported.

Pregnancy Outcomes for Day 5 Versus Day 6 Single Frozen-thawed Blastocyst Transfer with Different Qualities of Embryos: A Large Matched-cohort Study

Objective This study aimed to determine whether the day of blastocyst expansion affects pregnancy outcomes in frozen-thawed blastocyst transfer(FBT)cycles.Methods A retrospective match-cohort study was conducted.Patients who underwent blastocyst transfer in frozen-thawed cycles at day 5 or 6 were matched for potential confounding factors.A total of 2207 matched pairs of FBT cycles were included from January 2016 to December 2019 in our Reproductive Medicine Center.Results The clinical pregnancy rate(CPR)and live birth rate(LBR)were significantly increased in day 5 blastocyst transfers when compared to day 6 blastocyst transfers,in terms of the same embryo quality.For FBT cycles with good-quality embryo,the CPR at day 5 and 6 was 61.30%and 57.56%,respectively(P=0.045),and the LBR was 44.79%and 36.16%,respectively(P<0.001).For FBT cycles with poor-quality embryo,the CPR at day 5 and 6 was 48.61%and 40.89%,respectively(P=0.006),and the LBR was 31.71%and 25.74%,respectively(P=0.019).The CPR for FBT cycles with good-quality embryo was statistically higher at day 6 than that at day 5 with poor-quality embryo transferred(57.56%vs.48.61%,P=0.001).Maternal age,anti-Müllerian hormone(AMH),endometrial thickness,embryo quality,and the day of blastocyst expansion were independently correlated with the CPR and LBR.The FBT cycles at day 5 had significantly higher CPR(adjusted odds ratio[OR]=1.246,95%confidence intervals[CI]:1.097–1.415,P=0.001)and LBR(adjusted OR=1.435,95%CI:1.258–1.637,P<0.001)than those at day 6.Conclusion The embryo quality is the primary indicator for FBT cycles.Day 5 blastocysts should be preferred when the quality of embryo at day 5 is the same as that at day 6.

A comparison of implantation, miscarriage and pregnancy rates of single and double day 3 embryo transfer between fresh and frozen thawed transfer cycles： a retrospective study

Background Reduced endometrial receptivity in hyperstimulated cycles may lead to a lower implantation rate and a lower clinical pregnancy rate,but it is unclear if it is also associated with an increase in pregnancy loss rate.The aim of this study was to compare the implantation,miscarriage,and pregnancy rates between fresh and frozen thawed transfer of one or two day-3 embryos,with a view to understanding whether or not reduced endometrial receptivity encountered in hyperstimulated cycles is associated with an increase in miscarriage rate.Methods This study involved a consecutive series of 1 551 single day-3 embryo transfer cycles and consecutive 5 919 double day-3 embryo transfer cycles in the Assisted Reproductive Unit of the Sir Run Run Shaw Hospital,Hangzhou,China,between January 2010 and December 2012.Results The implantation and clinical pregnancy rates （single embryo 30.7％ and double embryos 33.4％ and 51.4％）using fresh cycle were both significantly lower than that of frozen-thawed cycles （single embryo 35.8％ and double embryos 38.1％ and 57.8％）.There was no difference in biochemical loss or clinical miscarriage rates between the two groups.Conclusions Impairment of endometrial receptivity associated with ovarian hyperstimulation leads to implantation failure at a very early stage,resulting in an increased number of non-pregnancy.It does not lead to increase in biochemical or clinical losses.The significantly reduced ongoing pregnancy rates in both fresh single and double embryo transfer are therefore due to failure to achieve a pregnancy,rather than pregnancy loss after conception.

Acceleration of coasting enhances pregnancy rate in ICSI cycles at risk for ovarian hyperstimulation syndrome

Objective To assess the efficacy of adding Gn-releasing hormone antagonist（GnR HA） on the day of hC G triggering in a long luteal protocol without withholding the agonist in women who are at a risk to develop ovarian hyperstimulation syndrome（OHSS）.Methods This was a retrospective cohort study conducted upon 50 women who have elevated serum estradiol（E2） level 〉4 500 ng/L at the day of ovum triggering with hC G on a long agonist luteal protocol of controlled ovarian stimulation（COS）. When an exaggerated ovarian response was observed around day 10 of stimulation, immediately the next morning at 6 a.m. gonadotropin administration was stopped or reduced, and a single dose of ganirelix acetate（antagonist） was given sc continuation of the agonist dose hC G. Another serum E2 measurement was done at 6 p.m.（after 12 h of antagonist） then hC G, sc 250 mg and choriogonadotropin α were administered 14 h later after antagonist and documented the reduction of E2 level. Oocyte retrieval was conducted after 34-36 h of hC G administration. The measured outcomes were the level of E2 on the day of hC G injection, number of oocytes and their quality, pregnancy rate and the occurrence of OHSS and its grade in case it happened.Results The total dose for recombinant FSH was 25.3±6.4 ampoules（75 IU/ampoule） while it was 11.0±3.0 ampoules for the urinary hM G. A higher oocyte maturation rate（82.8%） and a high fertilization rate（87.8%） were observed. The mean endometrial thickness was 10.1±1.0 mm on the day of hC G triggering. The higher fertilization rate with the good endometrial thickness observed resulting in a higher pregnancy rate（78.0%, 39/50） with statistically significant（P〈0.05）. A significant reduction of E2 level was documented by a percentage around 40% before hC Ginjection. There were no reported cases of severe or moderate OHSS, however 13 cases（26%） were reported to have mild OHSS constituting.Conclusion Acceleration of coasting in cases of OHSS through treatment with GnR HA after pituitary suppression with GnR H agonist（GnR H-a） offered a novel approach to decrease E2 level, avoided cycle cancellation, and maintain excellent oocyte maturation rate, and finally result in high pregnancy rate with prevention of OHSS.

Clinical use of estimating glomerular filtration rate equ-ations during pregnancy

Background: Kidney disease, even when mild, was once considered so major an impediment to successful pregnancy and so dangerous to the mother’s wellbeing. High-risk pregnancy mainly associated to renal impairment may occur in 10-20% of gestations and it is very important that renal function is closely monitored to prevent or minimize maternal and fetal complications. This study was designed to investigate the performance of Cockcroft-Gault CGeq and the simplified MDRDeq equations in healthy pregnant women to assess renal function. Methods: We studied 167 normal ambulatory pregnant women and kidney function was contemporaneously estimated through the CGeq and the simplified MDRDeq and calculated through the creatinine clearance (Ccr). Serum and urinary creatinine were assayed using Jaffé reaction method in the same AutoAnalyser. Results: When we compared calculated and estimated clearences for measurement of kidney function we observed that CGeq overestimated renal function (CGeq = 168.41 ± 38.80 ml/ min/1.73 m2, Ccr = 146.27 ± 30.49 ml/min / 1.73 m2, p < 0.001), MDRDeq underestimated renal function (Ccr = 146.27 ± 30.49 ml/min / 1.73 m2, MDRDeq = 129.15 ± 29.28 ml/min / 1.73m2, p < 0.001). Conclusions: Our results demonstrated that CGeq overestimated, MDRDeq underestimated significantly kidney function during gestation in healthy women and cannot be recommended to assess renal function in obstetric practice. Ccr remains a useful clinical tool in pregnant women until the development of a specific equation that considers the several important maternal renal physiological alterations and provides the measure of GFR the most unbiased and precise as possible.

Research progress on the effect of oocyte smooth endoplasmic reticulum clusters on early embryo development and pregnancy outcome

With the clinical development and application of intracytoplasmic sperm injection(ICSI)technology in human assisted reproduction,the influence of oocyte quality on embryo development has been paid more and more attention.So far,there have been many reports on oocyte morphology affecting embryo development.It has been found in some works that the appearance of smooth endoplasmic reticulum clusters(SERC)in oocytes may affect the fertilization and embryo development of oocytes.However,with the increasing reports of SERC-containing oocytes obtained by in vitro fertilization and healthy offspring in recent years,there is still some controversy on whether to continue to use SERC-containing oocytes for the following assisted reproductive therapy in clinical practice.Based on this,this review aims to review the research progress of SERC in oocytes in recent years.
