The Impact of Seasonal Variation on Clinical Pregnancy and Live Birth Rates in Assisted Reproductive Technology: A Retrospective Cohort Study in Hainan

Objective:To investigate the influence of season on live birth and clinical pregnancy rates,as well as assisted reproductive technology(ART)outcomes,in the Hainan region.Methods:Patients were categorized into four groups based on the dates of artificial insemination and transplantation:spring,summer,autumn,or winter.The main outcome measures were clinical pregnancy rates and live birth rates.Secondary outcomes included body mass index(BMI),oocyte number,two pronuclei(2PN)cleavage rate,total gonadotropin(Gn)dosage and days,age,2PN fertilization rate,sperm concentration,sperm PR rate,anti-Müllerian hormone(AMH),and endometrial thickness.Outpatient semen quality indicators included sperm PR rate,total sperm count,sperm concentration,and total sperm motility.Results:This retrospective cohort study analyzed 2,016 artificial insemination cycles and 1,783 ovarian retrieval cycles from January 2017 to October 2022,and assessed the semen quality of 6,651 outpatients from May 2017 to October 2022.In artificial insemination cycles,sperm PR rate and clinical pregnancy rate were highest in winter,with a statistically significant difference between groups(P<0.05).Clinical pregnancy rate was influenced by both age and sperm PR rate(P<0.05).In ovarian retrieval cycles,the winter group had significantly higher clinical pregnancy,2PN fertilization,and 2PN cleavage rates than the other groups.The autumn group had higher live birth rates,though not significantly different.Additionally,winter months showed higher total sperm concentration and total sperm number compared to other seasons.Conclusion:Seasonality affected clinical pregnancy and live birth rates in artificial insemination cycles but not in ovarian retrieval cycles in the Hainan region.These findings suggest that while there is no need to choose a specific season for ovarian retrieval cycles,artificial insemination in winter may be preferable for patients.

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.

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.

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.

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.

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.

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.

Influence of Different Gonadotropin-releasing Hormone Agonist Administration Methods on Pregnancy Outcomes of Patients Undergoing In-vitro Fertilization-embryo Transfer

This study aimed to investigate the effect of different gonadotropin-releasing hormone agonist (GnRH-a) administration methods on pregnancy outcomes of patients undergoing in-vitro fertilization-embryo transfer (IVF-ET). Clinical data of 5217 patients who underwent IVF-ET were retrospectively analyzed. Patients were divided into the long-acting GnRH-a group (n=1330) and the short-acting GnRH-a group (w=3887) based on their various treatment plans. The clinical and laboratory embryo data and clinical pregnancy outcomes were compared between the two groups. The results showed that there were no significant differences in the age, infertility, primary/secondary infertility rate, IVF rate, body mass index (BMI), antral follicle counting (AFC), folliclestimulating hormone (FSH) level, and the number of transplanted embryos between the two groups (P>0.05). There were no significant differences in the oocyte numbers, M II rate, fertilization rate, cleavage rate and blastocyst formation rate (P>0.05) between the two groups. The gonadotropin (Gn) using days, Gn dose and endometrial thickness were significantly greater in the long-acting GnRH-a group than those in the short-acting GnRH-a group (P<0.01). Additionally, the estradiol (E2) levels, blastocyst freezing rate, embryo utilization rate, transplant cancellation rate and abortion rate were significantly lower in the long-acting GnRH-a group than those in the shortacting GnRH-a group (P<0.01). The clinical pregnancy rate and embryo implantation rate were significantly higher in the long-acting GnRH-a group than in the short-acting GnRH-a group (P<O.Ol). It was concluded that use of long-acting GnRH-a can effectively reduce the transplant cancellation rate and improve the clinical pregnancy rate of the fresh cycle.

Adjuvant acupuncture reduces first trimester pregnancy loss after IVF

Background: The objective of this study was to determine the effects of acupuncture treatment as an adjunctive therapy on the outcome of in vitro fertilization (IVF)/Intracytoplasmic Sperm Injection (ICSI). Material/Methods: We conducted a retrospective study of 238 patients who underwent conventional IVF/ ICSI alone or in conjunction with acupuncture over a course of 2 years. Patients in the two treatment groups were matched in terms of age and diagnosis. Acupuncture was administered in two sessions 5 to 7 days prior to and on the day of embryo transfer. Results: There were no differences between the two groups in terms of fertilization rate, pregnancy or implantation rates, and endometrial thickness. The number of oocytes retrieved (P < 0.005) and the number of first trimester miscarriages were significantly lower in the group receiving acupuncture (P < 0.001). Conclusions: Acupuncture reduces miscar-riage rates in patients undergoing IVF/ICSI possibly secondary to stress relief.

Effects of Medicines and Supplements on Spontaneous Pregnancy and Semen Parameters in Male Infertility:A Systematic Review Update and Network Meta-Analysis

In this study,we used a network meta-analysis(NMA)to compare the effectiveness of medicines and supplements for idiopathic male infertility and to identify the best treatment.Medline,Excerpta Medica Database(EMBASE),Ovid,and China National Knowledge Infrastructure(CNKI),were searched for the period from January 1990 to June 2021 using the keywords"male infertility,""medical therapy,""supplement/nutrient therapy,"and related terms.Randomized controlled trials(RCTs)investigating medicines(mainly follicle-stimulating hormone(FSH),androgen,and clomiphene/tamoxifen)or supplements(mainly zinc,selenium,vitamin C or E,carnitine,coenzyme Q10(CoQ10),or combined treatment)for idiopathic infertile men were selected for meta-analysis.Preferred reporting items for systematic reviews and meta-analysis(PRISMA)was used for data extraction,and a risk-of-bias tool and grades of recommendation,assessment,development,and evaluation(GRADE)system adapted to the NMA were employed to assess the quality of the evidence.The primary outcomes were live birth and spontaneous pregnancy rate(SPR).The secondary outcomes were sperm parameters(including concentration,progressive motility,and morphology)and side effects.In total,65 RCTs involving 7541 men with sperm abnormalities but normal hormone levels were included.A total of 36 studies reported SPR but only three reported live birth rates.The quality of the included studies was found to be moderate to high.Compared with a placebo or being untreated,carnitine plus vitamins significantly improved SPR(relative risk(RR)=3.7,95%confidence interval(95%CI),1.6-8.5);fatty acids significantly increased sperm concentrations(mean difference(MD)=12.5×10^(6)mL-1,95%CI,3.1×10^(6)-22.0×10^(6));and selective estrogen receptor modulator(SERM)plus CoQ10 significantly improved sperm progressive motility(MD=11.0%,95%CI,0.1%-21.9%)and normal sperm morphology(MD=11.0%,95%CI,4.6%-17.4%).The most optimal intervention was carnitine plus vitamins and fatty acids for SPR and sperm concentrations,respectively,even after excluding trials at a high risk of bias.Compared with a placebo or being untreated,FSH(RR=4.9,95%CI,1.1-21.3)significantly increased SPR,whereas SERM plus kallikrein increased sperm concentration(MD=16.5×10^(6)mL^(-1),95%CI,1.6×10^(6)-31.4×10^(6)),and SERM plus CoQ10 significantly improved sperm progressive motility(MD=11.3%,95%CI,7.3%-15.4%)and normal morphology(MD=11.2%,95%CI,5.4%-16.9%)in men with oligoasthenozoospermia(OA).In terms of side effects,fatty acids and pentoxifylline were associated with foul breath and/or a bad taste(RR=8.1,95%CI,1.0-63.5)and vomiting(RR=8.0,95%CI,1.0-63.0),respectively.In conclusion,the optimal treatment for male infertility for live birth is still unknown.Carnitine plus vitamins and FSH are likely to be better than other therapies in achieving successful spontaneous pregnancy in couples overall and in cou ples with men with OA,respectively.The efficacy of other treatments on pregnancy outcomes warrants further verification.

Impact of Serum Progesterone Levels in GnRH Antagonist Assisted Reproduction Cycles on Pregnancy Outcomes: A Prospective Cohort Study

Background: With controlled ovarian hyperstimulation (COH) with gonadotrophin releasing hormone (GnRH) antagonists, sometimes it is associated with incomplete luteolysis leading to elevated serum progesterone in early follicular phase. Persistence of this elevation might reduce the chance for clinical pregnancy. Objective: To assess the effect of elevated early and late follicular progesterone (P) levels during gonadotrophins releasing hormone (GnRH) antagonist cycles on pregnancy outcome. Design: Prospective single center study. Setting: North-western Military hospital, Kingdom of Saudi Arabia. Patients: 302 in vitro fertilization/intra-cytoplasmic sperm injection (IVF-ICSI) patients. Intervention(s): Recombinant follicle stimulating hormone (r-FSH), (150 - 300 IU) started daily from cycle day 2;GnRH antagonist treatment started on day 6 of the cycle. The serum progesterone (P) measured twice on cycle day 2 and human chorionic gonadotrophin (hCG) day. Main Outcome Measures: Clinical pregnancy and live birth rates per started cycle. Results: The incidence of elevated serum P on day 2 was (5.3%) and on hCG day was (17.5%), statistically significant differences in clinical pregnancy rate (32.3% versus 13.0%) and in live birth rate (23.4% versus 11.1%) were present between the normal and high serum progesterone groups on hCG day, but these differences were not statistically significant in the groups of elevated basal progesterone. Conclusion: Follicular phase progesterone rise either on day 2 or the day of hCG trigger was associated with lower clinical pregnancy and live birth rates. This impact was more prominent with trigger day elevation.

First Trimester Pregnancy Loss May Temporary Reduce the Ovarian Response during the Subsequent IVF Cycle

The aim of this study was to compare the in vitro fertilization (IVF) cycles ended by miscarriage with subsequent IVF cycles in relation to various IVF cycle parameters and pregnancy termination modalities. Comparison of pre-miscarriage to post-miscarriage IVF cycles parameters demonstrated that lower peak E2 levels (1087 ± 593 versus 1237 ± 676 pg/ml, respectively;p p p p p p < 0.05), and an increase in the conception rate (34.7% versus 42.2%, respectively) at the second post-miscarriage IVF cycle.

Can Chinese herbal medicine improve the pregnancy outcomes of patients with poor ovarian response?—a systematic review and meta-analysis of randomized controlled trials

Poor response to ovarian stimulation which results in low pregnancy rate has been a major challenging in assisted reproductive technology.Chinese herbal medicine(CHM)has been used as a supplementary or an alternative intervention in improving pregnancy rate in women with poor ovarian response(POR).This systematic review was aimed to assess the clinical effectiveness of Chinese herbal medicine for the treatment of POR.We searched Embase,PubMed,China National Knowledge Infrastructure(CNKI),VIP Database,Chinese biomedical database(CBM),Wan Fang database and the Cochrane library from January 2011 to March 2018.Study quality assessment and metaanalyses were performed according to the Cochrane recommendations.16 trials including 1245 ovulation-promoting cycles were evaluated.The analysis showed that CHM can increase the pregnancy rate(RR=1.80,95%CI(1.41-2.29),P<0.001),while decrease cycle cancellation(RR=0.66,95%CI(0.45-0.97),P=0.04).Conclusion:CHM presented a promising effectiveness in women with POR as a supplementary or an alternative intervention in IVF/ICSI.

补肾化痰活血方治疗多囊卵巢综合征合并胰岛素抵抗不孕症的临床研究

[目的]观察补肾化痰活血方治疗多囊卵巢综合征合并胰岛素抵抗(PCOS-IR)不孕症的临床疗效。[方法]将62例肾虚痰瘀型PCOS-IR不孕症患者随机分为治疗Ⅰ组和治疗Ⅱ组,每组各31例。两组均给予基础干预,治疗Ⅰ组给予二甲双胍,治疗Ⅱ组给予补肾化痰活血方,治疗及随访周期均为3个月。统计两组的妊娠及排卵情况,比较两组治疗前后身体质量指数(BMI)、中医证候积分、糖代谢指标[空腹血糖(FBG)、空腹胰岛素(FINS)、胰岛素抵抗指数(HOMA-IR)]、性激素水平[睾酮(T)、促黄体生成素(LH)、促卵泡刺激素(FSH)、LH/FSH、雌二醇(E2)、催乳素(PRL)]、着床期(排卵后6~9 d)子宫内膜三维超声参数[厚度、分型、容积、血管化指数(VI)、血流指数(FI)、血管化-血流指数(VFI)]和不良反应。[结果]与治疗前比较,治疗后两组的BMI、中医证候积分、FINS、HOMA-IR、LH、LH/FSH水平均降低(P<0.01或P<0.05),且治疗Ⅱ组的中医证候积分降低显著(P<0.01)。与治疗Ⅰ组比较,治疗Ⅱ组的周期排卵率较高,但比较后差异无统计学意义(P>0.05),着床期子宫内膜血流参数VI、VFI水平较高(P<0.05)。治疗结束及随访后,治疗Ⅱ组的临床妊娠率分别为61.54%(16/26)和73.08%(19/26),明显高于治疗Ⅰ组对应时间节点的妊娠率[33.33%(8/24)和41.67%(10/24)],差异有统计学意义(P<0.05),且胚胎停育率更低(P<0.05)。治疗Ⅱ组的不良反应率显著低于治疗Ⅰ组(15.38%vs 41.67%,P<0.05)。[结论]补肾化痰活血方治疗肾虚痰瘀型PCOS-IR不孕症临床效果良好,能够改善胰岛素抵抗及肥胖体征,调节内分泌紊乱,显著增加着床期子宫内膜血流灌注,提高临床妊娠率并改善妊娠结局,且不良反应小,值得推广应用。
