Objective

To characterize the growth factor midkine (MDK) in the human ovary to determine whether MDK is produced locally within the ovary, examine whether different ovarian cell types are more likely to produce MDK, and determine whether there are any stage-specific variations during follicle growth. Previous studies have revealed that MDK potentially affects human follicle growth and oocyte maturation. Proteomic analyses in follicular fluid (FF) have identified MDK to functionally cluster together and follow a similar expression profile to that of well-known proteins involved in ovarian follicle development. Midkine has not yet been characterized in the human ovary.

Design

Descriptive study.

Setting

University Hospital.

Patients

The study included samples from 121 patients: 71 patients (aged 17–37 years) who underwent ovarian tissue cryopreservation provided granulosa cells (GC), cumulus cells, ovarian cortex, medulla tissue, and FF from small antral follicles (SAF); and 50 patients (aged 20–35 years) receiving in vitro fertilization treatment provided FF from preovulatory follicles before and after induction of final follicle maturation.

Interventions

None.

Main Outcome Measures

MDK relative gene expression was quantified using a real-time quantitative polymerase chain reaction in cumulus cells, GC, and medulla tissue. Additionally, immunostaining and western blotting assays were used to detect MDK protein in the ovarian cortex, which contains preantral follicles, SAF, and medulla tissue. Furthermore, enzyme-linked immunosorbent assay analyses were performed to measure the concentration of MDK in FF aspirated from SAF and preovulatory follicles both before and 36 hours after inducing the final maturation of follicles.

Results

Immunostaining and reverse transcription-quantitative polymerase chain reaction revealed a more prominent expression of MDK in GC compared with other ovarian cell types. Intrafollicular MDK concentration was significantly higher in SAF compared with preovulatory follicles. In addition, different molecular weight species of MDK were detected using western blotting in various ovarian sample types: GC and FF samples presented primarily one band of approximately 15 kDa and an additional band of approximately 13 kDa, although other bands with higher molecular weight (between 30 and 38 kDa) were detected in medulla tissue.

Conclusions

This is the first time that MDK has been immunolocalized in human ovarian cells at the protein level and that potentially different MDK variants have been detected in human FF, GC, and ovarian medulla tissue. Future studies are needed to sequence and identify the different potential MDK variants

目的:鉴定人卵巢中的生长因子-中间因子(MDK),以确定MDK是否在卵巢内局部产生;ii)检查不同的卵巢细胞类型是否更有可能产生MDK;iii)以及卵泡生长过程中是否存在任何阶段特异性变化。先前的研究表明,MDK可能影响人类卵泡生长和卵母细胞成熟。卵泡液(FF)中的蛋白质组学分析已经确定MDK在功能上聚集在一起,并遵循与已知的参与卵泡发育的蛋白质相似的表达谱。MDK尚未在人类卵巢中得到表征。设计:描述性研究单位:大学医院。患者:该研究包括121名患者的样本:71名接受卵巢组织冷冻保存(OTC)的患者(年龄17-37岁)提供了来自小窦卵泡(SAF)的颗粒细胞(GC)、卵丘细胞(CC)、卵巢皮质、髓质组织和FF;50名接受体外受精(IVF)治疗的患者(年龄20-35岁)在诱导卵泡最终成熟前后从排卵前卵泡提供FF。干预措施:无主要观察指标:通过RT-qPCR定量CC、GC和髓质组织中MDK相关基因的表达。此外,免疫染色和western印迹分析用于检测含有腔前卵泡、SAF和髓质组织的卵巢皮质中的MDK蛋白。此外,在诱导卵泡最终成熟之前和之后36小时,进行ELISA分析以测量从SAF和排卵前卵泡抽吸的FF中MDK的浓度。结果:免疫染色和RT-qPCR显示,与其他卵巢细胞类型相比,MDK在GC中的表达更为显著。SAF卵泡内MDK浓度明显高于排卵前卵泡。此外,通过蛋白质印迹在各种卵巢样品类型中检测到不同分子量(Mw)的MDK:GC和FF样品主要呈现一条约15kDa的带和一条约13kDa的附加带,而在髓质组织中检测到其他Mw较高的带(在30和38kDa之间)。结论:这是MDK首次在人卵巢细胞中进行蛋白水平的免疫定位,并且在人FF、GC和卵巢髓质组织中检测到潜在的不同MDK变体。未来的研究需要对发现的不同潜在MDK变体进行测序和鉴定,以确定其对卵巢和卵母细胞能力的功能重要性。

Objective

Vilaprisan is a highly potent selective progesterone receptor modulator shown to reduce heavy menstrual bleeding, induce amenorrhea, and diminish uterine fibroid volume in phase 2 studies. The objective of ASTEROID 3 was to demonstrate the superiority of vilaprisan compared with placebo in the treatment of heavy menstrual bleeding in women with uterine fibroids.

Design

Randomized, double-blind, placebo-controlled, multicenter phase 3 study.

Setting

Hospitals and medical centers.

Patient(s)

Women with ≥1 uterine fibroid of ≥3 cm and heavy menstrual bleeding of >80 mL/cycle.

Intervention(s)

Women were randomly assigned to 1 of 4 treatment arms, which were planned to comprise 2 treatment periods of 12 weeks, each with vilaprisan (2 mg/d) or placebo that were continuous or separated by a break of one bleed.

Main Outcome Measure(s)

Amenorrhea (primary end point; <2 mL in the last 28 days of treatment) and heavy menstrual bleeding response (key secondary end point; <80 mL/cycle and >50% reduction in bleeding from baseline) were measured with the alkaline hematin method. Change in volume of the 3 largest fibroids from baseline to end of treatment was assessed by ultrasound. Safety was monitored throughout the study.

Result(s)

Overall, 75 women completed the first 12 weeks of treatment. Statistically significant and clinically meaningful differences were observed between the vilaprisan- and placebo-treated groups in both the full analysis and per-protocol sets. In the per-protocol set (n = 36 and n = 12 for the vilaprisan and placebo groups, respectively), amenorrhea was observed more frequently in women treated with vilaprisan than in those who received placebo (83.3% vs. 0%, P<.0001), with a median time to onset of 3 days in the vilaprisan group. Similarly, more vilaprisan- than placebo-treated women achieved a response in heavy menstrual bleeding (91.7% vs. 25.0%, P<.0001). Serious adverse events were reported for 22 (27.8%) of 79 women and were evenly distributed among the 4 groups receiving vilaprisan and/or placebo. None of these events led to study discontinuation or were related to the liver, and no new safety findings were identified compared with the earlier phase 2 ASTEROID studies.

Conclusion(s)

Vilaprisan is efficacious and well tolerated over 12 weeks in the treatment of heavy menstrual bleeding associated with uterine fibroids. Further investigations of the long-term efficacy and safety of vilaprisan are warranted.

Clinical Trial Registration Number

NCT03400943 (ClinicalTrials.gov).

Objective

To investigate the power of DNA methylation variability in sperm cells in assessing male fertility potential.

Design

Retrospective cohort.

Setting

Fertility care centers.

Patients

Male patients seeking infertility treatment and fertile male sperm donors.

Intervention

None.

Main Outcome Measures

Sperm DNA methylation data from 43 fertile sperm donors were analyzed and compared with the data from 1344 men seeking fertility assessment or treatment. Methylation at gene promoters with the least variable methylation in fertile patients was used to create 3 categories of promoter dysregulation in the infertility treatment cohort: poor, average, and excellent sperm quality.

Results

After controlling for female factors, there were significant differences in intrauterine insemination pregnancy and live birth outcomes between the poor and excellent groups across a cumulative average of 2–3 cycles: 19.4% vs. 51.7% (P=.008) and 19.4% vs. 44.8% (P=.03), respectively. Live birth outcomes from in vitro fertilization, primarily with intracytoplasmic sperm injection, were not found to be significantly different among any of the 3 groups.

Conclusion

Methylation variability in a panel of 1233 gene promoters could augment the predictive ability of semen analysis and be a reliable biomarker for assessing intrauterine insemination outcomes. In vitro fertilization with intracytoplasmic sperm injection appears to overcome high levels of epigenetic instability in sperm.

目的:研究精子细胞DNA甲基化变异性在评估男性生育潜力中的作用。设计:回顾性队列。设置:生育护理中心。患者:寻求不孕不育治疗的男性患者和可生育的男性精子捐献者。干预:无。主要结果指标:分析43名可生育精子捐献者的精子DNA甲基化数据,并将其与1344名寻求生育评估或治疗的男性的数据进行比较。在不孕不育治疗队列中,使用可生育患者中甲基化变化最小的基因启动子甲基化来产生3类启动子失调:精子质量差、平均和优秀。结果:在控制了女性因素后,在累计平均2-3个周期内,贫穷组和优秀组在宫内受精妊娠和活产结局方面存在显著差异:分别为19.4%和51.7%(P=0.008)以及19.4%和44.8%(P=0.03)。体外受精(主要是卵浆内精子注射)的活产结果在三组中没有发现显著差异。结论:1233个基因启动子的甲基化变异性可以增强精液分析的预测能力,并成为评估宫内受精结果的可靠生物标志物。卵浆内精子注射的体外受精似乎可以克服精子中高水平的表观遗传不稳定性。

Objective

To develop a spatiotemporal model for de prediction of euploid and aneuploid embryos using time-lapse videos from 10–115 hours after insemination (hpi).

Design

Retrospective study.

Main Outcome Measures

The research used an end-to-end approach to develop an automated artificial intelligence system capable of extracting features from images and classifying them, considering spatiotemporal dependencies. A convolutional neural network extracted the most relevant features from each video frame. A bidirectional long short-term memory layer received this information and analyzed the temporal dependencies, obtaining a low-dimensional feature vector that characterized each video. A multilayer perceptron classified them into 2 groups, euploid and noneuploid.

Results

The model performance in accuracy fell between 0.6170 and 0.7308. A multi-input model with a gate recurrent unit module performed better than others; the precision (or positive predictive value) is 0.8205 for predicting euploidy. Sensitivity, specificity, F1-Score and accuracy are 0.6957, 0.7813, 0.7042, and 0.7308, respectively.

Conclusions

This article proposes an artificial intelligence solution for prioritizing euploid embryo transfer. We can highlight the identification of a noninvasive method for chromosomal status diagnosis using a deep learning approach that analyzes raw data provided by time-lapse incubators. This method demonstrated potential automation of the evaluation process, allowing spatial and temporal information to encode.

To investigate the link between EZH2 and Wnt/β-catenin signaling and its role in uterine fibroids (UFs) pathogenesis and explore the potential effect of natural compound methyl jasmonate (MJ) against UFs.

Design

EZH2 overexpression or inhibition was achieved in human uterine leiomyoma (HuLM) cells using EZH2-expressing adenovirus or chemical EZH2 inhibitor (DZNep), respectively. The HuLM and normal uterine smooth muscle cells were treated with 0.1–3 mM of MJ, and several experiments were employed.

Setting

Laboratory study.

Patients(s)

None.

Intervention(s)

Methyl jasmonate.

Main Outcome Measure(s)

Protein expression of EZH2, β-catenin, and proliferating cell nuclear antigen (PCNA) was measured by Western blot as well as gene expression alterations of Wnt ligands (Wnt5A, Wnt5b, and Wnt9A), WISP1, CTNNB1, and its responsive gene PITX2 using quantitative real-time polymerase chain reaction. The protein and ribonucleic acid (RNA) levels of several markers were measured in MJ-treated or untreated HuLM cells, including EZH2 and β-catenin, extracellular matrix markers collagen type 1 (COL1A1) and fibronectin (FN), proliferation markers cyclin D1 (CCND1) and PCNA, tumor suppressor marker p21, and apoptotic markers (BAX, cytochrome c, and cleaved caspase 3).

Result(s)

EZH2 overexpression significantly increased the gene expression of several Wnt ligands (PITX2, WISP1, WNT5A, WNT5B, and WNT9A), which increased nuclear translocation of β-catenin and PCNA and eventually HuLM cell proliferation. EZH2 inhibition blocked Wnt/β-catenin signaling activation where the aforementioned genes significantly decreased as well as PCNA, cyclin D1, and PITX2 protein expression compared with those in untreated HuLM. Methyl jasmonate showed a potent antiproliferative effect on HuLM cells in a dose- and time-dependent manner. Interestingly, the dose range (0.1–0.5 mM) showed a selective growth inhibitory effect on HuLM cells, not on normal uterine smooth muscle cells. Methyl jasmonate treatment at 0.5 mM for 24 hours significantly decreased both protein and RNA levels of EZH2, β-catenin, COL1A1, FN, CCND1, PCNA, WISP1, and PITX2 but increased the protein levels of p21, BAX, cytochrome, c and cleaved caspase 3 compared with untreated HuLM. Methyl jasmonate–treated cells exhibited down-regulation in the RNA expression of 36 genes, including CTNNB1, CCND1, Wnt5A, Wnt5B, and Wnt9A, and up-regulation in the expression of 34 genes, including Wnt antagonist genes WIF1, PRICKlE1, and DKK1 compared with control, confirming the quantitative real-time polymerase chain reaction results.

Conclusion(s)

Our studies provide a novel lin

目的:研究EZH2和Wnt/β-catenin信号传导之间的联系及其在子宫肌瘤(UFs)发病机制中的作用,探讨天然化合物茉莉酸甲酯(MJ)对UFs的潜在作用。HuLM和正常子宫平滑肌细胞用0.1-3mM MJ处理,并进行了几个实验。设置:实验室研究。患者:无。干预:茉莉酸甲酯。主要结果测量:通过Western印迹测量EZH2、β-连环蛋白和增殖细胞核抗原(PCNA)的蛋白表达,以及使用定量实时聚合酶链反应测量Wnt配体(Wnt5A、Wnt5b和Wnt9A)、WISP1、CTNNB1及其应答基因PITX2的基因表达变化。在MJ处理或未处理的HuLM细胞中测量了几种标志物的蛋白质和核糖核酸(RNA)水平,包括EZH2和β-连环蛋白,细胞外基质标志物1型胶原(COL1A1)和纤连蛋白(FN),增殖标志物细胞周期蛋白D1(CCND1)和PCNA,肿瘤抑制标志物p21,结果:EZH2过表达显著增加了几种Wnt配体(PITX2、WISP1、WNT5A、WNT5B和WNT9A)的基因表达,从而增加了β-连环蛋白和PCNA的核转位,最终导致HuLM细胞增殖。EZH2抑制阻断了Wnt/β-catenin信号传导激活,与未治疗的HuLM相比,上述基因以及PCNA、细胞周期蛋白D1和PITX2蛋白表达显著降低。茉莉酸甲酯以剂量和时间依赖的方式对HuLM细胞显示出强大的抗增殖作用。有趣的是,剂量范围(0.1-0.5mM)对HuLM细胞显示出选择性生长抑制作用,而不是对正常子宫平滑肌细胞。与未处理的HuLM相比,0.5mM茉莉酸甲酯处理24小时显著降低了EZH2、β-连环蛋白、COL1A1、FN、CCND1、PCNA、WISP1和PITX2的蛋白质和RNA水平,但增加了p21、BAX、细胞色素、c和裂解的胱天蛋白酶3的蛋白质水平。与对照相比,茉莉酸甲酯处理的细胞表现出36个基因的RNA表达下调,包括CTNNB1、CCND1、Wnt5A、Wnt5B和Wnt9A,34个基因的表达上调,包括Wnt拮抗剂基因WIF1、PRICKlE1和DKK1,证实了定量实时聚合酶链反应的结果。结论:我们的研究提供了EZH2与UFs中Wnt/β-catenin信号通路之间的新联系。在我们的模型中,MJ靶向EZH2干扰wnt/β-catenin信号的激活。茉莉酸甲酯可能提供一种有前景的治疗选择,作为一种针对不明飞行物的非完整且具有成本效益的治疗方法,具有良好的临床实用性,有待在人体临床试验中证明安全有效。

Objective

To study the relationship between the steroid concentration in the endometrium, in serum, and the gene expression level of steroid-metabolizing enzymes in the context of endometrial receptivity in in vitro fertilization (IVF) patients.

Design

Case-control study of 40 IVF patients recruited in the SCRaTCH study (NTR5342), a randomized controlled trial investigating pregnancy outcome after “endometrial scratching.” Endometrial biopsies and serum were obtained from patients with a first failed IVF cycle randomized to the endometrial scratch in the midluteal phase of the natural cycle before the next fresh embryo transfer during the second IVF cycle.

Setting

University hopsital.

Patients

Twenty women with clinical pregnancy were compared with 20 women who did not conceive after fresh embryo transfer. Cases and controls were matched for primary vs. secondary infertility, embryo quality, and age.

Intervention

None.

Main Outcome Measure(s)

Steroid concentrations in endometrial tissue homogenates and serum were measured with liquid chromatography-mass spectrometry. The endometrial transcriptome was profiled by RNA-sequencing, followed by principal component analysis and differential expression analysis. False discovery rate-adjusted and log-fold change >|0.5| were selected as the threshold for differentially expressed genes.

Result(s)

Estrogen levels were comparable in both serum (n = 16) and endometrium (n = 40). Androgens and 17-hydroxyprogesterone were higher in serum than that in endometrium. Although steroid levels did not vary between pregnant and nonpregnant groups, subgroup analysis of primary women with infertility showed a significantly lower estrone concentration and estrone:androstenedione ratio in serum of the pregnant group (n = 5) compared with the nonpregnant group (n = 2). Expression of 34 out of 46 genes encoding the enzymes controlling the local steroid metabolism was detected, and estrogen receptor β gene was differentially expressed between pregnant and nonpregnant women. When only the primary infertile group was considered, 28 genes were differentially expressed between pregnant and nonpregnant women, including HSD11B2, that catalyzes the conversion of cortisol into cortisone.

Conclusion(s)

Steroidomic and transcriptomic analyses show that steroid concentrations are regulated by the local metabolism in the endometrium. Although no differences were found in endometrial steroid concentration in the pregnant and nonpregnant IVF patients, primary women with infertility showed deviations in steroid levels and gene expression, indicating that a more homogeneous patient group is required to uncover the exact role of steroid metabolism in endometrial receptivity.

Objective

To study the relationship between the seminal sample quality of men with varicocele and sperm capacitation.

Design

Cross-sectional observational study.

Setting

Academic hospital.

Patient(s)

Seventy-six men (19 control and 57 with varicocele) were analyzed.

Intervention(s)

Semen samples were submitted to a discontinuous density gradient for sperm selection. Sperm capacitation was induced using a human tubal fluid medium supplemented with bovine serum albumin.

Main Outcome Measure(s)

After capacitation induction, the sperm were assessed by capacitation state, computer-assisted sperm motility, mitochondrial activity, membrane integrity, acrosome reaction, and intracellular oxidative stress.

Result(s)

The capacitation period increased sperm motility, showing an increase in the average path velocity and a decrease in the straightness compared with sperm before capacitation (paired analysis). After capacitation, the rate of capacitated sperm, motility, and mitochondrial activity showed differences between groups (control and varicocele). The varicocele group showed lower mitochondrial activity and capacitation than the control group. On the other hand, no significant differences were observed in the other variables evaluated.

Conclusion(s)

Varicocele men showed less viable sperm and mitochondrial activity than control men after capacitation sperm. The induction of capacitation altered motility by increasing path velocity and decreasing straightness in all of the studied groups, evidencing the occurrence of hyperactivation.

目的探讨男性精索静脉曲张精液样本质量与精子获能的关系。设计横断面观察性研究。设置学术医院。对76名男性患者(19名对照组和57名精索静脉曲张患者)进行了分析。干预精液样本采用不连续密度梯度进行精子选择。使用补充有牛血清白蛋白的人输卵管液体培养基诱导精子获能。主要结果指标获能诱导后,通过获能状态、计算机辅助精子活力、线粒体活性、膜完整性、顶体反应和细胞内氧化应激来评估精子。结果获能期增加了精子的活力,与获能前相比,平均路径速度增加,直线度降低(配对分析)。获能后,各组(对照组和精索静脉曲张组)的精子获能率、活力和线粒体活性存在差异。精索静脉曲张组的线粒体活性和获能能力低于对照组。另一方面,在评估的其他变量中没有观察到显著差异。结论精索静脉曲张男性获能后精子活力和线粒体活性低于对照男性。在所有研究组中,获能的诱导通过增加路径速度和降低直线度来改变运动,证明了过度激活的发生。

Objective

To determine the mechanistic role of mobile genetic elements in causing widespread DNA damage in primary human trophoblasts.

Design

Experimental ex vivo study.

Setting

Hospital-affiliated University.

Patient(s)

Trophoblasts from a patient with unexplained recurrent pregnancy loss and patients with spontaneous and elective abortions (n = 10).

Intervention(s)

Biochemical and genetic analysis and modification of primary human trophoblasts.

Main Outcome Measure(s)

To phenotype and systematically evaluate the underlying pathogenic mechanism for elevated DNA damage observed in trophoblasts derived from a patient with unexplained recurrent pregnancy loss, transcervical embryoscopy, G-band karyotyping, RNA sequencing, quantitative polymerase chain reaction, immunoblotting, biochemical and siRNA assays, and whole-genome sequencing were performed.

Result(s)

Transcervical embryoscopy revealed a severely dysmorphic embryo that was euploid on G-band karyotyping. RNA sequencing was notable for markedly elevated LINE-1 expression, confirmed with quantitative polymerase chain reaction, and that resulted in elevated expression of LINE-1-encoded proteins, as shown by immunoblotting. Immunofluorescence, biochemical and genetic approaches demonstrated that overexpression of LINE-1 caused reversible widespread genomic damage and apoptosis.

Conclusion(s)

Derepression of LINE-1 elements in early trophoblasts results in reversible but widespread DNA damage.

目的确定可移动遗传元件在原代人类滋养层细胞中引起广泛DNA损伤的机制作用。设计实验性离体研究。SettingHospital附属大学。不明原因复发性流产患者和自然流产和选择性流产患者的滋养层(n=10)。干预措施。原代人类滋养层的生化和基因分析及修饰。主要结果测量表型并系统评估在不明原因复发性流产患者滋养层中观察到的DNA损伤升高的潜在致病机制,经宫颈胚胎检查,G带核型分析,RNA测序,定量聚合酶链式反应,免疫印迹,生物化学和siRNA测定,并进行全基因组测序。结果经宫颈胚胎检查发现一个严重畸形的胚胎,G带核型为整倍体。RNA测序显著提高了LINE-1的表达,定量聚合酶链式反应证实了这一点,并导致LINE-1编码蛋白的表达增加,如免疫印迹所示。免疫荧光、生物化学和遗传学方法表明,LINE-1的过表达导致可逆的广泛基因组损伤和细胞凋亡。结论早期滋养层细胞LINE-1元件的表达减少可导致可逆但广泛的DNA损伤。

Objective

To evaluate whether the effect of de novo mutated balanced reciprocal translocation on the rate of euploid embryos varied from inherited balanced reciprocal translocation.

Design

A retrospective cohort study compared the percentage of euploid embryo and proportion of patients with at least 1 euploid embryo between de novo mutated balanced reciprocal translocation (i.e., the group of de novo mutated carriers) and inherited balanced reciprocal translocation (i.e., the group of inherited carriers).

Setting

An academic fertility center.

Patient(s)

A total of 413 couples with balanced reciprocal translocation (219 female carriers and 194 male carriers) who underwent their first cycle of preimplantation genetic testing for structural rearrangements were included.

Intervention(s)

Carriers of balanced reciprocal translocation either de novo mutated or inherited.

Main Outcome Measure(s)

The percentage of euploid embryo and proportion of patients with at least 1 euploid embryo.

Result(s)

The carriers of the de novo mutated balanced reciprocal translocation had a lower percentage of euploid embryos (19.5% vs. 25.5%), and were less likely to have at least 1 euploid embryo (47.1% vs. 60.1%) compared with the carriers of the inherited balanced reciprocal translocation. In the male-carrier subgroup, the percentage of euploid embryos (16.7% vs. 26.7%) and proportion of patients with at least 1 euploid embryo (41.9% vs. 67.5%) were lower among the de novo mutated carriers than those among the inherited carriers. However, in the female-carrier subgroup, there was no statistically significant difference in the percentage of euploid embryos (22.4% vs. 24.4%) or the proportion of patients with at least 1 euploid embryo (52.3% vs. 53.7%) between the de novo mutated carriers and inherited carriers.

Conclusion(s)

The de novo mutated balanced reciprocal translocation was associated with a lower percentage of euploid embryos and lower chance of obtaining at least 1 euploid embryo than the inherited balanced reciprocal translocation.

目的评价新突变平衡互惠易位对整倍体胚胎率的影响是否与遗传平衡互惠易位不同。设计一项回顾性队列研究比较了新突变的平衡互惠易位(即新突变携带者组)和遗传的平衡互惠移位(即遗传携带者组)之间的整倍体胚胎的百分比和至少有1个整倍体胚的患者比例。设置一个学术生育中心。患者共包括413对具有平衡相互易位的夫妇(219名女性携带者和194名男性携带者),他们接受了植入前第一周期的结构重排基因测试。干预:新突变或遗传的平衡相互易位携带者。主要结果指标整倍体胚胎的百分比和至少有1个整倍体胚的患者比例。结果与遗传性平衡互惠易位携带者相比,新突变平衡互惠易位的携带者具有较低的整倍体胚胎百分比(19.5%对25.5%),并且不太可能具有至少1个整倍体胚(47.1%对60.1%)。在男性携带者亚组中,新突变携带者的整倍体胚胎百分比(16.7%对26.7%)和至少有1个整倍体胚的患者比例(41.9%对67.5%)低于遗传携带者。然而,在女性携带者亚组中,新突变携带者和遗传携带者的整倍体胚胎百分比(22.4%对24.4%)或至少有1个整倍体胚的患者比例(52.3%对53.7%)没有统计学上的显著差异。结论与遗传性平衡反向易位相比,新突变的平衡反向易位与较低的整倍体胚胎百分比和获得至少1个整倍体胚的机会有关。
