目的：探讨不同时机宫腔镜检查对反复胚胎移植未孕患者后续体外受精-胚胎移植（IVF-ET）临床妊娠结局的影响。方法：回顾性分析2025年1月至2025年10月于东莞康华医院生殖医学科就诊的206例行IVF-ET助孕研究对象的临床资料。根据宫腔镜检查时机分为三组：A组（胚胎移植前检查，n=82）、B组（胚胎移植1次失败后检查，n=70）、C组（胚胎移植2次失败后检查，n=54）。比较三组研究对象后续IVF-ET周期的临床妊娠率。结果：三组研究对象基线年龄、不孕年限、BMI、AMH等指标差异无统计学意义（P>0.05）。总人群临床妊娠率为53.59%（97/206），其中A组妊娠率为72.0%（59/82），B组为35.7%（25/70），C组为24.1%（13/54），组间差异有统计学意义（P<0.001）。免疫双染阳性研究对象占86.27%（176/206），其在组间分布均衡，未改变主要结论。结论：对于IVF-ET助孕研究对象，胚胎移植前进行宫腔镜检查并处理异常，可能与后续临床妊娠率升高相关；延迟至1次或2次胚胎移植失败后再检查，妊娠获益可能大幅降低。提示胚胎移植前常规行宫腔镜评估的必要性。

Objective: To investigate the impact of different timing of hysteroscopy on the subsequent clinical pregnancy outcomes of patients with recurrent embryo transfer failure undergoing in vitro fertilization - embryo transfer (IVF-ET). Methods: The clinical data of 206 patients who underwent IVF-ET assisted pregnancy treatment at the Reproductive Medicine Department of Dongguan Kanghua Hospital from January 2025 to October 2025 were retrospectively analyzed. The patients were divided into three groups based on the timing of hysteroscopy: Group A (examined before embryo transfer, n = 82), Group B (examined after one failed embryo transfer, n = 70), and Group C (examined after two failed embryo transfers, n = 54). The clinical pregnancy rates of the subsequent IVF-ET cycles of the three groups were compared. Results: There were no statistically significant differences in baseline age, duration of infertility, BMI, AMH, etc. among the three groups (P > 0.05). The overall clinical pregnancy rate of the population was 53.59% (97/206), with the pregnancy rates in Group A being 72.0% (59/82), in Group B 35.7% (25/70), and in Group C 24.1% (13/54). The differences among the groups were statistically significant (P < 0.001). Immunobright staining positive study subjects accounted for 86.27% (176/206), and their distribution among the groups was balanced, without changing the main conclusion. Conclusion: For patients undergoing IVF-ET assisted pregnancy treatment, performing hysteroscopy and treating abnormalities before embryo transfer may be associated with an increased subsequent clinical pregnancy rate; delaying the examination until one or two failed embryo transfers may significantly reduce the pregnancy benefit. It suggests the necessity of routine hysteroscopy assessment before embryo transfer.

      目的  探讨精子DNA碎片指数（DFI）对体外受精-胚胎移植（IVF-ET）胚胎发育及妊娠结局的影响，为优化男性生育力评估及辅助生殖治疗策略提供依据。方法  回顾性分析2023年1月—2024年1月于徐州市妇幼保健院接受IVF-ET治疗的126对不孕夫妇，根据男方DFI检测结果分为低碎片组（DFI≤15%，n=42）、临界组（15%＜DFI＜30%，n=45）和高碎片组（DFI≥30%，n=39）。比较三组患者受精相关指标、胚胎发育指标及妊娠结局指标的差异，并分析DFI与各指标的相关性。结果  低碎片组双原核率（2PN）率、优质胚胎率及囊胚形成率均高于临界组和高碎片组（P＜0.001），低碎片组1PN率、多PN率均低于临界组和高碎片组（P＜0.001）；三组种植率、临床妊娠率、早期流产率比较差异无统计学意义（P＞0.05），但高碎片组活产率低于低碎片组（P＜0.05）。相关性分析结果表明，DFI与优质胚胎率（r=-0.412，P＜0.001）、囊胚形成率（r=-0.387，P＜0.001）、活产率（r=-0.287，P=0.012）呈负相关，与早期流产率（r=0.206，P=0.059）、种植率（r=-0.215，P=0.058）、临床妊娠率（r=-0.203，P=0.072）无显著相关性。结论  精子DNA碎片指数是影响IVF-ET胚胎发育及妊娠结局的重要因素，高DFI主要通过降低胚胎发育潜能及增加流产风险导致活产率下降，临床需对高DFI患者进行干预以改善治疗结局。

According to duration of pregnancy, they were divided into 28 cases of early pregnancy group (gestational weeks<14 weeks), 29 cases of middle pregnancy group (14~28 weeks) and 33 cases of late pregnancy group (29~42 weeks). The vaginal or cervical secretions were collected, and genital tract flora was detected. The genital tract flora distribution of three groups were compared. According to bacteria detection results, patients were divided into 44 cases of positive group and 46 cases of negative group. The adverse pregnancy outcomes of two groups were observed, and the correlation between change characteristics of pregnant genital tract flora and adverse pregnancy outcomes was analyzed. Results Among 90 pregnant women, there were 44 cases of positive bacteria (48.89%), which included 20 cases of ureaplasma urealyticum(45.45%), 9 cases of Candida (20.45%), 8 cases of enterobacter (18.18%), 3 cases of staphylococcus (6.82%), 2 cases of vaginal gardnerella (4.55%) and 2 cases of chlamydia (4.55%); There was no statistical difference in the genital tract flora distribution among early, middle, late pregnancy group (P>0.05); The incidence of premature rupture of membrane, puerperal infection, neonatal infection and premature birth in patients with positive bacteria was higher than that in patients with negative bacteria (P<0.05); There was no statistical difference in the adverse pregnancy outcomes in patients with different types of bacterial genus (P>0.05). Conclusion Pregnant genital tract flora are mainly ureaplasma urealyticum, candida and enterobacter, and the incidence of adverse pregnancy outcomes in patients with positive bacteria is higher, but different types of bacterial genus has no correlation with adverse pregnancy outcomes.

目的 探讨宫腔积血对于中晚期妊娠结局的影响以及影响的因素。方法 结合477例中晚期宫腔积血孕妇的临床资料分析,根据妊娠结局分为正常妊娠结局组(NP)及不良妊娠结局组(AP)。结果 AP的平均孕周(23.22±6.87周)明显大于NP(16.11±4.76周),两组有明显差异性(P<0.001)。两组首次B超宫腔积血平均体积分别为8.01(2.22~28.67)(NP),13.05(3.54~26.34)mL(AP)(P=0.001),但相邻第二次测量结果两组相差不大(P=0.230)。AP组中胎盘下血肿的比率(53.4%)明显大于NP组(24.2%),而绒毛膜下血肿比率(44.0%)明显小于NP(73.8%),两组有明显差异性(P<0.001)。宫缩也是影响因素之一,在AP组可扪及宫缩的病例(88例55.3%)明显高于NP(38例11.9%),两组有明显差异性(P<0.001)。但在阴道流血率方面两组没有明显差异(P=0.407)。结论 妊娠中晚期宫腔积血可能会导致不良妊娠结局,而首次出现的孕周,急性大量宫腔出血、宫腔积血位置以及是否伴有宫缩都是影响妊娠结局的重要因素。

Objective To study the poor pregnancy outcomes of patients with intrauterine hematoma in the second and third trimesters, and discuss the risk factors. Methods We analyzed the clinical data of 477 patients who underwent routine examination in our hospital from January 2010 to June 2016 and classified them into normal pregnancy (NP) group and adverse pregnancy (AP) group according to their pregnancy outcomes. Results Gestational age at first detection of hematoma of AP group(23.22±6.87 weeks) was more than NP group (16.11±4.76 weeks)(P<0.001). The volumes of hematoma during the first detection were significantly different between the two groups (P=0.001).The average hematoma volume were 8.01(2.22-28.67)(NP),13.05(3.54-26.34)mL(AP)respectively. However, the hematoma volumes recorded in the second B-ultrasound examination were not significantly different between the two groups (P=0.230). In the AP group, the incidence of retroplacental hematoma (53.4%) was significantly higher than in the NP group (24.2%), while the incidence of subchorionic hematoma (44.0%) was significantly lower than in the NP group (73.8%)(P<0.001). The incidence of palpable contractions in the AP group (62.8%) was significantly higher than in the NP group (12.1%), P<0.001. However, the incidence of vaginal bleeding was similar (P=0.407). Conclusion Intrauterine hematoma in the second and third trimester may lead to adverse pregnancy outcomes. Risk factors for poor pregnancy outcomes are included gestational age at first diagnosis, acute and large intrauterine bleeding, location of hematoma and accompanying contraction.
