Comparison of sibling oocyte outcomes after intracytoplasmic sperm injection and in vitro fertilization in severe teratozoospermic patients in the first cycle

To follow up the outcome of sibling oocytes subjected to both conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in the first cycles of severe teratozoospermic patients with normal sperm morphology (NSM)or=6 cell embryos on day 3 and blastocyst formation on days 5 and 6, did not differ significantly between the two groups. There was a trend towards a high pregnancy rate cycle in mixed ICSI/IVF embryo transfer (ET) (49.1%). In conclusion, this study showed that in couples with only severe teratozoospermia, there was a benefit in subjecting sibling oocytes to both IVF and ICSI in the first cycle because 24 (28.2%) cycles of total fertilization failure were avoided. Furthermore, despite initially significant higher fertilization rates in ICSI than IVF oocytes, subsequent rates of development from >or=6 cells up to blastocyst stage were the same suggesting that ICSI should be used with caution, as after day 3, ICSI-derived embryo development was compromised compared with IVF.     

常规IVF完全/部分受精失败后行早期补救ICSI的应用

目的探讨常规短时受精联合早期补救卵胞浆内单精子注射(R-ICSI)在常规体外受精(IVF)失败和低受精率周期中的临床应用效果。方法回顾性分析2012年1月至2017年12月在河北省生殖医学中心接受IVF/ICSI-ET助孕治疗的2811个周期的临床资料,根据受精方式不同分为3组:R-ICSI组(210个周期):实施早期R-ICSI;IVF组(2062个周期):行常规IVF助孕;ICSI组(539个周期):直接行ICSI助孕。比较3组患者的一般情况、实验室指标和妊娠结局。结果R-ICSI组的原发不育比例显著高于IVF组(P<0.05),但与ICSI组比较无显著性差异(P>0.05)。3组患者的平均获卵数、移植胚胎数及MⅡ率比较均无显著性差异(P>0.05);R-ICSI组患者的受精率显著高于IVF组和ICSI组(P<0.05);R-ICSI组患者的2PN率显著低于ICSI组(P<0.05),但与IVF组比较无显著性差异(P>0.05);R-ICSI组的多PN率显著高于ICSI组,但显著低于IVF组(P<0.05);R-ICSI组患者的优胚率、可利用胚胎率及临床妊娠率均显著低于IVF组和ICSI组(P<0.05);R-ICSI组患者的着床率显著低于IVF组(P<0.05),但与ICSI组比较无显著性差异(P>0.05)。结论常规IVF受精失败及低受精的患者行早期R-ICSI可有效克服受精障碍,提高受精率,获得较好的妊娠结局。     

ICSI对高龄非男性因素不孕患者生育结局的影响

目的回顾性分析高龄非男性因素不孕患者ICSI或IVF受精后的临床结局,探讨ICSI在这类患者中的应用。方法回顾性分析2016～2018年期间在重庆妇幼保健院因非男性因素不孕接受微刺激促排卵方案治疗的高龄女性患者(≥38岁)的临床资料,根据受精方式分为ICSI组(n=189,共334个周期)和IVF组(n=189,共325个周期)。比较两组之间周期取消率、2PN受精率、优胚率、流产率及活产率的差异。结果两组之间患者年龄和获卵数均无显著性差异(P>0.05);ICSI组MⅡ卵率(85.92%vs. 92.27%)显著低于IVF组,2PN受精率(77.87%vs. 71.77%)和卵裂率(98.53%vs. 96.27%)显著高于IVF组(P均<0.05);两组之间的周期取消率、优胚率、胚胎冷冻率、流产率及活产率均无显著性差异(P>0.05)。结论 ICSI不能改善高龄非男性因素不孕患者胚胎质量和临床结局,此类患者首次助孕应选择IVF授精方式,而前次无2PN胚胎取消周期史的患者ICSI虽不能规避再次取消周期的风险但可有效改善其妊娠结局。     

ICSI as an effective therapy for male factor with antisperm antibodies

This study was conducted to evaluate if in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) is an effective treatment for infertility complicated by the presence in the male partner of sperm autoantibodies. Over a 1-year study period comparisons of fertilization, pregnancy, and implantation rates were made in couples where the male partner was negative or weakly positive for sperm autoantibodies (<50%) (gr 1); autoantibodies were strongly positive (>80%) (gr 2); or autoantibodies were moderately positive (50-80%) (gr 3). Only patients having oocytes fertilized by ICSI were included. The fertilization, clinical pregnancy, implantation, and miscarriage rate for group 1 (n = 67) was 56, 43, 21, and 14%. Comparable values for group 2 (n = 20) were 55, 40, 23, and 25%, and for group 3 (n = 6) were 63, 33, 23, and 0%. IVF with ICSI demonstrates comparable fertilization, pregnancy, implantation, and miscarriage rates in female partners of males with and without sperm autoantibodies.

目的 :探讨对不明原因原发性不孕患者行宫腔内人工授精 (IUI)失败后治疗方法的合理选择。　方法 :将6 1例共 6 5个周期的此类患者分为A、B、C、D 4组 ,分别为IUI后体外受精 (IVF)组 37个周期、IUI后卵细胞胞质内单精子注射 (ICSI)组 19个周期、IUI后一半行IVF一半行ICSI组 4个周期、IUI及IVF失败后第 2次改行ICSI组5个周期 ,同时随机选取常规行IVF治疗共 35个周期为E组、常规行ICSI治疗共 2 4个周期为F组作为对照 ,分别比较其正常受精率、完全不受精率、优质胚胎率、妊娠率及种植率。　结果 :A组的正常受精率、完全不受精率 (分别为 5 5 .4 %、2 1.6 % )与E组 (分别为 72 .8%、0 % )相比 ,差异有显著性 (P <0 .0 5 ,P <0 .0 0 5 ) ;与B组 (分别为6 8.4 %、0 % )相比 ,差异有显著性 (P <0 .0 5 ,P <0 .0 1)。D组患者自身对照前 1次IVF及随后的ICSI治疗 ,其正常受精率分别为 12 .2 %、74 .2 % ,差异有显著性 (P <0 .0 0 5 )。　结论 :不明原因原发性不孕患者IUI失败后行IVF有约 2 0 %完全不受精的可能 ,作为充分知情后的选择 ,行ICSI治疗可以获得较高的受精率 ,使患者有供移植的胚胎 ,但ICSI不应为推荐性的选择。     

部分ICSI在体外受精胚胎移植中预防受精失败临床效果

目的探讨部分ICSI(half-ICSI)在IVF-ET中预防受精失败的临床价值。方法回顾性分析2010年3月至2013年3月在本院生殖中心行half-ICSI治疗的77例患者(77个周期)。在77个周期中,一半卵母细胞行常规IVF受精,一半卵母细胞行ICSI治疗。在行half-ICSI患者中,以行IVF的一半卵母细胞是否正常受精进行分组:受精失败组(A组,31例)和受精正常组(B组,46例),对比两组患者的女方年龄、不育年限、不育原因、获卵数、成熟卵比例、优质胚胎率、种植率及妊娠率和临床累积妊娠率,同时比较两组ICSI的正常受精率及异常受精率。结果77个周期中常规IVF的受精率低下占40.2%(31/77),其中完全受精失败占25.9%(20/77)。受精失败组的不育年限比正常受精组长,差异有统计学意义(P0.05)。两组的女方年龄、不育原因、获卵数、成熟卵比例、优质胚胎率、临床累积妊娠率相比较,差异均无统计学意义(P0.05)。常规IVF受精失败组的胚胎移植数多于受精正常组,差异有统计学差异(P0.05),但两组的种植率及妊娠率差异无统计学意义(P0.05)。两组中ICSI的正常受精率和异常受精率差异均无统计学意义(P0.05),但B组的可用胚胎数多于A组,两组差异有统计学意义(P0.05)。结论对于原发不育年限较长,且无明确不育原因的患者可选择行half-ICSI受精方式,其不仅能有效防止受精失败,还能获得较理想的妊娠结局,这是预防受精失败行之有效的方法之一。     

异常形态精子对植入前胚胎发育和妊娠结局的影响

目的探讨异常形态精子(畸形率≥98%)对植入前胚胎发育及妊娠结局的影响。方法采用回顾性队列研究,分析2017年1～12月在唐都医院妇产科生殖医学中心行ART助孕的2 419例患者临床资料,根据异常形态精子分为3组,即IVF对照组(畸形率≤96%,n=2 129)、IVF实验组(畸形率≥98%,n=90)和ICSI实验组(畸形率≥98%,n=200)。比较3组间植入前受精失败率(受精率<30%)、正常受精率、可用胚胎率等胚胎发育参数和着床率、临床妊娠率、流产率及活产率等妊娠结局的差异。结果 (1)胚胎发育结果:组间比较,IVF实验组受精失败率显著高于IVF对照组(P<0.05),ICSI实验组的受精失败率为0;ICSI实验组正常受精率显著高于IVF对照组和IVF实验组(P<0.05);IVF实验组可用胚胎率显著低于IVF对照组和ICSI实验组(P<0.05)。(2)妊娠结局:单因素分析结果显示,与IVF对照组、ICSI实验组相比,IVF实验组的着床率、临床妊娠率、流产发生率和活产率差异均有统计学意义(P<0.05);IVF对照组和ICSI实验组组间妊娠结局指...     

卵细胞胞质内单精子注射在前次常规体外受精失败病例中的应用

目的:探讨卵细胞胞质内单精子注射(ICSI)是否可以改善由于受精障碍导致不孕病例的妊娠结局。方法:回顾性分析2002年1月~2004年12月由于第1周期的常规体外受精(IVF)治疗中卵子完全不受精或受精率≤20%,而在随后的治疗周期中采取ICSI方法受精的20个病例(共22个周期,研究组)的ICSI治疗结局。对照组为同期因男方少弱精子进行第1次ICSI治疗的连续100个周期。结果:与前次IVF相比,经ICSI治疗后受精率从5.4%显著提高至76.9%(χ2=264.66,P<0.001),但研究组中低受精患者经ICSI治疗后的受精率67.9%,明显低于对照组的77.5%(χ2=5.18,P<0.05)和研究组中完全不受精患者的84.2%(χ2=8.97,P<0.05)。研究组中完全不受精患者的妊娠率和胚胎种植率分别为57.1%和40.5%,均高于对照组的35.0%和18.9%,但仅胚胎种植率的差异有显著性意义(χ2=8.80,P<0.01)。结论:ICSI可以有效地克服受精障碍,提高受精率,并且可明显改善妊娠结局。     

少弱精夫妇接受传统体外受精和卵浆内单精子注射治疗结果的比较

本文将１２６个周期的ＩＶＦ和ＩＣＳＩ按男性精情况和治疗方法分３组,男方精液正常夫妇接受ＩＶＦ治疗共５１个周期为第１组,男方少、弱精夫妇接受ＩＶＦ治疗共２２个周期为第２组,男方少、弱精夫妇接受ＩＣＳＩ治疗共３０个周期为第３组。分别比较第１组与第２组、第３组与第２组的受精率、卵裂率和怀孕率。结果第２组的受精率明显低于第１组和第３组（Ｐ〈０．０１）,而不受精率为３１．８％,明显高于其它两组（Ｐ〈０．０１     

体外受精后6h应对受精失败的补救措施探讨

目的比较分析体外受精(IVF)后6 h补救卵胞浆内单精子注射(ICSI)和half ICSI应对受精失败的优劣。方法16例IVF完全受精失败周期采卵当日选取4个卵母细胞行ICSI,其余卵行常规IVF(half ICSI组);39例IVF完全受精失败周期在常规IVF后6 h补救ICSI(6 h补救ICSI组),比较两组的实验室指标。结果6 h补救ICSI组的受精率和冷冻胚胎比率显著高于half ICSI组,(分别为P0.01、P0.05);两组的卵裂率和优质胚胎比率无显著差异,妊娠率、种植率和累积妊娠率也无显著差异。结论IVF后6 h补救ICSI可应用在所有IVF周期,ICSI指征明确;half ICSI只能应用于不明原因不孕患者。工作中经患者知情同意后,在优先选择IVF后6 h补救ICSI的前提下,结合应用half ICSI,可提高受精失败患者的临床结局。     

The motility of epididymal or testicular spermatozoa does not directly affect IVF/ICSI pregnancy outcomes

Our objective was to determine whether the presence of motility in surgically obtained sperm samples improves fertilization and pregnancy rates for patients undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). This was a retrospective study in a hospital-based infertility center. Sixty-seven couples with a diagnosis of azoospermia or severe oligozoospermia who had undergone a sperm retrieval procedure in conjunction with 100 IVF/ICSI cycles from 1995 to 2004 were evaluated. The impact of sperm motility on fertilization and clinical pregnancy rates was determined. The motile and nonmotile sperm groups differed in the number of mature oocytes retrieved (10.7 +/- 5.8 vs 13.4 +/- 6.0), but fertilization (56.7% vs 59.1%) and embryo cryopreservation rates (35.9% vs 39.3%) were statistically similar. Clinical pregnancy rates did not differ between the motile (38.5%) and nonmotile (31.2%) groups, nor did they differ between obstructive and nonobstructive patients (35.3% vs 26.7%). There was also no statistical difference in pregnancy rates between testicular and epididymal aspiration (35.3% vs 26.7%), although epididymal sperm were significantly more likely to be motile than testicular sperm (100% vs 39.3%, P < .0001). Epididymal aspiration is more likely to produce motile sperm than testicular sperm retrieval. The use of motile sperm from epididymal or testicular samples, however, does not appear to enhance fertilization or clinical pregnancy rates.     

PCOS与非PCOS卵巢高反应患者的助孕结局比较

目的比较PCOS与非PCOS卵巢高反应患者的助孕结局。方法回顾性分析我院2016年1月至2018年12月行IVF/ICSI-ET助孕的卵巢高反应患者的病历资料(共1 236个周期),根据是否合并PCOS分为PCOS组(309个周期)和非PCOS组(927个周期)。比较两组患者的一般资料、促排卵情况、实验室指标及妊娠结局。结果两组患者的一般资料比较均无显著性差异(P>0.05);PCOS组患者体重指数(BMI)、抗苗勒管激素(AMH)、基础LH(bLH)水平和基础窦卵泡数(AFC)均显著高于非PCOS组(P<0.05)。两组患者促排卵方案所占比例、Gn天数、Gn总量、HCG日E₂水平比较均无显著性差异(P>0.05);PCOS组获卵数显著多于非PCOS组(P<0.01)。两组行IVF的情况比较,PCOS组受精率显著高于非PCOS组,2PN受精率和优胚率则显著低于非PCOS组(P均<0.05),2PN卵裂率比较无显著性差异(P>0.05);两组行ICSI情况比较,受精率、2PN卵裂率两组间无显著性差异(P>0.05),PCOS...     

Intracytoplasmic sperm injection in cases with history of in vitro fertilization failure

Aim: To evaluate the effect of intracytoplasmic sperm injection (ICSI) in the management of cases with a history of conventional in vitro fertilization (IVF) failure. Methods: Two groups of patients, 19 with normal semen parameters and a history of IVF failure (metaphase Ⅱ oocytes: 0~30 %) and 28 with severe male factor infertility received ICSI technology during the same period. Ovarian stimulation was achieved by conventional procedure. Transvaginal ultrasound-guided oocyte collection was done 35~37 h after human chorionic gonadotrophin (hCG) injection. Only metaphase Ⅱ oocytes were selected for microinjection. Results: Fertilization was achieved with ICSI in all the patients. The fertilization rate (75.6 %±21.1 % vs. 73.9 %±19.2 %), cleavage rate (85.1 %±19.3 % vs. 82.7 %±22.1 %), clinical pregnancy rate per embryo transfer cycle (31.6 % vs. 28.6 %) and implantation rate per embryo (15.3 % vs. 14.4 %) did not differ significantly between the two groups. Conclusion: ICSI is a valuable method for     

IVF—ET中未受精卵母细胞行早期（5hrs）补救ICSI授精后胚胎发育潜能

在常规应用卵胞浆内单精子注射（ICSI）之前,常规体外受精（IVF）受精率低下很常见,大约有20％～35％的IVF患者会发生受精率很低（〈35％的卵子受精）甚至受精完全失败（所有卵子都不受精）。卫生部辅助生殖技术管理条例规定,在应用辅助生殖技术助孕的治疗中,对以女方输卵管堵塞、排卵障碍、子宫内膜异位症或不明原因等不孕因素为主的患者,     

低剂量阿司匹林在体外受精-胚胎移植/卵胞浆内单精子注射周期中的作用

目的探讨阿司匹林对体外受精-胚胎移植/卵胞浆内单精子注射(IVF/ICSI)周期结局的影响。方法在本生殖中心IVF/ICSI周期中行常规长方案降调治疗患者共1,264个周期,采用前瞻性随机法,分为服用阿司匹林(实验组)684周期,未服用阿司匹林(对照组)580周期。实验组于前一周期黄体高峰期用促性腺激素释放激动剂(GnRHa)时加服阿司匹林(75 mg/d),于移植后14 d查血人绒毛膜促性腺激素(hCG)升高即停药。比较两组子宫内膜厚度、超促排卵及妊娠结果。结果实验组子宫内膜厚度(11.26±2.39)mm高于对照组(9.94±2.28)mm(P<0.05),但无明显临床意义。前者临床妊娠率(41%)高于后者(37%),但无显著性差异。余各项指标两组间均无明显差异(P>0.05)。结论在超促排卵过程中,加服阿司匹林,对获卵数,胚胎质量等无显著影响。虽可增加子宫内膜厚度,但临床意义不大。     

促甲状腺激素水平对新鲜IVF/ICSI周期妊娠结局的影响

目的探讨控制性促排卵前血清促甲状腺激素(TSH)水平高于4.0 mU/L,对IVF/ICSI新鲜周期妊娠结局的影响。方法回顾性分析2017年6月1日至2018年12月31日在本院进行IVF/ICSI助孕的患者资料,共4 457个周期。根据血清TSH水平,分为TSH≤4.0 mU/L组(n=4 107)和TSH>4.0 mU/L组(n=350),比较两组患者的一般资料以及妊娠结局。同时又对TSH>4.0 mU/L组内的患者按照4.0 mU/L5.0 mU/L(n=70)再分组,进行助孕结局的比较。结果以4.0 mU/L为分割点的两组患者年龄、不孕年限、体重指数(BMI)、血清抗苗勒管激素(AMH)、基础FSH、基础E₂、游离三碘甲状腺原氨酸(FT3)、游离甲状腺素(FT4)水平均无显著性差异(P>0.05);两组间的促排卵结局及临床妊娠率、异位妊娠率、活产率均无显著性差异(P>0.05);TSH>4.0 mU/L组的流产率(15.12%)略高于TSH≤4.0 mU/L组(12...

目的:评价前一周期行体外受精(IVF)失败和受精率低后,改行卵细胞胞质内单精子注射(ICSI)的受精效果。方法:行ICSI治疗的113例患者136周期分为两组:因严重少弱精子症而行ICSI的106个周期(组1);因前次常规IVF受精失败或受精率低于20%而改行ICSI的30个周期(组2)。比较两组间卵母细胞的正常受精率、优质胚胎率和妊娠率的差异,并对第2组受精率的分布进行分析,以了解改行ICSI后受精效果的改善情况。结果:改行ICSI后,两组的正常受精率和优质胚胎率差异均无显著性(70.49%vs72.02%;38.28%vs38.81%)(P>0.05)。两组的临床妊娠率分别为40.57%和40.00%,差异也无显著性(P>0.05)。改行ICSI后,大部分周期(70.00%,21/30)的受精率都在50%以上,平均受精率为79.79%,受精效果得到明显改善。结论:IVF受精失败和受精率低可以通过行ICSI而获得较好结局。     

来曲唑联合卵泡期高孕激素促排卵对高龄患者IVF/ICSI妊娠结局的影响

目的探讨在高龄患者行IVF/ICSI过程中应用卵泡期高孕激素促排卵(PPOS)方案联合来曲唑(LE)对妊娠结局的影响。方法回顾性分析2016年6月至2018年9月在我院生殖中心行IVF/ICSI助孕治疗的318个周期的临床资料。根据是否在PPOS方案早卵泡期应用LE进行分组,PPOS早卵泡期应用LE者为A组(n=120)和不应用LE者为B组(n=198),比较两组患者的一般情况和妊娠结局。结果A组患者在诱发排卵日血清E 2水平显著低于B组[(1730.55±1570.02)pmol/L vs.(2910.56±2084.52)pmol/L,P<0.05],而促性腺激素(Gn)使用天数及Gn用量显著高于B组[分别为(8.91±3.62)d vs.(7.83±2.72)d;(2245±1079)U vs.(1934±842)U,P<0.05];两组患者间获卵数、成熟卵子数、可利用胚胎数和周期取消率比较差异均无统计学意义(P>0.05);A组受精率显著低于B组(58.82%vs.69.71%,P<0.05);冻融胚胎移植后两组患者的累积妊娠率(20.85%vs.27.73%)和累积分娩率(11.69%vs.16.71%)均无显著差异(P>0.05)。结论应用PPOS方案促排卵时联合应用LE并不影响高龄患者IVF/ICSI的妊娠结局;应用LE导致的诱发排卵日E 2降低并不影响获卵数及可利用胚胎数。     

Comparison of conventional in vitro fertilisation and intracytoplasmic sperm injection outcomes in patients with moderate oligoasthenozoospermia

The method of choice for assisted reproductive technology treatment in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) is usually based on the evaluation of male infertility factors. Decisions for couples with moderate oligoasthenozoospermia (OA) are often empirical because uniform treatment criteria are lacking. This study aimed to evaluate the effect of patients with moderate OA treated with conventional IVF and ICSI. A total of 199 couples with moderate OA undergoing their first IVF/ICSI cycle were included in the study. The patients were divided into two groups according to the type of insemination: conventional IVF group (n = 97) and ICSI group (n = 102). All patients were randomised to be inseminated either by conventional IVF or ICSI. The fertilisation rate, embryo quality, implantation rate and clinical pregnancy rate were examined. No differences in the fertilisation, implantation and pregnancy rates were observed between conventional IVF and ICSI groups (P > 0.05). However, the number of good‐quality embryos was significantly higher in the ICSI group than in the IVF group (P < 0.05). Couples with moderate OA did not influence on the overall clinical outcomes between IVF and ICSI treatments, and a negative influence by ICSI on blastocyst development was not confirmed.     

Males with subnormal hypo-osmotic swelling test scores have lower pregnancy rates than those with normal scores when ovulation induction and timed intercourse is used as a treatment for mild problems with sperm count, motility, or morphology

This study was designed to evaluate the effectiveness and clinical usefulness of the hypo-osmotic swelling (HOS) test in predicting successful conception in couples in which men with mild male-factor infertility criteria were undergoing a timed vaginal inter-course protocol. One hundred couples, in which mild male infertility was the only abnormality, were included in the study. Semen was analyzed according to standard World Health Organization (WHO) criteria and subjected to the HOS test. Patients were divided into 2 groups: group 1 (n=39) with normal HOS test and group 2 (n=61) with abnormal HOS test. All women underwent three consecutive cycles of follicular growth ultrasound monitoring and timed intercourse. Ten couples were exclude from the study. Ten clinical pregnancies were achieved in group 1 with a pregnancy rate per patient and per cycle of 28.5% and 9.5%, respectively. In group 2, 6 pregnancies were achieved, with a pregnancy rate per patient and per cycle of 10.9% and 3.6%, respectively. Both pregnancy rates per patients and per cycle was significantly higher (P <.05) in group 1 than in group 2. The HOS test may be considered an easy and reliable test in identifying among subfertile men those who have a greater possibility of causing pregnancy.
