男性相关因素对夫精宫腔内人工授精妊娠率的影响

目的:探讨在宫腔内人工授精(IUI)过程中男性相关因素对妊娠成功率的影响,为临床IUI治疗不育提供参考。方法:选取排除女方因素和双方因素所导致的219周期不育IUI的资料,统计分析其中男性相关因素(如年龄、学历、不育年限以及精子形态正常率、精液处理前后前向运动精子数等)与妊娠率的关系。结果:共行IUI治疗219周期,妊娠23例,周期妊娠率为10.5%。随着男方年龄增长,拥有正常精子形态的人群比例呈下降趋势,差异有统计学意义。40岁以上年龄组妊娠成功率低于其他组(P<0.05),高学历组妊娠成功率也较其他组低,但比较差异无统计学意义(P>0.05)。男方不育年限各分组中妊娠率比较差异无统计学意义(P>0.05)。精子形态率正常组的妊娠率稍高于异常组,IUI妊娠率随着精液处理前后的前向运动精子数的增加均有上升的趋势,但比较差异无统计学意义。结论:男方年龄对正常精子形态的影响有统计学意义,但是男方学历、不育年限、处理前后的前向精子总数以及精子形态学等对IUI成功率无明显影响。     

正常形态精子百分率对宫腔内人工授精妊娠率的影响

目的探讨正常形态精子百分率与处理后前向运动精子总数达标率的关系及其对宫腔内人工授精临床妊娠率的影响。方法行夫精宫腔内人工授精的426对不孕夫妇（563个周期）,依据正常形态精子百分率分为3组,正常形态精子百分率〈4％为A组,≥4％～15％为B组,〉15％为C组,比较各组精液处理后前向运动精子总数达标率及对宫腔内人工授精临床妊娠率。结果A组精液处理后前向运动精子总数达标率低于B、C组（P〈0．05）,B组低于c组（P〈0．05）;A组周期妊娠率（7．77％）明显低于B、C组（16．21％、18．05％）（P〈0．05）。结论正常形态精子百分率对精液处理后前向运动精子总数达标率有明显影响,二者共同影响宫腔内人工授精结局;正常形态精子百分率≥4％可获较高临床妊娠率。     

影响夫精宫腔内人工授精妊娠率的因素分析

夫精人工授精是丈夫精液经过优选处理后置入妻子生殖道内以达到妊娠的一种方法,目前多采用将精子置入宫腔内,即夫精宫腔内人工授精方法(IUI).IUI简单易行,费用低,是当前最广泛应用的辅助生殖技术之一,但其周期临床妊娠率较低,仅10%～20%.本文旨在通过分析影响妊娠率的因素,探讨如何提高这项技术的妊娠率.     

精子DNA损伤与夫精宫腔内人工授精妊娠率的关系

[目的]探讨精子DNA损伤对夫精宫腔内人工授精(IUI)妊娠率的影响.[方法]收集本中心202个夫精宫腔内人工授精周期的临床资料,根据精子DNA碎片指数(DFI)将202个周期分为三组:A组:DFI＞30%,B组:30%≥DFI＞20%,C组:DFI≤20%,比较三组妊娠率.[结果]DFI＞30%的为5周期,妊娠数为0,周期妊娠率为0;30%≥DFI＞20%的为62个周期,妊娠数为6,周期妊娠率为9.68%;20%≥DFI的为135个周期,妊娠数为23,周期妊娠率为17.04% ;B组、C组妊娠率显著高于A组,但C组妊娠率显著高于B组,其差异均有统计学意义(P＜0.05).妊娠组的DFI(14.01±11.28)%显著低于非妊娠组精液DFI为(18.25±13.17)%,其差异有统计学意义.[结论]精子DNA的完整性与IUI结局密切相关;DFI可作为预测IUI结局、评价男性不育的临床指标.     

精液参数对宫腔内人工授精妊娠率的影响

目的探讨处理后前向运动精子总数（PTMS）及精子正常形态对宫腔内人工授精（IUI）妊娠率的影响。方法收集接受了共417周期IUI治疗的216对不孕夫妇。按处理前精子形态,将其分为形态正常组（正常形态精子百分比：〉15%,n=45）、轻度畸形组（正常形态精子百分比：〉10%-15%,n=103）、中度畸形组（正常形态精子百分比：〉5%-10%,n=186）和重度畸形组（正常形态精子百分比：≤5%,n=83）。根据PTMS将其分为5组,第Ⅰ组：PTMS〈2×106,第Ⅱ组：2×106≤PTMS〈5×106,第Ⅲ组：5×106≤PTMS〈10×106,第Ⅳ组：10×106≤PTMS〈20×106,第Ⅴ组：PTMS≥20×106。比较各组妊娠率。结果 216对不孕夫妇临床妊娠73例,周期临床妊娠率17.50%。第Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ组患者的临床妊娠率分别为3.3%、15.8%、24.1%、15.0%和21.4%。形态正常组、轻度畸形组、中度畸形组和重度畸形组患者的临床妊娠率分别为20.0%、20.4%、19.4%和8.4%。结论当PTMS〈5×106或正常形态精子百分比低于5%时,IUI妊娠率显著下降。

夫精宫腔内人工授精妊娠失败的影响因素分析

目的：探讨夫精宫腔内人工授精妊娠失败的影响因素,以期为提高夫精宫腔内人工授精妊娠率提供参考。方法：选择2018年2月~2019年8月就诊的500例夫精宫腔内人工授精患者为研究对象,随访至夫精宫腔内人工授精后5周,记录患者妊娠结局,并统计患者体质量指数、年龄、不孕类型、不孕时间、授精时机、治疗方式等信息,分析夫精宫腔内人工受精后妊娠失败的影响因素。结果：500例患者中行夫精宫腔内人工授精后妊娠成功70例,妊娠成功率为14.00%。单因素分析结果显示,夫精宫腔内人工授精妊娠失败不受体质量指数的影响,差异无统计学意义（P＞0.05）;可能受年龄、不孕类型、不孕时间、授精时机及治疗方式的影响,差异有统计学意义（P＜0.05）。多因素Logistic回归分析结果显示,年龄大、原发性不孕、不孕时间长、排卵前与排卵后单次授精、自然周期治疗均为影响夫精宫腔内人工授精后妊娠失败的影响因素（OR＞1,P＜0.05）。结论：年龄大、原发性不孕、不孕时间长、排卵前与排卵后单次授精、自然周期治疗均为夫精宫腔内人工授精妊娠失败的影响因素,临床可据此进行合理干预以提高夫精宫腔内人工授精妊娠成功率。     

宫腔内人工授精治疗免疫性不孕的效果

目的：分析评估夫精宫腔内人工授精（IUI）治疗抗精子抗体（AsAb）阳性的免疫性不孕患者的效果，指导临床医师为抗精子抗体（AsAb）阳性的免疫性不孕患者选择合适的助孕治疗方法。方法：对25对AsAb阳性的不孕夫妇进行的42个IUI治疗周期，与20对因女方排卵障碍的不孕夫妇进行的35个IUI治疗周期进行对比，分析IUI对抗精子抗体（AsAb）阳性的免疫性不孕患者的治疗结果。结果：AsAb阳性组的周期妊娠率为11．9％，排卵障碍组的周期妊娠率为31．4％，差异有统计学意义（P〈0.05）。结论：IUI治疗对抗精子抗体（AsAb）阳性的免疫性不孕患者效果欠佳，对此类不孕夫妇常需采用进一步的助孕技术。     

宫腔内人工授精治疗不孕症60例疗效分析

目的讨论官腔内人工授精（IUI）的临床妊娠率及其影响因素。方法用阴道B超监测卵泡发育及子宫内膜厚度情况,结合尿黄体生成激素（LH）峰判断排卵时间,用洗涤上游法处理精液,对我院2001年6月～2005年4月60例不孕症患者实施IUI。结果官腔内人工授精的妊娠率为21．67％。女性年龄越轻,IUI妊娠率越高。卵泡直径的大小与子宫内膜的厚度对官腔内人工授精的妊娠率有明显影响。结论女方年龄、子宫内膜的厚度和授精时机、促排卵方案等是影响官腔内人工授精妊娠率的主要因素。     

Predictors of pregnancy after intrauterine insemination in women with polycystic ovary syndrome

ObjectiveTo evaluate the effects of body mass index (BMI) in patients with polycystic ovary syndrome (PCOS) undergoing controlled ovarian stimulation (COS) with intrauterine insemination (IUI).MethodsThis retrospective study evaluated couples with PCOS undergoing COS and IUI. The relationship between cumulative IUI pregnancy outcomes and BMI, treatment cycles, treatment schemes, number of dominant follicles, endometrial thickness, infertility duration and type of infertility was analysed.ResultsThe study evaluated 831 IUI cycles in 451 couples with PCOS. Compared with normoweight women, overweight and obese women required more human menopausal gonadotropin (hMG) doses and more days of COS. Gestational diabetes mellitus occurred more frequently in the obese group than in the other BMI groups. The clinical pregnancy and live birth rates in the hMG, clomiphene citrate (CC) + hMG and letrozole (LE) + hMG groups were significantly higher than those in the CC and LE groups. The clinical pregnancy rate was higher in the secondary infertility group compared with the primary infertility group.ConclusionObese women might require more hMG doses and more days of COS to overcome the effects of weight. As BMI increases, the incidence of gestational diabetes might also increase. The number of cycles and type of infertility may have a predictive value for pregnancy outcomes.     

精子DNA损伤与精子形态、顶体完整率的关系研究

目的 探讨精子DNA损伤与精子形态和顶体完整率的关系.方法 对280例男性不育者进行精子DNA碎片指数(DFI)分析,并分析精子形态、顶体完整率.结果 严重畸形精子症组和顶体完整率异常组,精子DFI值显著增加;精子DFI≥40％组,精子正常形态率、顶体完整率均显著降低;精子DFI与正常形态率、顶体完整率呈显著负相关.结论 精子DNA损伤与精子形态、顶体完整率有密切关系,临床应结合精子DNA损伤程度和其他参数评价男性生育能力.     

供精人工授精中卵泡直径对妊娠率的影响

目的研究卵泡直径对供精人工授精(AID)妊娠率的影响。方法收集2016年1月至2018年12月在我生殖中心行AID助孕治疗的1073例不孕夫妇共2333个治疗周期的数据,根据术前卵泡直径将患者分为A组(<17 mm)、B组(17~<19 mm)、C组(19~<21 mm)、D组(≥21 mm),分析四组的妊娠情况。结果临床妊娠共636例,其中双胎共8例(1.26%),流产46例(7.23%),宫外孕10例(1.57%)。A、B、C、D组的临床周期妊娠率分别为27.48%、28.20%、26.98%、21.26%,B组高于其他三组。Logistic回归分析结果显示,女方年龄、卵泡直径对临床妊娠结果有一定的影响(P<0.05)。结论通过对不同卵泡直径AID妊娠结局的分析,发现卵泡直径15~17 mm者不宜放弃人工授精手术,但对于卵泡发育不良未妊娠者,再次AID可采用促排卵方案,以改善卵子质量,提高临床妊娠率。     

Relation between the number of sperms to be deposited and pregnancy rate in tubal insemination in rabbits

Pregnancy rate of tubal insemination with semen diluted to concentrations of ×10⁰ to ×10⁷ was studied in rabbits. The animals were laparotomized under general anesthesia, and 0.05 ml of diluted semen was injected with a glass capillary from the tubal fimbria into the oviduct. The semen was obtained from mature male rabbits by means of an artificial vagina and diluted to concentrations between ×10⁰ and ×10⁷. One hour after the insemination, ovulation was induced by administration of hCG. Six experimental groups were set up according to the semen concentrations. In the ×10⁰, ×10², ×10⁴, and ×10⁷ groups, newborn rabbits were obtained. The best pregnancy rate was obtained with the ×10² groups, in which 10⁵ level of sperms were deposited. The newborn rabbits were normal not only morphologically, functionally, but also in chromosomal examination. The results suggested that tubal insemination with a small number of sperms could be applied in sterility due to oligospermia in human.     

精子优选和精液冷冻对顶体完整率的影响

目的:探讨精子优选和精液冷冻对精子顶体完整率的影响。方法:16例精液样本采用Percoll和上游两种方法优选,13例精液标本采用快速和缓慢冷冻处理,采用巴氏染色法分析精子顶体完整率。结果:Percoll和上游两种方法优选后精子顶体完整率均明显高于优选前(P<0.05),两种优选方法间顶体完整率比较差异无显著性(P>0.05)。冷冻后与冷冻前顶体完整率比较差异无显著性(P>0.05),甘油-卵黄-枸橼酸钠(GYC)和甘油两种冷冻保护剂对顶体完整率的影响差异无显著性(P>0.05),速冻和缓慢冷冻对精子顶体完整率的影响差异亦无显著性(P>0.05)。结论:Percoll和上游法优选后精子顶体完整率较优选前明显改善。冷冻过程对顶体完整率无明显影响,速、缓冷冻方法和冷冻保护剂类型对顶体完整率亦无明显影响。     

促排卵方案对供精人工授精妊娠率的影响

目的研究不同促排卵方案对实施供精人工授精（AID）不孕妇女妊娠率的影响。方法对133对夫妇施行AID,促排卵方案为自然周期、克罗米芬（CC）、克罗米芬加促尿激素（CC＋HMG）、促尿激素（HMG）4种方法。结果56例成功,自然周期妊娠率30．77％（4／13）,CC妊娠率20．78％（16／77）,CC＋HMG妊娠率28．92％（24／83）,HMG妊娠率18．46％（12／65）（P〉0．05）。结论四种促排卵方案总妊娠率从高至低依次为CC、自然周期、CC＋HMG、HMG。     

Ovarian pregnancy rupture following ovulation induction and intrauterine insemination: A case report

BACKGROUNDOvarian pregnancy after assisted reproductive technology treatment has rarely been reported; ovarian pregnancy following intrauterine insemination (IUI) is even rarer, and only nine cases have previously been reported. CASE SUMMARYWe report a case of ovarian pregnancy rupture after ovulation induction and IUI. The patient presented with bilateral lower abdominal pain and was referred to the emergency department. Ultrasound examination revealed ovarian pregnancy and intraperitoneal bleeding. Laparoscopy revealed an ovarian pregnancy with hemoperitoneum, which was subsequently removed. Pelvic adhesions were detected intraoperatively, which were treated immediately. The patient spontaneously conceived an intrauterine pregnancy 3 mo later, which was ongoing at the time of writing this study. CONCLUSIONClose attention should be paid to any history of pelvic inflammatory disease before commencing IUI treatment,and patients with such a history should be closely followed up after IUI. Early measurement of serum β-human chorionic gonadotropin levels and ultrasonic examination are essential for timely diagnosis of ovarian pregnancy after ovulation induction and IUI to avoid more serious complications.
