目的探讨处理前精液参数对宫腔内人工授精(IUI)结局的预测价值。方法根据处理前精子浓度分为15×109/L、(15~30)×109/L、30×109/L 3组,根据处理前精子活力分为30%、30%~50%、50%3组,根据处理前活动精子总数(total mobile sperm,TMS)分为10×106、10×106~20×106、20×106~50×106、50×1064组,根据处理前精子正常形态率分为4%、4%~10%、10%3组,分别比较各组间的周期妊娠率。结果 355个IUI周期共获得53例妊娠,总周期妊娠率14.9%,处理前精子浓度、精子活力与妊娠率无明显相关性,处理前TMS各组妊娠率依次为6.6%、19.0%、15.9%及17.6%,后面3组与第1组差异有统计学意义(P0.05),处理前精子正常形态率各组间妊娠率依次为4.6%、16.9%及19.0%,后两组明显高于第1组(P0.05)。结论处理前TMS和精子正常形态率对IUI妊娠率有一定的预测价值,当处理前TMS10×106或正常形态率4%时,难以获得满意的IUI妊娠率,故不建议IUI治疗。 相似文献

目的:分析影响宫腔内人工授精(IUI)临床妊娠率的相关因素。方法:回顾性分析611个周期IUI者的临床资料,探讨女方年龄、不孕年限、不孕类型、所行周期数、周期方案、子宫内膜厚度及形态、处理前精液参数等因素与IUI妊娠率的关系。结果:促排卵周期妊娠率显著高于自然周期(23.03%vs 11.03%,P0.01),第4周期以上的妊娠率较第1、2、3周期明显下降(2.04%vs 21.03%、18.13%、12.67%,P0.01),当女方年龄≥40岁、处理前前向运动精子总数(TPMSC)10×106、前向运动精子百分率20%、正常形态精子百分率2%时,IUI临床妊娠率明显下降(P均0.05)。Logistic回归分析提示周期方案、所行周期数、前向运动精子百分率显著影响IUI临床妊娠率(P0.05)。结论:周期方案、所行周期数、前向运动精子百分率、女方年龄、TPMSC以及精子形态是影响IUI临床妊娠率的重要因素,而不孕年限、不孕类型、子宫内膜厚度及形态对IUI成功率没有明显影响。 相似文献

Objective:To analyze the outcomes of artificial insemination by frozen-thawed donor's semen(AID)and its affecting factors.Methods:Retrospective analysis of the results of 412 AID cycles performed in 173 couples be-tween February 2002 and December 2003 was presented,to evaluate the influence of female age,methods of insemination,therapeutic regime,post-thaw semen motility and number of treatment cycles on the fecundity of women undergoing AID.Results.Overall pregnancy rate of 31.6%(130/412)and delivery rate of 27.2%(112/412)per cycle and cumulative pregnancy rate of 72.3%(125/173)were achieved,with abortion rate of 13.9%(18/130)and multiple pregnancy rate of 2.68%.In 125 pregnant women,inseminations were performed 1-5 cycles,and 89.2% pregnant women conceived within three treatment cycles with twice AID in each cycle.Some factors such as ovarian stimulation(OS),female age(under 38 years),methods of insemination and luteal phase support bear no significant relations to preg-nancy rate,but the motility of post-thaw semen was significantly related to pregnancy rate.A-mong 115 neonates with weight 2,750~5,000 g,one was found congenital ventricular septal de-fect.Conclusions:Insemination with frozen-thawed semen is safe and effective.In women less than 38 years with normal reproductive function,satisfactory pregnancy rate could be achieved when AID was performed twice per cycle before and after ovulation within 4 consecutive sponta-neous cycles. 相似文献

Seven out of 27 infertile women conceived by intrauterine insemination (IUI, 26%), one of them twice. Three other pregnancies occurred spontaneously after the discontinuation of treatment. A comparison of the data obtained from 65 treatment cycles revealed that the number of motile spermatozoa per ml of ejaculate and per ml of medium after swim-up preparation was higher in the ultimately fertile group as compared to the patients who failed to conceive. It is concluded that male subfertility affects the outcome of IUI unfavorably. 相似文献

Conception Rate According to Semen Characteristics in a Series of 15 364 Insemination Cycles: Results of a Multivariate Analysis 总被引:2,自引:0,他引:2
The study was undertaken on 1438 ejaculates from 342 donors. The sperm count, volume, prefreeze and postthaw motility were evaluated for each ejaculate and the morphology for the first ejaculate of each donor. The success rate was found to increase steadily with the sperm count, prefreeze and postthaw motility. For the volume and percentage of all abnormal forms, the success rates are stable up to 5,5 ml and 40% respectively and then decrease. Among all the abnormal forms considered, only the microcephalics and irregular heads were found to be linked to the success rate. As most of the studied characteristics are correlated, a multiple stepwise regression was completed in order to determine the proper role of each variable. The most predictive variable is the postthaw motility. The second variable is the percentage of microcephalics. The other variables bring no further information. In particular, at a given postthaw motility, the prefreeze motility and consequently, the loss in motility have no influence on the success rate. 相似文献

We report two males with multiple sclerosis who were infertile as a result of failure to ejaculate. Electroejaculation was successfully used to recover semen with motile sperm from both men, and the sperm was used for artificial insemination. One pregnancy was achieved by intrauterine insemination, and a healthy male baby was born. 相似文献

Split-Ejakulat-Insemination mit und ohne Zusatz von Kallikrein 48 Ehepaare mit primärer Ehesterilität und einem therapieresistenten männlichen Faktor (Oligoasthenozoospermie, Asthenozoospermie) wurden einer Inseminationstherapie mit und ohne Kallikreinzusatz bei Verwendung von Splitejakulaten unterzogen. Bei allen Männern war im in-vitro Stimulationstest eine Verbesserung der Spermatozoenmotilität durch Kallikrein möglich. 468 Inseminationen wurden bei 341 Ovulationszyklen unter Verwendung der Basaltemperatur und des Cervixindex durchgeführt. Zur spermatozoenreichen Fraktion des Splitejakulates wurde physiologische Kochsalzlösung oder physiologische Kochsalzlösung mit Pankreas-Kallikrein in einer Endkonzentration von 5 Einheiten/ml zugesetzt und alternierend für ein Jahr inseminiert. Das Konzeptionsoptimum lag um den 7. Inseminationszyklus. 11 Schwangerschaften wurden nach Splitejakulat-Insemination mit Kallikrein und 6 Schwangerschaften nach Splitejakulat-Insemination ohne Kallikreinzusatz beobachtet. Die Konzeptionsrate lag bei 35%, die Abortrate bei 18%. Die Geschlechtsverteilung ergab 8 gesunde Mädchen und 4 gesunde Jungen. Innerhalb der Gruppe mit Oligoasthenozoospermie betrug die Konzeptionsrate 28%, bei der Asthenozoospermiegruppe 43%. Bei letzterer wurde eine mehr als doppelt so große Zahl von Schwangerschaften nach Kallikreinzusatz erzielt. Der Kallikreinzusatz war besonders günstig bei Ejakulaten, die weniger als 30% progressiv bewegliche Samenzellen enthielten. Die Untersuchung zeigt, daß die Splitejakulat-Insemination günstige Ergebnisse aufweist. Weiterhin erscheint der Zusatz von Kallikrein zum Inseminationssperma besonders bei Patienten mit therapieresistenter Asthenozoospermie sinnvoll. 相似文献

The relatively low pregnancy rates (PR) after treatment of patients with oligoteratoasthenozoospermia (OTA) result in a search for different treatment modalities. The objective of this study was to assess the efficacy of transcervical intrafallopian insemination (IFI) with husband's semen in comparison to intrauterine insemination (IUI) in couples with OTA. A prospective, randomized study included 30 couples with OTA-related infertility (according to WHO criteria). The female patients underwent individually adjusted controlled ovarian stimulation by gonadotropins. Spermatozoa was prepared using the Percoll 70% technique and insemination was performed 36-40 h after human chorionic gonadotropin (HCG) administration. The Tomcat Catheter was used for IUI and the Jansen-Anderson Catheter for IFI to the fallopian tube leading to the ovary that contained more dominant follicles. The couples were divided according to sperm count, into group A (9 couples): < 10 mill ml-1 and group B (21 couples): > 10 mill ml-1. Within the groups the patients were randomly assigned for IUI or IFI treatment. Among group B couples, two pregnancies out of 15 IUI cycles (13.3% PR) and two pregnancies out of 18 IFI cycles (11.1% PR) were achieved. Group A patients completed 7 IUI and 9 IFI treatment cycles with no pregnancies observed. These data did not demonstrate a statistically significant advantage for either technique. 相似文献

Efficacy of intrauterine insemination (IUI) using washed spermatozoa for treatment of oligozoospermia was evaluated by a prospective randomized study in 50 couples, using LH-timed natural intercourse in the alternate menstrual cycles as a control. The quality of spermatozoa in terms of their concentration and motility before and after sperm washing was compared. Sperm motility increased significantly after sperm preparation but the number of sperm was reduced. Eight pregnancies occurred in 253 cycles of IUI with washed spermatozoa and clomiphene citrate-stimulated cycles (3.16% per cycle). Only one patient conceived in 242 LH-timed natural intercourse cycles (0.41% per cycle). Compared with LH-timed natural intercourse, IUI provided a significantly improved pregnancy rate. When the sperm count was <5times106 per ml, no pregnancy occurred with the IUI method. Therefore, IUI is of rather limited usefulness when the sperm quality is very poor. Few complications occurred after IUI, but included slight cervical contact bleeding and mild abdominal discomfort and/or cramps. In conclusion, IUI should be considered as a useful and relatively non-invasive therapeutic modality for treating infertility caused by moderate oligozoospermia (>5times106 /ml), when sexual intercourse fails. 相似文献
