Relationship between processed total motile sperm count of husband or donor semen and pregnancy outcome following intrauterine insemination

We retrospectively analyzed 6,360 artificial insemination cycles of husband's semen through intrauterine insemination (AIH-IUI) or artificial insemination with donor semen through intrauterine insemination (AID-IUI) in patients with infertility between August, 1998 and August, 2010. The relationship between processed total motile sperm count (PTMS) and pregnancy outcome was determined. The study was divided into 6 groups according to PTMS. Group 1:?≤?2.0 million, Group 2: 2.1-4.0 million, Group 3: 4.1-6.0 million, Group 4: 6.1-8.0 million, Group 5: 8.1-10.0 million, and Group 6: >10.0 million. There was no statistically significant difference in age, duration of infertility, unilateral tubal patency, induced ovulation, and single IUI or double IUI between the 6 groups in both AIH-IUI and AID-IUI. The total clinical pregnancy rate of AIH-IUI was 10.81 % and AID-IUI was 27.52 %. Among the 6 groups, the clinical pregnancy rate was the lowest in Group 1 (P?相似文献   

男性因素对宫腔内人工授精临床妊娠率的影响

目的：探讨男性因素对宫腔内人工授精（IUI）临床妊娠率的影响。方法：回顾性分析239对不孕夫妇行472个IUI周期的资料,分析男方年龄（＜30岁,30~35岁,≥35岁）、精子正常形态百分率（正常精子形态≥15%,10%~15%,5%~10%,≤4%）及精液处理后前向运动精子总数（PTMS）[＜2×106,（2~15）×106,（5~10）×106,（10~20）×106,≥20×106]对IUI临床妊娠率的影响。结果：472个IUI周期共获得80例临床妊娠,周期妊娠率16.95%,累积妊娠率33.47%。男方年龄≥35岁IUI组临床妊娠率显著下降,仅为10.4%（14/134）;重度畸形精子症组周期临床妊娠率为8.4%（7/83）,低于其他各组,差异有统计学意义（P＜0.05）。结论：IUI治疗过程中要充分考虑男方年龄对治疗结果的影响,当精子正常形态百分率＜5%或PTMS＜2×106时,IUI临床妊娠率显著下降,建议行体外受精-胚胎移植/胞浆内单精子注射-胚胎移植治疗以改善妊娠结局。     

人工授精及继用体外受精-胚胎移植助孕临床结局分析

目的:分析宫腔内人工授精(IUI)助孕及继用体外受精-胚胎移植(IVF-ET)助孕的临床结局。方法:回顾性分析本中心接受夫精人工授精(AIH)助孕1038例患者(年龄<40岁)的1657周期资料以及继用IVF-ET助孕的384例临床资料。结果:接受AIH患者临床妊娠率13.88%(230/1657),年龄、单侧或双侧输卵管通畅及助孕周期各组间妊娠率无差异(P>0.05),继发不孕妊娠率高于原发不孕(P<0.05),注入精子数量(10～20)×106组妊娠率最高(P<0.05)。继用IVF-ET助孕妊娠率52.34%(201/384),根据AIH助孕失败次数分组,各组内Gn用量、获卵数、移植胚胎数、优质胚胎数、受精率、临床妊娠率无差异(P>0.05)。结论:对于<40岁患者行AIH时,其不孕类型、注入精子数量是影响治疗妊娠的重要因素。根据患者年龄和不孕年限行AIH治疗不宜超过3周,年龄较大、不孕年限较长患者可提前继用IVF-ET助孕治疗。     

Intrauterine insemination with conjoint semen. How to increase the success rate?

BACKGROUND: Intrauterine insemination is usually proposed as the first line therapy for infertility related to cervical hostility, male factor, unexplained infertility or mild endometriosis. The overall succes rate of IUI is about 10-20% clinial pregnancy per cycle. The Aim of this study is to evaluate factors that increase the succes rate of IUI. METHODS: we restrospectively analysed 206 cycles of IUI with partner's semen in 138 infertile couples. The clinical and laboratory factors that may influence the pregnancy rates were analysed: women's age, etiology of infertility, duration of infertility, ovarian stimulation, day of hCG and sperm parametres. RESULTS: The per-cycle clinical pregnancy rate was of 14.56%. Optimal pregnancy rates were observed in less than 38 years old women (18.29% vs 9.52%, p<0.05). The succes rate was statistically depending of the number of IUI cycles until three (p<0.05), the day of hCG (p<0.05) and the sperm count after conventionally prepared semen (p<0.05). Sperm parameters was of no value in predecting the pregnancy rates, and neither seam's to be the total dose of administrated Gonadotrophin or the etiology of infertility, but it seams that, when a cervical factor or PCO were involved, the succes rate is higher. Besides, getting three or more than three follicles may increase the succes rate but expose to a warrying risk of multiple pregnancy. CONCLUSION: According to this study, the only statitically significant factors that are associated with successful IUI were, women partner's age (<38 ans), number of IUI cycles (during the first three IUI cycles), day of hCG (>J13) and sperm count after conventional semen preparation (>1.106/mL).     

影响宫腔内人工授精治疗结果的因素探讨

目的:探讨影响宫腔内人工授精(IUI)治疗结果的因素,以提高IUI治疗的临床效果。方法:对415个IUI治疗周期的240例患者的年龄、不孕年限、不孕原因、精液处理方法和处理后精子情况、IUI治疗周期数、一个周期内2次IUI以及促排卵方案与治疗结果的关系进行分析。结果:患者的年龄、处理后精子情况、IUI周期数和促排卵药物的使用与治疗结果有关;精液处理方法、一个周期内2次IUI和不同的促排卵方案对治疗结果没有影响。结论:患者的年龄、处理后精子情况、IUI周期数和促排卵药物的使用是影响IUI治疗结果的重要因素;一个周期内2次IUI和增加IUI的治疗周期数无法提高IUI治疗的临床妊娠率。     

夫精宫腔内人工授精手术时机和妊娠相关性分析

目的：探讨夫精宫腔内人工授精（IUI）时机及次数与妊娠率的关系。 方法：回顾性分析851对在广州医科大学附属第三医院行夫精IUI治疗的不孕夫妇（共1 751个周期）,根据手术时机及次数,分为排卵前1次IUI、排卵后1次IUI、排卵前2次IUI、排卵前后各1次IUI 4组,比较4组妊娠率的差异。 结果：排卵前、后行单次IUI组的妊娠率分别为11.21%和12.23%;排卵前行单次IUI后有排卵组妊娠率显著高于无排卵组（P＜0.05）。排卵前后各行1次IUI、排卵前行2次IUI妊娠率分别为16.21% 和15.65%;排卵前行2次IUI后有排卵组临床妊娠率（17.14%）高于无排卵组（0.00%）,差异有统计学意义（确切概率法 P=0.040）。有排卵周期中,排卵前1次、排卵后1次、排卵前2次、排卵前后各1次IUI的临床妊娠率分别为10.99%、12.23%、17.14%、16.21%,行2次IUI组的妊娠率虽然高于行1次IUI组,但差异无统计学意义（P＞0.05）。 结论：只要确定卵泡破裂,排卵前后行IUI、行1次或2次IUI妊娠率无差异;但IUI后卵泡无破裂,则妊娠率为0～2.85%,因此针对2个周期IUI出现未破裂卵泡黄素化综合征者建议转行体外受精。

目的：探讨SperMagic在自然周期夫精宫腔内人工授精中对精子活力及妊娠率的影响。方法：选择2012年3月—2012年6月进行自然周期夫精宫腔内人工授精的患者70例,随机分为2组：30例精子处理后添加SperMagic者为A组;40例精子处理后未添加SperMagic者为B组,比较2组精子活力和妊娠率差异。结果：A、B组年龄、不孕时间、体质量指数（BMI）以及精子处理前后密度、活力差异均无统计学意义（P＞0.05）;2组妊娠率差异亦无统计学意义（P＞0.05）,但A组有增高趋势。添加SperMagic后精子活力比精子处理后活力提高,差异有统计学意义（P＜0.05）。结论：在夫精宫腔内人工授精助孕技术中,精子处理后添加SperMagic可以明显改善精子的活力。     

影响宫腔内人工授精临床妊娠结局的相关因素

目的:通过对宫腔内人工授精(IUI)临床资料的回顾性分析,探讨男性因素与IUI妊娠结局的关系。方法:回顾性分析2010年1～12月在河南省人民医院生殖医学中心进行的329个IUI治疗周期的临床资料。按照IUI结局分为妊娠组、非妊娠组,比较各组患者在男方年龄、女方年龄、不孕病史、精子参数等方面的差异。分别按照男方年龄、女方年龄、不孕年限、精子参数等指标进行分组,比较各组患者妊娠率的差异。结果:妊娠组和非妊娠组的男女双方年龄、不孕年限等指标差异均无统计学意义(P>0.05);女方年龄>35岁组临床妊娠率低于≤35岁组(P<0.05),处理后前向运动精子数<2×106条组临床妊娠率低于处理后前向运动精子数≥2×106条组(P<0.05),其余各组临床妊娠率差异无统计学意义(P>0.05)。结论:在输卵管通畅的情况下,处理后前向运动精子数≥2×106条男性不育者应尽可能采用IUI进行治疗,处理后前向运动精子数<2×106条或女方年龄偏大时可考虑IVF或ICSI。     

Early experience with gamete intrafallopian transfer (GIFT) and direct intraperitoneal insemination (DIPI).

We present our early experience with gamete intrafallopian transfer (GIFT) and direct intraperitoneal insemination (DIPI) combined with intrauterine insemination (IUI), two recently described methods of assisting conception in patients with patent fallopian tubes. Sixty-nine patients (93 cycles) were entered into the study. Thirty-three patients (51 cycles) entered the DIPI/IUI programme and 36 patients (42 cycles) entered the GIFT programme. The mean age, duration and aetiology of infertility were similar in both groups. In the GIFT programme 12 pregnancies occurred, which is a 29% pregnancy rate per cycle and a 33% pregnancy rate per patient. In the DIPI/IUI programme only 3 pregnancies occurred, being a 6% pregnancy rate per cycle and a 9% pregnancy rate per patient. With the live birth rate of in vitro fertilization (IVF) being 12% per embryo transfer, we conclude that GIFT is more successful than either DIPI/IUI or IVF in patients with patent fallopian tubes. Further controlled studies are required to assess the future role of DIPI/IUI in clinical practice.

Contraindication of ART following a sperm FISH analysis,even though only 12% of the spermatozoa had enlarged heads

We report on a couple with a five-year history of idiopathic primary infertility. Two early miscarriages had followed intrauterine insemination (IUI). The man's fertility was then re-evaluated, in order to establish whether or not IUI was the best treatment option. Although the semen parameters were normal (sperm concentration: 89 million/ml; progressive motility: 40%; percentage of typical forms: 20%), a computer-assisted sperm morphology analysis with strict criteria found that 12% of the spermatozoa had enlarged heads. All of the latter had a normal form and none had multiple flagella. Using fluorescence in situ hybridization (FISH) analysis, we found that the proportion of aneuploid and diploid spermatozoa was 78% for the sample as a whole and 68% for normally-shaped spermatozoa with a normal-sized head. Although treatment options are well documented for men with macrocephalic sperm head syndrom, there is no consensus on individuals with a low but non-negligible proportion of spermatozoa with enlarged heads. Here, our FISH results contraindicated the use of assisted reproductive technology with the man's sperm. The couple decided to resort to donor sperm.     

COMPARISON OF TIMING OF IUI IN OVARIAN STIMULATED CYCLES

This study was conducted to compare pregnancy rates following two different timings of intrauterine insemination (IUI) in ovarian stimulated cycles. This retrospective study included 135 couples undergoing treatment for infertility. IUI was performed at either 24 hr or 36 hr after hCG injection. Pregnancy rates did not differ between the two groups or in subgroups receiving different methods of ovarian stimulation. Pregnancy rates were similar when IUI was performed at either 24 or 36 hr after hCG injection in ovarian stimulated cycles.
