Objective To investigate the relationship between ovum fertilization rate and sperm morphology, acrosome reaction in IVF and to explore the influence of parameters of sperm on fertilization rate.

目的 研究体外受精(in vitro fertilization，IVF)中精子形态、顶体反应与卵子受精率之间的关系，分析精子各参数在IVF受精率方面的参考意义。

But the Christian right is not vocally opposed to reproductive technology. By contrast they fiercely oppose stem-cell research on the ground that it destroys embryos—even when the embryos used for research are IVF extras. IVF yields babies, which is generally something the "pro-family" right approved of.

不过，这个基督教右派组织并未直言不讳地对生殖技术表示反对，相反他们强烈反对进行干细胞研究，原因在于后者破坏了胚胎，就算是所破坏的胚胎是IVF产生的多余胚胎也同样如此，而这个"支持家庭"的右派组织却并不反对IVF，因为它是在创造生命。

Hydrosalpinx is detrimental to the outcome of IVF-ET and may cause the increase of abortion,appropriate procedure should be adopted to deal with the problem before the IVF-ET and may improve the outcome of IVF-ET and may decrease the abortion rate.Compared with the salpingectomy,the proximal tubal ligation with distal tubal salingostomy may be a better option in this situation and it may cause less interference to the ovarian function.

输卵管积水对IVF-ET有不良影响，增加了流产率及异位妊娠率，在IVF-ET前对输卵管积水进行适当的处理有助于提高临床妊娠率，降低流产率；与输卵管切除术相比，输卵管近端结扎伞端造口术对卵巢功能影响较小，不增加流产率及异位妊娠率。

The data were divided into four groups,A group included 57 cycles:a proximal tubal ligation with distal tubal salingostomy had been introduced to the patients before the IVF.B group included 55 cycles,a salpingectomy had been introduced to the patients before the IVF.C group included 52 cycles:no surgical procedure was adopted before IVF-ET.The control group was defined as D group and included 78 cycles of IVF-ET.

回顾性分析2007年3月至2009年3月在沈阳204医院生殖中心因输卵管性不孕接受IVF-ET 治疗共242周期的临床资料，根据IVF-ET前输卵管情况分4组，A组：57个周期，采用输卵管近端结扎伞端造口术；B组：55个周期，已行输卵管切除术；C组：52个周期，积水未行手术组；D组：78个周期，单纯输卵管阻塞，作为对照组。

After that, the comparison of the fertilizable competences of ICSI and IVF on cryopreservated oocytes was studied in this article, in order to establish an optimized method to improve the fertilizable competences of oocytes up to the level of embryos.1 Effects of the reducing injury methods on IVF of cryopreservated oocytesThe result of the three methods, choosing the right time oocytes, using minimum size sample vitrification and culturing after thawing, showed that these ways could partly maintained the fertilizable competences of cryopreservated bovine oocytes.

减轻损伤方案对冷冻卵母细胞IVF的影响使用选择合适时期的卵母细胞进行冷冻；采用最小样本量玻璃化冷冻方法进行冷冻；在解冻后先孵育再进行体外受精等三种方案能够部分维持或恢复冷冻牛卵母细胞IVF受精能力。

The lower pregnancy rate was found in Group C,the highest abortion rate and ectopic pregnancy rate were found in Group C was 21.15% and 7.69% repectively,and was statistially different from that in control group (P.05).Conclusion Hydrosalpinx is detrimental to the outcome of IVF-ET and may cause the increase of abortion,appropriate procedure should be adopted to deal with the problem before the IVF-ET and may improve the outcome of IVF-ET and may decrease the abortion rate.

输卵管积水对IVF-ET有不良影响，增加了流产率及异位妊娠率，在IVF-ET前对输卵管积水进行适当的处理有助于提高临床妊娠率，降低流产率；与输卵管切除术相比，输卵管近端结扎伞端造口术对卵巢功能影响较小，不增加流产率及异位妊娠率。

Methods The data of 242 cycles of IVF-ET which were accomplished in the Reproductive Medicine Center of 204 hospital during March 2007 and March 2009 with a history of hydrosalpinx were analyzed retrospectively.The data were divided into four groups,A group included 57 cycles:a proximal tubal ligation with distal tubal salingostomy had been introduced to the patients before the IVF.

The cleavage rate of ovocyte IVF of MⅡovocyte frozen withOPS method and activation method was higher remarkably than fluid spearmethod(P＜0.01), the cleavage rate of 2-cell after electrical activation was higher than IVF.

本试验推荐猪体外成熟培养体系为连续培养液48h的NCSU-23+10％FBS，细胞浓度为100个／400μl，发育培养体系为NCSU-23+BSA；用CRY-3细胞激活仪电激活时(电融槽宽度为1mm)为150v／20μs／2次+600μMγ-BLI；以活力为0.1左右的冷冻精液进行IVF时，精子浓度为10~7，共孵时间为6h，并在成熟处理时只部分去除卵丘细胞；MⅡ卵母细胞冷冻时，方法为移液枪头法+离心法，冷冻后激活的2-细胞卵裂率比IVF高。

Most IVF pregnancies are singletons but the rates of multiple gestations are much higher than those seen in spontaneous conceptions: approximately 30% of all pregnancies occurring via IVF are multiples, the majority being twins.

大多数IVF婴儿是独生子，但是与自然怀孕相比，IVF多胎怀孕的几率要高得多：全部IVF受孕婴儿中约有30%是多胞胎，绝大多数是双胞胎。

4H was the best time of bovine oocyte activationin the 6-DAMP, and the cleavage rates and blastula rates could reach 85.1% and 26.8%. 4. IVF-100 was used in vitro fertilization, because IVF-100 was not needed to prepare usually,store conveniently, and gain a higher cleavage rates. After the oocytes have matured for 20h, theywere digested by permease and treated with suctionpipe.

由于IVF-100无需经常配制、保存方便且可以获得较高的卵裂率，所以本实验采用IVF-100为受精液，卵母细胞成熟20小时后采用透酶+口吸管消化的方法处理，获得了较好的受精效果，卵裂率可达(76.8％)。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
