查询词典 IVF

The morphology and acrosome reaction of sperm may be two important parameters to evaluate the function of fertilization.

因此，精子形态分析和顶体反应二项参数，在自然周期和IVF周期中，对受精功能的评价有着不同的参考价值和意义；同时，在人类辅助生殖技术实施过程中可以作为选择不同辅助生殖技术的依据。

Sperm capacitation in vitro and acrosome reaction were premise and basic of IVF. So study on sperm capacitation and AR helps to the development of IVF.

精子体外获能和顶体反应是体外受精的前提和基础，因此对精子体外获能和顶体反应进行研究有助于体外受精技术的深入开展。

The result of frozen MⅡoocytes using three methods indcated that the self-restraintspear method was better than OPS, and the effection of frozen altogether with self-restraintspear method and centrifugal was the best; the frozen effection was not ideal using fluidspear for 8- cell ovocyte.

用三种冷冻方法(OPS法；自制移液枪头法；移液枪头法+离心法)对MⅡ卵母细胞冷冻的结果表明，自制移液枪头法优于OPS法，其中以移液枪头法+离心组的冷冻效果最好；用移液枪头法对体外发育到8-细胞期卵母细胞的冷冻效果不理想。MⅡ期卵母细胞用OPS法冷冻后卵母细胞IVF和电激活的卵裂率都显著高于移液枪头法(P＜0.01)，电激活后2-细胞卵裂率比IVF高。

Methods: Ninety infertility patients with the only cause of salpingemphraxis undergoing IVF-ET cycles were randomly divided into 2 groups, and received either urinary FSH or recombinant, in combination with long GnRH-a protocol to induce ovulation.

对单纯输卵管性因素行IVF-ET 90例患者，随机分为两组。

A new method for enucleating MⅡ nucleus in mouse and rat was induced; Living births were obtained from IVF of mouse oocytes reconstructed by transfer of metaphase Ⅱ chromosomes. For the interspecies nuclear transfer between mouse and rabbit, the reconstructed embryos could develop into blasocyst in vitro.

在不同品系小鼠卵母细胞核质交换移植中将电融合的重构卵进行IVF，经胚胎移植后顺利产仔；在异种核移植方面，小鼠核与兔卵母细胞的异种重构胚在体外培养条件下发育至囊胚阶段。

Materials and Methods: We got the follicle fluid when eggs were withdrawed during IVF cycle and then separated and cultured luteinized granulosa cells using serum free medium.

IVF周期穿刺卵泡取卵时所得卵泡液，进行颗粒细胞分离培养，在无血清培养体系中加入不同浓度VEGF，观察基础状态下或HCG作用下培养液中〓、P浓度的变化。

But because IVF is expensive and uncertain, most people want to create as many embryos as possible in one go. Extras are inevitable.

但是，由于IVF价格昂贵并具有不确定性，大多数人都希望一次能制造尽可能多的胚胎，因而就不可避免地有胚胎剩余下来。

This study retrospectively analysed the clinical data of 1134 cases after IVF-ET and 317 cases after cryopreservation and thrawing embryo transfer.

回顾性分析7年间施行IVF-ET(包括卵胞浆内单精子显微注射)1134个周期及冻融移植317个周期的资料，分析不孕原因及胚胎移植距宫底的深度与异位妊娠的关系。

The results show that: 1 supplementation of protein to maturation media improves cumulus expansion in vitro compared to the protein-free control, but cumulus expansion is not necessarily related to oocyte nuclear maturation in pigs, and cumulus expansion is not the criterae for determination of nuclear maturation of pig oocytes, but only the exclusion of the first polar body; 2 exposure of pig COCs to hormone supplements for 23-24 hours improved cumulus expansion but had no significant effect on nuclear maturation compared to that for 46-48 hours; 3 under our research conditions, supplementation of different proteins into different maturation media has different effects on porcine oocyte nuclear maturation, but has no significant effect on subsequent embryonic development after IVF; 4 the nuclear maturation rates of pig oocytes matured in mTCM+pFF and mNCSU+pFF are superior than that in mNCSU+FCS; 5 different maturation media have no effect on pig oocyte cumulus expansion and subsequent embryonic development after IVF.

结果显示：(1)在成熟液中添加蛋白质可以加强卵丘细胞的扩散，但猪卵母细胞的核成熟与其周围的卵丘细胞扩展没有必然的联系，卵丘细胞扩散或成放射状不宜作为猪卵母细胞核成熟的标准，只有排出第一极体才能作为猪卵母细胞核成熟的标志；(2)在猪COCs的46-48小时成熟培养的后23-24小时阶段去除成熟液中的激素不但可以保证卵母细胞的核成熟率，而且可加强卵丘细胞的扩散；(3)在现有实验条件下，在mTCM和mNCSU中添加10％pFF与在mNCSU中添加10％FCS相比可获得较高的猪卵母细胞核成熟率；(4)在不同的成熟液中添加不同的蛋白质对猪卵母细胞核成熟率的影响效果不一样，但对体外受精后的早期胚胎发育影响不明显；(5)成熟液种类对猪卵母细胞的卵丘细胞扩散和体外受精后的早期胚胎发育无显著影响。

Result: A total ratio of hybridization was 73.53%; in triploid zygotes after IVF, the ratios of triploid, diploid and monoploid were 92.31%, 3.85% and 3.85%, respectively.

结果：分析有杂交信号的3PN卵子68个，IVF后3PN的三倍体率为92.31%，二倍体率为3.85%，单倍体率为3.85%；共存在3种三倍体核型：XXX、XXY、XYY。

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。
