卵子

Fertilization of the egg by a single sperm occurs in the ampullary portion of the fallopian tube about a day after ovulation.

数百万的精子则向上运行，在输卵管的壶腹部，精子和卵子结合，称为受精，整个受精过程大约需要24小时。

The main research achievements on oogenesis and embryogenesis in mammals are described in this review,including the resumption of meiotic division;activation of MⅡ oocyte;development of parthenogenetic,gynogenetic,androgenetic and reconstituted embryos;and the genetic and reproductive potentials of chromosomes within the first and the second polar body.

本研究将论述哺乳动物卵子发生和胚胎发生的最新研究进展，包括：减数分列的启动， MⅡ期卵母细胞的激活，孤雌胚、雌核胚、雄核胚和重组胚的发育以及第一与第二极体染色体的遗传和生殖潜力。

Dr.Schappert: The four stage life cycle of butterflies is very discreet.An egg is obviously not a chrysalid,which is very obviously not a butterfly.

沙佩特博士：蝴蝶生命周期的四个阶段分得十分清楚，卵子显然不是毛虫，毛虫亦不是蛹，蛹更不是蝴蝶。

Only if the system is built and works well, may women give out eggs dignifiedly, whatever by "donating" or the so-called "selling".

Results Vasobral improved the development of larval and a dult stages,enhanced the vitality and increased the quantity and quality of ovum.

结果 活血素能促进家蚕幼虫期生长发育，提高蛹期茧质量，延长雌蛾生命，并能产生更多卵子。

The effects of different treatments on electrofusion of pig 2 cell embryos were studied with Hubei white pigs as experimental animals.

哺乳动物配子和早期胚胎细胞融合技术在研究卵子和早期胚胎发育中的细胞质相互作用，制作4倍体胚胎，杂种细胞构建和胚胎细胞核移植等方面有重要意义。

The feminine oviduct endophragm has the hairy structure, downward directs the egg, simultaneously helps the sperm toward the upstream.

女性输卵管内壁有很多毛状结构，将卵子往下引，同时帮精子往上游。

Mammalian spermatozoa go through the process of epididymal maturation to develop their capacity for fertilization.

随着精子在附睾中的转运，它们与卵子质膜的融合能力逐渐增加。

This indicates that CaHIRA plays a definitive role in the development of ovary or oogenesis. In coloreded crucian carp, Cahira gene was expressed in the unfertilized eggs. However its expression decreased dramatically after fertilization. The expression increased again and kept stable from gastrulation till hatching.

成鱼组织中，Cahira在卵巢、脑、心、肝、脾、肾中均有表达，在卵巢和肝脏中表达较强，而在精巢和肌肉中不表达，表明它可能在卵巢发育和卵子发生过程中发挥一定作用。

The oogenesis and ovary structure during development were studied in Haliotis diversicolor supertexta.
