精子形成

Antherozoid The male gamete of algae, some gymnosperms, and the non-seed-bearing plants.

游动精子：藻类，某些裸子植物和没有种子形成的植物中的雄性配子。

Methods: Human mature oocytes were cryopreserved using cryoleaf. Resuscitated oocytes were administered by intracytoplasmic sperm injection, embryo transplantation or cultured to blastulation, observing the fertilization and developmental capacity of oocytes.

运用cryoleaf进行人类成熟卵母细胞玻璃化冷冻保存，复苏后行胞浆内单精子注射-胚胎移植或培养至囊胚形成，观察复苏后卵母细胞受精及发育能力。

Basal bodies are the structures developed from bicentriole, the branched blepharoplast and blepharoplast, respectively, depending on the specific group of ferns concerned.

鞭毛、基体和多层结构中的微管带形成了游动精子三个独特的微管列阵，由于微管蛋白的后修饰作用这些微管列阵十分稳定；centrin是运动器中的重要成分，但功能尚不清楚，可能和细胞骨架及运动器的构建有关。

In addition, spermiogenesis includes chromatin condensation, migration of the cytoplasm and mitochondria to the caudal pole of the nucleus, formation of a moderate axial nuclear fossa containing the proximal centriole and part of the distal centriole and presence of a short cytoplasmic canal separating mitochondria from the flagellum.

另外，精子发生过程中还包括染色质浓缩，细胞质和线粒体向细胞核的尾端迁移，在核的后端中轴位置上形成中等大小的核后凹，近端中心粒和远端中心粒的一部分嵌在核后凹之内，短的胞质内陷管将线粒体与鞭毛分隔开。

We detected the frozen-thawed sperm of 36 Simmental,23 Charolais and 12 Limousin,the results showed that the frozen-thawed sperm of these three breeds could penetrate the zona-free ova of hamster,and formed male pronucleuses.

对36头西门塔尔、23头夏洛来和12头利木赞牛冷冻精子的实验结果表明：三个品种的牛冻精均能穿入去透明带仓鼠卵，并形成发育良好的雄原核。

Our results indicate that the protective effect of spermatic granuloma formation on the testis exists.

提示输精管结扎后精子肉芽肿的形成，对睾丸有一定的保护作用。

After the nucleus of the sperm has united with the nucleus of the egg, the result of their union, the zygote, begins a process of internal division.

受精以后数小时内，也就是精子的细胞核与卵子的细胞核融合以后，所形成的这个受精卵开始内部的分裂过程。

The effects of fenvalerate, phoxim and their mixture at about doses of LD〓 separately on the larva with 4 instars of cotton bollworm in development, spermatogenesis, spermateliosis and male mesoblast gonad were studied with micro-application method.

以毛细管点滴法，分别研究了约LD50剂量的氰戊菊酯、辛硫磷及其混剂对棉铃虫4龄初期幼虫的生长发育、精子发生与形成以及雄性中胚层生殖腺的影响。

In the adult, or medusa stage of a jellyfish, they can reproduce sexually by releasing sperm and eggs into the water, forming a planula.

在海蜇成体或水母体阶段，它们通过将精子和卵于释放到水中形成浮浪幼体而进行有性繁殖。

Most sperm nuclei eventually developed into the male pronuclei, just like the normal sperms, except sperm nuclei in a few zygotes kept dense throughout the fertilization process. Dense chromosome body was seen at the nuclear area during the prophase of first mitosis, and in the middle of spindle at metaphase of first mitosis.

精子入卵后形成精核，大多能够逐渐解凝、液化并膨大，最终形成形态正常的雄性原核，但在第一次卵裂早期退化成浓缩的染色质小体，并在胞质分裂时随机地分配到其中一个子细胞里的分裂沟附近。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
