精子的

Ananisogamy The sexual fusion of nonidentical gametes. Anisogamy grades from situations in which the gametes differ only in size to the extreme of oogamy, in which one gamete is a large nonmotile ovum and the other a small motile sperm.

异配生殖：不相同的两个配子的结合叫做异配生殖，通常是一个大而运动能力迟缓的卵和一个小而运动能力强的精子结合。

The key of immunological contraception is to discover a sperm antigen, which is tissue-specific and has the intense antigenicity.

应用疫苗进行避孕的一个最关键的问题是能发现一个精子特异的，且具有强免疫原性的抗原。

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。

Moreover, the quality, quantity and shape of the sperms also reduced with each level of increased phone usage.

此外，质量，数量和形状的精子也减少了每个级别的增加手机的使用。

They contain a spermicide a chemical that damages or kills the sperm.

他们包含一个杀精的化学物的损害或死亡的精子。

Therefore there is a need to develop a method by which large and purified populations of spermatids can be isolated, not only for the immediate requirement but also for cryoproservation for subsequent treatment cycles.

因此，有必要建立一种比较简单的、可获取大量纯化精子细胞的方法，不但可满足立即使用所需，也可进行冷冻保存用于以后的治疗周期。

Reverse transcriptase-PCR and immunohistochemical analyses show that mGC-G is predominantly expressed from round spermatids to spermatozoa in mouse testis at both mRNA and protein levels.

由RT-PCR与免疫组织染色证实mGC-G的mRNA与蛋白主要表现在睪丸中的精细胞与精子；mGC-G也表现於卵巢中的滤泡细胞与卵。

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。

Choose sitting on the couch, watching mind-numbing,spirit-crushing game shows, stuffing junk food into your mouth.

选择在沙发上看无聊透顶的节目，往口里塞垃圾食物。选择腐朽，由你精子造出取代你的自私小鬼，可以说是最无耻的事了。

Hamm and Leeuwenhoek were the first scientists to observe human sperm cells using an improved microscope in 1677 (more than 1000 years after Muhammad ).

公元1677年，两位科学家翰姆和列恩福克首先使用改进后的显微镜观察人类的精子细胞(在穆罕默德年代的1000多年之后)。

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.
