Mammalian Spermatogenesis is a unique cell differentiation process and can bedivided into three stages: mitosis, meiosis, and spermiogenesis.

哺乳动物的精子发生是一个复杂的细胞分化过程，可分为有丝分裂期、减数分裂期和精子形成期三个阶段。

The immunostianing of ghrelin was not observed in Leydig cells after the impairment. Conclusion The changes in the expression of ghrelin suggest that ghrelin may play an important role in the function regulation of testis and the process of spermatogenesis and spermiogenesis.

结论Ghrelin在小鼠正常及辐射损伤睾丸中的特异性表达和变化，提示其可能与睾丸精子发生、精子形成及辐射损伤修复有关，具有重要的睾丸生物学调节功能。

We think that centrin play an important role in meiosis during Urechis unicinctus sperm metamorphosis difference and we also think that centrin may be related to trochophore cilia and sperm tail formation,and reconstraction of centrosome after fertilization.

我们推测Centrin在单环刺螠精子发生过程中减数分裂或精子细胞变态分化过程中发挥作用；在单环刺螠早期胚胎发育中，Centrin可能与受精后中心体的重建及担轮幼虫的纤毛形成有关。

Presence of a genetic factor like azoospermia factor microdeletions may lead to irreversible spermatogenic arrest in these cases.

遗传因子如无精子因子微缺失的存在可能在这些病例中导致不可逆的精子发生阻滞。

Spermatogenesis is the process by which spermatogonial stem cells divide and differentiate to produce sperm.

精子发生是由精原细胞增殖分化形成精子的过程，这一复杂的过程受到多种蛋白质的调节。

We also have captured the primary spermatocytes and round spermatids from rat testis sections by the application of the Laser Capture Microdissection technique.

RSB-66基因就是从初级精母细胞消减圆形精子细胞得到的SSH文库中得来的，这个蛋白质可能在精子发生过程中起重要作用。

When a woman experiences an orgasm, we think the intensity of the muscular contractions she has during the big pressure changes going on in her body helps to pull or suck up the sperm into her cervix and from there into the uterus, explained Pacey.

我们认为，当女性获得高潮的时候，其体内压力巨大变化的过程中发生的肌肉剧烈收缩有助于把精子吸入子宫颈，进而使精子进入子宫，Pacey解释说。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
