Massive apoptotic events are induced in the mutant gonads, leading to the abolishment of both spermatogenesis and oogenesis.

The ovine testicular tissue survived and its volume increased significantly, but it failed to differentiate to reach spermatogenesis.

结果表明，添加CsA组与不添加组的移植试验结果无显著差异；移植入的羊睾丸组织块可在受体动物中存活，体积明显增大，但不能分化以实现精子发生。

Frequently the basal ovule, which is the last one to be fertilized would abort

异卵双生子是由两个精子与两个不同的卵受精而成长起来的。

Therefore, we need to further research the ovulation days of women and choose the good-quality sperm and ovum for combination.

所以，我们需要进一步研究在女性排卵时日期，选择优质的精子和优质卵子结合的问题。

To solve this problem, we carry out full-dimensional researches on factors related with the combination of good-quality sperm and ovum.

为了解决这个问题，我们对优质精子和卵子结合相关的要素，进行了全面的研究。

Experiments show that: alcohol can pituitrin hypothalamus and the physiological effects of follicle damage and hormone, luteinizing hormone secretion and release of the normal, but also affect sperm quality.

实验表明：酒精可使脑垂体后叶和下丘脑的生理功能受损而影响卵泡激素、黄体生成素的正常分泌和释放，还可影响精子质量。

The polar body extrusion process of induced maturation is similar to naturally fertilized eggs.

在卵母细胞成熟过程中有受精膜举起的现象，说明精子入卵不是受精膜举起的必要条件。

Now targeted disruption of the Jhdm2a gene in mice shows that the enzyme is involved in spermatogenesis and regulation of transition nuclear protein and protamine genes.

现在对小鼠Jhdm2a基因的定向破坏表明，这种酶涉及精子生成和转换核蛋白及鱼精蛋白基因的调控。

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。
