EFFECT IN ACROSOME REACTION AND FERTILIZATION ABILITY OF SPERM WITH ULTRAVIOLET IRRADIATION

紫外线辐射对精子顶体反应和受精能力的影响

The identification and study of the control factors that regulate gene expression at different stages are of great value to elucidate the mechanism of spermatogenesis and spermiogenesis. Such study can also provide foundation and cues to investigating the mechanism of infertility and immunological contraception.

作为体内高度分化的雄性生殖细胞，精子发生过程中经历了从形态到生化的复杂变化，在这一过程中有一系列的特定基因按严格的时空顺序转录和翻译，因此寻找和研究不同发育阶段的差异表达的基因，将有助于最终阐明精子发生的机理，并为控制生育和不育机理的探索提供新的线索。

Spermiogenesis is a crucial process for germ cell formation, which ensures the efficient transmission of the paternal genome by the spermatozoa to the ooctyte at fertilization.

它包括染色质的压缩、顶体和鞭毛的形成以及去除多余的细胞质，是精子发生的一个重要环节，确保了成熟精子具有正确的形态和完整的功能。

There is a significantly difference between the tubular widthes of obstructive and non-obstructive azoospermic patients. The large number of intratubular germ cells within those tubules with active spermatogenesis cause those tubules to be larger than tubules without sperm production.

而藉由测量细精小管，我们得知造精功能受损患者的细精小管管径明显地较具正常造精功能的细精小管细，原因为造精作用活跃的细精小管内生殖细胞较多，因而造成有精子生成的细精小管管径明显的较没有精子生成的细精小管粗。

Although the western medicine had great progress in treating this disease, and the artificial reproductive technolog has improved the chance of fertility due to azoospermatism and severe oligospermia, the natural pregnancy is expected by every couple.

虽然近十年来现代医学在男性不育症的治疗有了长足的进步，ART大大增加了无精子症和高度少精子症病人生育的可能性，但是自然的妊娠还是人人所期望的。

The invention provides the technology used for identifying the bull X and Y sperm separation purity with low cost and simple, rapid, and accurate operation, and provides reliable technical support for the popularization and the application of the subsequent sexing semen and the optimization of a sperm separation method.

本发明提供了一种成本低廉，操作简便、快速、准确的鉴定牛X、Y精子分离纯度的技术，为后续性控精液的推广应用及精子分离方法的优化提供一个可靠的技术支持。

The explanation usually advanced for this is that macho men will provide the sperm needed to make sexy sons, but the more feminised phenotype makes a better carer and provider—in other words an ideal husband.

对此解释通常是促进下述内容，有男子气概的男性将提供必须的精子来制造儿子，但更女性化的男性是更好的照顾者和精子提供者，换言之是一个理想的丈夫。

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。
