The other, more complicated, treatment involves a technique called intravaginal seminal graded challenge. The procedure, which takes several hours, involves doctors placing increasing amounts of the partner's semen into the woman's vagina at 20-minute intervals.

另外一种方法更复杂一些，用一种叫做阴道内精子分级免疫学的技术，治疗程序需要花几个小时，期间医生每隔20分钟向妇女的阴道中放入伴侣的精子，使女性阴道内的精子数量不断增加。

There were more Ca〓 deposite granules in and around the condensing granules of nucleoplasm; 2 There were large amount of Ca〓 in the Golgi complex of spermatid in Golgi phase. The Ca〓 in the acrosomal vesicle were probably from the Golgi complex; 3 Ca〓 was probably concerned with adherence of the acrosomal vesicle to the nuclear membrane.

发现（1）。Ca〓与精子形成过程中染色质的致密化有关，圆形精子细胞局部致密化的染色质团块周围及其内部和长形精子处于的致密化过程的核内均具有较多的Ca〓；（2）。

Result: In the same conditions, all the small, medium and large extracts of M. officinalis （0.125, 0.25, 0.5 g·mL-1）improved SOD vitality of sperm suspension, reduced the content of MDA, intervened in the injury of sperm membrane by ROS to some extent and protected some function of sperm membrane.

结果：巴戟天水提物小、中、大剂量组（0.125，0.25，0.5 g·mL-1）在相同的条件下均可提高精子悬液SOD活力，降低MDA含量，对ROS所致精子膜的氧化损伤均具有不同程度的干预作用，对精子膜功能具有一定的保护作用。

Moreover, RIM-BP3 and Hook1 mutant mice share several common abnormalities, in particular with regard to the ectopic positioning of the manchette within the spermatid, a presumable cause for the sperm head deformities.

而且，RIM-BP3和Hook1的突变小鼠具有一些共同的表型，尤其是精子细胞中精子领的异位分布，这是造成精子头部异常的潜在原因之一。

The cloning and identification of these genes are of great value to elucidate the mechanism of spermatogenesis and spermiogenesis.

发现并研究精子发育不同阶段表达的基因及其调控因子，深入研究它们在精子发生中的作用，将有助于阐明精子发生的机理，为探索不育机理和寻找免疫避孕的新途径奠定理论基础。

The cloning and identification of these genes are of great value to elucidate the mechanism of spermatogenesis and spermiogenesis. Such study can also provide foundation and cues to investigate the mechanism of infertility and immunocontraception.

发现并研究精子发育不同阶段表达的基因及其调控因子，深入研究它们在精子发生中的作用，将有助于阐明精子发生的机理，为探索不育机理和寻找免疫避孕的新途径奠定理论基础。

"Conclusively, the present study shows that toremifene administration... results in significant improvements of all three main semen parameters -- namely sperm count, motility and morphology -- mediated by increased gonadotropin secretion and possibly a direct beneficial effect of toremifene on the testes," researcher Dr. Anargyros Kourtis told Reuters Health.

研究人员Anargyros Kourtis博士告诉路透社，目前的研究表明，使用托瑞米芬后，在促性腺激素分泌增加以及托瑞米芬对睾丸可能产生直接的有益作用的介导下，三个主要的精液参数，即精子计数、精子活力和精子形态都可以得到显著改善。

To determine the true rate of aneuploidy and to elucidate the mechanism of aneuploidy,the sperms were decondensed for FISH analysis. It was found that the disomic frequencies of chromosome X was 0.208%. A new decondensation method was developed by trypsin treatment. The basic morphology of sperm was maintained.

为了解非整倍体的真实发生率及其发生机制，本文以X染色体α卫星DNA探针进一步检测出正常精子中X染色体的二体型频率为0.208％，同时，建立了一种保持精子基本形态的胰酶去凝聚的方法，为目前国内尚未开展的精子遗传物质结构的分子细胞遗传学研究，提供了新的手段。

PurposeThe present study was designed to pursue the kinetic characteristics of acrosome reaction of sperm in the fallopian tube in vivo, to evaluate the effect of human oviductal epithelial cell on the AR capacity of sperm and the possible mechanisms through the application of coculture system with HOEC in vitro.

目的 通过检测与人输卵管上皮细胞共培养的人精子在不同时间的顶体反应率，探讨精子在输卵管内AR过程的特点，分析HOEC对精子AR的影响和可能机制。

Up to now, scientists have estimated that about 3500~5000 mRNAs were retained in human ejaculated spermatozoa, and indicated that they may play important roles in the process of chromosome recombination, gene imprinting and spermatogenesis.

越来越多的研究发现成熟精子中存在有大量而复杂的mRNA群体，到目前为止，科学家们估计人正常射出的精子当中有3500-5000多种RNA，并且认为它们可能在染色体重新组装、基因印迹及精子发生过程中起着重要的作用。

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。
