In biology, terrestrial creature rarely achieve orgasm in synch contrary to amphibia or aquatics. However, the political mass movement turns human into coral, which could achieve synchronized orgasm in mass scale. The slogans shouted by the people are like the sperm and eggs ejaculated by the coral.

就生物学而言，陆生动物不能像水生及两栖类动物可以同步高潮，可是政治群众运动将人类转变成为可以集体同步高潮的珊瑚虫，群众喊出的口号就像珊瑚集体排出的精子及卵。

Objectives: The purpose of this study is to analyse the point mutation of DYS1 in azoospermic patient and to find the relationship between point mutation and azoospermia.

前列腺作为男性生殖系统最大的附属性腺，其分泌的前列腺液构成精液的1/10～1/3，有保护、增强精子活动及润滑尿道等作用。

After that , the comparison of the fertilizable competences of ICSI and IVF on cryopreservated oocytes was studied in this article , in order to establish an optimized method to improve the fertilizable competences of oocytes up to the level of embryos .

和胞浆内单精子注射两种方法对玻璃化冷冻卵母细胞的受精能力进行了比较研究，旨在建立能够进一步提高牛冷冻卵母细胞受精能力的改进方案，使卵母细胞冷冻技术上升到与胚胎冷冻同样成熟的水平。

Besides, the efficacious concentration of either morrhuic acid or sodium morrhuate was 0.1%, so they contained more docosahexaenoic acid and eicosapentaenoic acid and were ideal spermicides in vitro.

所以，含有较多廿二碳六稀酸、廿碳五烯酸的鱼肝油酸和它的钠称是较为理想的体外杀精子剂。

The cleavage rate of ovocyte IVF of MⅡovocyte frozen withOPS method and activation method was higher remarkably than fluid spearmethod(P＜0.01), the cleavage rate of 2-cell after electrical activation was higher than IVF.

本试验推荐猪体外成熟培养体系为连续培养液48h的NCSU-23+10％FBS，细胞浓度为100个／400μl，发育培养体系为NCSU-23+BSA；用CRY-3细胞激活仪电激活时(电融槽宽度为1mm)为150v／20μs／2次+600μMγ-BLI；以活力为0.1左右的冷冻精液进行IVF时，精子浓度为10~7，共孵时间为6h，并在成熟处理时只部分去除卵丘细胞；MⅡ卵母细胞冷冻时，方法为移液枪头法+离心法，冷冻后激活的2-细胞卵裂率比IVF高。

Results: 15 patients with chronic epididymitis, 13 with tuberculosis of epididymis, 15 with cyst of epididymis, 14 with spermatic granuloma, and other three patients with spindle cell type rhabdomyosarcoma, adenoid tumor, papilloadenocystoma were reported and good results ...

结果 ：附睾慢性炎症 15例、结核 13例、囊肿 15例、精子性肉芽肿 14例、梭形细胞型横纹肌肉瘤、腺样瘤及乳头状囊腺瘤各 1例，手术效果良好。结论：附睾的恶性肿瘤少见。附睾肿块的诊断以临床表现、体检和病理检查为主，手术仍是有效的治疗方法。

ICSI using PESA sperm doesn't increase the incidence of pregnanct complications and offspring's malformation,so it is a safe and effective method to treat azoospermia.

PESA结合ICSI方法并没有增加妊娠分娩并发症及胎儿畸形的发生率，因此是治疗男性无精子症的一种安全、有效的方法。

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。
