In conclusion, epididymosomes are small membranous vesicles secreted in an apocrine manner in the intraluminal compartment of the epididymis and play a major role in the acquisition of new proteins by the maturing spermatozoa.

总之，epididymosomes是一种小的膜状小泡，以顶分泌的分泌方式存在于附睾管腔中，在精子成熟过程中获取新蛋白发挥着主要作用。

We estimated incidences of disomy and for 2 autosomes and 2 gonosomes in sperm samples from 2 normal fertile men.

结果成功地在2.5小时内标记了同一精子核内的多条染色体，最佳的染色体同时标记通量为3条，单色以上标记率达到99％。

For years, scientists have been finding that endocrine disrupters like BPA can impair the reproductive organs of rats and mice, reduce sperm counts in rats, and bring about changes in tissue that resemble early-stage breast cancer, among other effects.

多年以来，科学家们已经发，像BPA这类内分泌干扰素可以损害家鼠和野生老鼠的生殖器官，降低精子质量，引起某些组织的变异导致早期乳腺癌，甚至还有其他一些不利影响。

Male minnows became feminised: their spermproduction was delayed and they started producing eggs.

雄性黑头呆鱼变的雌性化了：它们的精子生产被延迟，而且开始产卵。

Male minnows became feminised: their sperm production wasdelayed and they started producing eggs.

雄性黑头呆鱼变的雌性化了：它们的精子生产被延迟，而且开始产卵。

Eggs are then removed from her ovaries, fertilised with sperm in a laboratory dish, and then put back inside the woman's body to develop into a foetus.

鸡蛋，然后从她的卵巢，受精与精子在实验室里菜，然后放回内，该名女子的尸体要发展成为一个胎儿。

The hormones in the contraceptive patch stop your ovaries from releasing an egg each month, which could then be fertilised by sperm.

该激素的避孕药具修补程序停止您的卵巢从释放一个鸡蛋每个月，便可由精子受精。

Also, the intensity of immuno-positive reactions to them enhance with the development of the gonads.

免疫组织化学法也显示卵原细胞、卵母细胞、精原细胞、精母细胞和精子细胞存在睾酮和17β-雌二醇的免疫阳性物质，而且睾酮和17β-雌二醇的免疫反应强度也是随着性腺发育成熟而增强。

AIM: To observe the effects of infrasound on sperm quality and explore some underlying mechanisms.

目的：观察次声作用对大鼠精子质量的影响，初步探讨次声对雄性生殖系统的作用机制。

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。
