But we could recognize the efferent ducts because the cilia of the ciliated cells became red using HE staining .The epithelial cell height became higher and higher with time passing by.

睾丸输出小管的扩张，上皮高度的下降变得扁平使它的管腔也变得圆滑，但是在HE染色下纤毛上皮细胞的长长的纤毛被染成红色倒成了辨别睾丸输出小管的标志。

To elucidate the relationship of GSE expression and gametogenesis, mRNA (0.5μg each) from mouse testis and ovary on different postnatal days were analyzed by RT-PCR with specific primers for GSE cDNA. The GSE mRNA in the testis of mouse was first detected at Day 14 postpartum, when cells at mid-pachytene are likely to appear.

为了阐明GSE表达与配子发生的关系，从0～49日龄小鼠睾丸和卵巢中提取mRNA（每样品0.5μg，将其与特定的GSE cDNA引物进行RT-PCR反应，分析的结果发现，GSE mRNA在出生后第14天的小鼠睾丸中首先被检测到，这一时间正是中粗线期精母细胞很可能出现的时期。

Males born with and treated for undescended testicles should be told about it when they reach puberty, and they should learn how to do a regular self-exam of their testicles in order to detect any lumps and thus possible early signs of testicluar cancer.

出身时带有隐睾症或因该症经过治疗的男孩当进入青春期时，应该被告知疾病真相，并且应该学会如何有规律地自我检查睾丸，以探测任何肿块以及由此所致的可能的早期睾丸癌的迹象。

Each male ratwas paired with 2 female rats in proestrus when administration terminated. Femalerats were examined the next morning for the presence of sperm in vaginal smears andunderwent a cesarean section on day 13 of gestation. Then the reproductive indiceswere calculated as follows: copulation index, pregnancy index, and fertility index,which can evaluate male fertility directly. The sperm motility and morphology wereevaluated by computer-assisted sperm analysis, moreover, the caudaepididymal sperm ultramicrostructure were analyzed by transmission electronmicroscope, which can evaluate the influence on sperm maturation bydutasteride ; sperm survival rate was assessed by SYBR-14 and propidium iodidefluorescent staining; serumal dihydrotestosterone and testosterone of ratswere detected by enzyme-labeled immunoassay, which can evaluate the effecton androgenic levels; the weights of testes and epididymides, were determined byprecise electronic balance; histological examination of above tissues were evaluatedby HE staining and TEM, which can evaluate treatment on histology of reproductiveorgans by dutasteride.

给药结束后雄鼠与处于动情前期的雌鼠按2：1合笼，计算雌鼠的交配指数、受孕指数和生育指数，直接评价雄鼠生育力；采用计算机辅助精子分析系统分析大鼠附睾精子活力和形态，在此基础上合并使用透射电镜技术对各组附睾尾部精子进行透射电镜分析，评价度他雄胺对大鼠精子成熟的影响；采用SYBR-14和propidium iodide双重荧光染色计算精子存活率；采用Elisa法测定大鼠睾酮(testosterone， T)和双氢睾酮(dihydrotestosterone， DHT)血清浓度，评价度他雄胺对雄鼠雄激素水平的影响；采用精密电子天平对各组睾丸、附睾、前列腺和精囊进行称重，评价度他雄胺对大鼠生殖器官重量的影响；采用HE染色法对各组睾丸和附睾进行组织学分析，同时采用透射电镜技术对附睾上皮细胞超微结构进行分析，评价度他雄胺对大鼠主要生殖器官组织学的影响。

In order to accurately identify the sites of action of oestrogens and androgens, we have proceeded to the immunohistochemistry localization of the oestrogen receptors and the androgen receptor in the reproductive system and adrenal of sheep through gestation to adult.
