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。

Taring out container weight and then weighing sever components sequentially.

是称集装箱定皮重然后得出各个部件的重量所必不可少的仪器。

Sheep were weighed and wool and skin samples were collected at different times.
