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.
