ABSTRACT
ObjectiveWe aimed to investigate the efficacy and mechanism of Yishen Shengjing Prescription (YSP) in the treatment of oligoasthenospermia in rats. MethodThe oligoasthenospermia rat model was established by injection with cyclophosphamide (35 mg·kg-1·d-1) for 5 consecutive days. Rats were randomly assigned into control group (without treating with cyclophosphamide), model group, low- (YSP-L), medium- (YSP-M), and high- (YSP-H) dose (2.91, 5.83, and 11.66 g·kg-1, respectively) groups, Wuzi Yanzongwan (WYW, 1.03 g·kg-1) group, and L-carnitine (0.17 g·kg-1) group, with 8 rats in each group. After 28 days of drug intervention, the body weight, testicular weight, and testicular index of rats were recorded. The sperm quality in epididymis was detected by computer-assisted sperm analysis (CASA) system. Hematoxylin-eosin (HE) staining was employed for observation of testicular tissue morphology. The levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in testicular tissue were detected by colorimetry. The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T) in serum were determined by enzyme-linked immunosorbent assayELISA). TdT-mediated dUTP nick-end labeling (TUNEL) was employed to detect the apoptosis of testicular cells. The protein levels of B cell lymphoma-2(Bcl-2), Bax, and cleaved Caspase-3 in testicular tissue were detected by Western blot. ResultCompared with the control group, the model group showed decreased body weight, testicular weight and index, sperm concentration and motility (P<0.01) and increased testicular pathological score (P<0.01). Compared with the model group, the YSP-M, YSP-H, WYW, and L-carnitine groups showed increased body weight, testicular weight, testicular index, sperm concentration and motility and decreased testicular pathological score. After modeling, the SOD level decreased (P<0.01) while the MDA content increased (P<0.01) in the testicular tissue. YSP-H, WYW, and L-carnitine reversed the SOD and MDA level changes caused by modeling. Compared with the control group, the model group exhibited declined T level (P<0.01) and increased FSH and LH levels (P<0.01). Compared with the model group, YSP, WYW, and L-carnitine increased the T level (P<0.01) and decreased the LH level (P<0.05, P<0.01). The apoptosis rate of spermatogenic cells in the model group was higher than that in the control group (P<0.01), whereas YSP-M, WYW, and L-carnitine reversed such changes (P<0.01). The model group rats showed decreased expression of Bcl-2(P<0.05) and increased expression of Bax and cleaved Caspase-3 (P<0.05, P<0.01). Compared the model group, YSP-M, YSP-H, WYW, and L-carnitine up-regulated the Bcl-2 expression and down-regulated the cleaved Caspase-3 expression (P<0.05, P<0.01). ConclusionYSP improved the sperm quality of oligoasthenospermia model rats by regulating the antioxidant system and sex hormone levels and inhibiting the apoptosis of spermatogenic cells.
