Abstract

Purpose: To investigate the effect of total flavonoids of Cuscuta chinensis (TFCC) on oxidative stress injury in testis and epididymis, and serum levels of reproductive hormones in an oligoasthenospermia (OAS) mice model.

Methods: Thirty male Wistar mice were randomly assigned to three groups of 10 mice each: control group, OAS group and TFCC group. With the exception of control group, OAS was orally induced in the mice with ornidazole. The TFCC group received TFCC. Reactive oxygen species (ROS), malondialdehyde (MDA) and superoxide dismutase (SOD) were determined. Serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone were also measured.

Results: The levels of ROS and MDA in the testis and epididymis significantly increased in OAS group, when compared to control mice (p < 0.05). However, TFCC administration significantly reduced their levels in these tissues (p < 0.05). In contrast, SOD activity significantly decreased in the testis and epididymis of mice in OAS group, relative to control group, but increased significantly after TFCC exposure (p < 0.05). Serum FSH and LH were markedly elevated in OAS group, but treatment with TFCC significantly reduced the levels of these hormones (p < 0.05).

Conclusion: These results suggest that TFCC effectively improves sperm quality and reduces oxidative damage in testis and epididymis of mice with oligoasthenospermia via a mechanism involving the regulation of serum levels of reproductive hormones. Thus, TFCC may be useful in the treatment of oligoasthenospermia.
