| Popis: | Guijiajiao-Lujiaojiao (GL) is a combination of Traditional Chinese Medicine (TCM) that can be used to treat oligoasthenozoospermia (OAS). However, its mechanistic role in OAS needs to be better understood and necessitates more studies. This study was planned to investigate GL’s therapeutic effects and its mechanistic role in the tripterygium wilfordii polyglycoside (GTW)-induced OAS rat model. In total, 60 Sprague–Dawley (SD) rats at 8 weeks of age were assigned to six groups: blank (NC), model (GTW), GL low-dose (GL-L, 0.3 g/kg/day), GL medium-dose (GL-M, 0.6 g/kg/day), GL high-dose (GL-H, 1.2 g/kg/day), and GL high-dose + PI3K inhibitor LY294002 (GL-H 1.2 g/kg/day + LY 1.2 mg/kg/day) groups. The model was characterized after 8 weeks to examine sperm concentration and viability, serum hormone levels, testes histopathology, and specific protein markers. The treatment efficacy was evaluated by mRNA and protein expression levels, among other parameters. Compared with the GTW group, the viability and concentration of rat spermatozoa were significantly increased after GL intervention ( p < .01). Meanwhile, the serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and T hormones in rats in the GL-M and GL-H groups were significantly higher than those in the GTW group ( p < .05). Furthermore, GL enhanced the proliferation of spermatogenic cells by modulating the PI3K/AKT signaling pathway, increasing and decreasing the levels of Bcl-2 and Bax proteins, respectively. It is concluded that the mechanism by which GL effectively enhanced the spermatogenic function of the GTW-induced OAS model may be attributed to the PI3K/AKT signaling pathway activation and the elevation of serum LH, FSH, and T hormone levels. |
