Effects of aescin on testicular repairment in rats with experimentally induced varicocele

Abstract

This study was conducted to investigate the effects of aescin treatment in a rodent model treated with an experimentally induced varicocele. Experimental varicocele was induced by partial ligation of the left renal vein of rats. Aescin administration was performed daily for 4 weeks after the varicocele induction. Seven weeks later, a contrast-enhanced ultrasound was performed of the rats' testis to assess testicular blood flow. The animals were sacrificed, and H&E staining was then used to evaluate testicular pathological changes and polymorphonuclear leucocytes density. Cauda epididymal sperm counts and motility were evaluated. Blood was collected for the measurement of follicle-stimulating hormone, luteinising hormone and testosterone. Contrast-enhanced ultrasound showed that there were significant decreases in testicular blood flow in the aescin-treated groups compared with those in control varicocele group. Testicular oedema was detected in those rats treated with a varicocele but without aescin, while no oedema was found in the experimental group. H&E staining showed dysfunctional spermatogenesis in both cohorts; however, polymorphonuclear leucocytes density was significantly reduced in aescin-treated groups. There was an increase in sperm counts of the aescin-treated groups. Our study demonstrated that aescin could exert therapeutical effects on reversal of testicular lesions in varicocele rats.

“…In addition, they can enhance the success rates of surgical treatment [11]. Although several empirical therapies with herbal agents for treating VC-induced infertility have been reported, none of them have been proven to be superior to others [2,9,12].…”

Effectiveness of Silymarin, Sulforaphane, Lycopene, Green Tea, Tryptophan, Glutathione, and Escin on Human Health: A Narrative Review

“…After 4 weeks of daily administration of escin, the density of polymorphonuclear leukocytes, the number and motility of spermatozoa in the epididymis, and the concentrations of follicle-stimulating hormone, luteinizing hormone, and testosterone were evaluated. It was seen that, in a group of rats treated with escin, the testicular blood flow was significantly reduced, the density of polymorphonuclear leukocytes underwent a significant decrease and, conversely, the sperm count increased [111]. Findings in human subjects were also encouraging.…”
