Effects of a Herbal Sex Enhancer (Vigpower) and Zinc Supplementation on Sex Hormones, Hepatic and Renal Function in Male Albino Rats

Abstract

Aim: This study evaluated the effects of a herbal sex enhancer (Vigpower) and zinc supplementation on sex hormones, hepatic and renal function in male albino rats. Methodology: A total of 49 male Albino rats weighing between 150 to 180g were used for the study. Vigpower, Viagra and zinc were orally administered to the rats daily for 28 days. Testosterone and estradiol were quantitatively determined using a rat-specific sandwich-enzyme linked immunosorbent assay (ELISA) method. The liver enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined using the Reitman-Frankel method. Alkaline phosphatase (ALP) was determined using the Colorimetric endpoint method. Sodium (Na+), potassium (K+) and chloride (CL-) were determined using ion selective electrode (ISE) method. Urea was determined using Urease bertholet method. Creatinine was determined using Jaffe-Slot method and qualitative phytochemical analysis was done on Vigpower capsule using classical methods. Results: Phytochemical analysis revealed the presence of flavonoids, protodioscin, saponins and phenols in the herbal capsule Vigpower. Testosterone levels were significantly higher in all the treatment groups compared to the negative control, with group 7 (Vigpower + Viagra + zinc) having the highest value. Estradiol levels were significantly lower, whereas testosterone-estradiol (T/E) ratio was significantly higher in all the treatment groups compared to the negative control, except for group 4 (zinc) which showed no significant difference compared to the negative control. ALT levels in the treatment groups were not significantly different from the negative control, except for groups 6 (Viagra + zinc) and 7 (Vigpower + Viagra + Zinc), which had significantly higher levels. AST and ALP levels in the treatment groups were not significantly different from the negative control, except for group 7 (Vigpower + Viagra + Zinc), which was significantly higher than the negative control and all other treatment groups. There was no significant difference in sodium (Na+), chloride (Cl-) and urea levels in the treatment groups, compared to the negative control. Potassium (K+) and creatinine levels were significantly higher in group 7 (Vigpower + Viagra + zinc), compared to the negative control and all other treatment groups. Conclusion: Singular administration of Vigpower, Viagra and zinc increased testosterone levels of the male rats. Vigpower and Viagra had equipotent effects on the sex hormones and also increased the testosterone-estradiol ratio. Vigpower, Viagra and zinc administered singularly, had no impact on liver enzymes and renal function. However, the combination treatment of Vigpower, Viagra and zinc was hepatotoxic and elevated potassium and creatinine levels. Herbal sex enhancers and their combination with other medications could provoke the desired sexual effect, but may damage other organ systems and pose serious public health challenges.
