Hydro-Ethanol Extracts of Xylopia aethiopica Enhanced Serum Testosterone Levels in Male Adult Wistar Rats

Abstract

Objectives To investigate the effects of hydro-ethanolic extracts of leaves and fruit with or without seeds on male sex hormones. Material and Methods Hydro-ethanolic extracts of the leaves, fruits with seeds, and fruits without seeds were processed using the Soxhlet extraction technique. Wistar rats were administered 125, 250, and 500 mg/kg of the extracts by oral gavage for 30, 60, and 90 days while the control group received feeds and water ad libitum. After the treatment periods, rats were sacrificed by cervical dislocation, and blood was collected by cardiac puncture. Serum follicle-stimulating hormones (FSHs), luteinising hormone (LH), progesterone, prolactin, and testosterone levels were determined using an enzyme-linked immunosorbent assay technique. Data were compared using analysis of variance (ANOVA), and a p-value of 0.05 was considered significant. Results Serum testosterone, FSH, and LH levels in rats treated with 125, 250, and 500 mg/kg were significantly increased (p < 0.05) in a dose-dependent manner compared with controls. Conclusion The consumption of this commonly used food spice appears to have beneficial effects on the male sex hormones.
