Effect of Rourea coccinea on ethanol-induced male infertility in Wistar albino rats.

Ethanol consumption is a risk factor of male infertility. The use of medicinal plants offers an alternative for the treatment of male infertility in developing countries. This study aimed to evaluate the Rourea coccinea effect on ethanol-induced male infertility in Wistar rats. Twenty-five (25) male Wistar rats were randomised into five groups of five rats and treated by oesophageal gavage over a 28-day period. Group 1 (negative control) received distilled water; Group 2 (positive control) received 30% ethanol at 7 mg/kg body weight; Group 3 (reference control) received 30% ethanol co-treated with the reference drug, clomiphene citrate; Groups 4 and 5 (test groups) received 30% ethanol co-treated with Rourea coccinea hydro-ethanolic extract at 200 and 400 mg/kg respectively. Testosterone hormone, sperm parameters and testicular histopathology were evaluated. Ethanol treatment induced a significant reduction (p < .05) in sperm count, motility, viability and a significant increase in sperm abnormalities because of the significant decrease (p < .05) in testosterone levels. These data correlate with the alterations observed in the seminiferous tubule on histopathological examination of the testes. However, co-treatment of ethanol with Rourea coccinea extract or the reference drug restored the ethanol-induced toxic effects on the reproductive organs, sperm profile and testosterone level.
