Comparative study on the effect of Eurycoma longifolia and Smilax myosotiflora on male rats fertility

Abstract

The effects of Eurycoma longifolia Jack and Smilax myosotiflora were studied on sperm quality include sperm count, motility, viability and histology of the testis and pregnancy rate after mating with fertile proved females, as well as litter size on Sprague-Dawley (S-D) adult male rats. After dosing them with distilled water group A, group B 150 mg/kg body weight of aqueous extract of E. longifolia roots, group C 150 mg/kg body weight aqueous extract of S. myosotiflora leaf and group D 150 mg/kg body weight of E. longifolia combined with 150 mg/kg S. myosotiflora body weight daily for 14 days of stage (a) and 28 days for stage (b) of treatments. Results exhibited no significant variation (P>0.05) of stage (a),while results showed that E. longifolia Jack increase (P<0.05) the sperm count, motility, viability and histology of the testis and gender (male) of the litter size respectively of stage (b). This study provides evidence that E. longifolia Jack is a potent stimulator of fertility in male rat. © 2014 AIP Publishing LLC.
