Effect of moringa oleifera lam. Leaf tea on sexual behavior and reproductive function in male rats

Abstract

Moringa oleifera Lam. (M. oleifera) has been called the “miracle tree” due to its attributes for therapy in various diseases. However, M. oleifera studies on the male reproductive system have been limited. The aim of this study was a phytochemical screening and investigation of the effects of M. oleifera leaf tea on sexual behavior, reproductive function and antioxidant activities. Male rats were fed with M. oleifera leaf tea extract at doses of 0.55, 1.10 and 2.20 mg/kg or distilled water for 30 days. The result showed that M. oleifera leaf tea contained rich total phenols and flavonoids. The courtship behavior, seminiferous tubule diameter, epithelium height, epithelium area, type A spermatogonia, and spermatogonia efficiency were significantly increased in all treatment groups. The groups treated with 1.10 and 2.20 mg/kg increased the number of Sertoli cells. The total of spermatogenic cells increased in the group treated with 0.55 mg/kg. M. oleifera leaf tea scavenged DPPH radical, ABTS radical and H2 O2, and inhibited LPO and AGEs formation. Due to M. oleifera leaf tea containing rich total phenols, flavonoids, and antioxidants, it could enhance sexual function and the male reproductive system.
