Effect of Moringa oleifera Lam. Leaf Tea on Sexual Behavior and Reproductive Function in Male Rats

This Thai study investigated whether moringa leaf tea could improve reproductive function in male rats. Researchers gave moringa leaf tea to male Wistar rats for 28 days and then examined various aspects of their reproductive health. The study found that rats receiving moringa tea showed significant improvements in several measures of reproductive function. Specifically, the diameter of seminiferous tubules (structures in the testes where sperm are produced) increased, as did the height of the epithelium lining these tubules. The researchers also observed higher counts of type A spermatogonia, which are early-stage sperm cells, and improved overall spermatogenic efficiency - meaning the process of sperm production became more effective. Chemical analysis revealed that flavonoids in the moringa leaves were likely responsible for these beneficial effects, particularly through their influence on Sertoli cells (which support sperm development) and steroidogenesis (hormone production). The study suggests that compounds in moringa leaves may support male reproductive health, though this research was conducted only in laboratory animals.
