この研究の注釈：
After 5 g of withania somnifera root powder daily, sperm quality increased in all three tested groups (three types of male infertility, fertile men were not tested); sperm concentration, overall volume, motility, and count all increased. All tested groups experienced an increase in anti-oxidant enzymes in the semen and a decrease in oxidative products, with the Normozoospermic group having greater levels of catalase than control.
