Effect of Lepidium meyenii on in vitro fertilization via improvement in acrosome reaction and motility of mouse and human sperm

Reproductive Medicine and Biology, 2019
Purpose The direct effects of Lepidium meyenii (Maca) on sperm remain unclear. Herein, we examined the direct effect of Maca on in vitro fertilization. Methods We examined the fertilization rate in a mouse model and the rate of acrosome reaction in sperm
