Have any of you used Maca Root? Primarily I am curious about possibile sperm quantity increase, enhanced quality as well as improved mobility.

My wife and I would like to try for another baby and although we have not had real problems in the past getting pregnant, we are both getting older. It has been roughly 2 - 2 1/2 years since we conceived our last son (my wife just got her cycle back). I am now 39 going on 40 and my wife is 37. With recent reports that sperm plays a larger role in older infertility issues and that sperm abnormalities increase with age than previously thought, I would like to try and improve quality and quantity of sperm if possible.

Allegedly Maca Root is capable of doing that. From what I have read, that "appears" to be the one benefit (sexually) that does not seem to be overly disputed. I have started taking Maca Root & Folic Acid in hopes of improving quality of sperm & quantity. I have not had my sperm tested so I do not actually know if I need to do anything, its more of a desire to "put forth my best product"

Have any of you or our partners had any positive or negative experience with this or anything else?
