I had it while TTC1, not quite long enough to notice any good or bad difference. But, I can fairly remember, I couldnt take up the taste and it was one of the reasons to give up. Another one was the only one cycle I took Maca, I had an anovulatory cycle. I am not sure whether Maca was the culprit or not, but I couldnt continue with it afterwards.
Another site says to start slowly, as lot of Maca root can cause you a massive acne breakout and can wreck your cycle. What dose you are taking? I was taking 525 mg a day, which is not too high dose.
