Does Maca increase chances of twins?

Most of what I know about maca is that it increases libido and strengthens sperm. It can't hurt, but if it could increase chances for twins, there is no way that you can be prepared for multiples. I have twins and I found out at 14 weeks and we were shocked. When they were 1 year old, we still could not believe it. They are 4 now and I still find myself thinking "WOW! 2 at the same time!"
