Hi mrsD,
Thank you for responding. Although I have run across information about the use of Maca for men there is also quite a bit of information about it's use for perimenopause/menopause. Maca appears to be useful for both men and women.
My gyn does not recommend using progesterone cream or a phytoestrogen at this time so I started researching alternatives to medication for mood swings that are becoming quite difficult. I already have an anxiety disorder that is treated with Klonopin but there are times I can take the full dose (1mg 3x a day) and not get any relief. This is all related to this very normal transition time of my life.
