For me and maybe others, estrogen (as a group of hormones) and estrogen-like compounds (phytoestrogens) cause me to have leg (primarily calf) cramps.  I know about taking calcium and other supplements to help with cramps, but these supplements do not seem to work for me.  Does anyone know why the estrogen/phytoestrogen compounds cause leg (or muscle) cramps?  Does it have to do with testosterone levels already in my system? Or maybe it is the action of estrogen/phytoestrogen compounds trying to reduce male muscle mass?
