Metallic ion concentration during menstrual cycle in normally menstruating women.

Plasma concentration of metallic ions levels during menstrual cycle of twenty normally menstruating women were observed in four phases i.e. menses, follicular, ovulatory and luteal. The concentration of magnesium, zinc, selenium and manganese was highest during menses and lowest at ovulatory phase. There was rise in ionic levels of magnesium and selenium, while fall in zinc and manganese during luteal phase. Findings demonstrate changes in metallic ions (Magnesium, zinc, selenium and manganese) level in relation to hormonal status during menstrual cycle in women.
