Comparison of the levels of copper, zinc and iron in cervical mucus and in blood serum of women of childbearing age.

The objective of this research study was a preliminary comparison of some chosen trace elements concentrations in cervical mucus and blood serum of women of childbearing age. The levels of iron (Fe), copper (Cu) and zinc (Zn) were determined in cervical mucus and serum of 10 patients. The obtained results do not point to any association between the levels of the examined trace elements in cervical mucus or any correlation between their contents in mucus and blood serum. As no correlation was found between the blood serum and cervical mucus, as far as trace elements are concerned, one might suggest that the uptake of trace elements by the mucus has an active form.
