    Human endometrial tissue has higher levels of copper, potassium, rubidium, antimony, and zinc compared to decidua. Cyclic variations in endometrial calcium, rubidium, and copper were significant.

    Area of Science:

    • Biochemistry
    • Gynecology
    • Trace Element Analysis

    Background:

    • Trace elements play crucial roles in human physiology.
    • Understanding elemental composition differences between endometrium and decidua is vital for reproductive health research.

    Purpose of the Study:

    • To quantify trace element concentrations in human endometrial and decidual tissues.
    • To investigate differences in elemental profiles between these tissues.
    • To explore cyclic variations of trace elements in the endometrium.

    Main Methods:

    • Neutron activation analysis was employed to detect 25 trace elements.
    • 31 human endometrial tissue specimens across menstrual cycle phases were analyzed.
    • 14 decidual tissue specimens (12th-18th week of pregnancy) were analyzed.

    Main Results:

    • Copper, potassium, rubidium, antimony, and zinc were significantly higher in endometrium than decidua.
    • Bromine, selenium, and sodium levels were significantly lower in endometrium.
    • Cyclic variations in endometrial calcium, rubidium, and copper were highly significant.

    Conclusions:

    • Significant differences exist in trace element profiles between human endometrium and decidua.
    • Endometrial trace element levels exhibit significant cyclic variations.
    • These findings contribute to understanding the biochemical dynamics of the human reproductive tract.
