Summary

Postmenopausal women show increased extraction of etiocholanolone (ET) compared to androsterone (AN). This urinary steroid profile shift, confirmed by the ET/AN ratio, highlights hormonal changes in postmenopause.

Area of Science:

Endocrinology
Analytical Chemistry
Reproductive Biology

Context:

Menopause is associated with significant hormonal shifts.
Urinary steroid profiling provides insights into endogenous hormone metabolism.
Capillary gas chromatography (GC) is a sensitive technique for steroid analysis.

Purpose:

To investigate urinary steroid profiles in postmenopausal women.
To compare the excretion levels of etiocholanolone (ET) and androsterone (AN).

Summary:

Urinary steroids were analyzed using capillary gas chromatography with OV-1 glass columns.
Results indicated a higher extraction of etiocholanolone (ET) in postmenopausal women compared to androsterone (AN).
The calculated ET/AN ratio corroborated these findings, suggesting a specific alteration in androgen metabolism postmenopause.
