Abstract EN
Background.
Diagnosing polycystic ovary syndrome (PCOS) is based on ovulatory dysfunction, ovarian ultrasound data, and androgen excess.
Total testosterone is frequently used to identify androgen excess, but testosterone is mainly bound to sex hormone-binding globulin (SHBG) and albumin.
Only 1-2% of nonprotein-bound testosterone (so-called free testosterone) is biologically active and responsible for androgen action.
Moreover, automated immunoassays which are frequently used for female testosterone measurements are inaccurate.
Objective.
To assess the clinical usefulness of liquid chromatography-tandem mass spectrometry measured testosterone and calculated free testosterone in subfertile women attending a fertility clinic with oligomenorrhea and suspected PCOS.
Methods.
Hormonal and metabolic parameters were evaluated, and ovarian ultrasound was performed.
Total testosterone was measured by liquid chromatography-tandem mass spectrometry.
Free testosterone was calculated from total testosterone and SHBG.
Results.
Sixty-six women were included in the study.
Total testosterone was associated with ovarian volume and antral follicle count but not with metabolic parameters.
However, SHBG and calculated free testosterone were associated with both ovarian ultrasound and metabolic parameters, such as BMI and insulin resistance.
Conclusions.
Assessing SHBG and free testosterone is important in evaluating androgen excess in subfertile women with ovulatory dysfunction and suspected PCOS, as it reflects both ovarian and metabolic disturbances.
