Total testosterone to dihydrotestosterone ratio assessed by LC-MS/MS predicts a worse metabolic profile not only in PCOS patients
open access
Abstract
Objectives: Total testosterone/dihydrotestosterone ratio (TT/DHT) was found to determine metabolic risk in polycystic ovary syndrome (PCOS). The aim of this study was to analyze whether (TT/DHT) may be helpful in predicting metabolic risk not only in PCOS patients but also in healthy women.
Material and methods: Total testosterone (TT), dihydrotestosterone (DHT), androstendione and dehydroepiandrosterone sulphate (DHEA-S) were measured by LC-MS/MS in 36 women with PCOS and in 29 age-matched controls without clinical hyperandrogenism. In all participants, anthropometric data, lipids, adipose tissue percent (%fat), HOMA-IR were also assessed.
Results: The studied groups were not different in terms of age, BMI, waist circumference, %fat and HOMA-IR. In the patients group, mean TT and androstendione levels were significantly higher as compared to controls (1.4 nmol/L vs. 1.0 nmol/L, P < 0.001) and (6.6 nmol/L vs. 4.9 nmol/L, P < 0.01), respectively. In the patients group, mean TT/DHT ratio was significantly higher compared to controls (3.6 vs. 2.7, P < 0.01) and correlated with BMI (r = 0.37, P < 0.05), waist circumference (r = 0.44, P < 0.01), %fat (r = 0.30, P < 0.05), as well as with insulin levels (r = 0.38, P < 0.05) and HOMA-IR (r = 0.44, P < 0.05). The association between TT/DHT ratio and unfavorable metabolic parameters was also seen in controls.
Conclusion: Total testosterone/dihydrotestosterone ratio assessed by LC-MS/MS correlates with a worse metabolic profile not only in PCOS patients, but also in healthy women.
