- W4380227614 abstract "The etiology of polycystic ovary syndrome (PCOS) is unclear. This study aimed to evaluate the role of classic and 11-oxygenated (11oxyC19) androgens in two typical signs of PCOS, polycystic ovary morphology (PCOM) and menstrual cycle prolongation. A total of 462 infertile women with diagnosed PCOS and/or commonly accompanied metabolic disorders were recruited. Classic and 11oxyC19 androgens were determined with a sensitive high-performance liquid chromatography-differential mobility spectrometry tandem mass spectrometry apparatus. Least absolute shrinkage and selection operator logistic regression with fivefold cross-validation was applied to construct prediction models. For PCOM, the most significant contributing androgen was testosterone (T), with the weight of 51.6%. The AUC of the prediction model was 0.824 in validation set. For menstrual cycle prolongation, androstenedione (A4) was the most significant contributing androgen with weights of 77.5%. The AUC the prediction model was less than 0.75. When including other variables, the most significant variable turned to be AMH both in PCOM and in menstrual cycle prolongation. Androgens had more contribution in PCOM than in menstrual cycle prolongation. The classic androgen T or A4 contributed more than 11oxyC19 androgens. However, their contributions were diminished when other factors were considered, especially AMH." @default.
