However, Leydig and Sertoli cell markers are rarely used in distinguishing such individuals. OBJECTIVES: To evaluate the funct

8. Aerobic physical training impact on adipokines in women with polycystic ovary syndrome – Effects of body fat percentage
ABSTRACT Objective: We investigated the effects of aerobic training on adipokine concentrations in women with polycystic ovary syndrome (PCOS). Subjects and methods: 120 women, including 60 with PCOS and 60 without PCOS, were divided into six groups (n = 20) based on body fat percentages of 22%-27%, 28%-32%, and 33%-37%. All groups were submitted the same

11. Total cholesterol/high-density lipoprotein and inflammatory parameters in patients with polycystic ovary syndrome
SUMMARY OBJECTIVE: In this study, the hormone profile, lipid profile, and inflammatory parameters of patients with polycystic ovary syndrome were compared with those of non-polycystic ovary syndrome patients to determine predictive markers in young polycystic ovary syndrome patients who have not yet had children. METHODS: Patients’ age, height, weight, b
