Despite the high prevalence of PCOS and the considerable clinical impact, the precise interplay between metabolism and hyperandrogenemia is not entirely clear.<\/jats:p>\n               <jats:p>Objective: The objective of the study was to analyze the effects of iv lipid and heparin infusion on circulating androgen levels in healthy women.<\/jats:p>\n               <jats:p>Design: This was a randomized, controlled, crossover trial.<\/jats:p>\n               <jats:p>Setting: The study was conducted at an endocrinology center.<\/jats:p>\n               <jats:p>Patients: Patients included 12 healthy young women during the early follicular phase of two subsequent cycles.<\/jats:p>\n               <jats:p>Intervention: After an overnight fast, a 20% lipid\/heparin or a saline\/heparin infusion was administered in random order for 330 min.<\/jats:p>\n               <jats:p>Main Outcome Measures: A detailed characterization of androgen metabolism was performed.<\/jats:p>\n               <jats:p>Results: Elevations in free fatty acids and triglycerides, induced by lipid\/heparin infusion, elevates the levels of androstenedione, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), testosterone, 5\u03b1-dihydrotestosterone, estrone, and 17\u03b2-estradiol.
