To further investigate if an increased M1/M2 ratio in PCOS subjects is associated with higher inflammatory cytokines in follicular fluid (FF), the concentration of galectin-1, galectin-3, Osteoprotegerin, IL6 and Cystatin C were compared between FF from PCOS and non-PCOS subjects. The gene discussed is LGALS1; the disease is polycystic ovary syndrome.
