    TLDR Polycystic ovary syndrome is found in 6.5% of unselected Caucasian women in Spain.
    In a study conducted from May to June 1999, researchers assessed 154 unselected Caucasian women in Madrid, Spain, for the prevalence of polycystic ovary syndrome (PCOS). Using the NIH/NICHHD 1990 criteria, they diagnosed PCOS in 10 women (6.5%), found hirsutism in 11 women (7.1%), and acne in 19 women (12.3%). The study concluded that PCOS is a common endocrine disorder among this population, with a prevalence of 6.5%. Additionally, women with PCOS or hyperandrogenemia had higher hirsutism scores, increased serum testosterone, free androgen index, and DHEAS levels, but lower SHBG levels compared to nonhyperandrogenic women. There were no significant differences in BMI, waist to hip ratios, or family history of diabetes, hypertension, or male pattern baldness among the groups.
