Differences of Polycystic Ovary Syndrome (PCOS) Effects among Asian and Caucasian Women

PCOS, Polycystic ovary syndrome, is the most common endocrine disorder occurring in women with normal reproductive age. General symptoms of PCOS include irregular menstrual cycles, polycystic ovaries, hirsutism, and hyperandrogenism. Also, Insulin resistance that is associated with obesity, skin conditions such as acne, and even psychiatric conditions have been reported. Comparison of prevalence of PCOS is not an easy task due to the fact that there are too many variables to consider. The biggest one is that each research uses different diagnostic criteria. Also, some studies use small sample sizes, and some studies are too specific in location to represent the whole country. This study reviewed articles to determine how geographical and ethnic differences among Asians and Caucasians would affect the prevalence of polycystic ovary syndrome.
