PCOS is one of the most common hormonal conditions in women of reproductive age, affecting up to 1 in 10 women. It is highly manageable with the right treatment and lifestyle approach.
Polycystic ovary syndrome (PCOS) is a hormonal disorder characterised by irregular or absent menstrual periods, elevated androgen (male hormone) levels, and polycystic-appearing ovaries on ultrasound. It is one of the leading causes of female infertility and affects approximately 8–13% of women of reproductive age globally. In Korea, PCOS is frequently seen in gynaecology and endocrinology clinics.
PCOS is associated with insulin resistance — a condition where cells do not respond efficiently to insulin, leading to elevated blood sugar and compensatory high insulin levels. This drives the excess androgen production responsible for many PCOS symptoms: irregular periods, acne, excess facial and body hair (hirsutism), and scalp hair thinning. PCOS is also associated with a significantly increased risk of type 2 diabetes, gestational diabetes, and cardiovascular disease in the long term.
Management of PCOS is tailored to the patient's primary concern. For weight management and insulin resistance: lifestyle modification (regular exercise, low-glycaemic diet) is the most effective first-line treatment — even modest weight loss of 5–10% can restore ovulation in many women. Metformin improves insulin sensitivity. For irregular periods and androgen symptoms: combined oral contraceptive pills (COCPs) are effective. For fertility: ovulation induction with clomiphene or letrozole, or referral for IVF. Korea's gynaecology and endocrinology specialists provide comprehensive PCOS management at both community health centres and private clinics.
