What is the difference between polycystic ovaries and polycystic ovary syndrome?

Polycystic ovary refers to polycystic changes in the ovaries shown on ultrasound, and polycystic ovary syndrome is a disease accompanied by endocrine and metabolic abnormalities. The main difference between the two is whether it is accompanied by clinical symptoms and metabolic abnormalities.

1. Define the difference

Polycystic ovary only describes the morphological characteristics of the ovary. Ultrasound shows the presence of multiple immature follicles in one or both ovaries. Polycystic ovary syndrome must meet two of the Rotterdam diagnostic criteria: abnormal ovulation, hyperandrogen manifestations or abnormal biochemical indicators, polycystic changes on ultrasound, and other endocrine diseases must be excluded.

2. Clinical manifestations

Simple polycystic ovaries may have no symptoms. Patients with polycystic ovary syndrome often have oligomenorrhea or amenorrhea, hirsutism, acne and other hyperandrogenic manifestations. Some are accompanied by obesity and acanthosis nigricans caused by insulin resistance. Women of childbearing age often suffer from infertility.

3. Metabolic effects

Polycystic ovaries usually do not affect metabolic function. Patients with polycystic ovary syndrome have glucose and lipid metabolism disorders and may develop type 2 diabetes and cardiovascular disease in the long term. Long-term anovulatory hyperplasia of the endometrium may increase the risk of endometrial cancer.

4. Diagnostic criteria

Polycystic ovaries can be diagnosed through ultrasound. Polycystic ovary syndrome requires comprehensive evaluation including gynecological examination, six sex hormones, anti-Mullerian hormone test, OGTT test, etc. If necessary, adrenal or pituitary function tests should be performed to rule out Cushing's syndrome and other diseases.

5. Intervention measures

Asymptomatic polycystic ovaries do not require treatment. Polycystic ovary syndrome requires layered management based on needs: adjusting lifestyle to improve metabolism, using ethinyl estradiol and cyproterone tablets to regulate menstruation, clomiphene citrate tablets to induce ovulation, and metformin to improve insulin resistance. In severe cases, laparoscopic ovarian drilling may be performed.

It is recommended that patients with polycystic ovary syndrome regularly monitor blood sugar and blood lipids, keep their body mass index within the normal range, and ensure moderate aerobic exercise every day. The diet needs to control the intake of high-glycemic index foods, increase the proportion of dietary fiber and high-quality protein, and avoid staying up late and other behaviors that disrupt endocrine rhythms. If menstrual disorders or metabolic abnormalities occur, you should promptly seek medical attention from a gynecologist or endocrinologist.
