A common ovulation problem that affects about 5% to 10% of women in their reproductive years is polycystic ovary syndrome (PCOS). PCOS is a hormonal imbalance that can make the ovaries stop working normally. In most cases, the ovaries become enlarged and appear covered with tiny, fluid-filled cysts. Symptoms include:
No periods, irregular periods, or irregular bleeding.
No ovulation or irregular ovulation.
Obesity or weight gain (although thin women may have PCOS).
Insulin resistance (an indicator of diabetes).
High blood pressure.
Abnormal cholesterol with high trigylcerides.
Excess hair growth on the body and face (hirsutism).
