Polycystic ovary syndrome is a common hormonal condition that can cause irregular or absent ovulation, which is why it is a frequent reason for difficulty conceiving. It is also associated with irregular periods, acne, excess hair growth, and weight changes. Having PCOS does not mean you cannot conceive; many people do, sometimes naturally and sometimes with help.
Managing weight where relevant, staying active, and addressing related issues such as insulin resistance can improve ovulation for some people. When extra help is needed, doctors can offer treatments that encourage ovulation and other fertility support.
If you have PCOS and are planning pregnancy, or have been trying without success, see a clinician. They can confirm the diagnosis, check related health factors such as blood sugar and thyroid, recommend folic acid before conception, and discuss treatment options tailored to you.
