Can polycystic ovary syndrome cause female infertility?

PCOS can alter the hormone signals that help an ovarian follicle mature and release an egg. Ovulation may then happen infrequently or not at all, making the fertile window difficult to predict. Irregular periods, long gaps between periods, acne, increased facial or body hair, and changes in weight can occur alongside PCOS, although symptoms vary. PCOS can affect fertility, but it does not mean pregnancy is impossible. Other factors, including sperm health, fallopian tube conditions, age, and other ovulation problems, can also influence the time it takes to conceive.

A clinician may assess your menstrual pattern, medical history, hormone-related symptoms, and general health. Tests can include blood work and pelvic imaging when appropriate. The aim is to understand whether ovulation is occurring and whether another condition is contributing.

Arrange an appointment with a gynaecologist or fertility clinician if you are trying to conceive or have very irregular periods. Bring a record of bleeding dates, symptoms, medicines, supplements, and any previous pregnancy history. Care may include support for ovulation, advice about health habits, and treatment selected for your circumstances. Do not start or stop hormone medicines without medical guidance, especially if pregnancy is possible.

If you are not trying to become pregnant, irregular periods still deserve attention because the uterine lining may remain exposed to hormonal stimulation for a long time. A clinician can discuss options for cycle management and contraception based on your goals.

Seek routine medical care for repeated missed periods, cycles that remain unpredictable, or difficulty conceiving. Seek urgent care for very heavy vaginal bleeding, severe or worsening pelvic pain, fainting, marked dizziness, or a positive pregnancy test with pain or bleeding. These symptoms can have causes that need prompt assessment and should not be attributed to PCOS without an examination.

You could ask: How will we check whether I am ovulating? Could another condition be affecting my fertility? Which treatment fits my pregnancy plans? What symptoms should prompt an urgent call?
