Thyroid nodules alone generally do not affect ovarian function, and thyroid nodules accompanied by abnormal thyroid function may affect ovarian function. Thyroid nodules are confined masses that appear in normal thyroid tissue. Most patients may have no obvious symptoms, while some may have symptoms such as thyroid pain and hoarseness, which generally do not affect ovarian function. If accompanied by abnormal thyroid function, such as hypothyroidism or hyperthyroidism, abnormal thyroid hormone levels may affect ovarian function. However, patients with hypothyroidism or hyperthyroidism can avoid impaired ovarian function by actively cooperating with their doctors and keeping their thyroid hormones within a reasonable range. Patients diagnosed with thyroid nodules should actively cooperate with their doctors.
