title: [Thyroid disease and reproduction dysfunction].
abstract: Thyroid disorders have been implicated in a broad spectrum of reproductive disorders ranging from abnormal sexual development to menstrual irregularities and infertility. Hyperthyroidism in the male is thought to cause gynecomastia. In the female hypo and hyperthyroidism results in changes in cycles length and amount of bleeding. The hypothyroidism in the male has less clear-cut effect on the reproductive system. Long-standing, untreated hypothyroidism is associated with galactorrhea. These abnormalities are reversible with adequate thyroid supplementation or collection of hyperthyroidism. Thus during the investigation of hirsurism, menstrual irregularity, infertility, galactorrhea, and gynecomastia, the possibility of thyroid dysfunction must always be considered.
