Incorrect laboratory findings. The article “Evaluation and Treatment of Infertility” (March 1, 2015, p. 308) contained an error in Table 3 (p. 310) titled “Etiology and Evaluation of Infertility.” In the fourth row, “Ovulatory disorder,” the “History and physical examination” column indicated that hair loss may be noted, which may indicate hypothyroidism. However, the “Laboratory and radiologic testing” column indicated that the thyroid-stimulating hormone (TSH) level would be low. TSH levels would be elevated in a patient with hypothyroidism. The online version of the article has been corrected.
