Abstract

Endocrinologic findings and a successful pregnancy in a 39-year-old woman with significant androgen excess due to a biologically active, virilizing ovarian sex cord–stromal tumor, unclassified, are described. She had secondary amenorrhea, infertility, and hirsutism. Her basal plasma testosterone level was high at 187 ng/mL (normal range: 10–85 ng/mL). Tumor resection resulted in resumption of ovulation, pregnancy, and delivery.
