Maternal virilization due to luteoma associated with delayed lactation.

Objective: To report on a patient with virilization during pregnancy who experienced delayed lactation secondary to elevated maternal androgens.

Design: Case report and review of the literature.

Setting: University hospital.

Patient(s): A 32-year-old pregnant woman presented with virilization at 32 weeks' gestation.

Intervention(s): Laboratory evaluation, ultrasound examination, magnetic resonance imaging, cesarean section for fetal indication, nipple stimulation to facilitate lactation.

Main Outcome Measure(s): Case report.

Result(s): Postpartum normalization of serum T levels and patient ability to breastfeed exclusively after delayed initiation of lactation.

Conclusion(s): Maternal virilization during pregnancy is rare and is often due to androgen-secreting tumors that are benign. Therefore, careful evaluation of these patients is important to avoid inadvertent oophorectomy.
