title: Recovery of prolactin function following spontaneous pregnancy in a woman with Sheehan's syndrome.
abstract: Sheehan's syndrome (SS) presents with hypopituitarism after parturition, usually preceded by postpartum hemorrhage. The first symptom of the disorder is lactation failure because of lactotroph cell necrosis. Recovery of lactotroph function after initial insult has not been reported in the literature. We describe the evaluation of a case of SS in whom lactotroph function recovered after the second pregnancy. A young woman delivered her first child at the age of 25 years; delivery was followed by severe postpartum hemorrhage and required blood transfusion. Sheehan's syndrome was diagnosed because of lactotroph, corticotroph, thyrotroph and somatotroph failure and empty sella on MRI. She conceived twice spontaneously and had normal lactation after the second delivery; investigations confirmed the normal basal and stimulable prolactin levels. We presume that recovery of lactotroph function after the second pregnancy in a patient with SS is possibly because of stimulatory effect of estrogen and progesterone on residual lactotroph cells.
