Pregnancy in Sheehan's syndrome: a report of three cases.

Postpartum pituitary necrosis (Sheehan's syndrome) is a relatively common clinical disorder in developing and underdeveloped areas of the world. Sheehan's syndrome has a spectrum of presentations. Spontaneous pregnancy in such patients is a rare occurrence. Three patients with clinical and hormonal evidence of postpartum pituitary necrosis conceived spontaneously during the follow up period. Pregnancy though rare may occur either due to sparing or recovery of gonadotroph function in such patients.
