Pseudocyesis--a review and report of six cases.

Pseudocyesis is a rare condition in which a woman believes herself to be pregnant when she is not. Its incidence has fallen in the last fifty years, probably due to a number of sociocultural and medical factors. Six cases are described which show common features of recent pregnancy loss or infertility, psychological and medical naivete, social isolation, recent loss and membership in a cultural or religious group that focuses on childbearing as the central role of women. Etiology includes psychological, sociocultural and endocrine factors which interact with each other demonstrating the reciprocal interplay between mind and body. Guidelines are provided for the assessment and management of this ancient and fascinating condition.
