The case of a woman with one spurious and six real pregnancies is reported. The dynamics of her recurrent wish to live in a pregnant state are presented. The pertinent literature on this subject was reviewed and our findings were joined with those of other investigators in order to clarify and organize the conscious and unconscious motivational factors which lead to the need to be pregnant. These motives were discussed under four headings: Narcissism and Dependency; Identity and Body Image; Power; and Guilt and Pain Dependence. Clinical examples were offered.
