The hypothesis tested in this study was that a group of female functional infertile patients would show significantly more personality maladjustment than a group with definite organic reproductive pathology and a normal fertile group. No significant differences between the functional and organic groups were found on any of the subscores of four personality questionnaires. The normal group (wives of sterile men) scored higher on extraversion than both the functional and organic groups. On self-control the normal group also scored lower (negative connotation) than the other two groups. In general no evidence for personality maladjustment in functional infertility was found.
