The objective of this study was to clarify the psychological, social, demographic, and cultural factors associated with unconsummated marriages in Jordan. The study was conducted with psychiatric patients whose chief complaint was unconsummated marriage, and in whom organic causes had been ruled out. 116 couples were compared with a control group. Results detailed are: the most common age group (aged 20-29 yrs, 78%); education level; delays in presentation for the problem; misconceptions about the cause of their problems; primary diagnoses of sexual dysfunction; common fears among men vs women; marriage arrangements (63.8% were traditionally arranged); contact during engagement; details of wedding night; experience of foreplay; bride's having to move for marriage; requirements of an immediate confirmation of consummation by the family; past sexual experience (only men); and previous medical treatment for their problem (or contact with healers). It is concluded that unconsummated marriage is a serious problem, with adverse marital and social consequences, the causes of which include interaction of multiple factors, mainly psychological, social, and cultural. The authors emphasize the need for better education and awareness concerning this issue at both family and social levels.
