title: Number of siblings and birth order of sexually dysfunctional males and sexual delinquents.
abstract: We compared the number of siblings and the birth order of a group of 600 sexually dysfunctional males with those of groups of sexual delinquents. The sexual delinquents included: 238 sexual aggressors, 249 exhibitionists, 437 pedophilic and 57 homosexual delinquents. We found that patients treated for sexual dysfunctions had a significantly higher incidence of only-children than each of the sexually delinquent groups. Pedophilic and homosexual delinquents were more frequently the last of three or more children, a difference that was significant when compared with the sexually dysfunctional men.
