Familial uterine hernia syndrome: report of an Arab family with four affected males.

We report an Arab Bedouin family including four males with uterine hernia syndrome. All had a male chromosome constitution and phenotype, inguinal herniae, cryptochidism, and persistence of Müllerian derivatives. Histopathological studies confirmed the presence of both testicular tissue and Müllerian derivatives. The presence of two affected brothers and two affected maternal uncles suggests X-linked inheritance. Autosomal recessive determination with male sex limitation is also a possibility based on parental consanguinity in one sibship.
