Histocompatibility-Y (H-Y) antigen, the presumptive inducer of the mammalian testis, is present in the cells of normal males and not in the cells of normal females. Recent reports have implied that patients with transsexualism exhibit H-Y antigen phenotypes at variance with those of normal males and females and, thus, that H-Y serology might provide a tool for the diagnosis and study of the transsexual condition. We therefore evaluated blood and testicular cells from 21 male-to-female transsexuals using conventional and monoclonal H-Y antibodies. We found no evidence of abnormal H-Y phenotype. Five of the patients were interviewed postoperatively by two examiners and rated for the diagnosis of transsexualism. Three of the five were rated primary transsexual by one or both examiners, and two were rated secondary transsexual.

D006182 H-Y Antigen A sex-specific cell surface antigen produced by the sex-determining gene of the Y chromosome in mammals. It causes syngeneic grafts from males to females to be rejected and interacts with somatic elements of the embryologic undifferentiated gonad to produce testicular organogenesis.
