XX ovotesticular DSD
Thursday 7 October 2010
Differentiation of testicular tissue in 46,XX individuals is seen either in 46,XX males, the majority of them with SRY gene, or in individuals, usually SRY(-), with ovotesticular disorder of sex development (OT-DSD).
Although they are sporadic cases, there are some reports on familial recurrence, including coexistence of XX maleness and OT-DSD in the same family.
Both XX maleness and XX OT-DSD are different manifestations of the same disorder of gonadal development.
