go·nad·al dys·gen·e·sis

defective gonadal development, varying types and degrees of which have been identified, including gonadal aplasia or agenesis, rudimentary gonads, congenitally defective gonads, and true hermaphroditism; the character of the external genitalia, genital ducts, and secondary sexual development are only sometimes uniquely related to a given type of gonadal dysgenesis XO GONADAL DYSGENESIS51 consists of monosomy X with a gonadal streak rather than a true ovary, notably seen in Turner syndrome; XX GONADAL DYSGENESIS51 is an autosomal recessive disorder with a female karyotype, streak gonads, and primary amenorrhea, but with no body features of Turner syndrome; XY GONADAL DYSGENESIS51 is an X-linked disorder associated with a male karyotype and a female habitus, streaked gonads, and absence of secondary sexual characteristics.

Finally, it is important to emphasize that among the 22 evaluated gonads, only 5 grossly resembled streak gonads. It is interesting to point out that they were all found on the left side; among true hermaphrodites, there is also a predominance of ovaries and ovotestes on the left side.[19,20]
