True Hermaphroditism in Chimaeric Mice.

Sex chimaerism and germ cell distribution in a series of chimaeric mice.

1. Of 30 mice born from aggregation of embryos from a multiple recessive strain with F1 embryos carrying the contrasting alleles, 4 females and 20 males proved to be overtly chimaeric. 2. Three XX/XX females, five XY/XY males and eight XY/XX males were identified by chromosome analysis. Thus 50% of the population analysed were sex chimaeras, and all of these developed as phenotypic males, thoug...

Unusual dual genital duct remnants in true hermaphroditism.

A case of true hermaphroditism is reported in which a 46,XY karyotype was associated with a testis and an ovotestis. The dual presence of a Fallopian tube and a vas deferens on the side of the ovotestis is documented as a previously unreported finding.

Two new cases of true hermaphroditism.

Histological and genetic characterization of true hermaphroditism in Korean pigs.

True hermaphrodites are animals of equivocal sex in which both male and female gonads develop simultaneously in the same individual. The frequency of true hermaphroditism is relatively higher in pigs than in other domestic animals. Two Korean pigs were diagnosed with true hermaphroditism showing ovotestes, epididymides, a penis and uteri. The testicular tissues consisted of Sertoli cells that w...

Child with True Hermaphroditism

True hermaphrodites possess both ovarian and testicular tissues which may be present in separate gonads or combined in an ovotestis. External and internal genitalia are ambiguous and variable, though a prominent penial structure is usual. Chromosome examination of true hermaphroditism has revealed an XX sex chromosome complement in the majority of cases, but the XY complement and different mosa...
