MALE HERMAPHRODITISM

On the Atypical Male and Female Sex-Ensemble (So-Called Hermaphroditism and Pseudo-Hermaphroditism)

has celebrated. This poetical and transcendental idea has so dominated the lay and scientific mind that even now the question of hermaphroditism in the mammalia is discussed and supported by the description of specimens with alleged ova and spermatozoa in a common sex gland, or of those where the opposite sex-duct element is unduly represented at the expense, we shall see, of the potent normal ...

Vaginal stone in a male patient with true hermaphroditism.

A 31-year-old male with true hermaphroditism and a 46, XX karyotype who underwent gonadectomy and extirpation of the internal sex organs at the age of 4 had a large stone 4 cm in diameter in the residual male vagina. He complained of pain on micturition, hematuria, and rectal pressure. Urethroscopy and retrograde urethrography disclosed an ostium of the male vagina in the prostatic urethra, and...

Hermaphroditism

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...

The evolution of hermaphroditism by an infectious male-derived cell lineage: an inclusive-fitness analysis.

There has been much recent interest in the role for genetic conflicts to drive the evolution of genetic systems. Here we consider the evolution of hermaphroditism in the scale insect tribe Iceryini and the suggestion that this has been driven by conflict between a female and an infectious male tissue derived from her father. We perform an inclusive-fitness analysis to show that, owing to geneti...
