A Phenotypic Male Swine With a Female Karyotype

Seven swine intersexes with XX chromosome constitution

“…The cases presented in this paper were male pseudoher-maphrodites and true hermaphrodites. Still more pronounced external male sex characters than those present in our cases can be combined with a female chromosome constitution according to the literature ( HARD and EISEN 1965;LOJDA and RuszovA 1966;LOJDA 1967).…”

“…In all these cultures only 38, XX cells were found. Similar investigations were carried out by HARD and EISEN (1965). These authors also failed to demonstrate any mosaicism or other chromosomal abnormality in intersexes which all had the 38, XX karyotype in their leucocytes as well as in their fibroblasts.…”

Intersexuality in the Pig

“…The intersex pigs have generally been characterized as male pseudohermaphr•odites with testicular gonads, Miillerian and Wolffian ducts and male accessory sexual glands of varying development. The enlarged clitoris completes this picture (Holz 1941;Freudenberg;Makino et al 1962;Henricson & Backstrom 1963;Koch;Hard & Eisen 1965;McFeely et al 1967). True hermaphrodites with both male and female gonads have also been described (Baker 1926;Holz;Albertsen;Johnston et al 1958).…”

A Phenotypically Normal Female Golden Hamster With Sex-Chromosome Anomaly

“…(Nes 1966;McFeely et al 1967;Shaver 1967). But there have been cases reported of intersex in goats and pigs with male gonads showing an XX sex chromosome constitution (Makino et al 1962;Basrur and Coubrough 1964;Hard and Eisen 1965;McFeely et al 1967). Ferguson-Smith (1966) suggested the interchange of a male determining gene (or genes) of the Y chromosome onto the paternally derived X chromosome for similar cases of intersex in man.…”
