Über den wahren Hermaphroditismus des Menschen und der Säugetiere

So-Called True Hermaphroditism, with the Report of a Case

“…Tuffier and Lapointe [17], also, in their paper published in 1911, apparently accept only the case of Blacker and Lawrence of those published prior to 1897; but they add to this case those of von Salen [12], Garre [3], Landau and Pick, [8], and Schickele [13], recorded subsequently to Blacker's and Lawrence's paper. Pick [11], in an importantpaper published in 1914, discusses exhaustively the question of this so-called 'true hermaphroditism,' and comes to the same general conclusions as Tuffier and Lapointenamely, that all the cases of this variety reported and accepted should be called ' glandular partial hermaphrodites.' This author records five cases of ovo-testis occurring in pigs, all of which he had himself examined.…”

“…Two very similar cases, one by Gautier (1752) and one by Pinel, are referred to by Rudolphi. 1 According to Pick (1914), Sauerbeck admits only 7 cases of hermaphrodites in mammals as certain and complete, 5 for swine, and 2 for man (Salens, 1899, andSimon, 1903), to which number are added 3 B TEXT-FIGURE 70.…”

“…Bridges (1915) has shown that the percentage may change with age, and Plough (1917) has shown that it may be changed by temperature. Genetic factors (other than sex) influencing the process are suggested by the results of Baur (1912) with Antirrhinum, of Punnett (1913) with sweet peas, of Tanaka (1913, 1914 with silkworm moths, and of Chambers (1914) with Drosophila.…”

The germ-cell cycle in animals, by Robert W. Hegner.

“…True hermaphroditism is rare in man and other mammals, but several cases have been described in the pig by Sauerbeck (1909) and Pick (1914), and in man by Simon (1903), Uffreduzzi (1910), Gudernatsch (1911), and Pick (1914).…”
