PARTIAL HERMAPHRODITISM 137 



It may, however, be of interest to point out that Classification 

 while ' structural hermaphroditism ' is a very common aph^odrtism. 

 condition, structural and functional with the power 

 of self-fertilization is very rare ; and probably for 

 the following reason. In structural hermaphrodites 

 the male and female gonads rarely become functional 

 at the same time. The creature plays the part at 

 one time of a male and at another time that of a 

 female. 



It is, of course, certain that total hermaphroditism 

 could not exist in man. The so-called ' true herma- 

 phroditism ' in man is represented by the variety better 

 known as ' glandular partial hermaphroditism ', which I 

 shall now consider. 



Glandular partial hermaphroditism. — All the Glandular 

 recorded cases of glandular partial hermaphroditism aphroditism! 

 which may be accepted as authentic — and I can discover 

 only two or three other cases of this interesting 

 and rare phenomenon in addition to one reported 

 by myself 1 , and to be described directly — have been 

 found to possess mixed gonads, so-called ' ovitestes ', 

 with or without irregularities in the sex-characteriza- 

 tion of the genital ducts, external genitalia and secondary 

 characteristics. 



In 1873 Klebs 2 , in his classical paper on the subject, So-called 

 claimed that ' true hermaphroditism ', as he called it, aphroditism.' 

 might occur in the following varieties in Man. 



(1) Bilateral hermaphroditism, in which an ovary and Kieb's ciassi- 

 testis are present on both sides. . true°herm- 



(2) Unilateral hermaphroditism, in which there is an a P hr <> ditism -' 

 ovary or testis on one side, and an ovary and 



testis on the other. 



(3) Lateral hermaphroditism, in which an ovary is 

 present on one side and a testis on the other.
