PARTIAL HERMAPHRODITISM 137 



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

 while ' structural hermaphroditism ' is a very common aphroditism. 

 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 

 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. ^tTuTherm- 



(2) Unilateral hermaphroditism, in which there is an aphroditism.' 

 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.
