HERMAPHRODITISMUS VERUS IN MAN 271 



ment these cells constitute about two-thirds of the parenchyma 

 of the testicle. Their number is also very much increased in the 

 kryptorchic testicle. Whether the large amount of interstitial 

 tissue in the present case is an embryonal condition due to arrested 

 development, or simply a secondary pathological feature, is 

 difficult to say. The latter, however, seems to be more probable 

 since there are no indications, except perhaps the entire lack of 

 germinal epithehum, that the gland did not develop normally. 

 It probably degenerated later on account of its unusual position. 

 Finotti claims that the gland does not degenerate for such a 

 reason, but on account of an early predisposition to do so. 



The entire accessory system of the male genital gland, rete 

 testis, ductuli efferentes, ductus epididymis and vas deferens, 

 are present. The globus major is, as far as the arrangement of the 

 efferent ducts is concerned, rather well developed. The epithe- 

 lium, however, is very degenerate in places (fig. 4), though to- 

 wards the duct of the epididymis it approaches a normal condi- 

 tion. The epithelium in some tubules is of the low cubical type 

 without foldings (fig. 3), while in others it shows the normal pro- 

 jections into the lumen with alternating columnar and cubical 

 cells. 



The structure of the epididymis resembles in parts that of the 

 epoophoron and since both organs are derived from the Wolffian 

 body, it is not impossible that in a true hermaphrodite we might 

 find them somewhat mixed. 



The ductus epididymidis is normally developed. The muscular 

 coat of the efferent ducts increases in thickness as they approach 

 the epididymis. There are numerous elastic fibres among the mus- 

 cle cells ; if these, as Stohr states, do not appear until puberty is 

 reached we must conclude that the entire efferent system reached 

 a mature state independently of the testicle. This is also empha- 

 sized by the fact that the better developed parts are those 

 farthest removed from the testicle. The duct of the epididymis, 

 for instance, has a normal, highly columnar, ciliated epithelium, 

 which shows no signs of degeneration. In the lumen is seen cell 

 detritus, a finely granular mass and numerous concrements. The 

 muscular coat of the spermatic cord is much increased.
