590 Hermaphroditism in the Monkey 



lire 31, for the other pseudohermaphrodite, fetus 80. The ovaries, Fallopian 

 tubes, and uterus of the two pseudohermaphrodites were the same size and 

 occupied the same position as that found in the normal fetus. The vagina was 

 short and passed ventrally, surrounded by prostatic tissue, to enter through the 

 dorsal wall of the urethra below the neck of the bladder. The urethral end 

 of the vagina was a flattened cord of cells, U-shaped in cross section. As it ap- 

 proached the urogenital sinus it was reduced in size and greatly resembled the 

 prostatic utricle of the male. A lumen was present at the cervical and urethral 

 extremities of the vagina. Plate 6, figure 27, shows a section in this region which, 

 except for the absence of the ejaculatory ducts, could be mistaken for that of a 

 normal male. At a slightly higher level, part of the vagina on the left side was 

 detached as an expanded vesicle. 



Prostatic tissue resembled in amount and degree of development that of 

 the normal male of this age (compare pi. 6, fig. 27, and pi. 2, fig. 9). Glandular 

 tissue was present as solid epithelial cords, very few of which had lumens. 

 Open ducts passed from this tissue to enter the urethra both cranially and 

 caudally to the level of entrance of the vagina. 



Seminal vesicles and ejaculatory ducts were absent. 



The bulbo-urethral glands (pi. 6, fig. 26) were about half again as large as 

 in the normal female fetus with the proportion of epthelial tissue approxi- 

 mately twice as great and the stroma reduced in amount. The gland was sim- 

 ilar to that of the normal male (compare pi. 6, fig. 26, and pi. 2, fig. 10) but 

 smaller than that of the treated male (pi. 4, fig. 19). 



The urethra at the level of the bulbourethral glands had abundant cavern- 

 ous tissue (pi. 6, fig. 26). More distally in the penile portion of the urethra there 

 were well-developed corpora cavernosa which lay above the roof of the 

 urethra. Sections through the clitoris internal to the hypospadiac portion 

 demonstrated a large amount of cavernous tissue and the presence of an os 

 clitoris in which some bone had already been formed (see pi. 6, fig. 28). The 

 prepuce was not separated from the glans. 



Fetus 80, Female Complete Pseudohermaphrodite (pi. 1, figs. 1 and 6, pi. 7, 

 figs. 30 to 35). The mother received 20 mg. of testosterone propionate daily 

 from the forty-third to the ninety-eighth day of pregnancy. Presumably this 

 fetus and the preceding one were subjected to comparable treatment. The 

 daily amount of hormone, the span of injection, and the weight of the mothers 

 were very nearly the same. The two pseudohermaphroditic fetuses were similar 

 except for the configuration of the scrotum and phallus, the external genitalia 

 of this animal, fetus 80, being more like that of the male. The phallus had 

 reached a position anterior to the scrotum, the two parts of which were united. 

 In the other pseudohermaphrodite the phallus was short and occupied a posi- 

 tion between the two lobes of the scrotum and the distinct raphe suggested 

 fused lips of the labia (compare pi. 1, figs. 5 and 6). In fetus 80 the male ap- 

 pearance was attained save for the hypospadias and cryptorchidism.
