TESTICLE AS GLAND OF INTERNAL SECRETION 517 



may be explained upon simple embryologic maldevelopmental grounds, 

 but it is possible that some of them may be due to a commingling of the 

 maternal and fetal bloods. Dr. Lille in his very 

 excellent work on free martins in cattle has shown 

 that the hypo-developed female is due to the com- 

 mingling of the two embryonic bloods, and as we 

 know that the interstitial cells of the testicle are 

 laid down much earlier than the corresponding 

 cells in the ovary, and that 

 the hormone from these in- 

 terstitial cells of the testi- 

 cles circulates in the blood 

 of the female embryo, thus 

 disorganizing the normal 

 ovarian development and 

 tending to change it to a 

 more or less of a testicular 

 development. May it not 

 be possible that the eu- 

 nuchoid individual had a 

 direct connection between 

 his fetal blood and his 

 mother's blood so that the 

 strong ovarium hormones 

 from his mother disar- 

 ranged the normal testicu- 

 lar development and so 

 tended to develop a female 

 type of individual? 



In an acquired eunuch- 

 ismus or eunuchoidismus 

 we have the following fac- 

 tors in its etiology : testicu- 

 lar trauma, torsions of the cord, inflammatory dis- 

 eases of the testicle of all sorts, and nerve lesions 

 involving the spermatic plexus, the lumbo-spinal 

 cord, and the cerebellum. The exact effect of 

 these on the individual depends on the age at 

 which they occur and the exact extent of the lesion. 

 The eunuchoid, as the name implies, has many 

 of the characteristics of the eunuch. He is usually 

 tall, with long legs and long arms, and a relatively 



short body. The bodily hair distribution is usually feminine; the pubic 

 hair being cut straight across with no abdominal hair, moderate hair in 



Fig. 26. Boy is 19 

 years old, six feet four 

 inches tall. Testicles are 

 size of a peanut. Penis 

 is about the size of the 

 last joint of the thumb. 

 Bodily configuration de- 

 cidedly feminine. Note 

 particularly the breast 

 development; the femin- 

 ine cast of facies; the 

 long legs and long arms. 



Fig. 27. Note long 

 arms, feminine distribu- 

 tion of hair. Relatively 

 small penis, moderately 

 sized testicle, breast de- 

 velopment, feminine pel- 

 vis. Patient married. 

 Has intercourse once a 

 month to once in two 

 months. Ejaculation only 

 few drops, contains leci- 

 thin bodies and prostatic 

 bodies but no spermato- 

 zoa. Note the careworn 

 expression of face typi- 

 cal of eunuch.
