STRUCTURAL ANOMALIES OF GENITALIA 131 



In the primary development of the female genitalia stages in 

 we must recognize three stages : the fatal which takes |[k^men 

 place during intrauterine life ; the infantile which extends of genitalia. 

 from birth to puberty, and the complete which occurs at 

 puberty. It is, therefore, possible for the development 

 to be imperfect only, or imperfect and irregular in the 

 first stage ; while later it is only possible for the further 

 development to be incomplete. 



Iii the first stage, then, the following anomalies may 

 be produced : a rudimentary uterus and ovaries, all 

 of which are otherwise normally formed ; or normal 

 ovaries with a rudimentary uterus ; or, again, rudi- 

 mentary or normal ovaries with imperfect development 

 of the genital ducts, such as bicornute uterus, septate 

 vagina and so on ; and, lastly, irregular development 

 of the genital gland and genital ducts, constituting 

 hermaphroditism. 



In the early period of postnatal development (in- 

 fantile stage) there is normally a gradual development 

 and enlargement of the genital organs ; the ovary, too, 

 becomes functional. In this stage, however, we may 

 see insufficient development, leading to the condition 

 known as infantilism of the genitalia ; and at the 

 age when development should be complete that 

 is, at puberty this abnormal state of affairs may 

 persist, or the genitalia may not undergo the further 

 development, chiefly functional, normal to this time 

 of life. 



Incomplete development of the Genital Ducts and 

 Ovaries, which otherwise may be perfectly

The pathological conditions under this heading are Ateieiosis. 

 sometimes associated with what has been called ateleiosis, 

 the cause of which is probably some general disorder of 

 the horaionopoietic system. In one case under my care 

 (fig. 38) I found that the patient had a very shallow
