Development of Wolffian Ducts, Seminal Vesicles and Prostate 

 Glands in Cultured Reproductive Tracts 



The urogenital sinus was removed at explantation in some cases. 



Seminal vesicles were present in explants cultured at 18 + days ; some small prostatic buds 

 occur in a few foetuses at 18 4- days but are normally present by 19 + . 



The figures in parentheses indicate the age of the youngest explant in which seminal vesicles 

 or prostate glands were found.
