At the time, Du Laurens was describing what was considered to be a pair of organs (not the single two-lobed organ), and the Latin term "prostatae" that was used was a mistranslation of the term for the Ancient Greek word used to describe the seminal vesicles, "parastatai"; although it has been argued that surgeons in Ancient Greece and Rome must have at least seen the prostate as an anatomical entity. The term "prostatae" was taken rather than the grammatically correct "prostator" (singular) and "prostatores" (plural) because the gender of the Ancient Greek term was taken as female, when it was in fact male.
