disappear almost entirely in the male. Their fused caudal 

 extremities form the prostatic utricle (sinus pocularis, p. 379), 

 while their cephalad extremities are represented by small 

 appendages, which are situated on the upper poles of the testes. 



THE FEMALE PELVIS AND REPRODUCTIVE ORGANS 



The Osseous Pelvis of the female is constructed so as to 

 provide a roomy cavity and wide upper and lower apertures 

 for the passage of the foetal head. The female pelvis differs 

 from the male pelvis in many ways, but the most important 

 difference is traceable to the sacrum, which is much wider in 

 proportion to its length. As a result, the cavity of the female 

 pelvis may be described as a " short section of a long cone,"
