occurrence ; its production is post-natal in time. It is known that the 

 ovary of the new-born agrees in confirmation with the usual mammalian 

 type, and is ovoid in shape with both its borders convex. During the 

 first year of extra-uterine life the extremities of the ovary bend towards 

 each other, and thus the ovulation fossa is produced. 



The two ends of the ovary are rounded and free. The cranial end 

 (extremitas tubaria) is related to the fimbriated extremity of the uterine 

 tube of Fallopius, while the ligament of the ovary connects the caudal

The suspensory ligament or mesovarium is a double fold of 

 peritoneum, about 10 cm. broad, with a free cranial border. In a 

 caudal direction it is continuous with the mesometrium. Its dorsal 

 edge splits to become continuous with the peritoneum covering the 

 lumbar muscles. 



The proper ligament of the ovary (ligaraentum ovarii proprium) is 

 a strong peritoneal band containing muscle and connecting the ovary, 

 caudal to the ovulation fossa, with the extremity of the uterine 

 cornu.
