Äggstockens normala storlek och struktur hos tik
There are only a few published studies on the normal variation in ovary size in bitches. All of the previous studies have been made on the beagle breed. This study was performed on indian street dogs with the objective to measure ovaries and structures in the ovaries after ovariehysterectomy to decide if smaller dogs have smaller ovaries and how small and big they can be in the normal dog. The structures (follicle and corpus luteum) where also measured to get a maximum size for normal structures in the bitch. This information can be valuable when examining the ovaries of the bitch with ulstrasound.
Fifty dogs where included in the study, 27 where in anoestrus, 5 where in proöestrus/oestrus and 18 where in dioestrus. The length of the anoestrus ovary varied between 9,60 ? 16,8 mm. The smaller dogs had smaller ovaries than the big dogs. The diameter of the corpus luteum varied between 2,56 -10,38 mm. There where no difference in dog size and the size of corpus luteum. The biggest follicle measured 8,08 mm in diameter.
