Abstract |
The importance of canine
reproduction is steadily increasing and little is known about the canine
cervix and ovary so far. The aim of this study is to describe the
histomorphology of the canine cervix, ovary and to determine its
correlation with the stage of oestrous cycle and to circulating
concentrations of progesterone (P4) and estradiol-17beta (E2) and
vaginal cytology respectively. Twenty healthy and sexually mature
bitches with ages ranging from 2 to 8 years were assigned to the
experiment. Ovariohysterectomies were performed according to standard
procedures through median laparotomy access. Ovaries and cervix uteri
were collected from 20 cross bred bitches at the time of routine
ovariohysterectomy. Canine estrous cycles were determined by clinical,
macroscopical and histological findings. Histomorphological examinations
were performed to evaluate epithelial thickness and epithelial layers of
cervix uteri and ovary tissue were significantly influenced by the stage
of cycle.The aim of this study is to investigate the histomorphological
structure of the cervix and ovary in the cycle phase of non-pregnant
bitches. This study showed that the cervix and ovary undergoes cyclic
changes during the canine oestrous cycle, in particular in association
with circulating P4 and E2 concentration.
