| Abstract: | A total of 73 bitches with ovarian cysts were ovariohysterectomized. Cysts were characterized by gross pathology and endocrine parameters. Therefore, oestradiol‐17ß and progesterone concentrations were assessed in cyst‐fluid and corresponding blood plasma in each bitch. Our data demonstrated that multiple cysts were often present in a single individual (82%) and that cysts were commonly found on both ovaries (77%). The number of cysts per individual varied from 1 to 35. Most cysts were small in size (range 0.2–4.0 cm in diameter). No cyst was found to produce solely oestradiol‐17ß or progesterone. Plasma levels of oestradiol‐17ß and progesterone for a given individual were positively correlated with levels of these same hormones in their cyst‐fluid (r = 0.334 and p = 0.001 for oestradiol‐17ß; r = 0.419 and p < 0.001 for progesterone). Our study is the first to provide a comprehensive evaluation of the gross pathology and endocrinology of ovarian cysts in a larger number of bitches. |
