Contents: The content of progesterone, estradiol‐17β, and testosterone of plasma and cystic fluid was determined in 79 sows with ovarian cysts. The average progesterone concentration of sows with dark corpora lutea (CL) was higher than of sows with pale or absent CL (39.4 vs. 8.7 vs. 8.0 ng/ml plasma; p < 0.001; and 7512 vs. 3644 vs. 2723 ng/ml cystic fluid, respectively; p < 0.001). The cystic fluid of animals with oligocystic ovaries (10 cystslanimal) had a significant higher progesterone concentration in comparison to potycystic animals (7200 vs. 3682 ng/ml; p < 0.001). Testosterone and estradwl‐17β levels in plasma and in cystic fluid of polycystic animals were significantly higher in comparison to oligocystic animals (Plasma‐Testosterone: p < 0.01; Plasma‐Estradwl: p < 0.05; Cyst‐Testosterone: p < 0.01; Cyst‐Estradiol: p < 0.001). In oligocystic ovaries testosterone in cysts exceeded the estradiol‐17β levels, whereas in polycystic ovaries the situation was vice versa (p < 0.001). It is suggested that cystic ovarian degeneration in the sow is not exclusively a gradually progressing process, rather then a complex syndrome with three components, were characterized by a separate course of development (oligocystic, polycystic. oligo‐polycystic syndrome).
