Abstract. The aim of the study was to determine the relationships between bone morphogenetic protein 15 (BMP-15) and growth differentiation factor 9 (GDF-9) concentrations and free thyroxine (FT4) and progesterone (P4) concentrations in follicular cysts, preovulatory follicles, and the serum of sows (cyst-bearing (n = 26) and non-cyst-bearing (n =  26)). FT4 and P4 concentrations were higher in the cystic fluid than in the fluid of preovulatory follicles (p <  0.01 and p <  0.05 respectively). BMP-15 and GDF-9 concentrations were higher in the serum of cyst-bearing sows than non-cyst-bearing sows (p <  0.05) and higher in the cystic fluid than in the follicular fluid (p <  0.05). In the cysts and preovulatory follicles, GDF-9 concentration was higher than in serum (p <  0.01). FT4 concentration in the serum of cystic sows was correlated with BMP-15 (r =  0.50, p <  0.05) and GDF-9 (r =  0.62, p <  0.01) concentrations in serum. In the serum of non-cyst-bearing sows, a positive correlation between P4 concentration and BMP-15 concentration (r =  0.60, p <  0.01) was detected.

These data will help provide insight into the role of BMP-15, GDF-9, FT4, and P4 during cyst formation in sows.
