Contents The aim of this study was to evaluate the effects of concanavalin A ( CONA ) on the progesterone (P4) production by bovine steroidogenic luteal cells ( LC s) in vitro. Luteal cells were collected during the mid‐luteal stage (at 10–12 days following ovulation) and processed in the laboratory. Luteal cells were grown for 7 days in a humid atmosphere with 5% CO 2 , with or without 10% foetal bovine serum, and were subjected to the following treatments: control: no treatment; CONA (10 μg/ml); LH (100 μg/ml); CONA  +  LH ; LH (100 μg/ml) + prostaglandin F2α ( PGF 2α) (10 ng/ml); CONA  +  LH  +  PGF 2α. Samples of the culture media were collected on days 1 (D1) and 7 (D7) for P4 quantification. The cells were counted on D7 of culture. Differences between treatments were considered statistically significant at p  < .05. Culture in the presence of CONA decreased the P4‐secreting capacity of LC s on D7 of culture, particularly in the absence of serum. The cell numbers did not change between treatments.
