The purpose of the study was to demonstrate visually and localize the presence of serotonin (5-HT) in the ovary and oviduct of the domestic hen using a histochemical Falck-Hillarp method. Experiments were carried out on White Leghorn laying hens with no eggs in the shell gland. The specific yellow fluorescence, indicating the presence of 5-TH, was found both in the ovary and all examined oviductal parts. The strongest fluorescence was present in the ovarian stroma containing small follicles with a diameter under 4 mm. The presence of an egg in the definite oviductal segment increased the intensity of yellow fluorescence in this part
