Abstract	The European beaver (Castor fiber) is the largest free-living rodent in Eurasia which belongs to the group of long-day breeders. A seasonally changing photoperiod may be related to cyclic changes in the secretion of gonadotropins and sex steroids. The goal of our study was to determine sex- and seasonally dependent changes in the concentration of gonadotropins (LH—luteinizing hormone and FSH—follicle-stimulating hormone) and steroids (T—testosterone, E2—estradiol, and P4—progesterone) in the blood plasma of free-living male and female beavers. Blood samples were collected in April—pregnancy in females; July—the end of lactation, raising of offspring; and November—sexual silence. Our results indicate that in females, a higher FSH concentration was noted in July and November than in April. Plasma T content did not differ between males and females, but in females, it was higher in April as compared with July or November. Plasma P4 concentration was the highest in females in April. In summary, our findings indicate, for the first time, that in the European beaver occur sex- and/or seasonally related changes in the concentration of plasma FSH and sex steroids (T and P4). Seasonal differences in the tested hormones can be associated with the differential activity of the hypothalamo-pituitary-gonadal axis during various reproductive stages of the beaver.
