Abstract: This study aimed to find a practical tool for predicting conception in red fox vixens following natural mating. Basal vaginal electrical resistance (VER) during post-breeding seasons in Japan consistently ranged from 90 to 220 units. The VER displayed a single peak after the vulva became well-swollen during breeding seasons, and median VER magnitude was 350 units among all vixens that became pregnant, 230 units among vixens that did not become pregnant, and 190 units among vixens that did not mate. Conception rates in vixens with VER above 350 units were dramatically higher when coitallock time was more than 40 min. These findings suggest that a peak magnitude of VER with coital-lock time may be an expedient predictor of conception in red foxes.
