Characteristics of estrus, mating, and pregnancy were studied in captive fennec foxes. The monestrous cycles had mean intervals of 9.9 (±1.2) months, whether or not pups survived to weaning. Proestrus, judged by vulval swelling, began 6.5 (±0.7) days before estrus and was not accompanied by sanguineous discharge. Percentage cornified epithelial cells in vaginal smears increased at the time of estrus. In 8 of 10 estrous periods, a single mating followed by an extremely long copulatory lock (mean 1 h 58 min) was observed during continuous video monitoring. In the other two cycles, copulation occurred 2 and 3 times. Patterns of both fecal and serum estradiol and progesterone concentrations during estrous cycles were similar to those reported for other canids.
