Clomiphene-induced ovulation in the 9-banded armadillo (Dasypus novemcinctus)

8 armadillos each received 50 mg clomiphene citrate daily for 5 days. 7 of the animals showed an increase in plasma progesterone to a level indicative of ovulation (greater than 10 ng/ml) within 6 days of the last injection. In addition, the administration of clomiphene caused the urogenital smear pattern to change from dioestrous to oestrous.
