Adult male and female, nine-banded armadillos (Dasypus novemcinctus) were treated with exogenous gonadotropins and steroids to induce mating in captivity. Gonadotropin treatment induced follicular development and ovulation in the female but failed to enhance semen quality in the male. The number of ovarian follicles increased as the dosage of pregnant mare serum gonadotropin increased; ovulation rate appeared to be inversely related to dose. Mating behavior was not detected in any of the trials, but a pattern of cyclic cytological changes in urogenital smears, which could be used to detect the follicular phase of the estrous cycle, was observed. The modal duration of the estrous cycle was found to be 4 days.
成年雄性和雌性九带犰狳（Dasypus novemcinctus）接受了外源性促性腺激素和类固醇治疗，以诱导其在圈养环境中交配。促性腺激素治疗可诱导雌性卵泡发育和排卵，但未能提高雄性的精液质量。随着孕马血清促性腺激素剂量的增加，卵巢卵泡数量增多；排卵率似乎与剂量呈负相关。在任何试验中均未检测到交配行为，但观察到泌尿生殖道涂片中有周期性细胞学变化模式，可用于检测发情周期的卵泡期。发现发情周期的平均持续时间为4天。
