使用马绒毛膜促性腺激素和人绒毛膜促性腺激素诱导发情在6只母狗中有5只成功，尽管第一天母狗血浆孕激素浓度升高差异很大。在阴道上皮细胞角化的时间上，诱导发情期与自发发情期不同；在诱导周期中，血浆雌激素浓度普遍较高，孕激素浓度较低。这些结果表明，这种诱导发情的时间表不适合在预定的日子进行交配。
Oestrus induction using equine chorionic gonadotrophin and human chorionic gonadotrophin was successful in five out of six bitches, although the first day of increased plasma progestagen concentration differed considerably between bitches. Induced oestrous periods differed from spontaneous cycles in the timing of vaginal epithelial cell cornification; plasma oestrogen concentrations were generally greater and progestogen concentrations were less in induced cycles. These results suggest that this schedule of oestrus induction would not be suitable for allowing mating on a predetermined day.
