犬的生殖机制与其他动物不同，其主要特征包括：卵子成熟发生在排卵后、胚胎附植延迟、血清中孕酮浓度在排卵前升高、孕犬和非孕犬血清孕酮浓度相近、犬妊娠特征蛋白缺乏并能产生胎盘外松弛素等。由于血浆中孕酮浓度无法反映黄体功能和孕酮的新陈代谢，因此，犬的妊娠调节机制尚未完全探明。对在犬妊娠期发挥主要作用的激素及其对内分泌的影响等相关研究现状进行了综述，旨在为阐明犬的妊娠期内分泌调控机制提供理论基础。

The reproductive mechanism of canine is different from other animals. Its main characteristics include:the maturation of oocytes after ovulation, a delay in the implantation of embryo, rise of serum progesterone concentration before ovulation, similar concentration of serum progesterone between pregnant canine and non-pregnant canine, absence of pregnancy-specific proteins and production of placental external relaxin, etc. Because the progesterone concentration in blood plasma couldn′t reflect the function of luteum and the metabolism of progesterone, so the adjustment mechanism of canine pregnancy was not yet elucidated. The current situations of the relevant research on hormones that played main functions in the gestation period of canine and their effects on the endocrine were reviewed, so as to provide theoretical foundation for enucleating the regulation mechanism of endocrine in the gestation period of canine.
