虽然父亲的亲代照顾在哺乳动物中很少见，但在双亲代物种中，父亲的亲代照顾对后代的生存和正常发育至关重要。越来越多的双亲代啮齿动物的研究已经确定了几个发育和经验影响父亲的反应。其中一些因素，如青春期的成熟，与幼崽的互动，以及来自怀孕配偶的暗示，会导致雄性个体一生中父亲反应性的显著变化。其他因素，特别是怀孕期间的宫内位置和出生后发育期间父母的照顾，可以对父亲的行为产生长期影响，并有助于物种内个体之间的稳定差异。以五种已被充分研究的双亲本啮齿类动物为研究对象，我们回顾了影响父本反应性的发育和经验因素，并考虑了它们在产生个体内和个体间变异中的作用。我们也回顾了激素和神经肽已被证明调节父权照顾和讨论他们的潜在贡献内部和男性之间的行为差异。最后，我们讨论了大脑内由性腺类固醇激素调节的抗利尿激素和催产素信号传导可能代表了发育和经验变量对父权照顾个体内和个体间差异的“最终共同途径”。
Parental care by fathers, although rare among mmmals, can be essential for the survival and normal development of offspring in biparental species. A growing body of research on biparental rodents has identified several developmental and experiential influences on paternal responsiveness. Some of these factors, such as pubertal maturation, interactions with pups, and cues from a pregnant mate, contribute to pronounced changes in paternal responsiveness across the course of the lifetime in individual males. Others, particularly intrauterine position during gestation and parental care received during postnatal development, can have long-term effects on paternal behavior and contribute to stable differences among individuals within a species. Focusing on five well-studied, biparental rodent species, we review the developmental and experiential factors that have been shown to influence paternal responsiveness, and consider their roles in generating both intra- and inter-individual variation. We also review hormones and neuropeptides that have been shown to modulate paternal care and discuss their potential contributions to behavioral differences within and between males. Finally, we discuss the possibility that vasopressinergic and possibly oxytocinergic signaling within the brain, modulated by gonadal steroid hormones, may represent the "final common pathway" mediating effects of developmental and experiential variables on intra- and inter-individual variation in paternal care.
