About 50% of sexually-naive male CF-1 mice (Mus musculus) commit infanticide (kill young). But, 80-90% of male mice commit infanticide between 1-4 days after mating. Between 12 and 50 days after mating infanticide is inhibited and most males (80-100%) behave parentally toward young (they build a nest, retrieve and groom the young, and hover over the young to keep them warm). Beginning at 60 days after mating, infanticide is again facilitated and parental behavior is inhibited (70-80% of males commit infanticide). The facilitation and inhibition of infanticide as a function of time after mating is mediated by the act of ejaculating rather than by mounting and intromitting during mating or by cohabiting with a female either before or after mating. The experience of committing infanticide either prior to mating or within the first 4 days after mating does not influence the facilitation of parental behavior that occurs 12 days after mating. But, repeated contact with young after males become parental serves to maintain parental behavior for an extended period of time. The age of the young (newborn-20 days old) utilized as stimulus animals does not influence these time-dependent changes in the behavior of male mice after ejaculation. This phenomenon is unique in that a response (infanticide) to a novel stimulus (young) is facilitated, then inhibited, and then facilitated again as a function of time between an event (ejaculation) and exposure to the novel stimulus.(ABSTRACT TRUNCATED AT 250 WORDS)
约50%未经性经验的雄性CF-1小鼠（小家鼠）会实施杀婴行为（杀死幼崽）。但是，80 - 90%的雄性小鼠在交配后1 - 4天会实施杀婴行为。在交配后12至50天，杀婴行为受到抑制，大多数雄性（80 - 100%）对幼崽表现出亲代行为（它们筑巢、找回并照料幼崽，在幼崽上方盘旋为其保暖）。从交配后60天开始，杀婴行为再次变得容易发生，亲代行为受到抑制（70 - 80%的雄性实施杀婴行为）。交配后杀婴行为的促进和抑制是由射精行为介导的，而非交配期间的爬上和插入行为，也不是交配前后与雌性同居。在交配前或交配后前4天实施杀婴行为的经历，不会影响交配后12天出现的亲代行为促进。但是，雄性小鼠变得具有亲代行为后，与幼崽的反复接触有助于长时间维持亲代行为。用作刺激动物的幼崽年龄（新生至20日龄）不会影响雄性小鼠射精后这些随时间变化的行为。这种现象很独特，因为对新刺激（幼崽）的反应（杀婴行为）先是促进，然后抑制，接着又随着事件（射精）与接触新刺激之间的时间变化再次促进。（摘要截选至250词）
