In 304 female beagles exposed at puberty to either 100 or 300 r x rays (250 Kv; 30 ma) and 57 controls, the rhythmtc recurrence of estrus remained normal until the dogs one-half of the dogs whelped two litters; the irradiated groups equaled or bettered the controls. Another colony consisting of 11 controls and 7 x-irradiated (300 r) dogs were bred on each estrous period and demonstrated that irradiated dogs maintain fertility following successive matings. These experiments suggest that, until the advent of senility, dogs receiving x- ray exposures up to a median lethal dose are not affected in their reproductive capability. A limited number of beagles surviving a median lethal dose of fast neutrons (E max of 12 Mev) were fertile, but unable to whelp or lactate during the first 2 years after exposure, after which reproduction was normal.
