Abstract
Summary
Fourteen rats, hypophysectomized 1 to 5 days after mating, were injected with lactogenic hormone (1 or 3 mg daily). In 4 animals implantation failed to occur. Of the remaining 10 animals 2 carried to term or beyond, while pregnancy was interrupted after 6-17 days in 8 rats. It would seem that lactogenic hormone was capable of stimulating corpus luteum function sufficiently to induce implantation and to maintain pregnancy for periods ranging from 6 days to term or beyond.
