title: A-nor steroids as post-coital contraceptives in the hamster with special reference to the transport and degeneration of eggs.
abstract: Two A-nor steroids, Anordrin and H241, showed a marked antifertility effect when given orally to hamsters at 10 mg/kg/day for three or four days after mating. Further study indicated that the antifertility effect was due to a disturbance of egg transport, retarded development and degeneration of fertilized eggs.
