Abstract
Starting on the 11th day, the decidua capsularis and trophoblastic giant cell layer disappear from the ends of the conceptus toward the middle. The disappearance is complete antimesometrially on the 18th day, but lateral remnants are still present on the 19th day. New uterine lumen never intervenes between undegenerate decidua capsularis and the uterine stroma. Reichert''s membrane is intact on the 16th day but has ruptured on the 17th. Its apparent disappearance in earlier histological material is an artifact reflecting the weakening that leads to its rupture.
