Abstract

Embryoscopy is a new technique for direct visualization of the first-trimester conceptus. A rigid fiberoptic endoscope is passed transcervically under ultrasonographic guidance into the chorionic cavity. Anatomic scrutiny and direct access to the developing embryo are made possible by this technique.
