Embryoscopy is a relatively new and investigational technique that permits direct visualization of the fetus as early as the first trimester. Initially, a rigid fiberoptic endoscope was passed transcervically into the extracoelomic cavity, permitting inspection of fetal anatomic structures; fetal blood sampling was also feasible by this method. However, improvements and advancements in fiberoptic technology have led to the performance of thin-gauge transabdominal and transcervical embryoscopy, allowing visualization as early as 4 weeks after conception.
