Abstract
An embryo transfer syringe has a roller coupled with the rear end of its plunger. The roller is displaceable along an elongate housing extending from the rear of the barrel of the syringe. The roller can be manually engaged through a slot along the housing to rotate it and roll it along the housing thereby smoothly and controllably displacing the plunger.
