Abstract
An embryo transfer syringe has a roller (30) coupled with the rear end of its plunger (15). The roller (30) is displaceable along an elongate housing (20) extending from the rear of the barrel (10) of the syringe. The roller (30) can be manually engaged through a slot (23) along the housing (20) to rotate it and roll it along the housing thereby smoothly and controllably displacing the plunger (15).
