This utility model relates to the field of assisted reproductive technology, specifically to an embryo transfer tube, comprising a first tube segment and a second tube segment connected to each other. The inner diameter of the second tube segment is larger than that of the first tube segment. A piece of absorbent cotton is placed inside the second tube segment. An annular limiting seat is provided on the inner wall of the second tube segment at the end away from the first tube segment, and the inner diameter of the annular limiting seat is smaller than that of the second tube segment. By setting an annular limiting seat at the end of the larger-diameter second tube segment, this utility model can reduce the air intake cross-sectional area, increase airflow resistance, and make the negative pressure generated by the suction bulb more gradual. This facilitates the operator's precise control of the embryo aspiration position, thereby reducing the risk of embryos being accidentally aspirated into the second tube segment. Simultaneously, the absorbent cotton placed inside the second tube segment further intercepts any embryos and fluids that may be accidentally aspirated.
