The invention relates to an oocyte-holding pipette for sperm injection methods without cytoplasmic aspiration, comprising an elongate, narrow, hollow, cylindrical body, inside which runs a suction conduit that communicates with a working end in order to hold an oocyte, said working end being flared to form a funnel defining an internal conical cavity, the proximal end of which, of smaller diameter, communicates with the suction conduit and the distal end of which, of larger diameter, is dimensioned to receive the oocyte in a tight-fitting manner, such that, upon aspirating same via the suction conduit, the oocyte remains partially trapped inside and becomes deformed, changing from its spherical shape in the resting state to an oval shape that tensions the surface and increases the turgor.

Oocyte holding pipette for sperm injection procedures without cytoplasmic aspiration that, configured from a long, narrow and hollow cylindrical body, through which a suction conduit runs that communicates with a working end to hold an oocyte, is characterized in that said working end has a bell-shaped funnel-shaped configuration that defines an internal conical cavity, whose proximal end, of smaller diameter, communicates with the suction conduit and whose distal end, with a larger diameter, is dimensioned to tightly receive the oocyte in such a way that, when suction is applied to it through the suction conduit, is partially trapped inside to deform, from its spherical shape in a state of rest, to an oval shape that tightens its surface and increases its turgor.
