Note
- Partial zona dissection, in which a fine cutting pipette is pushed through the zona pellucida and the oocyte is released from the holding pipette and rubbed against the cutting pipette until a slit is produced, was proposed as a method for increasing fertilization. On average, fertilization rates are lower after partial zona dissection (PZD) compared with zona drilling and polyspermy rates are also generally reduced. This is possibly due to the smaller breech of the zona pellucida after PZD (80 µm2) compared with that produced after zona drilling (230 µm2). These techniques demonstrated that fertilization and pregnancies could be achieved with semen of very poor quality, but successes were sporadic. (Source : INRA)
