Sperm Morphology (Shape) Sperm shape is an important predictive indicator of sperm fertilising ability. Compared with other species, the human has a relatively small percentage of sperm showing a ‘normal’ morphology (actually defined as being ideally shaped), with as few as 15% normal forms being regarded as the lower limit of normal.
