Arguably, sperm cells displaying a distal cytoplasmic droplet or abaxial tails are not normal; however, the presence of very high proportions of either of these aberrations has not been shown to negatively impact fertility. Distal droplets are shed after a period of exposure to vesicular fluid and will often be seen as tiny white circular structures on the smear (Figure 9.3). If there are no other defects visible, sperm displaying a distal droplet or an abaxial tail should be counted as normal (Table 9.3).
