Sperm property
WHO standard for normal sperm property
Sperm count
10 million sperms per milliliter.
Sperm morphology
Head: oval in shape, 3–5 μm long and 2-3 μm wide Middle piece: less than 1 μm in width, 5–7.5 long, and must be uniform and visible Tail: 45 μm in length, uniform, and visible
Sperm motility
Fast progressive: velocity more than 25 μm/s Slow progressive: velocity less than 25 μm/s Immotile: velocity is equal to zero
