The total number of normal, motile sperm in an ejaculation can be used to assess a man's fertility.
total motile functional sperm =
= (volume in mL) * (sperm density) * (per cent motile) * (per cent normal morphology)
Interpretation:
• The normal is > 40,000,000 per mL
Infertile males may show:
(1) reduced volume (< 3 mL)
(2) reduced motility (< 25%)
(3) reduced numbers (< 20,000,000 sperm per mL); however, count alone is not a determinant, since males may be fertile with low counts
