That's completely correct. The average ranges from 40 million per mL to 300 million per mL[1]. Actual infertility has to have quite a few markers before it's likely - according to this[2] one measure was a count lower then 13.5 million/mL, motility less then 32 percent and less then 9 percent normal morphology. Cutting a low sperm count by 50%, but with no degradation of motility or morphology for example, is quite likely not to make you infertile at all (remembering too: people who don't have trouble conceiving don't seek sperm analysis).
