100 x 106 | This is the mathematical abbreviation indicating the initial number multiplied by 10 to the power of the superscript number, so in this particular instance it is 100 to the power of 6, or 100 to the power of 10 x 10 x 10 x 10 x 10 x 10, or in other words 1 million. One billion is written 100 x 109 (at least in North America - there are some variances in other parts of the world). |
PMMNS | Progressively motile, morphologically normal sperm |
Progressive motility | Progressively motility refers to sperm that are moving forwards in a [close to] straight line. This differentiates from sperm that are merely motile, which are moving but may be traveling backwards, sideways or in circles rather than solely forwards. |
