Key facts

Spermatozoa Motile [#] in Semen --post ejaculate

Spermatozoa.motile^post ejaculate

Semen quality is expressed as total motile sperm count (VCM)volume (mL) x sperm concentration (10^6/mL) x percentage forward motility. World Health Organization (WHO) guidelines for determining semen quality are as follows: normal= >40 x 10^6, moderate= 20-40 x 10^6, and poor= <20 x 10^6. Causes for decreased total motile sperm count may be medical (i.e. testicular cancer, infections, hormone imbalances, medications), environmental (i.e. pesticides, exposure to heavy metals or radiation), or lifestyle-related (i.e. alcohol abuse, smoking, age, stress).
