Semen Analysis

Semen analysis is the first diagnostic test done in order to evaluate male fertility. Standard

semen analysis measures three main parameters – sperm concentration (in million per ml), sperm motility (in percentage) and sperm morphology (again in percentage). The criteria of the World Health Organization (WHO) and Kruger’s strict criteria for sperm morphology are used in determining the diagnosis. The results come out in about one and a half hours.

As well as the measurement of those three main parameters, extended semen analysis also includes processing of the semen sample through density gradient centrifugation in order to evaluate the quality of the sperm after it was run through a gradient. This type of processing is routinely done prior to a procedure of intrauterine insemination or in vitro fertilization in order to select the best spermatozoa for the assisted reproductive procedure. The results come out in 24 hours.
