Semen Analysis (WHO Criteria)

Semen Analysis is used to evaluate the semen produced by a man which is a determinant factor for male fertility. It is used to measure the amount of semen produced, the quality and quantity of sperm in the sample. Abnormal Semen / Sperm accounts for one third of all infertility problems.

Semen-AnalysisSemen Analysis is performed to check the following

  • Volume of semen in each ejaculation
  • Time taken by the semen to liquefy or liquefaction time
  • Number of sperm present per milliliter (ml) of semen in one ejaculation or the Sperm Count
  • Sperm morphology
  • Sperm Motility
  • ph of the semen
  • presence of white blood cells
  • fructose level in the semen

Semen Analysis is done to determine infertility problems, or to determine the success of vasectomy or its reversal.

Semen sample needs to be evaluated within 1-2 hours of ejaculation to provide accurate results. Further evaluation may be needed if the semen analysis results yield low sperm count or high sperm abnormalities.
