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.
- 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.
