What is the Semen Analysis?

A semen analysis can help clarify whether a man has a reproductive issue that is causing infertility, if a vasectomy has been successful, and if the reversal of a vasectomy has been successful.

A semen sample will be examined for:

  • Volume. This is a measure of how much semen is present in one ejaculation.
  • Liquefaction time. Semen is a thick gel at the time of ejaculation and normally becomes liquid within 20 minutes after ejaculation. Liquefaction time is a measure of the time it takes for the semen to liquefy.
  • Sperm count. This is a count of the number of sperm present per milliliter (mL) of semen in one ejaculation.
  • Sperm morphology. This is a measure of the percentage of sperm that have a normal shape.
  • Sperm motility. This is a measure of the percentage of sperm that can move forward normally. The number of sperm that show normal forward movement in a certain amount of semen can also be measured (motile density).
  • pH. This is a measure of the acidity (low pH) or alkalinity (high pH) of the semen.
  • White blood cell count. White blood cells are not normally present in semen.
  • Fructose level. This is a measure of the amount of a sugar called fructose in the semen. The fructose provides energy for the sperm.

How is the Semen Analysis performed?

If a low sperm count or a high percentage of sperm abnormalities are found, our fertility experts will recommend further testing. Other tests may include measuring hormones, such as testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), or prolactin. A small sample (biopsy) of the testicles may be needed for further evaluation if the sperm count or motility is extremely low.
