A semen analysis, also known as a sperm count, is a lab test that measures the quality and quantity of sperm in a man's semen. It's one of the first tests performed to evaluate male fertility.
The test involves:
Providing a sample: You provide a semen sample and get it to the lab within 30 minutes.
Analysis: A lab specialist examines the sample under a microscope to evaluate the following:
Volume: The amount of semen in the sample
Sperm count: The number of sperm in the sample
Sperm concentration: How close together the sperm are
Sperm movement: The percentage of sperm that are moving forward
Sperm shape: The number of sperm that have a normal shape
pH: The acidity of the semen
White blood cells: The presence of white blood cells in the sperm may indicate an infection
To get the best sample, you should:
Avoid sexual activity for 2 to 3 days before the test, but no longer than 5 days.
Stop taking herbal medications like St. John's wort and echinacea.
Avoid hormone medications as instructed by your healthcare provider.
Abnormal results on a semen analysis could indicate infertility, infection, hormonal imbalance, disease, gene defects, or exposure to radiation.
