What is this test?
This qualitative test uses microscopy to examine a semen sample for the presence of sperm. It reports whether sperm were identified rather than providing a sperm count.
Why might I need this test?
It may be used during a fertility evaluation or as part of a broader assessment of the male reproductive system. It can also help confirm that a submitted specimen is semen.
How is the test performed?
A fresh semen specimen is collected in a sterile container and examined under a microscope. The laboratory looks for sperm and records a qualitative result.
How do I prepare for the test?
Follow the laboratory's instructions about collection and timing, including any recommended period of abstinence. The complete sample should be collected in the laboratory-provided container and kept at the temperature specified by the laboratory.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
If sperm are identified, the result confirms that they were present in the submitted sample at the time of examination. If none are found, possible explanations include a collection or laboratory-handling problem, recent ejaculation, or a condition associated with an absence of sperm in semen.
Short name
Sperm presence, semen
