Test for Sperm Motility and Morphology (Quantitative Analysis of Sperm Parameters)
This test evaluates the health and function of sperm cells, including their movement and shape, which are important for fertility.

What This Test Measures
Your sample will be analyzed to measure two key aspects of sperm: motility (movement) and morphology (shape). Motility is typically evaluated for forward progression and overall activity, while morphology assesses the structural integrity of individual sperm cells. Advanced techniques may also include quantitative assessments of specific sperm characteristics, such as concentration or viability, depending on the lab’s methodology.
Sample Collection and Preparation
This test requires a semen sample collected through masturbation after at least 2–5 days of abstinence. The sample is then processed in the lab to isolate sperm cells for detailed analysis. Some labs may use specific centrifugation or washing techniques to prepare the sample for precise measurement.
Common Uses and Clinical Context
This test is commonly ordered as part of a fertility evaluation for both men and couples struggling with conception. It helps identify issues like low sperm count, poor motility, or abnormal sperm shape, which may contribute to infertility. It may also be used to monitor treatment responses, such as those from hormone therapy or surgical interventions.
How the Test Works
The test typically involves microscopic examination of sperm under a microscope to count and assess movement (motility) and shape (morphology). Some advanced versions use automated systems to quantify additional parameters, such as sperm concentration or viability, though these may not always be reported in all labs. Results are often expressed as percentages or ratios rather than absolute numbers.
