: What This Test Measures
: A semen analysis looks at several features of a semen sample, including the number of sperm (count), how well they move (motility), their shape (morphology), the volume of semen, and its consistency. Together these features help show how healthy the sperm and semen appear.
: Why It Is Done
: This test is commonly ordered when a couple is having trouble getting pregnant, to help find possible causes. It may also be done before certain fertility treatments or after procedures that could affect fertility. It is a routine first step in evaluating male fertility.
: How the Sample Is Collected
: The sample is usually collected privately at the clinic or laboratory, or sometimes at home and delivered promptly. It is collected into a sterile container, and you will be given specific instructions about timing and handling. Following those instructions carefully helps ensure the most accurate results.
: What Results Mean
: Results describe sperm count, movement, shape, and semen volume and are usually compared against general reference ranges. A single result outside a range does not automatically mean infertility, because values can vary between samples and over time. Your clinician will interpret your results along with your history and may repeat the test.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
: A semen analysis helps assess male fertility and can point to possible causes of difficulty conceiving. Abnormal findings may relate to sperm production, hormone issues, blockage, or other factors, and often lead to further evaluation. Because results can vary, repeat testing and clinical context are important.
