About this symptom
Semen analysis measures several characteristics of semen and sperm, including count, concentration, movement and shape. An abnormal value is a finding, not by itself a diagnosis of infertility.
What to know
Results vary with collection conditions, the abstinence interval, recent fever or illness, medicines and laboratory factors. Reference intervals are useful, but no single measurement describes a couple’s chance of conceiving. A specialist interprets the report alongside reproductive history.
Symptoms and reasons for assessment
Common reasons for assessment are a reduced sperm concentration or total count, decreased motility, unusual morphology, differing results from separate samples or difficulty conceiving as a couple. These laboratory findings may occur without physical symptoms.
Other possible causes
Semen abnormalities and erectile difficulties are separate clinical questions, though they may coexist. A normal semen analysis also cannot guarantee conception. The history of both partners and the duration of attempts matter.
How clinicians assess the problem
An andrologist checks how the sample was collected, reviews the report and considers repeating semen analysis after an appropriate interval. Examination and selected hormonal, genetic or imaging tests may be useful if the findings warrant them; these tests are not routine for everyone.
Treatment and follow-up options
Any plan depends on the underlying cause, repeat findings and the couple’s reproductive goals. Avoid starting testosterone, other hormones or fertility supplements without medical advice; some hormonal treatments can suppress sperm production.
When urgent care is necessary
An altered semen analysis alone is usually not an emergency. Sudden severe testicular pain, swelling of the scrotum or a high fever needs urgent assessment because another condition may be present. For a medical emergency call 103.

Frequently asked questions
Does one poor semen analysis mean I am infertile?
No. Individual semen parameters do not establish or exclude male infertility without considering the wider clinical and reproductive picture.
Should semen analysis be repeated?
Often, yes, if the first report is abnormal. A specialist will advise on preparation and timing in your particular situation.
Who should interpret these results?
An andrologist or another appropriately qualified clinician relates the laboratory findings to examination, medical history and the couple’s plans.
Important information
A medical consultation is needed for diagnosis and treatment recommendations.
Self-treatment can be harmful to your health.
