A sperm check is accurate if it is because the patient does not have enough sperm on his or her own; if it is because the test was performed without obtaining a full sample, then this can affect the accuracy of the results. Sperm test includes several items, usually one of the important items in the routine sperm test is the semen volume as well as the sperm count. By having their entire sample tested, their entire sperm count can be assessed. If the sperm count drops, it can affect fertility and lead to infertility, among other things. If the lack of semen volume is due to the patient’s own sperm count, the test results are usually accurate. However, if only part of the patient’s sample is obtained during the test, the quality of the sperm cannot be fully assessed, which may result in an error between the test result and the actual situation. The patient should stop sexual intercourse for 4-7 days before semen retention. Medications such as testosterone propionate and testosterone phenylacetate should not be used 1 week before the test to avoid affecting the accuracy of the results.
