Post-ejaculation urinalysis is a physical, chemical and microscopic examination of the urine after ejaculation. This test is usually done in case there is a low volume of semen due to retrograde ejaculation. Retrograde ejaculation is a form of male infertility where the semen flows back into the bladder instead of flowing out through the urethra at the time of ejaculation. In this case, the semen mixes with the urine and is expelled as waste.

When is recommended?

This test is recommended to male patients who have been facing problems in conceiving. The doctor may recommend a sperm analysis prior to taking this test. A problem in sperm analysis such as low sperm concentration could be due to retrograde ejaculation. PEU is used to confirm the presence of sperm in the urine.

Why is it important?

This test is taken to diagnose retrograde ejaculation which is a very serious problem and a cause of male infertility. A patient is unlikely to overcome this problem. However, in a few cases clinical pregnancy is still possible. Also, a diagnosis could help the doctor offer appropriate medications and possible treatments that could mitigate problem and even bring back normal ejaculation.

How is it done?

The test is done by collecting a sample of the urine taken following ejaculation. After collecting the sample a physical analysis is conducted by expert technicians. The sample is then placed under a microscope to examine its cells and identify the presence of sperm. Also, a special stick is used to examine its chemical appearance.

What do the results mean?

If the patient is affected by retrograde ejaculation, then a large number of sperm cells will be present in the urine. This could be treated by appropriate medications and medical therapies. Also, sperm may be taken directly from the testis and used for procedures like IVF, etc which may help the couple have a baby.

In case the urine does not contain sperm, there could be other reasons causing low semen volume and sperm concentration.
