Sperm detection test

sperm detection

Do you think there is sperm on your clothes or any other medium, but you don't know how to check it? In another measure, do you think your partner could be cheating on you?


A sperm detection test can effectively determine the presence of sperm with 100% certainty, giving you the answer you are looking for. After sending your sample, the results are communicated to you by the laboratory by email in just 10 days.


The sperm detection test is an analysis that can clear up doubts about your partner's infidelity.

What types of media can the laboratory analyze for sperm detection?

The laboratory is capable of analyzing a wide variety of media, such as:

  • Bedding, including sheets, pillows, mattresses, cushion covers, and blankets

  • Any type of clothing or underwear

  • Various objects, including erotic objects

  • Condoms


The seminal fluid detection test does not require a kit. The laboratory just needs your sample: once you have placed your order, you will receive instructions by email to return your samples by mail.


It is extremely important that all samples are handled as little as possible. Please use gloves to prevent any possibility of contamination.

How does the laboratory analyze the sample to detect sperm?

The analysis process is performed in the laboratory to identify the presence of sperm by detecting body fluids. This method seeks to identify specific proteins (semenogelin, a protein produced by the seminal vesicles which is responsible for the clotting of ejaculate) which are unique to sperm, allowing detection up to 1 μL of human sperm.

The sample is treated with specific chemical reagents which react in the presence of this protein. If semenogelin is present in the sample, a reaction will occur, which can confirm the presence of sperm.

It is essential to mention that this method of sperm detection must be performed in a controlled laboratory environment. This not only ensures the accuracy of the results but also avoids any contamination that could distort the results.

The stained item will be damaged during the testing process and will generally not be returned to you. The analyst will cut 2 to 4 square sections of 1 cm from the stained area of the material to be tested.

  • The first step is the screening of prostate acid phosphatase (PAP), an enzyme produced in the male prostate.

  • The second step is the test of the Prostate Specific Antigen (PSA), which is performed only if the PAP screening gives a positive result. PSA is a protein produced by the prostate gland of an adult man.

  • The last step is the visual identification of sperm cells. The chemicals used color different parts of the sperm cell (the head and tail) in different colors. This step allows the detection of the presence of sperm cells, but cannot determine the number, mobility or quality of the sperm cells.

Three-step detection:


The results are extremely concise and simple: the laboratory simply indicates the object tested and whether the presence of sperm has been confirmed or excluded.


The sperm detection test will offer one of the following results:

  • A positive result: in this case, the presence of sperm has been confirmed.

  • A negative result: in this case, the presence of sperm has been excluded.


The results of a sperm detection test have no legal validity.

Are there other tests I can perform?

Following the results of the Sperm detection test, some people choose to take an Infidelity DNA Test to deepen their research. The Infidelity DNA test is not aimed at detecting sperm, but at detecting DNA.


This test allows you to identify the DNA on the sample you provided us for the sperm detection test. Thanks to this analysis, the laboratory can determine the presence of DNA, the number, and the sex: male and / or female.


It is also possible to compare the DNA from your sample with another sample you have provided, called the reference sample (usually a mouth swab sample). By comparing the DNA from these two samples, the analysis can determine whether the DNA belongs to the same person or not.


This last step is only possible if the genetic profile on the sample is complete. Indeed, depending on the type of sample and the method of preservation, the laboratory may not be able to establish a clear profile for comparison.


Note: The laboratory can test a variety of samples for the presence of sperm. This test does not require a kit. Once your order is confirmed, you will receive an email with instructions for returning your sample. Make sure to put the sample to be tested in a paper envelope. However, before sending the sample, it is necessary to locate the stained area, cut it out or mark it, and pack it for shipment to the laboratory.
