Frequently Asked Questions

What is the SemenSPY Semen Detection Kit?

The SemenSPY Semen Detection Kit is an easy to use revolutionary way to reveal sexual infidelity by detecting traces of seminal fluids that are left behind on items such as undergarments, bed sheets, clothing, upholstery or other surfaces.

How does it work?

The SemenSPY Semen Detection Kit is designed to detect semen that is produced by the male prostate gland using the most accurate method available on the market today: PSA

What if the material is white and I can't see a stain?

Our Deluxe Edition includes our SemenSPY UV Light that aids to uncover and identify even completely invisible traces of semen that may be locked into the fibers of the suspected article/s. SemenSPY® works on any type or color of material.

What if there is a stain and I am not sure if it is semen?

Our SemenSPY Semen Detection Kit was designed to only test positive for the presence of semen. All other bodily fluids will test negative. Our SemenSPY UV Light will pick up traces of many bodily fluids and was designed as an aid to assist in finding bodily fluids that may be invisible to the naked eye. (Deluxe Edition Only)

Will the test stain or damage the article being tested?

No, the test will not stain any article/s being tested regardless of the method chosen. There are two testing methods that can be conducted during the process. The destructive method will cause damage where as the non destructive method will not.

Is this an accurate test?

SemenSpy is extremely accurate and effective. If any traces of semen are present on the area you decide to test, SemenSPY® Semen Detection Test will detect it.

How long can semen stains remain present?

Semen stains can remain present for very long periods of time. Though most people are only concerned with testing items that are thought to have recently been soiled with semen traces, laboratory tests have revealed traces of semen on articles over 30+ years old, as long as the article has not been washed of course.

What if the male subject had a vasectomy?

Semen and Sperm are two completely different things. A vasectomy eliminates only sperm while semen production remains.

I'm a male and I want to test a female. Will I detect myself?

No, but you must abstain from having intercourse with the female you want to test for a period of time so your seminal fluid will not be detected. Remember, the current conditions and circumstances of the relationship that have led to purchasing and use of the SemenSPY® test kit. At this point the relationship in question is usually not engaging in regular sexual activity together anyway so this is typically not an issue.

Will this test kit work if the woman or man uses a condom?

Condoms are designed to keep semen out. People also use condoms much less frequently than the media wants you to believe. Think about anytime you have had sex using a condom to know that the chances of semen being present after sex are excellent due to a term called "outercourse". Usually the first thing a male does after having intercourse using a condom is remove it. At that time there is usually some time of affection or activity that takes place and usually the male is lying on top of the female at some point. It is during this "outercourse" that semen is deposited onto the woman's body.

Can I test any article for semen? Like a seat in a car or a sofa?

Absolutely. SemenSPY was designed specifically for the home user and does not stain any article being tested.

    caught a cheater

    helped me catch a cheater, the light is awesome...removed one star because you kind of have to catch the stains before too much time goes by (like dont wait weeks or months)
