To Test a woman: The 5 Minute Semen Detection Test kit really works! If semen stains are present in her underwear, there is only one way they got there.

After a woman has sexual intercourse she experiences what is referred to as "Flowback". This "Flowback" causes a woman to have dried and/or invisible traces of dried semen in her underwear long after a sexual encounter. Typically, a woman will continue to secrete small amounts of semen for up to 72 hours after sex. Even after a shower. The test is scientifically formulated to detect a certain enzyme that is produced by the male prostate gland. This enzyme is found at very high levels in a mans semen. As long as the article to be tested has not been washed, invisible traces of dried semen will remain present for long periods of time. Up to 2 years or even longer. If any semen is present, even the smallest trace amounts, you will see a purple color appear instantly. There's really no way out of it. The 5 Minute Semen Detection Test kit really works!
