Have you noticed a change in your relationship?

Does she make excuses for where she has been?
Has she lost interest in the physical aspect of your relationship?

There are two primary techniques that can be utilized to characterize suspicious stains, semen screening and DNA testing.
During and after sexual activity, semen, containing up to 300 million sperm, can be deposited on undergarments, panties, bed sheets, clothing, upholstery or other surfaces. Sperm can last as long as 3–5 days in the vagina and remain identifiable for years as dried stains.
