Check Mate is a DIY semen detection kit being marketed to people living with the "nightmare of suspicion and doubt caused by the infidelity of a cheating spouse or of a sexually active teen." The kit differs from those black light detection kits we see on CSI. It actually looks more like a home insemination kit, since it comes with two turkey basters. It seems like there is tons of room for error with this kit, as it relies on the idea that the woman being tested has had unprotected sex, and the man being tested hasn't jerked off in days.
