I don't know if anyone else responded, but here is what I know. I never tried the OV watch, but have heard good things. About the at home semen thing, I say pass. Even if you don't have insurance, your doc can order one for less than 100 and it is better because the at-home versions only show if his friends are there. The test the doctor does will tell you how many, if they seem motile and healthy. It's the better deal in the long run!
