Ovulation detector. Does it work on humans?
Wow, good question Mike, I don't know, it does not go by temp, but the chemical state at the peak.
I know my wife wanted a boy, and she was doing temps checks, and creating a chart, when the next month came we had this window to make a boy, oh crap I was dragging my ass to work.
My boss said are you OK, you look so beat, damn he was a coolest best boss I ever had, I told him what was going on, he said, go home, you got work to do.
It did work both my brother, and sister had two girls each, right after our son was born they both had one more girl, so it's not luck, it's planning.
My best buddy I know sells these, he speaks Polish-born here, nicest person I know. he has an exclusive deal to sell this here, its worth it, even the Amish, have found him, and buy it, I guess if they get high tech, it must be worth it, beats having two baby pigs born VS 10 if you time it right, so for any
real breeder, it pays for its self on the first use.
