Not insane. This is true. Iirc, there's some hormonal changes in the urine that causes the wheat/barley to grow first, depending on the sex of the fetus.
The accuracy of this method is overexaggerated, though. Iirc, when tested, it was found to be something like 75% accurate. For what it's worth, that's pretty accurate for the ancient world
You can think the concept of ancient Egyptian sonar isn't insane if you like, but the Egyptians didn't have sonar because it was developed in 1915 and you don't use sonar to look at a baby in the womb, you use ultrasound. Sonar uses sound within the range of human hearing.
Also, it isn't true.
