Rebecca Griffin, a mother of 3 boys and a girl, didn't want to wait 20 weeks for a sonogram to find out the sex of her baby. Working with another Texas mom, she developed an inexpensive, home-based test that could predict gender. 

Working with a chemist, she began testing her product, and in November 2006, Intelligender Gender Prediction Test was born.

Available in the family planning section at many pharmacies for $29.99, the test can be used as early as the 10th week of pregnancy.

It works by testing the urine of pregnant women for gender-specific hormones. A color appears to represent a boy or girl. The product is 82% accurate when used in the home, and laboratory results are over 90% accurate.
