A class-action lawsuit has been filed against the maker of a controversial baby gender test, NewsChannel5 reported.

Many expecting couples put their trust in Acu-Gen's new baby gender monitor test and received the wrong results.

The test claims its 99.9 percent accurate and offered a money-back guarantee.

Sixteen women who are part of the class-action lawsuit claim the results were wrong and their money was not refunded.

NewsChannel5 featured the gender test as part of a special assignment on Sunday.
