OKLAHOMA CITY (AP) - The state lawmaker who introduced a bill intended to reduce abortions in Oklahoma believes the law will withstand a legal challenge.

The Center for Reproductive Rights has filed a lawsuit challenging the law. It requires a woman to have an ultrasound and get a description of it from the doctor before getting an abortion.

Republican state Senator Todd Lamb says supporters of the law hope that it will reduce abortions in the state. He says he introduced it to encourage life in society.

Lawmakers overrode Gov. Brad Henry's veto to pass the law.

The lawsuit was filed on behalf of Nova Health Systems doing business as Reproductive Services in Tulsa.

It contends the law intrudes on privacy, endangers health and assaults dignity.
