States with laws that require minors to get parental consent before an abortion are making a positive impact on the abortion rate, the Family Research Council says.

A study by the group released Thursday revealed that when a state adopts a parental involvement law, the average abortion rate drops almost 14 percent.

"More protective parental involvement laws result in even larger declines in abortion rates," Michael New, the study's author said. "Furthermore, laws that mandate the involvement of two parents, instead of just one parent, reduce the in-state abortion rate by approximately 31 percent."

The FRC gathered U.S. statistics from 1985 to 1999 to make their analysis.

The family rights groups says Minnesota and Mississippi were two of the most effecting in lowering abortion rates among minors.

"The overwhelming evidence in support of parental involvement laws should be a boon to legislators everywhere," New claimed.

Currently, 36 states have some type of parental consent requirement for those under 18.
