Makers of the "morning after" pill now want to give minors easy access to the controversial drug.
Less than two years ago, the Food and Drug Administration gave the okay for Plan B to be purchased over-the-counter by adults.
Now, Teva Pharmaceuticals is seeking approval to lift the FDA rule that requires those under age 17 to have a prescription for the drug.
Plan B -- a well-known emergency contraception pill -- is seen by many pro-lifers as an abortion drug.
"We believe it is important that we remove all the barriers to obtaining 'Plan B One-Step' so that anyone who needs it can get it as quickly as possible," Teva spokeswoman Denise Bradley said.
Pro-life groups want the age restriction to stay in place so a doctor can be involved in a possible pregnancy involving a minor.
"Parents should be very concerned that the FDA and the drug company are trying to sell this drug to minor girls without the parent's knowledge or consent," Concerned Women for America President Wendy Wright told Fox News.
Teva leaders say Plan B must be taken within three days of unprotected sex to be effective, and by the time a minor sees a doctor it may be too late for them to acquire the drug if they wanted to.
