Cedar Rapids television station KCRG reports that the merger was announced Thursday and will occur next year.
Vanessa Solesbee is board chairwoman of Planned Parenthood of East Central Iowa. She says the group's clinics in Cedar Rapids and Dubuque will remain.
The president of the Des Moines group, Jill June, says there is no plan to offer adoption, abortions or other new services immediately. Abortions and adoption services are not currently provided at either the Cedar Rapids or Dubuque clinics.
Solesbee and June say the merger will allow more efficiencies in purchasing and technology.
