BERLIN (AP) -- Organ donations have dropped sharply in Germany following a scandal over alleged corruption at several transplant clinics.

The German Foundation for Organ Transplantation says the number of organs donated fell almost 13 percent to 3,917 last year, the lowest figure in a decade.

Several German clinics are being investigated over allegations that doctors manipulated waiting lists to help some patients appear sicker than they were and so receive transplants sooner.

The foundation said Monday that the scandal had "massively shaken" the public's faith in the transplant system.

Some 12,000 people in Germany require organ transplants each year.
