Paul Niehans

Swiss physician (1882-1971)

Injecting animal cells into the human body formed the basis of the fresh cell therapy developed by Paul Niehans. Born in Bern in 1882, this Swiss physician and surgeon gained international attention throughout the mid-twentieth century for a controversial medical practice that claimed to address ailments ranging from diabetes and cancer to sexual dysfunction.

Early Career and Education

Before establishing his reputation in cellular medicine, Niehans pursued a background in theology prior to shifting his focus to the medical field. He served as a doctor within the Swiss Army starting in 1912 and maintained this role throughout the duration of World War I. His upbringing was grounded in a medical household as the son of a physician.

Development of Fresh Cell Therapy

In 1931, Niehans conducted the initial tests for what he termed his method, later categorized as fresh cell therapy. This practice involved extracting fresh or dried animal cells—typically harvested from bovine or sheep sources—and injecting them into human muscle tissue. Niehans marketed the procedure as a wide-ranging treatment for conditions including heart issues, anemia, and impotence, while also promoting it for cosmetic purposes like breast enhancement.

Scientific Evaluation and Institutional Recognition

Medical experts and organizations have consistently found no objective evidence to support the efficacy of fresh cell therapy for any health condition. A 1963 investigation by the American Cancer Society reported that the treatment yielded no documented benefits. Due to safety concerns and a lack of proven effectiveness, the therapy is not legally available in Switzerland or the United States. Despite the lack of medical consensus, Niehans gained visibility after providing services to Pope Pius XII, which led to his appointment to the Pontifical Academy of Sciences in 1955.
