It is with a heavy heart that we announce the passing of Dr. Jan Friberg, MD, PhD. He was born in Kartineholm, Sweden in 1943 to Carl and Helga Friberg.

As one of the early pioneers of the infertility field, Jan Friberg began his work in Uppsala, Sweden in the 1960s. He began working with Dr. Carl Gemzell, and together, they were the first to extract human gonadotropins from the pituitary glands which later came to be the first Pergonal used for infertility treatments. In 1969 he married the love of his life, Dr. Inger Friberg. In 1975 when Dr. Gemzell moved to New York, Dr. Friberg and his family moved there as well. He completed his residency and his fellowship at Downstate Medical Center in Brooklyn, New York.

In 1981, he and his family moved to Chicago, where he helped start an IVF program in the Midwest. He invented the Friberg Test for sperm antibodies. He also invented the Transcervical Balloon Tuboplasty. Throughout the 1980s and 1990s lectured internationally and held over 130 presentations and published over 160 articles. Between 1983 and 1989, he was Editor in Chief of the Journal of In Vitro Fertilization and Embryo Transfer. He was an Editorial Board Member of the American Journal of Reproductive Immunology from 1982 to 1989.

In 1989, he started his private practice, where he helped countless family achieve their dreams of family building. He continued to treat patients in his private practice up until his passing. In his later years, his interest had focused on the use of stem cells for treatment of infertility.
