Dr. Richard Paulson is the Director of USC Fertility, and has been with the practice since 1986. He is also a Professor of Obstetrics and Gynecology and Chief of the Division of Reproductive Endocrinology and Infertility at the University of Southern California Keck School of Medicine.

Dr. Paulson has been rated one of “The Best Doctors in America” continuously since 1994. He has published several landmark investigations addressing the effect of age upon female fertility, including the first observation that egg donation could be used to extend the reproductive lifespan in women over 40. Dr. Paulson’s work has extended to fertility in women over the age of 50 and, in 1997, he reported a successful pregnancy in the oldest woman on record at the time, aged 63.
