Karen Christine Baker

Associate Professor of Urology
40 Duke Medicine Circle, Clinic 1G, Durham, NC 27710


I am a Urologist with fellowship training in male fertility and microsurgery. I utilize surgical, medical, and lifestyle interventions in my practice and I work hand-in-hand with our female reproductive specialists to help couples reach their goal of having a baby.  I arrived at Duke after serving 24 years in the Army as a Urologist and male fertility specialist. During my time in the Army I was a Primary or Associate Investigator for over 30 industry sponsored or investigator initiated clinical and basic science trials.
There is much we do not know about infertility in general and male infertility in particular.  My research interests include quantifying the impact of common medical conditions on male fertility and investigating their pathogenic effects on spermatogenesis and sperm function,  delineating the impact of male factor infertility on outcomes of assisted reproductive techniques, and investigating the efficacy of medical therapy for male factor infertility.  I am also interested in the social, psychological and health impacts of infertility.
