Research Summary

Dr. Van Voorhis' research focuses on evaluation and treatment of the infertile couple. He is interested in outcomes research including cost-effectiveness studies. He has published on birth defects following in vitro fertilization which appear to be slightly increased by this treatment. He is currently exploring the possible mechanisms of this finding. In addition, he is interested in reducing complications from infertility treatment, including reducing the rates of multiple gestations. Other areas of interest include novel ovulation induction techniques and evaluation of benign uterine conditions including endometrial polyps and fibroids and their effect on fertility.
