“Detecting DOR is not difficult,” says Dr. Gleicher,…
European Nations Fall Behind US in IVF Pregnancy Rates
February 6, 2012 (New York, NY) – Recent reports of plateauing IVF pregnancy rates in Europe are in stark contrast to still-rising rates in the US, according to Norbert Gleicher, M.D., a prominent fertility expert and Medical Director of the Center for Human Reproduction (CHR) in New York City. Behind this difference may be a fundamental difference in approaches to the patient-physician relationship in Europe and the US.

Lower IVF Success Rates Widely Reported in Patients of African Origin
May 3, 2011 (New York, NY) – In vitro fertilization (IVF) pregnancy rates, also known as “IVF success rates” are related to specific genotypes and races/ethnicities, according to new research conducted by a New York City-based IVF center. It has long been known that IVF success rates (http://www.centerforhumanreprod.com/ivf-success-rates.html) differ amongst different races/ethnic groups. This new study suggests that predisposition to autoimmune disease (http://www.centerforhumanreprod.com/autoimmune_disease.html) may be the cause for these differences.
