Welcome to The Visible Embryo, a comprehensive educational resource on human development from conception to birth.

The Visible Embryo provides visual references for changes in fetal development throughout pregnancy and can be navigated via fetal development or maternal changes.

The National Institutes of Child Health and Human Development awarded Phase I and Phase II Small Business Innovative Research Grants to develop The Visible Embryo. Initally designed to evaluate the internet as a teaching tool for first year medical students, The Visible Embryo is linked to over 600 educational institutions and is viewed by more than ' million visitors each month.


WHO International Clinical Trials Registry Platform
The World Health Organization (WHO) has created a new Web site to help researchers, doctors and patients obtain reliable information on high-quality clinical trials. Now you can go to one website and search all registers to identify clinical trial research underway around the world!

Celiac Disease May Explain Some Women's Infertility
A recent study found increased rates of celiac disease in women who present with unexplained infertility.

WHO Child Growth Charts

A recent study demonstrated increased rates of celiac disease in women who present with unexplained infertility.

Published in the May-June 2011 issue of The Journal of Reproductive Medicine, the study evaluated 191 female patients presenting with infertility. Each participant underwent serologic screening for celiac disease as well as routine infertility testing. The 4 patients who had positive serum test results were advised to seek evaluation with a gastroenterologist. All 4 patients were confirmed to have celiac disease. They then underwent nutritional counseling to change over to a gluten-free diet.

Among the 188 patients who completed testing, the prevalence of undiagnosed celiac disease was 2.1%. While this rate was not significantly higher than the expected 1.3%, the diagnosis of celiac disease in women with unexplained infertility was found to be significantly higher at 5.9% (3 of 51 women). Interestingly, all 4 patients found to have celiac disease conceived within a year of diagnosis.

Though the study numbers are small, the findings suggest that, at least for some women with infertility, dietary measures may help bolster fertility.

"Diagnosing celiac disease in an infertile woman would be particularly beneficial if the low-cost (and low-risk) therapy of pursuing a gluten-free diet could improve chances for conception," says lead author Janet Choi, MD, a reproductive endocrinologist at the Center for Women's Reproductive Care at Columbia University.

Co-author Dr. Peter Green, director of the Celiac Disease Center at Columbia University Medical Center, adds that these results should be added to the increasing body of knowledge concerning the impact of undiagnosed celiac disease on women's reproductive health.

Celiac Disease Center at Columbia University Medical Center provides comprehensive medical care for adults and pediatric patients with celiac disease, including nutrition and attention to the multiple associated conditions that occur in celiac disease. The Center is involved in the care of thousands of patients with celiac disease and gluten intolerance, providing better access to proper testing, diagnosis, treatment and follow-up care.
