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 one million visitors each month.

Today, The Visible Embryo is linked to over 600 educational institutions and is viewed by more than 1 million visitors each month. The field of early embryology has grown to include the identification of the stem cell as not only critical to organogenesis in the embryo, but equally critical to organ function and repair in the adult human. The identification and understanding of genetic malfunction, inflammatory responses, and the progression in chronic disease, begins with a grounding in primary cellular and systemic functions manifested in the study of the early embryo.

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!

Food sources of iodine

Significant losses of naturally occurring iodine or iodine-containing food additives can be caused by
environmental factors in transporting and storing food, and also by processing and cooking.

An analysis of the effects of cooking on the iodine content of fish found that boiling, grilling,
or frying haddock fillets resulted in iodine losses of 58%, 23%, and 20%, respectively.

The amount of iodine in cow’s milk has been linked to the amount of iodine supplemented in the cows’ diet

Iodine is present, but at lower concentrations, in the skeletal muscle of farm animals given
iodine-fortified feed or salt licks as a component of their diet.

Mild iodine deficiency in womb reflects in lowered children's literacy tests

Changes in mother's diet, supplements may prevent long-term neurological impairment.

Children who did not receive enough iodine in the womb performed worse on literacy tests as 9-year-olds than their peers, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).


Iodine is absorbed from food and plays a key role in brain development. Even mild deficiency during pregnancy can harm the baby's neurological development.


"Our research found children may continue to experience the effects of insufficient iodine for years after birth," said the study's lead author, Kristen L. Hynes, PhD, of the Menzies Research Institute at the University of Tasmania in Australia. "Although the participants' diet was fortified with iodine during childhood, later supplementation was not enough to reverse the impact of the deficiency during the mother's pregnancy."

The longitudinal study examined standardized test scores of 228 children whose mothers attended The Royal Hobart Hospital's antenatal clinics in Tasmania between 1999 and 2001. The children were born during a period of mild iodine deficiency in the population. Conditions were reversed when bread manufacturers began using iodized salt in October 2001 as part of a voluntary iodine fortification program.


The study found inadequate iodine exposure during pregnancy was associated with lasting effects. As 9-year-olds, the children who received insufficient iodine in the womb had lower scores on standardized literacy tests, particularly in spelling. However, inadequate iodine exposure was not associated with lower scores on math tests.

Researchers theorize iodine deficiency may take more of a toll on the development of auditory pathways and, consequently, auditory working memory and so had more of an impact on students' spelling ability than their mathematical reasoning ability.


Hynes: "Fortunately, iodine deficiency during pregnancy and the resulting neurological impact is preventable. Pregnant women should follow public health guidelines and take daily dietary supplements containing iodine. Public health supplementation programs also can play a key role in monitoring how much iodine the population is receiving and acting to ensure at-risk groups receive enough iodine in the diet."

The Endocrine Society's clinical practice guidelines on managing thyroid dysfunction during pregnancy and postpartum, including iodine supplementation, are available at http://www.endo-society.org/guidelines/upload/Thyroid-Exec-Summ.pdf.

Other researchers working on the study include: P. Otahal, I. Hay and J. Burgess of the University of Tasmania.

The article, "Mild Iodine Deficiency During Pregnancy is Associated with Reduced Educational Outcomes in the Offspring: 9-Year Follow-Up of the Gestational Iodine Cohort," appears in the May 2013 issue of JCEM.

Founded in 1916, The Endocrine Society is the world's oldest, largest and most active organization devoted to research on hormones and the clinical practice of endocrinology. Today, The Endocrine Society's membership consists of over 16,000 scientists, physicians, educators, nurses and students in more than 100 countries. Society members represent all basic, applied and clinical interests in endocrinology. The Endocrine Society is based in Chevy Chase, Maryland.
