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!

WHO Child Growth Charts

Spontaneous abortion is estimated to affect 15 percent of women, mainly in the first trimester of pregnancy.

Scientists at the University of Granada have confirmed that a low plasma level of copper and zinc in pregnant women may be a factor associated with spontaneous abortion, a hypothesis that had not been confirmed to date, and which had never been proven in humans before.

For the purpose of this study, 265 pregnant women participated in the tests. From these 265 women, 132 had suffered a spontaneous miscarriage during the year of the test. The rest (133) were women with evolutionary pregnancy, selected among pregnant women attending a scheduled birth control appointment.

All study members underwent an ultrasound examination, and blood sample for laboratory tests. Additionally, each was asked to answer a questionnaire. In total, 131 variables were assessed from each participant.

The data obtained from the group of women who had suffered a miscarriage were compared with those obtained from the group of women with a normal pregnancy. The results proved the existence of differences in maternal plasma concentrations of copper and zinc.

This finding suggests that maternal deficiency of one or both trace elements may be associated with the occurrence of spontaneous abortion, which opens new and interesting lines of research in this area so far unexplored.

Apart from the influence that copper and zinc may have on the occurrence of abortions, the research conducted at the UGR has provided relevant information about other variables previously studied, but significantly unknown as homocysteine, preconception and prenatal supplementation with iodine and folate, thyroid dysfunction or consumption of drugs in the first weeks of pregnancy.

This study was carried out by Jesús Joaquín Hijona Elósegui, a researcher at the Department of Pharmacology of the University of Granada, and conducted by professors Manuel García Morillas and Juan Antonio Maldonado Jurado.

UGR scientists determined that most of the pregnancies (64 percent) that ended in abortion in the study were planned pregnancies, although only 12 percent of patients had used the recommended supplements of iodine and folate before attempting to become pregnant - these substances have been proven to decrease the rate of abortions and malformations.

In addition, a third of the women who miscarried reported to be regular smokers and 16.6 percent regularly consumed coffee at a dose that exceeded the abortifacient and teratogenic threshold. The consumption of tobacco and caffeine of certain doses has been strongly associated with the occurrence of spontaneous abortion.

During pregnancy, 81.07 percent of the women who suffered a miscarriage had taken some drug officially contraindicated during pregnancy, and 13.63 percent were exposed to some drug considered dangerous during pregnancy.

As doctor Hijona points out “despite the significant progress made in reproductive medicine, spontaneous abortion is still the most frequent complication during pregnancy."

"It is estimated to affect 15 percent of pregnant women, mainly during the first trimester. Although most of the time it is not recurring, there is a recurrence of two to five percent among women who have already suffered a miscarriage.”

There are data available showing an increase in the number of miscarriages among the Spanish population. In recent years, the number of pregnant women who suffers a miscarriage has increased gradually. This is not only due to the increase in the number of pregnancies, but also to the increase in the percentage of miscarriages –from 10.39 percent in 2003 to 13.70 percent in 2010).

The results obtained in this study were published in the Spanish journals Progresos de Obstetricia y Ginecología (the official journal of the Spanish Society of Gynaecology and Obstetrics), in Toko-Ginecología Práctica, and in Obstetrics and Gynaecology.
