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!

Simple Treatment Prevents Premature Births
Treating high-risk pregnant women with the hormone progesterone cut their rate of early delivery by 45 % and helped lower the risk of breathing complications in their babies.

Babies Are Born Early Near Busy Road Intersections
Babies are born earlier when their mothers live near a concentration of freeways and main roads, reports a study of 970 mothers and their newborn babies in Logan City, a town south of Brisbane, Australia.

New Gene Influencing Risk For Developing Epilepsy
Vanderbilt University researchers have identified a new gene that can influence a person's risk for developing epilepsy.

Gene Linked To Autism's Social Dysfunction
With the help of two sets of brothers with autism, Johns Hopkins scientists have identified a gene associated with autism that appears to be linked very specifically to the severity of social interaction deficits.

Study Reveals How Eye Is Formed
Scientists at King’s College London have discovered specific cells responsible for ensuring that different parts of the eye come together during development.

Findings published online in the journal Ultrasound in Obstetrics and Gynecology offer a relatively simple way to prevent premature birth in women with a short cervix, a known cause of preterm birth.

"The study published today offers hope to women, families and children," Dr. Roberto Romero, chief of the perinatology research branch of the National Institutes of Health, said in a statement.

"Worldwide, more than 12 million premature babies - 500,000 of them in this country - are born each year, and the results are often tragic. Our clinical study clearly shows that it is possible to identify women at risk and reduce the rate of preterm delivery by nearly half, simply by treating women who have a short cervix with a natural hormone - progesterone," says Romero.

Babies born too early - before the 33rd week of pregnancy - have a higher risk of early death and long-term health and developmental problems.

In the United States, 12.8 percent of babies were born preterm in 2008, raising their risk of dying in their first year and having breathing difficulties, cerebral palsy, learning disabilities, blindness and deafness.

The study, done by researchers at the NIH and 44 medical centers around the world, looked at effects of giving progesterone to women with a short cervix, which is the part of the uterus that opens and shortens during labor.

Researchers suspect that women with a short cervix may not have enough of this hormone, and giving it during pregnancy in a gel form might help prolong their pregnancies.

The team studied 458 women with a short cervix who got either a vaginal gel containing progesterone or a placebo between the 19th and 23rd week of pregnancy.

Only 8.9 percent of women who got the gel delivered before the 33rd week of pregnancy, compared with 16.1 percent who were in the placebo group.

The treatment also helped babies. Only 3 percent of babies born to women treated with progesterone had respiratory distress syndrome compared with 7.6 percent of babies in the placebo group.

"We have for a long time known that short cervix is associated with an increased risk of preterm birth," said Dr. Ashley Roman of New York University's Langone Medical Center, who was not involved with the research.

Roman said other studies have shown that progesterone can cut the risk of premature birth in women with this problem. She said the NIH study is important because it shows that the treatment also reduces respiratory problems in newborn babies.

"Not only are fewer babies being delivered preterm, fewer babies have medical problems associated with prematurity," she said in a statement.
