Research in utero focuses on studying the development and health of a fetus during pregnancy. This area of research is important for understanding how factors such as maternal health, environmental exposures, and genetics can impact the growth and development of the fetus. Researchers in this field use various techniques, such as ultrasound imaging, blood tests, and genetic testing, to monitor the health and well-being of the fetus throughout pregnancy. By studying the in utero environment, researchers aim to improve prenatal care and outcomes for both mother and baby.
