Gestation refers to the period of development of a fetus inside the womb of a mother, from the time of conception to birth. Research in this area typically focuses on understanding the various biological, physiological, and environmental factors that influence and impact the development of the fetus during this crucial time. This includes studying aspects such as fetal growth, organ development, maternal-fetal interactions, and the effects of prenatal influences on later health and development. Researchers in this field may also investigate ways to optimize gestational outcomes and reduce risks for complications during pregnancy.
