William Hunter’s Anatomia Uteri Humani Gravidi Tabulis Illustrata (The Anatomy of the Human Gravid Uterus Exhibited in Figures), hereafter called The Human Gravid Uterus, is an anatomical atlas depicting the pregnant form through both engravings and descriptions. William Hunter, an anatomist working in England during the eighteenth century, compiled the work based on observations from his dissections of pregnant women. The collection of thirty-four copper plate illustrations details the anatomy of the pregnant human womb (gravid uterus), and includes depictions of unborn fetuses at various stages of development. Hunter compiled The Human Gravid Uterus to provide an objective anatomical depiction of pregnancy and development at a time when midwifery and obstetrics were becoming prominent fields of medical practice in England.

Congenital rubella syndrome (CRS) can occur in children whose mothers contracted the rubella virus, sometimes called German measles, during pregnancy. Depending on the gestational period when the mother contracts rubella, an infant born with CRS may be unaffected by the virus or it may have severe developmental defects. The most severe effects of the virus on fetal development occur when the mother contracts rubella between conception and the first trimester. Defects from maternal rubella in the first trimester are included in the term congenital rubella syndrome, but physicians and researchers specifically refer to those defects as rubella embryopathy. Developmental defects are less severe if the mother contracts rubella in the second trimester, and they are generally negligible if the infection occurs in the third trimester. Prenatal rubella infection can cause birth defects which include deafness, compromised vision, abnormal heart development, and damage to the central nervous system which can lead to compromised cognition and learning disabilities.

In a clinical trial from 1969 to 1972, Sir Graham Collingwood Liggins and Ross Howie showed that if doctors treat pregnant women with corticosteroids before those women deliver prematurely, then those women's infants have fewer cases of respiratory distress syndrome than do similarly premature infants of women not treated with corticosteroids. Prior to the study, premature infants born before 32 weeks of gestation often died of respiratory distress syndrome, or the inability to inflate immature lungs. Liggins and Howie, then both at the University of Auckland in Auckland, New Zealand, published their results in A Controlled Trial of Antepartum Glucorticoid Treatment for Prevention of the Respiratory Distress Syndrome in Premature Infants in 1972. The study built on experiments Liggins had earlier conducted with sheep. Liggins' corticosteroid experiments changed the way doctors treated pregnant women experiencing preterm labors, and they improved the life expectancy of prematurely born infants.
