Fetal viability is the ability of a human fetus to survive outside the uterus. Viability depends upon factors such as birth weight , gestational age, and the availability of advanced medical care . In low-income countries , more than 90% of extremely preterm newborns (less than 28 weeks gestational age ) die due to a lack of said medical care ...
A human fetus, attached to placenta, at three months gestational age. In humans, the fetal stage starts nine weeks after fertilization. [7] At this time the fetus is typically about 30 millimetres (1 + 1 ⁄ 4 in) in length from crown to rump, and weighs about 8 grams. [7] The head makes up nearly half of the size of the fetus. [8]
Baby weighed as appropriate for gestational age. Birth weight is the body weight of a baby at their birth. [ 1] The average birth weight in babies of European and African descent is 3.5 kilograms (7.7 lb), with the normative range between 2.5 and 4.0 kilograms (5.5 and 8.8 lb). [ 2]
Infant (from the Latin word infans, meaning 'baby' or 'child' [ 1]) is a formal or specialised synonym for the common term baby. The terms may also be used to refer to juveniles of other organisms. A newborn is, in colloquial use, an infant who is only hours, days, or up to one month old. In medical contexts, a newborn or neonate (from Latin ...
In obstetrics, Leopold maneuvers are a common and systematic way to determine the position of a fetus inside the woman's uterus. They are named after the gynecologist Christian Gerhard Leopold. They are also used to estimate term fetal weight. [ 1] The maneuvers consist of four distinct actions, each helping to determine the position of the fetus.
[4] [5] This is just over nine months. Counting by fertilization age, the length is about 38 weeks. [5] [13] Pregnancy is "the presence of an implanted human embryo or fetus in the uterus"; implantation occurs on average 8–9 days after fertilization. [15]
There is no sharp limit of development, gestational age, or weight at which a human fetus automatically becomes viable. [13] According to studies between 2003 and 2005, 20 to 35 percent of babies born at 23 weeks of gestation survive, while 50 to 70 percent of babies born at 24 to 25 weeks, and more than 90 percent born at 26 to 27 weeks ...
