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 ...
Upon viability, the pregnancy can be terminated, as by a c-section or induced labor, with the fetus surviving to become a newborn infant. Several groups believe that abortion before viability is acceptable, but is unacceptable after." [29] [30] [31] In some countries, early abortions are legal in all circumstances but late-term abortions are ...
Fetal viability refers to a point in fetal development at which the fetus may survive outside the womb. The lower limit of viability is approximately 5 + 3 ⁄ 4 months gestational age and is usually later. [20] There is no sharp limit of development, age, or weight at which a fetus automatically becomes viable. [21]
The fetus reaches a length of about 40–48 cm (16–19 in). The fetus weighs about 2.5 to 3 kg (6 lb 10 oz)to 6 lb 12 oz). Lanugo begins to disappear. Body fat increases. Fingernails reach the end of the fingertips. A baby born at 36 weeks has a high chance of survival, but may require medical interventions. Fetus at 38 weeks after fertilization.
This fetal period is described both topically (by organ) and chronologically (by time) with major occurrences being listed by gestational age. The very early stages of embryonic development are the same in all mammals, but later stages of development, and the length of gestation varies.
One fetus died around 14 weeks, and a month later I went into preterm labor – likely caused by the death of the first and an infection. I delivered the second twin, who appeared perfectly ...
After the fetus is expelled from the maternal body it is called a neonate. Whether the birth is vaginal or by caesarean section , and whether the neonate is ultimately viable, is irrelevant. The definition of the term "live birth" was created by the World Health Organization in 1950, and is chiefly used for public health and statistical purposes.
Even in states where abortion is legal, many restrict the procedure after 'fetal viability.' Here's what that means and why some abortions happen later in pregnancy.
