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]
Women between the ages of 16 and 35 have a healthier environment for a fetus than women under 16 or over 35. [29] Women between this age gap are more likely to have fewer complications. Women over 35 are more inclined to have a longer labor period, which could potentially result in death of the mother or fetus.
The International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) recommends that pregnant women have routine obstetric ultrasounds between 18 weeks' and 22 weeks' gestational age (the anatomy scan) in order to confirm pregnancy dating, to measure the fetus so that growth abnormalities can be recognized quickly later in pregnancy ...
A review of 128 cases by T.S.P. Tien found that the mean age of women with lithopedia was 55 years at the time of diagnosis, with the oldest being 100 years old. The lithopedion was carried for an average of 22 years, and in several cases, the women became pregnant a second time and gave birth to children without incident.
Ensoulment. In religion and philosophy, ensoulment is the moment at which a human or other being gains a soul. Some belief systems maintain that a soul is newly created within a developing child and others, especially in religions that believe in reincarnation, that the soul is pre-existing and added at a particular stage of development.
e. Human embryonic development or human embryogenesis is the development and formation of the human embryo. It is characterised by the processes of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, the development of the human body entails growth from a one-celled ...
Obstetrics, pediatrics. Large for gestational age ( LGA) is a term used to describe infants that are born with an abnormally high weight, specifically in the 90th percentile or above, compared to other babies of the same developmental age. [ 1][ 2][ 3] Macrosomia is a similar term that describes excessive birth weight, but refers to an absolute ...
Ages are given as age from fertilization rather than as gestational age. Some sources contend that there is no voluntary movement until after birth. [3] Other sources say that purposive movement begins months earlier. [4] 3D ultrasound has been used to create motion pictures of fetal movement, which are called "4D ultrasound". [5]
