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 ...
Sonography can demonstrate that the pregnancy is outside an empty uterus, there is reduced to no amniotic fluid between the placenta and the fetus, no uterine wall surrounding the fetus, fetal parts are close to the abdominal wall, the fetus has an abnormal lie, the placenta looks abnormal and there is free fluid in the abdomen.
While a fetus of ectopic pregnancy is typically not viable, very rarely, a live baby has been delivered from an abdominal pregnancy. In such a situation the placenta sits on the intra-abdominal organs or the peritoneum and has found sufficient blood supply. This is generally bowel or mesentery, but other sites, such as the renal (kidney), liver ...
A lithopedion (also spelled lithopaedion or lithopædion; from Ancient Greek: λίθος "stone" and Ancient Greek: παιδίον "small child, infant"), or stone baby, is a rare phenomenon which occurs most commonly when a fetus dies during an abdominal pregnancy, [1] is too large to be reabsorbed by the body, and calcifies on the outside as ...
When developed enough to survive outside the womb, the cervix dilates and contractions of the uterus propel the fetus through the birth canal, which is the vagina. The ova, which are the female sex cells, are much larger than the sperm and are normally formed within the ovaries of the fetus before its birth.
In all types of LBWC, some of the fetus's organs develop outside of its body, [6] and the placenta will adhere to the affected body structure (cranium, thorax, or abdomen). [7] The umbilical cord is significantly shortened. As a consequence, the developing spine and limbs are contorted, leading to scoliosis and limb defects. [1]
The baby was found swaddled in a towel inside a basket and breathing weakly with the umbilical cord still attached around 3 a.m. on Tuesday, Jan. 21, News 4 (WOAI) San Antonio reported on Jan 24.
The view of those in favor is that these embryos would otherwise be discarded, and if used as stem cells, they can survive as a part of a living human person. A portion of stem cell researchers use embryos that were created but not used in in vitro fertility treatments to derive new stem cell lines. Most of these embryos are to be destroyed, or ...
