The baby's gestational age (number of completed weeks of pregnancy) at the time of birth and the baby's weight (also a measure of growth) influence whether the baby will survive. Another major factor is gender: male infants have a slightly higher risk of dying than female infants, [ 41 ] for which various explanations have been proposed.
The sex of the fetus may be discerned by ultrasound as early as 11 weeks' gestation. The accuracy is relatively imprecise when attempted early. [15] [16] [17] After 13 weeks' gestation, a high accuracy of between 99% and 100% is possible if the fetus does not display intersex external characteristics. [18]
Fetal viability typically occurs at about 24 to 25 weeks of gestation. [2] When the fetus is in between the ages of 24–34 weeks, a glucocorticoid is given to the patient about 24 hours before the procedure to stimulate lung maturity. An ultrasound is performed before the procedure to view the position of the fetus and may be used during the ...
The chance of survival at 22 weeks is about 6%, while at 23 weeks it is 26%, 24 weeks 55% and 25 weeks about 72% as of 2016. [189] With extensive treatment up to 30% of those who survive birth at 22 weeks survive longer term as of 2019. [190] The chances of survival without long-term difficulties is less. [24]
Oh baby! One of Hilary Swank's twins is already ready to rumble.. The 48-year-old pregnant actor is in her third trimester with the twins, and she posted a new ultrasound photo on Instagram March ...
Ultrasound is also a common tool for determining viability and location of a pregnancy. Serial ultrasound may be used to identify non-viable pregnancies, as pregnancies that do not grow in size or develop expected structural findings on repeated ultrasounds over a 1–2 week interval may be identified as abnormal.

'This is so wrong to comment on her body.'
By about week 21, the fetus begins to develop a regular schedule of movement. [17] The startle reflex is present in half of all fetuses by week 24 and in all fetuses by week 28. [19] Movement is restricted around this time because the fetus has grown so large it has little space for kicking or changing body position. [20]
