The fetus is considered full-term between weeks 37 and 40 when it is sufficiently developed for life outside the uterus. [ 14 ] [ 15 ] It may be 48 to 53 cm (19 to 21 in) in length when born. Control of movement is limited at birth, and purposeful voluntary movements continue to develop until puberty .
Using the LMP (last menstrual period) method, a full-term human pregnancy is considered to be 40 weeks (280 days), though pregnancy lengths between 38 and 42 weeks are considered normal. A fetus born prior to the 37th week of gestation is considered to be preterm. A preterm baby is likely to be premature and consequently faces increased risk of ...
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.
A pregnancy is considered term at 37 weeks of gestation. It is preterm if less than 37 weeks and postterm at or beyond 42 weeks of gestation. American College of Obstetricians and Gynecologists have recommended further division with early term 37 weeks up to 39 weeks, full term 39 weeks up to 41 weeks, and late term 41 weeks up to 42 weeks.

Preterm birth, also known as premature birth, is the birth of a baby at fewer than 37 weeks gestational age, as opposed to full-term delivery at approximately 40 weeks. [1] Extreme preterm [2] is less than 28 weeks, very early preterm birth is between 28 and 32 weeks, early preterm birth occurs between 32 and 34 weeks, late preterm birth is ...
Definition. A late termination of pregnancy often refers to an induced ending of pregnancy after the 20th week of gestation, i.e. after a fetal age (time since conception) of about 18 weeks. The exact point when an abortion is considered late-term, however, is not clearly defined.
Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis. Fundal height, when expressed in centimeters, roughly corresponds to gestational age in weeks between 16 and 36 ...
A preterm baby is born before the gestational age of 37 weeks. A pregnancy that lasts 41 weeks up to 42 weeks is called late-term and a pregnancy longer than 42 weeks is called post-term . [ 10 ] The general consensus is that a fetus is viable at 24 weeks, however, a live birth may occur earlier in gestation with the assistance from neonatal ...
