Fetus Growth: Many variation in the growth of fetus. Fetus growth depend on stage by stage . Definitely growth depend on time. When fetal size is less than expected, that condition is known as intrauterine growth restriction also called fetal growth restriction , factors affecting fetal growth can be maternal placental or fetal.
Maternal factors: there are to many maternal factors for fetus growth , include maternal weight, body mass index, nutritional state, emotional stress, toxin exposure, tobacco, alcohol, heroine other drugs which can also harm the fetus in other way and uterine blood flow.
Placental factors are , size, umbilical blood flow, transporters, microstructure, binding protein, nutrient utilization and nutrient production.
Fetal factors are fetus genome, nutrient production hormone output, female fetus tend to weight loss than male at the full term.
Fetal growth is classified as below,
a) Small for gestational (SGA)
b) Appropriate for gestational age (AGA)
c) Large for gestational age (LGA)
SGA can result in low birth weight or loss weight birth, although premature birth can also result in low birth weight. Low birth weight increase risk for prenatal mortality.

Human pregnancy is the carrying of one or more offspring, termed as a fetus or embryo in the womb of mother. In a pregnancy there can be multiple gestations as in the case of twins or triples zygote. It occurs when one ovum is fertilized by two separate sperm or one ovum is fertilized by one sperm, after the formation of the zygote it divides form two separate zygote which may have separate embryonic sac or not , the after birth it terms as twin or triplets. The world health organization defines normal time for delivery as between 37 weeks and 42 weeks.
The date of a child birth counted from the las normal menstrual cycle length of four weeks. Usually one pregnancy takes 40 weeks.
A fetus also spelled foetus, faetus or faetus is a developing mammal or other viviparous vertebrate after the embryonic stage before birth in humans. The fetal stage begins from the 11th weeks is gestational age which is the 9th week after fertilization. Fetus containing weight at this age 400 grams approximately.
Low birth weight is defined as 2500 grams (5.51b). low birth weight is fetus is concern for fetus growth. Smoking during pregnancy may also lead to reduce the fetus weight and size.
