Fetal height, fetal weight, head circumference (HC), crown to rump length (CR), dermatological observations like skin thickness etc. are measured individually to assess the growth and development of the organs and the fetus as a whole and can be a parameter for normal or abnormal development also including adaptation of the fetus to its newer ...
An abnormally slow growth rate results in the infant being small for gestational age, while an abnormally large growth rate results in the infant being large for gestational age. A slow growth rate and preterm birth are the two factors that can cause a low birth weight. Low birth weight (below 2000 grams) can slightly increase the likelihood of ...
Linear growth is a complex process regulated by the growth hormone (GH) – insulin-like growth factor-1 axis, the thyroxine/triiodothyronine axis, androgens, estrogens, vitamin D, glucocorticoids and possibly leptin. [25] GH is secreted by the anterior pituitary gland in response to hypothalamic, pituitary and circulating factors.

An ultrasound showing an embryo measured to have a crown-rump length of 1.67 cm and estimated to have a gestational age of 8 weeks and 1 day. Crown-rump length (CRL) is the measurement of the length of human embryos and fetuses from the top of the head (crown) to the bottom of the buttocks (rump).
The CDC growth reference charts define the normal range of growth as between the 5th and 95th percentiles. [ 4 ] While it is common for babies to shift percentiles during the first 2 years of life due to shifting from an intrauterine environment to one outside the uterus, shifting percentiles after 2 years of age may be the first sign of an ...

Fetal macrosomia and LGA often do not present with noticeable patient symptoms. Important signs include large fundal height ( uterus size) and excessive amniotic fluid ( polyhydramnios ). [ 6 ] Fundal height can be measured from the top of the uterus to the pubic bone and indicates that the newborn is likely large in volume.
