Corpus cervix ratio up to 10 years of ages
A. 3:2
B. 2:1
C. 1:2
D. 3:1
Correct Answer: B. 2:1
Explanation : Good question. Here’s a summary of what medical literature says about the Uterus — specifically the ratio of the uterine corpus (body/fundus) to the cervix in pre-pubertal girls (up to ~10 years of age).
What is known: corpus-to-cervix ratio in childhood
• In neonates and very young girls, the uterus tends to be “tubular,” and the cervix is larger (longer, thicker) than the uterine body.
• Many sources report that in early childhood (infancy until a few years), the corpus:cervix ratio is ≈ 1:2 (i.e. cervical part is twice the body).
• As children grow (pre-pubertal period), around 7–10 years, the uterus gradually grows, and the relative size of the corpus increases.
• During this transitional period (around 7–10 years), many sources describe the corpus:cervix ratio to approach 1:1 (body approximating cervix) or slightly more.
• In a standard sonographic classification:
• “Infantile uterus”: corpus:cervix = 1:2
• “Transitional uterus” (early pre-puberty): corpus:cervix ≈ 1:1
• At puberty, corpus becomes larger than cervix: ratio shifts to ~2:1 (or higher) in adult-like uterus.
Thus, by about age 10 (pre-pubertal but approaching puberty), the ratio may already be approaching 1:1 or slightly less corpus relative to cervix — but corpus generally remains smaller than cervix for most of childhood.
Typical Values / Ranges
From literature sources:
Age / Stage Uterine configuration Corpus : Cervix (approximate)
Neonatal / infancy Tubular / cervix-dominant ~ 1 : 2
Pre-school / early childhood Tubular, cervix dominant ~ 1 : 2
~ 7–10 years (pre-pubertal) Slight growth of corpus — transitional ~ 1 : 1 (sometimes a little less corpus)
So, for “up to 10 years of age,” the commonly accepted textbook/sonographic ratio is either 1:2 (infantile uterus) or approaching 1:1 (transitional), depending on the exact age and individual variation.
Important caveats / variation
• There is no single fixed value; there’s variation depending on individual development, ethnicity, nutrition, and other factors. Sonographic studies have shown a range of normal uterine size and proportions in pre-pubertal girls.
• The exact demarcation between “corpus” and “cervix” may be somewhat subjective, especially in very small uteri, so ratio estimates are approximate.
• Growth is gradual: corpus size increases slowly as the child grows, but major change toward adult proportions happens during puberty under hormonal influence.
So — Answer to your question
If you ask “What is the corpus:cervix ratio up to 10 years of age?”, a reasonable accepted answer is:
• Usually ~ 1:2 in infancy and early childhood — cervix larger than corpus.
• Approaching ~ 1:1 by 7–10 years (pre-pubertal), though corpus is often still equal to or slightly smaller than cervix.
