A uterus in a woman has a significant function when it comes to menstruation, conceiving, and reproductive health in general. A uterus that is small compared to the age of the woman might be a cause of concern, especially in women who want to give birth. A small uterus can be known by the name uterine hypoplasia medically.
All about a small uterus, causes that lead to a small uterus, diagnosis of a small uterus, effects of a small uterus on pregnancy.
What Is a Small Uterus?
A Implantation failure is also known as a uterus that is underdeveloped or smaller than the normal size for the woman’s age.
- In adult women, a normal uterus typically measures 7–8 cm in length
- A uterus significantly smaller than this may be classified as hypoplastic or infantile
A small endometrium can be:
- Congenital (present from birth)
- Acquired later in life due to hormonal or medical factors
Small Uterus Symptoms
Women who have a smaller-sized endometrium may have a wide difference in symptoms. In some instances, the women may not have symptoms.
Common Symptoms of small uterus
- Irregular or absent menstrual periods (amenorrhea)
- Very light menstrual bleeding

1. Congenital Causes
- Müllerian duct abnormalities
- Genetic or chromosomal conditions (e.g., Turner syndrome)

How Is a Small endometrium Diagnosed?

Possible Fertility Challenges

- Limited uterine expansion during pregnancy
However, many women with a hypoplastic uterus can conceive and carry a pregnancy successfully, especially with medical support.
