Update: October 2018
The definition of “the child’s uterus in a woman” unites many
terms: hypoplastic uterus, infantile uterus, underdeveloped
uterus. This pathology is currently encountered.
quite often and often accompanied by the difficulties of conception and
pregnancy carrying. The child’s womb in an adult woman can
to be both an independent disease and one of the signs
genital or sexual infantilism.
Characteristic “adult” uterus
The uterus is considered to be the main organ in the female body,
it performs a hormonal function, in its absence impossible
menstruation, and, important moment, pregnancy. During labor the uterus
actively helps the birth of a child, due to
developed muscle layer and its contractions (contractions).
The size of the fruit tree depends on the age
the fair sex. Newborn girl has
the uterus is about 3 cm long, and the cervix is related to the body of the uterus as
3/1. The angle between the neck and the body is not pronounced, and the mass of the uterus is about 4
In the period of childhood, which lasts up to 8 years and ends
By the start of puberty, the size of the uterus undergo
changes. In the first year of life, its length is 2.5 cm, and weight 2.3
gram. By the age of 4, the weight of the uterus increases to 2.8 grams,
and by the sixth birthday of the girl, the weight of the uterus is equal to its weight at birth.
The ratio of the cervix and uterus also changes: by the end of the first year it is early
2/1, by the fourth anniversary – 1.7 / 1, and at 8 years old – 1.4 / 1. If
the newborn uterus is in the abdominal cavity, then by the age of 4 she
descends into the pelvis.
The size of the uterus of a woman of childbearing age depends on
presence / absence of a history of pregnancies:
- there were no pregnancies – length 4.5 cm +/- 3 mm, width 4.6 cm
+/- 4 mm, thickness (anteroposterior size) 3.4 cm +/- 1 mm;
- there were pregnancies, but they were interrupted (abortions, miscarriages) – length 5.3
cm +/- 3 mm, width 5.0 cm +/- 5 mm, thickness 3.7 +/- 1 mm;
- women who have given birth – length 5.8 cm +/- 3 mm, width 5.4 cm
+/- 6 mm, thickness 4.0 +/- 2 mm.
As soon as a woman becomes pregnant, the uterus begins to grow vigorously
(hypertrophy and stretching of muscle fibers), its length to childbirth
reaches 32 – 33 cm and weighs 1.5 kg. After the baby is born, the organ
undergoes involutive changes and gradually returns to
normal size, but remains somewhat heavier and larger than before
Normally, the length of the cervix corresponds to about a third of the uterine
length and is 28 – 37 mm. The thickness of the neck reaches 29 – 53 mm.
The shape of the neck also depends on the presence of a history of labor. Have no birth
women are conical, and those who give birth have a cylindrical shape.
Immature uterus and its extent
Uterine hypoplasia is called such a uterus when it is underdeveloped,
that is, by the end of puberty does not reach the size,
corresponding to normal indicators, and the body itself
formed correctly, has a body, bottom, neck and fallopian tubes.
�”Little” womb is often found in conjunction with hypoplasia.
appendages, vagina and external genital organs, that is, it acts
one of the symptoms of genital infantilism.
The degree of uterine underdevelopment:
- I degree – the size of the uterus in length, measured by a probe not
reach 3.5 cm, besides most of the length belongs to the neck –
such a uterus is called rudimentary or germinal;
- II degree – measured by probe, the length of the uterus is in
the boundaries of 3.5 – 5.5 cm, and the proportion of the neck and body is 3/1 –
this underdevelopment is called infantile or pediatric
- Grade III – the length of the uterine cavity on the probe is 5 – 7
cm and the ratio of the cervix to the uterus in the normal range – 1/3,
a slight lag in the size of the uterus from the norm is called
гиполастичной или подростковой the uterus.
Causes of uterine underdevelopment
This disease may be congenital, that is, due to
factors affecting the maternal organism during
gestation, and acquired.
Congenital uterus of small size, one of the pathognomical
signs of genital infantilism, the causes of which
- chromosomal abnormalities and genetic diseases;
- occupational hazards of the mother during gestation;
- bad habits (smoking and alcohol);
- placental insufficiency and intrauterine retention
- past infections;
- medication intake.
Acquired uterine hypoplasia develops in the background:
- disorders of the regulation of the hypothalamic-pituitary system
(infectious or toxic genesis, trauma);
- tumor formations of the pituitary, hypothalamus;
- postponed infections with a severe course;
- chronic extragenital pathology (heart defects,
diseases of the kidneys and liver, respiratory organs);
- endocrine diseases – diabetes mellitus (see symptoms

- autoimmune processes;
- dyshormonal disorders after severe childhood
infections (mumps, rubella) or ovarian cysts and tumors;
- underdevelopment of the ovaries (in this case, have place hypoplasia

- weight deficit (fasting, malnutrition and malnutrition,
weight loss diets);
- mental disorders (depression, neurosis), stress;
- ovarian surgery (significant damage to the glandular tissue

- toxic factors (drug and alcohol use,
- excessive exercise, professional
- frequent colds;
- mental stress;
- genetic predisposition.
The leading symptom of this pathology is a violation
menstrual cycle. In girls with uterine hypoplasia 1 degree
there is amenorrhea, or extremely rare and scarce bleeding
highlight. With grade 2 and 3, patients complain about
late onset of menstruation (after the 16th anniversary), their
irregularity (long intervals), scanty or, on the contrary,
обильные кровянистые highlight. As a rule, menstruation is very
painful, accompanied by headache, lethargy, nausea and
even fainting. Algomenorrhea is explained by three factors.
- First, reduced uterine elasticity on the eve of menstruation and
tide to the organ of the blood reacts pain impulses.
- Secondly, through the too long and narrow cervical canal
blood and particles of the uterine mucosa pass with difficulty that
aggravates and uterine hyperaflexia (uterus bend).
- Thirdly, the impaired innervation of the body leads to
discoordinated contractions, which leads to the dispatch of pain
impulses to the brain and the occurrence of pain.

Treatment of a disease in adolescents first begins with
correction of nutrition, which should contain the norms of carbohydrates,
protein, fat and is rich in vitamins and trace elements. Special
attention must be paid to the psycho-emotional state of the child
(exclude stress and unnerving situations).
In uterine hypoplasia, hormone therapy is the basis of treatment.

Hormonal drugs (estrogens and progestins) are prescribed in
cyclic mode with a break for menstruation courses of 3 – 4
months and with intervals of 3 months. Stimulant treatment

In case of pathology 1 degree, hormone treatment pursues replacement
