Will a small uterus affect pregnancy?

The uterus is the most important organ in every woman's body, and it also has the important task of nurturing life. A small uterus is also a problem encountered by many women. A small uterus is a female physical disease, generally due to developmental delay or long-term malnutrition. A small uterus needs to be treated in time. If the thickness of the uterus and ovulation are normal, it will not affect pregnancy.

Will a small uterus affect pregnancy?

Under normal circumstances, the uterus is 7-8cm long, 4-5cm wide, 2-3cm thick, and the uterine cavity volume is 5ml.

If the uterus is small, as long as it is not too small and menstruation and ovulation are normal, you can get pregnant normally. If a woman's uterus is much smaller than normal, she may experience infrequent menstruation, amenorrhea or even amenorrhea, which will affect normal conception.

Female infertility caused by a small uterus is mainly manifested in the uterus' inability to transport sperm and semen normally, making it impossible for sperm to obtain and conceive. Abnormal uterine morphology and volume and poor development of the uterine muscle layer are not conducive to the implantation of the fertilized egg, implantation and embryo development, and can easily lead to early pregnancy miscarriage, abnormal placental position, fetal growth retardation, etc.

Small and underdeveloped uterus is mainly caused by endocrine dysfunction, especially ovarian dysfunction leading to insufficient secretion of estrogen and progesterone. It is recommended to go to a regular professional hospital to find out the cause and actively treat it.

An immature uterus, also known as uterine hypoplasia, refers to a uterus with normal structure and shape, but a smaller size and a relatively long cervix, which is an important reason for infertility. There are two common types of immature uterus in clinical practice: one is the adolescent uterus, which is more common, and the ratio of the uterine cavity to the cervical canal is about 1:1; the other is the infantile type, and the ratio of the uterine cavity to the cervical canal is about 1:2, and it is often accompanied by ovarian hypoplasia.

Clinical manifestations

Delayed menarche accompanied by oligomenorrhea, dysmenorrhea, or even amenorrhea is often an important clinical manifestation of uterine dysplasia. It is necessary to understand the size of the uterus and whether other endocrine systems are normal, whether there are abnormalities or dysfunctions in organs such as the hypothalamus, pituitary gland, ovaries, whether there are ovulation disorders, and whether the basic conditions for fertility are met. Under normal circumstances, when a woman matures, her uterus naturally becomes capable of reproduction. If abnormalities occur in organs such as the pituitary gland, hypothalamus, and ovaries, leading to endocrine dysfunction, uterine development will be slow, and other secondary sexual characteristics will inevitably be affected, which can lead to infertility.

When women reach the age of sexual development, their menstruation is delayed or infrequent, their breasts do not show obvious swelling, their pubic hair is sparse, and even when their menstruation comes, the amount is very small, this situation should be viewed with caution.

examine

Gynecological examination, B-ultrasound examination, and hysterosalpingography can confirm the diagnosis. Patients with severe uterine dysplasia often have combined endocrine dysfunction and systemic diseases. Therefore, it is necessary to do six sex hormone tests and other organ function tests at the same time.

diagnosis

1. B-ultrasound measurement of uterine body

Uterine hypoplasia can only be diagnosed when the length, width and thickness of the uterus measured by B-ultrasound are less than 5 cm, 4 cm and 2 cm respectively. A vaginal ultrasound is more accurate than a regular abdominal ultrasound. It should be noted that a diagnosis should never be made rashly based on simple B-ultrasound measurements or even just gynecological internal examinations.

2. Measuring uterine capacity

The method to measure the size of the uterus is to measure the capacity of the uterus. If the capacity is less than 5 ml, it can be diagnosed as uterine dysplasia. This diagnostic method requires injecting liquid into the uterine cavity for measurement, which is somewhat painful.

However, these two diagnostic methods may lead to certain misdiagnosis.

3. Others

Six sex hormone tests, pituitary stimulation test, vaginal color Doppler ultrasound, hysterosalpingography, and laparoscopic exploration when necessary. The specific treatment plan depends on the examination results.

treat

Among patients who have been confirmed to have uterine dysplasia, most patients can achieve good treatment results, except for a few who have congenital developmental disorders and are difficult to treat. Therefore, in order to achieve better therapeutic effects, it is also necessary to determine whether uterine dysplasia is a congenital developmental disorder. After exclusion, endocrine drugs can be used for treatment.
