Ivanova-Verbova Theory

The Ivanova-Verbov theory is one of the most common methods for determining gestational age. It was developed by Soviet obstetricians Yakov Fedorovich Verbov and Nikolai Zakharovich Ivanov at the beginning of the 20th century.

According to this theory, the gestational age is determined by several criteria, such as the size of the uterus, the height of the uterine fundus, the volume of the abdomen, the position of the fetus and other factors. In this case, the main criterion is the height of the uterine fundus.

The Ivanova-Verbova theory has a number of advantages over other methods of determining the duration of pregnancy, such as ultrasound or determining the number of weeks of pregnancy by the date of the last menstruation. Firstly, it allows you to determine the duration of pregnancy with an accuracy of several days, which is especially important for women with irregular menstrual cycles. Secondly, it does not require the use of special equipment and can be used in any medical clinic or maternity hospital.

However, like any other method of determining gestational age, the Ivanova-Verbov theory is not without its drawbacks. For example, it may not be accurate if a woman has weight or height problems or is at risk for pregnancy complications.

In general, the Ivanova-Verbov theory remains one of the most popular methods for determining gestational age in Russia and many other countries. It allows you to get accurate results without the use of special equipment, which makes it accessible to a wide range of women.



Ivanova-Verbova theory is an innovative approach to the theory of the relationship between a woman in labor and a child during childbirth and after it. Four main directions of this theory have been developed, which contribute to the successful resolution of labor in expectant mothers and the correct behavior of the mother in labor at this important moment.

In the 19th century, the birth of a child was a completely unpredictable event. During childbirth, some mothers died, and other children were stillborn or completely disabled. This phenomenon could have its social consequences, and therefore in the 20th century there was a need for research to help prevent these incidents.
