Obstetric conjugate is an important parameter of the birth canal, characterizing its position. It represents the distance between the uterine cavity and the pubic symphysis in the lower segment and ranges from 8 to 12 cm for a normal woman in labor.

The uterine cavity has the shape of a truncated cone, with the open end facing upward, and the other end is closed by the placental membrane during pregnancy and the opening of the uterine pharynx during childbirth. Accordingly, the width of the lower segment of the uterus is approximately 7-9 cm, and the upper border of the overlying part becomes wider. It expands due to increasing panostia of the uterus, an increase in its volume during a pregnant uterus. Nulliparous women have minimal conjugate. This difference between the conjugate of a nulliparous woman and the conjugate of women who have given birth may be greatest in cases where labor occurs primarily through uterine contractions. The duration of labor in nulliparous and parous women is 20% less. In gynecology, the terms “true” and “false” can also be used.

The significance of the obstetric conjugate is to reduce the likelihood of perineal rupture, the integrity of the relaxation sphincter, and the prevention of labor anomalies.

When selecting delivery tactics, the obstetric template takes into account the length and type of the baby’s head, the calculated weight of the child, the diameter of the amniotic sac, the anatomical features of the female body, some diseases of the female part, and the condition of the uterus. One of the methods of prolonging and facilitating spontaneous birth is sometimes used surgical manipulation - epidural anesthesia.

If your gynecologist does not provide adequate and clear information about how to give birth, contact another OB/GYN.
