This measurement determines the shape of the inlet. 3. The fetus passes under it during birth. 4. The size of this diameter determines whether the fetus can move down into the birth canal so that engagement can occur.

4. The size of this diameter determines whether the fetus can move down into the birth canal so that engagement can occur. Explanation: 4. The obstetric conjugate extends from the middle of the sacral promontory to an area approximately 1 cm below the pubic crest. The fetus passes through the obstetric conjugate, and the size of this diameter determines whether the fetus can move down into the birth canal in order for engagement to occur.
