The optimal time for 4D ultrasound examination is between 22-26 weeks for expectant mothers. Due to individual differences, the specific time for performing four-dimensional ultrasound should be confirmed by the doctor after various examinations.
The four-dimensional color ultrasound diagnostic device is currently the most advanced color ultrasound equipment in the world. Many pregnant women who have undergone four-dimensional color ultrasound will habitually ask the doctor whether the fetus is male or female. Although 4D ultrasound can detect the gender of the fetus, it is illegal to distinguish between male and female fetuses for non-medical purposes according to national regulations. Regular hospitals will not disclose or imply the gender of the fetus through any means. Therefore, during the examination process, in order to avoid revealing the gender of the fetus, doctors will also actively avoid the gender characteristics and lower body of the fetus.
Although doctors do not disclose the gender of the fetus, there is already a set of opinions among the public regarding the use of four-dimensional ultrasound to determine gender:
1. Shape of gestational sac to determine fetal gender
Some people believe that the shape of the gestational sac can indicate whether the fetus is male or female. Generally speaking, if the shape of the gestational sac resembles an eggplant or is elongated, the likelihood of conceiving a male baby is high; If the gestational sac is oval or round, it is likely to be a female baby.
2. Determine fetal gender based on gestational sac size
There is a rumor that if the difference in length and width of the gestational sac is more than twice, then the possibility of a male baby is high. If the length and width are equal or not significantly different, it is likely to be a female baby.
Four dimensional ultrasound can observe the growth and development of fetuses in the uterus from multiple angles and directions, providing accurate scientific basis for early diagnosis of congenital surface deformities and congenital heart diseases in fetuses. The four-dimensional color ultrasound diagnostic device can display real-time dynamic activity images of unborn babies in pregnant women, or real-time activity images of other internal organs in the human body. And the fact that 4D ultrasound can determine the gender of the fetus is because it directly captures the fetal genitalia, not because of the shape and size of the gestational sac!
