The size of the gestational sac is not indicative of the sex of the fetus, nor does it have any scientific basis, and sex determination of the fetus is firmly prohibited in China.
The size of the gestational sac is determined by a number of factors, such as the duration of pregnancy, nutrition, location of implantation, and the size of the uterine cavity. Everyone’s uterine cavity is different, and the size of the gestational sac naturally changes with the size of the uterine cavity. The size of the gestational sac is also related to the number of days of pregnancy and the condition of the examination at that time, as well as the ultrasonographer’s technique.
The size of the gestational sac varies depending on the number of days of pregnancy, and the direction of the ultrasound probe varies from doctor to doctor, so the size and shape of the gestational sac may change when viewed from different angles. The size and shape of the gestational sac also looks flatter when the uterus is compressed due to holding the urine for a longer period of time.
The size of the gestational sac is different for everyone and it is determined by its tone and the amount of amniotic fluid it contains, which changes on its own during each period.
Fetal sex determination during pregnancy is illegal except in cases of medical necessity, and there is no scientific basis for assessing the sex of a fetus through the shape and size of the gestational sac, so please do not believe in individual cases to apply it.
Please take pregnancy test on time during pregnancy, and if there is any abnormality, please seek medical advice as soon as possible to avoid adverse consequences.
