From the moment a woman becomes pregnant, people want to know whether she is carrying a boy or a girl. As a pregnant woman, many people want to know the gender of their baby as soon as possible. In fact, at a certain stage of pregnancy, the gender of the fetus can be detected through ultrasound. So how long can pregnancy determine gender?
How many months can an ultrasound detect boys and girls?
Firstly, it should be declared that China's laws prohibit non-medical fetal gender identification, which means that hospitals will not perform medical fetal gender identification on you. However, conducting fetal gender identification in Hong Kong is legally recognized. Generally, at four months of pregnancy, the gender of the fetus can be determined through ultrasound examination.
Observing male and female students through ultrasound
1. The ratio of fetal length to width: If the ratio of length to width is greater than three times, the probability of boys is higher, otherwise it is girls
2. Looking at the shape of the fetus: A long strip is more likely for male babies, while a round one is more likely for female babies.
3. The size of the gestational sac: those with large differences in data give birth to boys, while those with small differences give birth to girls. For example, 39mmX30mmX25mm gives birth to boys, and 35mmX34mmX28mm gives birth to girls.
4. Fetal placenta: There are 2 umbilical arteries, and no pressure marks are found on the skin of the neck. It should be a boy.
5. Fetal Head and Face: The fetal head is located on the pubic bone, the skull halo is smooth, the midline of the brain is centered, and the fetal upper lip and nasal bone can indicate the birth of a boy.
6. Fetal amniotic fluid maximum depth: 47mm, excellent sound transmission, for boys.
