Is it accurate to determine the gender of a baby by the pH value of a pregnant woman?

Pregnant women are always very curious about whether the baby in their belly is a boy or a girl, and people always want to obtain the gender characteristics of the baby in their belly through various means. Some say that it is judged by the shape of the pregnant woman's belly; some say it is judged by the changes in the pregnant woman's appearance and skin; some say it is judged by the changes in the pregnant woman's taste. Looking at the pH value of the pregnant woman is also a familiar method. So is the pH value of the pregnant woman accurate in judging the gender of the baby?

The statement that the pH value of urine test can determine the gender of the baby is relatively accurate. The pH value of urine test is the most accurate when the baby is two or three months pregnant. If the pH value at this time is greater than or equal to 7.0, it is likely to be a boy. If it is less than 7.0, it is likely to be a girl.

Other identification methods:

Symptom 1: Judging symptoms from the shape of the pregnant woman’s belly

If a pregnant woman's belly is pointed, she will be pregnant with a boy; if her belly is round, she will be pregnant with a girl.

Comment: The shape of a pregnant woman's belly is largely determined by the size of the fetus and its posture in the uterus. The average weight of a male fetus is higher than that of a female fetus, but the difference is not enough to make a noticeable difference in the bulge of a pregnant woman's belly. The posture of the fetus will also determine the shape of the pregnant woman's belly. If the fetus is facing away from the mother in the womb, the pregnant woman's belly will be more prominent; conversely, if the fetus is facing the mother in the womb, the abdomen will be flatter. It can be seen that the shape of a pregnant woman's belly has nothing to do with the gender of the fetus.

Symptom 2: Observe changes in the appearance and skin of pregnant women

If a pregnant woman's appearance becomes beautiful and her skin becomes smooth, she may be pregnant with a girl; on the contrary, if her appearance becomes uglier, her skin becomes rough, or even her face is covered with acne, she may be pregnant with a boy.

Comment: People who believe this statement think that this is because fetuses of different genders stimulate the mother to secrete different levels of hormones after pregnancy, which causes changes in the pregnant woman's face. In fact, compared to before pregnancy, regardless of the gender of the fetus, the hormone levels in the mother's body will change significantly, and the secretion of estrogen, progesterone, and testosterone will increase significantly. However, there is not much difference in the secretion of these hormones regardless of whether the baby is a boy or a girl. Moreover, the skin condition of pregnant women is also related to many factors such as living habits and environment. Therefore, it is not reliable to judge the gender of the baby based on changes in the pregnant woman's appearance and skin.

Symptom 3: Changes in taste during pregnancy

"Sour boy, spicy girl" is one of the most widely circulated rumors about whether to give birth to a boy or a girl. If a pregnant woman likes to eat sour food, she will give birth to a boy, and if she likes to eat spicy food, she will give birth to a girl. Moreover, pregnant women carrying boys have a big appetite and eat a lot of their favorite foods.

Comment: After pregnancy, the hormonal environment in the pregnant woman's body changes, including stomach acid and taste bud secretions, so it is normal for pregnant women to have changes in taste. Especially in the early stages of pregnancy, many pregnant women will experience morning sickness, which can easily affect their appetite and make their dietary preferences different, which has nothing to do with whether they will have a boy or a girl.

Symptom 4: Fetal heart rate

It is generally believed that if the fetal heart rate is stronger and slower, the fetus is more likely to be a boy; otherwise, it is a girl (a more common way to guess the symptoms of a boy or girl).

Comment: In fact, girls' heart rate is higher than boys', but this is only the case when they are just born. When they are still fetuses, there is no difference in the heart rate of male and female fetuses. During pregnancy, the fetal heart rate varies with gestational age. Generally speaking, at 5 weeks of pregnancy, the fetus' heart rate is close to the mother's heart rate, 80-85 beats/minute. By the 9th week of pregnancy, the fetal heart rate gradually increases to 170-200 beats/minute. In the second trimester, the rate gradually slows down to 120-160 beats per minute. The speed of the fetal heart rate has nothing to do with whether the baby is a boy or a girl.
