Acne on the back during pregnancy means it's a boy

Pregnancy is very important to the family, especially for female friends during pregnancy. People are concerned about whether the baby is a boy or a girl. They usually judge the gender of the fetus from many aspects of the pregnant woman's body. So, if there are pimples on the back during pregnancy, is it a boy or a girl?

If I have pimples on my back during pregnancy, is it a boy or a girl?

The appearance of pimples on the back during pregnancy has little to do with whether you are having a boy or a girl. Whether a boy or girl is born is not determined by women, but mainly by the chromosomes of men.

Chromosomes, to put it simply, are the basic sex chromosomes. In human somatic cells, there are 23 pairs, or 46 sex chromosomes, of which 22 pairs are autosomes and 1 pair is chromosomes. Women's chromosomes are XX, and the genotype can be expressed as 46,XX. The male's sex coloration is XY, and the genotype is 46, XY. Somatic cells undergo two rounds of meiosis, and the 23 pairs of sex chromosomes become 23. The egg cell contains only one chromosome, X, while male sperm can contain either X or Y chromosomes.

When the male sperm and egg cell fuse, the sex chromosomes of the combined sperm and egg are repaired into 23 pairs. If a male sperm containing an X chromosome fuses with an egg cell, the sperm and egg will form an XX type, and the fetus will grow and develop into a female. If a male sperm containing a Y chromosome fuses with an egg cell, the sperm and egg will form an XY type and grow into a male fetus.

Therefore, whether a boy or girl is born depends on whether the sperm of the X male or the Y male is involved in the insemination. The fusion of sperm and egg is random and not determined by everyone's beliefs. This is the only way to maintain a rough balance in the proportion of the two sexes in the human body. This is also a kind of biological diversity in nature. This balance must not be destroyed, otherwise, it will inevitably lead to unpredictable social problems.

Know in advance if you will have a boy or girl

Early knowledge of whether to have a boy or girl:

1. If the fetal heart rate is less than 140 beats/minute, it is a boy. If it is higher than 140 times/minute, it is a girl. The truth: Girls have higher heart rates than boys, but this is only true right after birth. There is no difference between the heart rates of boys and girls in the fetus. The heart rate only changes with the gestational age. At about 5 weeks of pregnancy, the fetus' heartbeat is close to the parents' heart rate, which is 80-85 beats/minute. Then until the 9th week of pregnancy, the heart rate slowly increases to 170-200 beats/minute. Then during the second trimester it slowly slows down to 120-160 beats/minute.

2. Darkening nipples indicate a boy. The truth: Nipple color is affected by hormones in the body. During pregnancy, the body's corpus luteum and melanocyte-stimulating hormone increase, causing some originally dark areas on the body surface to become darker. These areas will quickly recover after delivery, and this phenomenon has nothing to do with the identification of the sex of the fetus.

3. The pregnant woman is expecting a boy in her heart and a girl in her tummy. The truth: If a pregnant woman is carrying an upper calf, it may be her first pregnancy or she may have a good figure. After a pregnant woman has been pregnant once, her abdominal muscles become weak, and of course they become "loose" when she becomes pregnant again.

4. The relationship between eating sour or alkaline foods and whether the baby is a boy or a girl. The truth: Many people judge whether a food is acidic or alkaline based on its taste, which is a wrong idea in itself. It should be noted that an imbalance of strong acids and alkalis in the body is usually caused by illness.
