What is the difference between a boy and a girl developing in the womb

There are two genders in one ****, and there is a 50% chance that any of them will be correct. ...... Expert's word: The heart rate of a girl is higher than that of a boy, and this is true only at the time of birth, and there is no difference in the heart rate of a fetus between a boy and a girl. The speed of the heart rate only varies with the age of the fetus. At about 5 weeks of pregnancy, the fetus's heart rate is close to the mother's, which is 80-85 beats per minute. Then the heart rate gradually increases to 170-200 beats/minute by 9 weeks of pregnancy. Then it gradually slows down to 120~160 beats/min during the mid-pregnancy period. There are some misconceptions: Suggestion 1: Fetal heart rate is lower than 140 beats / min, then the fetus is a boy Expert statement: the girl heart rate is higher than the boy, this is only at the time of birth is right, the fetal heart rate on the boy and the girl does not have any difference between. There is no difference in heart rate between boys and girls. The speed of the heart rate varies only with the age of the fetus. At about 5 weeks of pregnancy, the fetus's heart rate is close to the mother's, which is 80-85 beats per minute. Then the heart rate gradually increases to 170-200 beats/minute by 9 weeks of pregnancy. Then to the mid-pregnancy period of time and gradually slowed down to 120 ~ 160 times / min. Saying two: pregnant women abdomen protrudes too large is a girl, the abdomen is not too protruding or the lower abdomen protrudes for the boy expert statement: if the pregnant woman's upper body is short, the fetus can only be extended outward, so the abdomen will appear to be very large. On the contrary, the pregnant woman's upper body is long, can provide enough space for the development of the fetus, the abdomen does not have to protrude outward. Saying three: pregnant women lower pregnant (lower abdomen is large) is a boy, upper pregnant (upper abdomen is large) is a girl Expert statement: If a pregnant woman is upper pregnant, it may be the first pregnancy or the pregnant woman's body shape is good. When a pregnant woman after a pregnancy, abdominal muscle relaxation, again pregnant with the natural "sagging". Saying four: nipple black is a boy expert statement: nipple color is affected by the body's hormones, progesterone and stimulate melanin cells in the body during pregnancy to increase the level of hormones, resulting in the surface of the body of some of the original black parts of the darker, when the child is born after the child will soon be restored, this phenomenon has nothing to do with the sex of the fetus. Saying five: eat acid and alkaline relationship with the birth of a boy or girl Expert statement: some people only rely on the taste to determine whether the food is acidic or alkaline, which in itself is a kind of misperception. It is important to emphasize that the human body acid-base imbalance state, usually due to illness. Statement 6: The morning of the birth of a girl? Expert statement: A survey of 5,900 pregnant women who were hospitalized because of severe morning sickness in early pregnancy found that 56% of these women gave birth to female babies and 44% to male babies. However, in the middle and late stages of pregnancy, the sex ratio of babies is similar to the normal distribution of pregnant women with severe ecstasy. Saying seven: the doctor opened the secret recipe for boys and girls "random wish" The doctor opened the "five secret recipes": "First, call the pregnant woman to sleep on the left side of the body, because the third trimester of pregnancy when the child has not fallen on the uterine wall, this method is very necessary, the male left and female. method is very necessary, male left female right you know, that is to say to the left side of the bed to give birth to boys, to the right side of the bed to give birth to girls." "Secondly, put an axe under the pregnant woman's bed, remember, with the mouth of the axe pointing upwards, and never touch it after you have put it there. This we did test, originally we put a piece of iron under a chicken nest, the result was that all the chickens hatched out were roosters." "Third, get a rooster, pluck the three longest hairs from its tail, and put them under the pregnant woman's bedclothes, along with her husband's nails and hair, wrapped in a red cloth." "Fourth, you must not eat meat, but only coarse food. Eating vegetarian food gives birth to sons, eating meat gives birth to daughters, and this has been the case since ancient times, so think carefully if this is true." "Fifth, the direction of the head of the bed when sleeping is also very important." Experts say: "The birth of a boy or girl is a chromosomal decision, the pregnant woman is pregnant, the sex of the fetus is decided, which can be changed at will? This is completely against science!" Saying eight: early pregnancy reaction will love to eat hot and sour "sour children spicy women" expert argument: "sour children spicy women" argument is no scientific basis. Medically speaking, the birth of a boy or a girl is mainly determined by the chromosomes, the mother's body in the eggs are with the X chromosome, while the sperm is contained in the X or Y chromosome, if the sperm into the egg is with the X chromosome, is a girl; if the sperm into the egg is with the Y chromosome, is a boy. So whether you have a boy or a girl is actually determined by the father. In a certain sense, the birth of a boy or a girl is related to the fertilization environment of the fertilized egg, that is to say, it is related to the environment around the fallopian tube.
