Who decides the sex of the fetus?

Who decides the sex of the fetus? The social harm of illegal identification of fetal sex mainly lies in: causing serious imbalance between male and female ratio, hindering the healthy development of population, causing family conflicts, thus undermining social order and harmony. Who decides the sex of the fetus?

Who decides the sex of the fetus? 1 The prospective father decides the sex of the fetus.

Before the fertilized egg is produced, countless sperm will run like a race, hoping that the first sperm to enter the egg will become the embryo that breeds the fetus. The sex of the fetus depends on the nature of the chromosome contained in the most dynamic sperm that eventually combines with the egg to form a fertilized egg. Because the expression state of the egg contains X chromosome, the nature of the chromosome carried by the sperm entering the egg determines the gender of the expectant mother who finally gives birth to the fetus. If combined into a double X chromosome, it means that the expectant mother is pregnant with a female baby. If combined into a male treasure, then the expectant mother is pregnant with a male treasure. Therefore, the sex of the fetus is determined by the sperm in the prospective father.

The chances of having a boy are the same as those of having a girl.

The sex of fetus is determined by sex chromosome. There is only one sex chromosome in human cells, and there are two forms of expression, namely X chromosome and Y chromosome. The expression form of sex chromosome with female fetus is two identical XX chromosomes, and the expression form of sex chromosome with male fetus is XY chromosome. At the time of conception, the combination of sperm and egg is uncertain, that is, it is possible to form XX chromosome and XY chromosome. These two results are 50-50, so the chances of expectant mothers having boys and girls are the same.

The sex of the fetus is determined at conception.

The sex of the fetus is doomed when the fertilized egg is formed, and it cannot be changed in the later stage. Old people at home will calculate the expected date of delivery of the fetus to guess the sex of the fetus. There is even a saying that the fetus will be born at the beginning or end of the month, and the gender will be different. This is obviously unscientific. How to judge gender according to whether the fetus was born at the beginning or end of the month? It's not scientific to think about it. There is also a saying that the sex of the fetus can be changed during pregnancy, and changing the sex of the fetus depends on a specific drug. This statement is not only unscientific, but also extremely absurd, which may bring permanent harm to the development of the fetus.

Who decides the sex of the fetus? It is illegal to identify the sex of a fetus.

Main contents of new regulations on fetal sex identification

Article 2 of the Provisions on Prohibition of Fetal Sex Identification for Non-medical Needs and Sex-selective Artificial Termination of Pregnancy clearly stipulates that it is forbidden for any unit or individual to carry out Fetal Sex Identification for Non-medical Needs and Sex-selective Artificial Termination of Pregnancy. It is forbidden for any unit or individual to introduce or organize pregnant women to carry out fetal sex identification for non-medical needs and to choose sex for artificial termination of pregnancy.

Punishment for identifying the sex of the fetus

It is clear in the new regulations that the administrative department of health and family planning at or above the county level shall order the introduction and organization of pregnant women for fetal sex identification for non-medical needs and sex selection for artificial termination of pregnancy to make corrections and give a warning; If the circumstances are serious, the illegal income shall be confiscated and a fine ranging from 5,000 yuan to 30,000 yuan shall be imposed. Medical device production and operation enterprises that sell medical devices such as ultrasonic diagnostic apparatus and special equipment for chromosome detection to institutions or individuals without purchasing qualifications shall be ordered by the food and drug supervision department at or above the county level to make corrections and be fined 1000 yuan to 30,000 yuan.

Establish a departmental cooperation mechanism

The responsibilities of health and family planning, industrial and commercial administration, food and drug supervision and other departments were stipulated, and a cooperative mechanism and a joint law enforcement mechanism for investigating and handling "two non-behaviors" were established.

Management system of medical devices such as drugs for termination of pregnancy and ultrasonic diagnostic apparatus.

To implement catalogue management of drugs for termination of pregnancy, establish a registration system for the sale, purchase and use of drugs for termination of pregnancy, and prohibit pharmaceutical retail enterprises from selling drugs for termination of pregnancy. Establish medical device sales enterprises to sell medical devices such as ultrasonic diagnostic equipment and special equipment for chromosome detection, as well as the qualification examination and purchase and sale record system for medical and health institutions, teaching and scientific research institutions to purchase corresponding medical devices.

Responsibilities of the administrative department of health and family planning at or above the county level

(1) Responsible for supervising, organizing and coordinating the sex identification of non-medical fetus and the investigation and handling of sex-selective artificial termination of pregnancy;

(two) to be responsible for the practice access of medical and health institutions and their employees, the supervision of the use of related medical devices, and the publicity and training of relevant laws, regulations and practice norms;

(three) responsible for the use and management of the population information management system, and guiding the medical and health institutions to timely and accurately enter the relevant information such as the birth and death of newborns;

(4) Other matters stipulated by laws and regulations involving fetal sex identification for non-medical needs and sex-selective artificial termination of pregnancy.

Who decides the sex of the fetus? 3 months can tell the sex of the fetus. We can judge when we are pregnant by looking at the information of B-ultrasound, although the state stipulates that doctors can't tell pregnant women the sex of their babies. Generally speaking, the data on the B-ultrasound list will have correlation coefficients such as biparietal diameter, abdominal circumference, femur length, fetal sac, fetal heart rate, etc. You can know the sex of the baby by looking at the gestational sac. If you look at the B-ultrasound list of 40-50 days pregnant, if you see that the gestational sac is oval or round, it is a female baby, then the long strip is a male baby.

In general, people will distinguish between men and women by looking at the genitals of the fetus. At this time, it takes 4 months to judge. You can usually see it on a 5-month B-ultrasound. Experts say that the accuracy of three-dimensional B-ultrasound will be higher. Because sometimes when doing three-dimensional B-ultrasound, the baby may block it with his hand because he can't see it. To be precise, it is more accurate to look at the sex of the fetus at eight months.

Many people also have different views on the factors that affect the baby's sex. Generally, it has genetic influence, and boys and girls tend to have family tendencies. There is also the influence of acid-base environment. Because Y sperm is alkali-resistant and acid-resistant, Y sperm will be more active in alkaline environment, so it is easier to combine. X sperm is more active in acidic environment, so it is easier to fertilize. According to the principle of biology, XY is a boy and XX is a girl.

When can we decide something else?

In fact, at the moment when sperm and eggs meet, the baby's sex is already doomed. Before the combination, there was only one egg, but there were thousands of sperm. Only the strongest and fastest sperm can combine with eggs. When combined, half of the father's DNA and half of the mother's DNA will form a new set of genes, in which the father's DNA will be divided into two different genes, X and Y. If the sperm carrying X gene is combined with the egg, it will be a female baby, and vice versa.
