Child's sex: general description of the formation
At the time of fertilization, only one spermatozoon penetrates into its cavity. It can carry sex gametes with the X or Y chromosome. Accordingly, the sex of the future baby is laid already at this moment. The embryo was not completely formed at that time, and you can not determine its sex.
About 8 weeks of pregnancy reproductive organs begin to form. At the moment girls and boys look the same. However, in the future there will be a strong transformation, and absolutely distinct genitals will appear.
Determining the sex of the baby by heartbeat in the womb
To begin with it is necessary to say what values exist, and how this affects the sex of the baby.
Frequency of abbreviations. It is generally accepted that boys have heart knocks about 140 times a minute. Girls have more frequent contractions. So, the muscle of the future baby can make from 140 to 160 beats per minute.
Rhythm of contractions. Boys can boast a measured and clear rhythm. Their heart beats smoothly and evenly. In future girls the muscle is reduced chaotically and emotionally. It seems that the girls are still more emotional in their mother's womb.
Dependence on the maternal pulse. There is an opinion that the boy's heart is beating not only clearly and monotonously, but also much louder. Also, all abbreviations coincide with the mother's pulse. Girls do not have any dependence on the knock of the heart of the parent. The tones of muscle contractions of future daughters are more muted and not so clear.
Side of the abdomen. There is a version that the boy's heart is beating on the left. If the sound comes from the right, then most likely a girl will be born.

- using a tube (this method is used after 20 weeks of pregnancy, when the fetus is already quite large);
- cardiotocography apparatus (examination and measurements are made after 30 weeks of pregnancy);
- with the help of Doppler (the device is used after 15 weeks of child development and looks like a miniature ultrasound machine);
- during ultrasound (diagnosis can be carried out at the earliest stages of pregnancy).

What is typical for girls? During this period, the frequency of muscle contractions is in the range of 150 to 170 beats per minute. The knocks are quick and muffled.

Summing up and a small conclusion

That's why do not be too gullible to treat all methods of early diagnosis of the sex of the child. Good luck to you and the birth of healthy babies!
