When a representative of the weaker sex receives a positive response from a pregnancy test, she has a number of questions and doubts. So, a woman thinks about how quickly her tummy will grow. The future mother is interested in her own well-being. Another important issue that worries a woman is the sex of the future baby. Is a boy or girl born? This article will tell you about how sex is determined by the fetal heartbeat. You will learn the features of the rhythm of muscle contractions in boys and girls. It is also worth saying that the sex of the child by the heartbeat at 12 weeks is determined more accurately than sooner or later.
Child gender: general description of the formation
At the time of fertilization of the egg, only one sperm penetrates into its cavity. It can carry sex gametes with an X or Y chromosome. Accordingly, the sex of the future baby is laid already at this moment. The embryo in this period has not yet fully formed, and you can not determine its gender.
At about 8 weeks of gestation , reproductive organs begin to form. In girls and boys at this moment they look the same. However, a strong transformation will take place in the future, and completely distinct genitals will appear.
Determining the sex of the child by the heartbeat in the womb
To begin with, it is worth saying what values exist, and how this affects the baby's gender.
The frequency of contractions. It is believed that in boys, the heart beats about 140 times per minute. Girls have more frequent contractions. So, the muscle of the future baby can make from 140 to 160 beats per minute.
The rhythm of contractions. Boys boast a measured and clear rhythm. Their heart beats smoothly and evenly. In future girls, the muscle contracts chaotically and excitedly. One gets the impression that the girls, even in the womb, are more emotional personalities.
Dependence on maternal heart rate. It is believed that a boyish heart beats not only clearly and monotonously, but also much louder. Also, all contractions coincide with the mother's pulse. Girls have no dependence on the beating of the heart of the parent. The tones of contractions in the muscles of future daughters are more muffled and less clear.
Side of the abdomen. There is a version that a boy’s heart beats on the left. If the sound comes from the right, then most likely a girl will be born.
Determining the sex of a child by heartbeat: true or myth?
Is it possible to believe the above regularity? Many couples use this method to find out who they will be born as soon as possible. However, the probability of a correct answer is only 50%.
Doctors say that research in this way is nothing more than simple entertainment. Officially, such a technique is not recognized and does not have any reasonable evidence.
How can I calculate my heart rate?
So, you already know how to determine the sex of the child by heartbeat. The options proposed above can be grouped and combined with each other. However, to make any conclusion, you must first calculate the heart rate of the baby in the womb. This manipulation can be carried out in several ways:
- with a stethoscope (this option is suitable for measurements after 12 weeks of pregnancy, when the reproductive organ leaves the borders of the small pelvis);
- using a tube (this method is used after 20 weeks of pregnancy, when the fetus is already quite large);
- cardiotocography apparatus (research and measurements are made after 30 weeks of pregnancy);
- using doppler (the device is used after 15 weeks of development of the child and resembles a miniature ultrasound machine);
- during ultrasound (diagnosis can be carried out in the very early stages of pregnancy).
How to determine the gender of the crumbs in 12 weeks?
If you want to know the sex of the child by the heartbeat at 12 weeks, then you need to conduct an ultrasound scan. During diagnostics, a specialist can turn on the sound of the device. This will not only calculate the number of contractions, but also hear them.
Also, the doctor can display the curved line of the cardiogram. A special program measures and counts heartbeats. The operation of the technique avoids the error that could have been when counting strokes by a person. So, how to determine the sex of the child by the heartbeat at 12 weeks?
What is typical for girls? During this period, the frequency of muscle contractions is in the range from 150 to 170 beats per minute. Knocks are fast and muffled. The rhythm is chaotic, and it’s hard for you to catch the monotony. Also, an experienced specialist may have their own ways to determine the gender of the baby by the beat of his heart.
What is typical for boys? Heartbeat is observed from 120 to 140 times per minute. The sound produced is clear and loud. The contractions are more like an adult heartbeat. The special rhythm is also determined. With increased pressure or excitement of the mother, the baby's heart begins to beat faster. This pattern is present in most cases.
Summary and short conclusion
So, now you know how to determine the sex of the child by the heartbeat at 12 weeks. Remember that with an increase in the term, the number of muscle contractions gradually decreases. By the time of birth, it reaches 100-120 beats per minute.
Also, taking measurements too early can lead to an erroneous result. In the period from 8 to 10 weeks of the baby's development, his heart can beat with a frequency of up to 180 beats per minute. At the same time, boys are practically no different from girls.
Remember that an ultrasound examination that is carried out after 20 weeks of pregnancy will help to more accurately find out the gender of the unborn baby . That is why you should not be too trustful of all methods of early diagnosis of a child’s gender. I wish you success and the birth of healthy children!
