Rh factor of the fetus
During pregnancy, the thoughts of future parents are focused on the child. Many, burning with impatience, rush to get acquainted with all sorts of ways to calculate the sex of their heir. The desire to learn at any cost, boy or girl, obliges to analyze known methods: from scientific medical to handicraft folk.
The obsessive interest of young couples to this issue allows you to predict the sex of the baby before he is born. Practice of application of expedient methods convinces in high probability of result.
In what ways can you determine the sex of the child before it is born?
To date, the most accurate way to determine the sex of the child before his birth is ultrasound. To see the child’s genitals on examination is only possible from the sixteenth week after conception. In addition, the purpose of ultrasound is not to find out the sex of the child, but to identify whether there is a threat of pregnancy.
This means miscarriages or chromosomal abnormalities. Especially relevant is the examination, if the patient has a history of miscarriages or abortions.
Although they take as prescribed by the doctor morning care when planning the birth of a baby, yet, as the first weeks from the moment of conception proceed, it is necessary to track.
Many medical institutions are working on determining the sex of the child hormonal method, measuring the amount of human hormone chorionic gonadotropin in the blood. Although many researchers argue that the presence of a hormone helps determine the sex, this way can only confirm the presence of pregnancy.
It is not ruled out that the expediency of the methodology will be proved in the near future.
Since the discovery of a new antigen in the human erythrocytes, called the Rh factor, the scientist has become clear why the blood of the mother and the fetus sometimes has a rhesus-conflict. This can occur if the mother’s rhesus is negative, and the father is positive. Erythrocytes containing a positive Rh factor of the fetus (from the father) penetrate the placenta into the mother’s blood and produce antibodies in her body that, when ingested in the baby’s blood, destroy its erythrocytes.
Between the blood of the mother and the blood of the baby there is a rhesus-conflict, which can result in the death of the embryo or the birth of a baby with anemia, jaundice, dropsy or swelling. Moreover, pathology manifests itself in the second and subsequent pregnancies, as the blood flow of the mother and child is mixed only during labor.
The likelihood of an unfavorable outcome increases with each pregnancy, and abortion, preceding the current interesting situation, likewise acts.
Since the Rh factor is formed in the child from the eighth week, from the same period, we can expect a rhesus-conflict between the mother and the fetus. Therefore, all pregnant women in the consultation do the analysis for Rh.
