Type of fetus
The sex of the next child is a mystery since ancient times; parents try to determine it prematurely. The pregnant woman often begins to think about the sex of the fetus as soon as she is pregnant, and perhaps much earlier. There are many beliefs about how to determine the sex of the fetus, By his prenatal sex.
According to genetics, it is the man who determines the sex of the fetus; the chromosomal model of the man is XY; that is, half of the sperm produced by female chromosomes (X), while the remaining sperm carry the male chromosome (Y) (X). If the egg (X) is fertilized with an X chromosome, an embryo carrying the chromosome (XX) will be produced; ie, a female. If the egg is fertilized with a spermatic cell, The chromosome carries the Y chromosome And Sumi (XY); no mention.
Development of the fetal genitals
The development of the fetus’s genitals takes place around the seventh week. The testis and ovary are formed in the abdominal cavity. The external genitalia in this period are similar in both males and females. At about the ninth week, gender differences appear. For females, a small bud emerges from the tissues of the legs , And then develops into the bud of the clitoris, and then separate the membrane, which forms under the sprout form the small labia, vaginal opening, and before the fetus reaches the age of twenty-two weeks, complete the formation of ovaries, and moves from the abdomen to the basin, A ovarian nearly six million primary oocyte.
In males, the bud develops into the penis and begins to elongate in the twelfth week. The outer membrane grows, and the scrotum, which will later be surrounded by the testicles, and before the 22nd week of pregnancy, complete the testicles, which contain immature sperm in the abdomen, The testicles then begin to gradually descend into the scrotum, but they take a long time to reach their destination in late pregnancy, sometimes after birth.
Determination of fetal sex
The doctor will not be able to distinguish the sex of the fetus when examined using sonar or ultrasound before the fourteenth week, after which the doctor is supposed to be able to distinguish the sex of the fetus if its position in the uterus allows the doctor to see the genitals, The fetus sex can be detected using a range of tests including:
- Blood test for Down Syndrome (NIPT): This test is performed from the 10th week and is mainly intended to detect the presence of some chromosomal disorders, such as: Down syndrome, but it also reveals the sex of the fetus.
- Amniotic fluid examination: This test can be done between the 16th and 20th weeks of pregnancy to determine if the child has a genetic disorder, chromosomal anomalies such as Down Syndrome and the detection of the fetus.
- Checking the placenta of the placenta (CVS): This test is similar to the amniotic fluid test, but can be performed between the 10th and 13th weeks of pregnancy.
- DNA tests: This test can be performed during the ninth week of pregnancy and is intended to detect possible genetic abnormalities, but it can detect the presence of the chromosome (Y) which indicates that the fetus is male, and the accuracy of this test is 100%.
Predicting the sex of the fetus by popular methods
There are many myths and popular ways to predict the sex of the fetus, and you may find a great conflict between them; some may explain a certain phenomenon that the mother is pregnant with a female, while others interpret as pregnant male, and one of the most popular ways to predict the fetus popular spread as follows:
- Moving a Ring Hanging with a Chain Often the wedding ring is in front of the pregnant woman’s belly. If the ring swings back and forth like a pendulum, it means that the fetus is male, but if a circular motion moves, it is female.
- If the number of fetal heart beats between 110-130 per minute, the fetus is male, but if it is between 140-160 fetal fetus.
- The line of the dark line formed in the middle of the belly of the carrier (Linea Nigra); if the line extends from the pelvic area to the navel only, the fetus is female, but if extended towards the bone of the shear will be male.
- Drano is tested, where the liquid is mixed with the pregnant woman’s urine. If it turns brown, the fetus is female. If the color is green, it is a male.
- If the pregnant woman looks more beautiful, she is pregnant with a male, but if she looks less beautiful than usual, she is pregnant with a female.
- If the belly of the pregnant woman is low and forward, the fetus will be female, but if the abdomen is high and round, it will be male, and doctors think that the shape of the pregnant belly depends on the position of the abdominal muscles and the position of the fetus.
- If the pregnant woman feels a great desire to eat sweets, the fetus is male, while if she has appetite for sour foods, she will be a female. Doctors believe that the appetite of the pregnant woman changes according to hormone changes.
- If the pregnant woman suffers from nausea in the morning, the fetus is female.
- The use of the Chinese table to predict the sex of the fetus. Some websites have a calculator that can predict the sex of the fetus, depending on the age of the Chinese lunar pregnant woman at the time of pregnancy and the Chinese lunar month in which the pregnancy took place. All the mother has to do is enter the date of fertilization , Then her age will calculate the lunar age of China, and predict the sex of the fetus.
Choosing the sex of the fetus
Some families want to control the sex of the fetus for a variety of reasons, including: balancing males and females, preventing their children from inheriting genetic diseases associated with sex, and methods used to determine the sex of the fetus before pregnancy:
- Timing of sexual intercourse to determine the sex of the baby: The male sperm is characterized by light weight, speed of movement, but lived for a short period of time, while female sperm is characterized by weight and slow movement, but it lives If the couple wants a male child it is recommended that intercourse occurs immediately after ovulation, so that the male sperm reaches the egg before the slow female sperm. When the couple wants to have a female, it is recommended that intercourse occurs two to four days before ovulation. In which ovulation will occur most active sperm female sperm, after the death of most of the male sperm short-lived, and the effectiveness of this method is up to almost 75%, but some doctors question the effectiveness of this method.
- Dietary diets: This increases the sodium and potassium content of the food and decreases the calcium and magnesium content. This changes the receptors on the wall of the egg to become more attractive to the male sperm carrying the chromosome (Y). (X). Thus, the result of vaccination is male, and the opposite occurs when calcium and magnesium are increased in the blood, and sodium and potassium decrease. The sperm of the male chromosome (Y), the result of vaccination and female pregnancy. To take advantage of this method, the woman must adhere to a diet for at least two months before pregnancy to support the food stock that promotes the desired sex.
- Artificial Vaccination: This method is based on the separation of sperm (X) and sperm (Y) using laser light, pigments, flow cytometry, and after separation of sperm, injected sperm desired in the body of the wife, and success rate of this method up to 91% between couples Wishing to have a female, and 73% for those who want to have a male.
- Control of pH: The use of this method increases the birth rate of a male child by 5%. It is based on the knowledge that the acidic medium is suitable for the female sperm, that the basal medium is suitable for the male sperm, and the pH can be controlled by taking acidic or basal vaginal douches; .
- IVF Children: In vitro fertilization begins by giving the wife fertility drugs to stimulate the ovary to produce more than one egg. The doctor then inserts a thin needle through the vaginal wall to extract the eggs. The eggs are then fertilized with the sperm in a petri dish and after 3-5 days, The doctor then injects the desired embryos into the uterus by inserting a thin tube through the vagina and cervix.
