Sonar
Sonar is an ultrasound device that sends high-frequency sound waves through a woman’s womb. These waves bounce back from the fetus, turning into a screen image showing the movements and position of the fetus in the mother’s womb. These waves are reflected by the solid tissues such as bones , And appear in the image in white color, and also reflected on the soft tissue and appear in gray, and liquids such as amniotic fluid amniotic appears in black, and the purpose of the use of this device is to know whether the fetus grows naturally or not.
Benefits of using a sonar scan
- Examines the heartbeat of the fetus.
- Indicates whether the pregnancy is with one or more children.
- Detects if the pregnancy is inside, or ectopic (in the fallopian tube).
- Shows any internal bleeding.
- The exact date of fertilization is determined by measuring the size of the fetus.
- The probability of the fetus being diagnosed with Down’s syndrome is measured by measuring the fluid behind the neck during the third and fourth month of pregnancy.
- Helps in some diagnostic tests; such as a sample of the placenta, or amniotic fluid.
- Characterizes congenital defects such as spinal cord.
- Measures the amniotic fluid level.
- Locate placenta.
- Measures fetal growth rate, its members.
How to know the sex of the fetus
If the child is in the wrong position, it may be difficult. If the system is developed to determine the sex of the fetus is possible during the third month of pregnancy, the normal organs do not show this until the fifth month; because the fetus members Nationality will be completed, and featured significantly.
The sex of the baby can be determined by observing the shape of the genitals. If the fetus is a female, three white lines appear on the screen, which is the opening of the vulva, and the two follicles that grow later after puberty to cover the opening. If the sex of the fetus is male, Clearly, if it is not clear, two cards will appear, the testicles instead of the white lines; the male genitalia appear in the shape of the tortoise. There is a false saying that when the penis appears, the fetus is male, but if it does not appear, sex is female.
Factors Affecting Gender Determination
- How to place an intrauterine fetus.
- Angle sonar photography.
- The weight of the mother, as the thick tissues in obese women affect the clarity of the image of the fetus.
- The bladder must be filled with urine; this helps the fluid to convey the image more clearly.
