Fetation week six of pregnancy

The dimensions of the fetus

On the sixth week of pregnancy, the embryo size is 12 mm, for the week fetus doubled.

Brain

Intensively developing brain, head size is larger than the body. The impact of unfavorable factors at this time can lead to deviations in the sexual differentiation of the brain, which in the future can change a person’s sexual orientation. Growing amniotic cavity in which fluid accumulates and it floats freely embryo, making his first movement.

Sex of the child

At 6 weeks of gestation there is a differentiation of fetal sex — if there is no Y-chromosome, it will be a girl, and developing ovary.

Depending on the sex of the fetus begin to form the seminal vesicles, vas deferens, or ovaries. Formation of female genital mutilation takes place against the background of maternal estrogen content.

At the end of the fifth — the beginning of the sixth week of fetal male testes begin to synthesize testosterone. This hormone is the main androgen and has a direct stimulation of the vas deferens. Acting on the urogenital area fetal testosterone creates external genitalia. Formed the prostate, testes, seminal vesicles On the contrary, the lack of male hormone leads to the development of the female phenotype.

Hormonal disorders, women may result in the formation of uterine abnormalities in the fetus. Which can lead to the formation of the male fetus with female characteristics (female karyotype) or female fetus with male characteristics (male karyotype). Genetic mutations in this week may lead to further changes in the child’s sexual orientation.

Nervous system

On the sixth week continues the rapid development of the nervous system. Brain and spinal cord begin to separate a, complicated structure of nerve cells begin to differentiate the cerebellum. At this period the embryo can already bend and straighten the neck and head to flick to the sides.

Already beginning to emerge facial features. Limbs become characteristic differences appear fingers. In the hands of the embryo appear wrist and elbow area.

Nutrition

Intensive development of the fetal nervous system requires the introduction in the diet of pregnant women foods rich in B vitamins vegetables, dairy products, plums, cherries, potatoes affect the synthesis of coenzyme, which is involved in tissue respiration.

Carbohydrates, phosphorus and calcium

Products from wheat flour, fish, eggs are important in the regulation of carbohydrate and energy metabolism and the formation of connective tissue. Important components in the diet of women at this stage are phosphorus and calcium contained in an optimum ratio in cheese and milk.

Ultrasound at six weeks

Ultrasound specified period of pregnancy, the fertilized egg takes half the volume of the uterus, thickening chorionic seen in the place where then will form the placenta. Yolk sac — 0.4 cm. The heart rate of 140-160 beats / min, with the threat of termination symptoms (abdominal pain, bleeding) clarifies the presence retrochorial hematoma and its size.
