The seventh week of pregnancy from conception corresponds to the ninth week obstetric (obstetricians count pregnancy term on the first day of the last menstrual period). The seventh week, like all previous ones, plays an important role during pregnancy and child development.

Development of the embryo in the seventh week

On the seventh week of pregnancy and continues all the growth and development of the embryo.

Continue to develop internal organs and systems in the brain is formed by the cerebellum, which is responsible for the coordination of movements, and the pituitary gland, which subsequently begin to produce hormones. Formed adrenal cortex, responsible for the production of adrenaline, formed the lymph nodes, which will soon begin to produce defense cells - lymphocytes, begin laying genital and pectoral muscles.

  Thanks to advances in modern medicine infertility problem no longer seems so intractable as a few years ago. Existing IVF or in vitro fertilization (from the Latin words "extra" - the appearance on the outside and the "body" - the body) provides several options that allow the family to get a long-awaited child.

IVF is necessary in cases where there is a serious uterine pathology, functional failure of vital organs (heart, liver, kidney), especially in the stage of decompensation in women or sperm, disturbance of men. Sometimes the reasons for the lack of pregnancy remain unclear, but if the couple during the year, despite regular attempts, there is no conception, then it is also recommended to resort to using the program.

Unfortunately, many couples have not yet resolved to take the help of in vitro fertilization, both objective and subjective reasons. By objective reason is the high cost of services. Indeed, similar manipulations in some clinics are sometimes estimated to twenty thousand dollars, for many couples is not available price. Especially when you consider that the cost of services is paid regardless of the outcome, that is one hundred percent no one can guarantee. And warn spouses about this in advance.

But even if the price is not an obstacle, many people confuse the fact of artificial insemination, especially when using a sperm donor. Other subjective reasons is the stubborn belief that artificially conceived children will not be able in the future to give birth to her own child. This conclusion is not under a completely no reason, because the conception of a child is exactly the same as for natural fertilization, ie, by the merger of male and female sex cells. The only difference is that the merger is carried out outside the mother's womb. But for the further development of the embryo germ cells a venue plays absolutely no role in the future and confirmed the emergence of a healthy offspring from the so-called "people out of the tube."

How, then, carried out in vitro fertilization? Primarily follikuloobrazuyuschuyu stimulate ovarian function. Because of this, several mature eggs, and increases the chance of pregnancy. Next is the puncture of the ovary with the purpose of the fence mature eggs. Do not be afraid of this procedure - it is non-traumatic, and virtually painless. For its conduct does not even require hospitalization. At the request of the patient and the procedure can take place under local anesthesia, although it is likely to reassure the patient.

Once transferred to puncture the egg cups with special nutrient medium, which is placed in inkubature, which has created the most identical conditions of intrauterine development. Thus, in an incubator maintained at a constant temperature, the gas composition is controlled by air and so on.

After five or six hours in a cup made with eggs gently sperm. The result is a fertilization cell division, which is fixed by means of microscopic examination. After 2-3 days the embryo is transferred into the natural fetal condition, where continues its development. The process of moving the embryo in the uterus also completely painless.

A few days later to confirm the pregnancy blood test Blood tests: a mirror of health   the presence of specific hormones in pregnant women. Three weeks after the beginning of the development of the embryo is detected by ultrasound.

Another option of IVF, which can be applied in the complete inability of women to nurturing the child acts surrogacy program. This woman bears and gives birth to the child, not being his biological mother. When male infertility The causes of infertility - heredity and lifestyle   may use donor sperm. The health status of the donor, including genetic predisposition to various diseases, is strictly controlled, and the couple can get acquainted with external data and other characteristics of the donor and pick it yourself.
