To make short:

Eggs are collected with a syringe during a medical collection by the mother. The father have an easier time giving the sperm (no invasive procedure needed). The eggs and the sperm are then mixed togeteher in a test tube/cell culture dish in a medium that will provide the cells the good conditions to survive. When some embryosstart to develop (at a few cwlls stages) they are reinserted directly in the mother uterus to finish developing. Since all the eggs do not fixe themselves on the membrane to finsh their growth, and then get lost, or simply do not survive the transfer, there is usually more than one embryo reimplanted, hence the higher number of multiple birth (or the need of selective abortion) with in-vitro procedures.

Why do they put the embryo back in the mother? cant food, antibodies and oxygen be provided by other means? if yes then why do they still reimplant the embryo into the mother?

Or to answer more simply: No, there is more in growing than just feeding the right media. We still have to go the old way. The brave new world is not here yet.

As far as I know there are no differences in the look or in terms of medicaly measurable factors between baby born after in-vitro fertilization and the old way.

As I told you in my first post, the inserted embryos do not always get implanted in the uterus. Contrary to a kidney graft, this doesn't do anything to the mother (women can live without babies ;) ) but this is fatal for the embryo, who in the other hand cannot survive out of the mother. But even in the ols fashionned way the embryo do not always get implanted. You just don't know it, and the financial outcome is much lower considering the prices for IVF....

And this is not linked to tissue match, because since even in the good old way, the HLA system and the blood group do not need to necessarily match.

And beside the conception/reimplantation step, the rest of the pregnancy is exatly the same as if the baby was conceived he old fashionned way. once reimplanted successfuly the body do not make any difference between the embryos. Complications can be the same.

I heard that in-vitro-babies are much more disposited to certain illnesses (like cancer) than babies growing up the normal way are. There´s always a risk connected to IVF.

In simple Test Tube Baby are those when Egg taken from Woman and Sperm taken from MAle and the egg fertilized in a Tube by Technique IVF is known as Test Tube Baby.
Test Tube baby in India , Punjab is normal like other babies but they not fertilized in woman's body but the outside of body of woman in a tube.

1. What is IVF?

IVF is an abbreviation - stands for "ExtraCorporal Fertilization", i.e. fertilization outside the female body. Only the surrogate mother does not need to stimulation of the ovaries hormonally in order to get several eggs needed for fertilization. She is immediately transplanted already fertilized "in vitro" biological mother egg. At the same time, hormone replacement therapy is carried out to the surrogate mother. In addition, doctors should warn that, according to indications, a cesarean section is possible. Also, it is used for surrogacy.

2. The specification of the procedure

A man delivers sperm either on the day of the collection of the egg from the biological mother, or defrost previously frozen sperm. On the day of the collection (or defrosting) of the ovum, they are fertilized by sperm. There are two ways: either a portion of the sperm is added to each egg produced. Alternatively, one sperm cell is injected into the egg using a microsyringe. This method is called ICSI.

"Processed" eggs are left for a day in a special incubator. The next day, the cells are evaluated for the presence or absence of fertilization. The fertilized egg is nursed (as the doctors say - cultivated) in the incubator for an additional two or more days.

Embryos are transferred to the uterine cavity on the third or fifth day of their development. Usually, women under 38 years old transfer 2 embryos, over 38 years old - 3 embryos. The embryo transfer procedure does not require anesthesia. 12-14 days after the transfer, a pregnancy test is done to understand how successful the attempt was.

Moreover, the probability of successful fertilization and pregnancy is not great. Only 30-35 percent.

3. Until what age is egg sampling possible?

As doctors explain, with age, the number of healthy eggs decreases. And the sooner they are handed over for storage, the better - preferably up to 38 years. The older, the worse they freeze, and, accordingly, thawed. And worse fertilized. Although egg sampling is possible before menopause, that is, up to 50-60 years. Stored in a freezing egg, sperm, as well as embryos (already fertilized eggs) can long - in liquid nitrogen, in special conditions.

At the same time, sperm and embryos transfer frost very well. But with eggs earlier it was more difficult. The first child of a frozen egg, or rather, twins, was born in Australia in 1986. But then, in fact, until the mid-90s, frozen eggs defrosted very badly. Now, fortunately, completely different technologies, which allow the biomaterial to be preserved in very good condition, as much as necessary.

Test Tube baby procedure is also known as IVF. It is a very long procedure and is recommended by the doctor if other treatments don't seem to work. You need to visit a good IVF Doctor to learn about this procedure and if you can go for it or not. Visit this site to know detailed information about IVF.
