Bayi Tabung / in vitro fertilization

In-vitro fertilization or IVF is a technological advances in the medical field in response to the alarming rate of infertility in developed countries. The concept was launched by Patrick Steptoe and Robert Edwards, a physiologist at Cambridge in the late 1960's and a decade later, the first IVF baby was delivered in the UK.

IVF was invented mainly to help women who suffer from infertility due to blocked fallopian tubes or uterine sick, but over time, the procedure has been extended to cover cases such as endometriosis, cervical mucus hostile and a host of other infertility problems. It is even now applied in cases where the husband or male partner suffers from a low sperm count, but the results with them have not been particularly impressive.

The process of in vitro fertilization, for the most part, involves the use of a laparoscope, a telescope, which can be inserted into the abdomen of women under anesthetic conditions, to remove the eggs from the ovary in women of a period just before the time when it would naturally be released (Ovulé). Harvesting egg is then mixed with washed and diluted male sperm in a glass dish. If fertilization occurs between the egg and sperm, the resulting embryo is allowed to develop in the laboratory, usually for two to three days before the embryo is then implanted or reintegrated into the uterine cavity the woman with a kind of plastic tube.

Like any other man the procedure, the IVF has its own share of limitations and adverse effects. The success rate of the procedure and the risk of suffering an ectopic pregnancy, a pregnancy that implants and develops outside the uterus and can be found almost always broke with tube to the uterus, are two of these issues. Moreover, with IVF, pregnancy does not always guarantee the birth. Fake layers and ectopic pregnancy tend to be higher with this procedure compared to the general population. Losing the pregnancy of an IVF procedure is fairly common, but there is no overall estimate, while the occurrence of ectopic pregnancy from in vitro fertilization is estimated at 5-10% of all IVF pregnancies.

Another problem with in vitro fertilization is the success rate. The success for IVF procedures vary from one place to another, although no figure is considered high everywhere. For every two that the use of IVF and obtain a happy outcome, there are many couples who find their infertility intractable problem. This notwithstanding, the technological basis of IVF is improving day by day, that the facts are becoming clearer about IVF, which leads to better results with attempts at IVF, the figures quoted in most major IVF centers are, in this order: eight to ten per cent chance of pregnancy if only one embryo is implanted in the uterus of women, twenty percent chance if two embryos are implanted and thirty percent chance of being pregnant three embryos implanted. For medical reasons, the number of embryos implanted rarely exceeds three or four. However, it is imperative to reiterate here that pregnancy, as under normal conditions, does not always guarantee the birth.

In-vitro fertilization was a major breakthrough in the treatment of infertility in the past two decades. The procedure requires sophisticated technological equipment and a high level of skill on the part of medical operators. Despite the fact that doctors and others in the medical field can not make promises or guarantees on IVF again, it is clear that the procedure has put the joy on the faces of many couples and still holds hope for those awaiting her.
