When In Vitro Fertilization Should Be Done?

When In Vitro Fertilization Should Be Done?

The inability to raise a child is an idea that haunts any couple. And there are not a few who are affected by this difficulty. Data from the World Health Organization estimate that between 60 and 80 million people worldwide have some commitment to follow the maternity and paternity project. Since infertility affects 20% of couples of reproductive age. In Brazil, according to data from the last census, about 6.5 million couples have problems generating a child.

This difficulty can have several causes, male or female. In women, endometriosis is one of the main reasons. It is caused by an inflammatory condition due to endometrial cells that are not properly expelled during the menstrual period - clinging to other organs in the body - which leads to irregular bleeding and in many cases is responsible for miscarriages.

Problems in ovulation - usually caused by hormonal disorders - polycystic ovary syndrome and tubal obstruction are other factors responsible for female infertility. In men, however, varicocele in the testicles is the most common cause. It is characterized by varices in the inguinal cord, that is, an abnormal dilatation of the testicular veins that hinders the venous return provoking testicular dysfunction, worsening semen quality due to the warming of the testicles.

It is recommended that in cases if the couple is unable to perform fertilization after attempts in the course of a year without the use of contraceptive methods, it is necessary to seek the assistance of a specialist to make the diagnosis of the causes of infertility. In vitro fertilization (IVF) is a treatment that consists of fertilization outside the body, ie it is performed in an artificial environment. But precisely, after the definition of the beginning of treatment, the woman is subjected to ovarian stimulation. It is performed through injections daily - for the period of 10 to 12 days - in order to stimulate the woman to produce several eggs. After this process, the ova are aspirated through a surgical procedure and evaluated.

In the case of men, the spermatozoa are collected through masturbation. They also undergo analyzes to identify quality, quantity, and driveability. Given that, are the sperm cells placed together with the eggs? in a kind of incubator - for fertilization to occur naturally. The transfer of the embryo to the uterus occurs in the third after fertilization using a catheter.

When is the treatment necessary?

In 1978 the first baby was born by the technique of in vitro fertilization. Since then, millions of babies have been born worldwide with the aid of treatment. According to Anvisa data, in 2012, 93,320 embryos were produced and 21,074 cycles of in vitro fertilization were carried out in Brazil alone. In total, about 34,964 embryos were transferred to the woman's uterus. But in the United States, for example, over the past ten years the number of in vitro fertilization cycles has gone from 90,000 to 150,000. However, in contrast, the proportion of in vitro fertilization for tubal problems was reduced from 25% to 16% during the period between 2000 and 2010. These data are from a study conducted by the University of Amsterdam in the Netherlands in January 2014, which showed that many times the technique is done without necessity.

In view of this, it is important to emphasize that IVF was created as a treatment option for women who presented with disorders of the fallopian tube and men who were severely infertile. Through this, the risks of a pregnancy by natural methods are the same as one through IVF, which will ensure the effectiveness of the treatment are the characteristics and daily habits of the couple. In this case, treatment should be an option for couples who have not been able to fertilize after attempts by natural methods for a period of one year.
