Each married couple who places greathopes for IVF, wants to get results on the first attempt. Such a probability does exist. On average, according to statistics, 50% of in vitro fertilization procedures are successful. However, the figure depends on many factors, such as the health status of men and women, so a competent approach to training and the professionalism of doctors. It is also necessary to take into account the natural component: even with natural fertilization, the probability of pregnancy is not 100%. Normally, a perfectly healthy woman can have menstrual cycles when immature follicles appear that can not function fully and form qualitative eggs that are capable of fertilization.
Let's consider in more detail what factors determine the positive result of IVF from the first time.
Age of expectant mother
Physiologically, the female body is designedway, that after the suppression of the turn of 35 years the number and quality of the reproductive cells begins to decrease. According to official data, natural pregnancy occurs depending on the age in the following cases:
Thus, it is better not to postpone the procedureECO, the more modern technology allows you to freeze the resulting eggs to use after a certain time, even if the patient is over 40 years old. However, late reproductive age is not a reason to believe that the first attempt of IVF will be ineffective, the chances of such an attempt are lower than those of young girls.
What causes infertility
There are female and male reasons. The greatest probability is in couples, where the health of the future mother is all right, but his father has little activity or a limited number of spermatozoa. In this case, doctors recommend using IVF with ICSI when the sperm is injected with a special needle into the body of the egg. It is believed that the probability of fertilization in this method is higher than all others and more often works the first time.
Women with already high chances ofchildren naturally or from previous IVF, in this case the diagnosis is "secondary infertility". Good results from the first attempt can be expected in case of obstruction of the fallopian tubes or their absence.
The most difficult cases are the presence of endometriosis,leading to thinning of the walls, loss of their qualitative characteristics, as a result of which the embryo can not attach to the uterus. Therefore, the preliminary examination and treatment of future parents is important, in order to minimize all possible causes of failure. It happens that it is impossible to get pregnant because of genetic peculiarities, in this variant it is necessary to calculate for 3-5 "replanting".
Professionalism of medical personnel
In this issue, almost 50% of success depends on the qualifications of doctors. To ensure the effectiveness of the procedure was high, they should be individually arranged with each pair:
The most important stage in the preparation isthe definition of the hormonal background, namely such indicators as AMG, FSH and LH. They not only tell the doctors the correct protocol scheme, but will also give an opportunity to assess the likelihood of pathologies in advance. For example, when diagnosing hyperprolactinaemia in patients, hypo- or hyperthyroidism, IVF can be ineffective or even not work even after several attempts.
In addition, laboratories should be equipped with the most modern equipment, where it is possible to conduct fertilization, to assess in advance the quality of embryos and their ability to develop.
In general, one must understand that every organismand how all the processes necessary for the beginning of pregnancy and the normal development of the baby will work, depends solely on himself. Often failures can cause stress, poor nutrition, poor environmental conditions, and a woman after embedding embryos may not fully comply with all recommendations, which will cause failure at the first attempt.
To increase the chances, it is necessary to respect allrecommendations of specialists, a clear understanding of each stage of in vitro fertilization and, of course, the belief that everything will necessarily happen. And if not the first time, then the second or third!
