Every married couple who has high hopes for IVF wants to get the result on the first try. Such a probability does exist. On average, according to statistics, 50% of in vitro fertilization procedures end successfully. However, the figure depends on many factors, including both the state of health of men and women, the competent approach to training and the professionalism of doctors. It is worth considering the natural component: even with natural fertilization, the probability of pregnancy is not equal to 100%. Normally, an absolutely healthy woman can have menstrual cycles, when immature follicles appear, which cannot function fully and form high-quality eggs that are capable of fertilization.
Let us consider in more detail what factors determine a positive IVF result the first time.
Age of the future mother
Physiologically, the female body is structured in such a way that, after the milestone of 35 years, the number and quality of germ cells begins to decline. According to official data, natural pregnancy occurs depending on age in the following cases:
- From 35 to 37 years old - in 30%;
- 38 - 41 years old - in 20%;
- 42-45 years old - at 5%.
Thus, it is better not to postpone the IVF procedure, especially since modern technologies allow you to freeze the obtained eggs to use after a certain time, even if the patient is older than 40 years. However, the late reproductive age is no reason to believe that the first attempt at IVF will be ineffective, just the chances of such a lower than that of young girls.
What is the cause of infertility?
There are female and male causes. Most likely there are couples where the health of the future mother is all right, but the father has low activity or a limited number of sperm. In this case, doctors recommend using IVF with ICSI when the sperm is inserted 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 often works the first time.
Also, women who already have children in a natural way or from previous IVF have a great chance, in this case they are diagnosed with secondary infertility. Good results on the first try can be expected even with obstruction of the fallopian tubes or their absence.
The most difficult cases are the presence of endometriosis, which leads to thinning of the walls, loss of their qualitative characteristics, as a result of which the embryo cannot attach to the uterus. Therefore, a preliminary examination and treatment of future parents are important in order to minimize all possible causes of failure. It happens that it is not possible to get pregnant because of genetic features, in this option it is worth counting on 3-5 “replants”.
Professionalism of medical staff
In this matter, almost 50% of success depends on the qualifications of doctors. In order for the procedure to be effective, they must individually with each pair:
- Conduct a comprehensive examination, identify problems not only with the sexual sphere, but also concomitant diseases;
- To carry out high-quality treatment of existing diseases;
- Suggest the most optimal in vitro fertilization protocol;
- It is good to carry out the procedure for extracting an egg from a mature follicle, and after a few days - transfer it to the uterus.
The most important stage in the preparation is the determination of the hormonal background, namely such indicators as AMH, FSH and LH. They will not only tell doctors the correct protocol scheme, but also provide an opportunity to assess in advance the likelihood of pathologies. For example, when diagnosing hyperprolactinemia in patients, hypo- or hyperthyroidism, IVF may be ineffective or not work at all even after several attempts.
In addition, laboratories should be equipped with the most modern equipment, where it is possible to carry out fertilization, to evaluate in advance the quality of embryos and their ability to develop.
In general, you need to understand that each organism is individual, and how all the processes necessary for the onset of pregnancy and the normal development of the baby will work out depends solely on himself. Often failures can be caused by stress, poor nutrition, poor environmental conditions, and a woman after embryo “sitting down” may not fully comply with all the recommendations, which will cause failure at the first attempt.
To increase the chances, it is necessary to comply with all the recommendations of specialists, a clear understanding of each stage of in vitro fertilization and, of course, the belief that everything will work out. And if not the first time, then the second or third!
