Many potential customers of the reproductive centers, are interested in finding out about what chance do they have of getting pregnant after applying this method of solving problems with fertility. IVF Statistics say that the figure is an average of 30-40%, depending on the clinic and the circumstances of each individual infertility case.
With every passing day ART is becoming more and more popular, and many couples have already used methods of infertility treatment like IVF. Approximately 15% of the Russian couples suffer from infertility according to the stats. This fact is explains the relatively high popularity of the reproductive centers and the increase in the number of their clients. However, people should understand that no doctor is able advise their patients on how to get pregnant a 100 percent. After all, even with the help of modern equipment the chance for a successful completion of the first IVF attempt, is at best 55-60%. Therefore, one must be prepared for the possible need of multiple IVF programs.
Although there is no way to guarantee a 100 percent result, it is well known what increases the chances of becoming pregnant using IVF.
The most important factors that influence the outcome of such a method of overcoming fertility problems are:
- A woman's age.
- The direct cause of the fertility problems.
- The duration of infertility.
- The total number and the quality of the embryos that are obtained during IVF.
- The quality of preparation and the state of the uterine lining before the embryo transfer itself.
- Previous failed attempts and the results of IVF in the past.
- Specifics of the clinic’s client’s behavior , their way of life, bad habits etc. All this affects the success of IVF. The effectiveness can be significantly reduced even because of smoking or alcohol abuse.
- Hereditary factor.
As you can see, there are plenty of little details on the side, that can directly affect the final result of IVF. The percentage of success in each case can not be calculated.The doctor can help you evaluate the probability of a successful fertilization, after reviewing all the factors that may influence the process.
According to the current results of the research in the field of assisted reproduction, it is believed that in vitro fertilization is the most effective method to overcome infertility. It ensures an effectiveness of 40% of the IVF on average, which is the highest figure, if compared with the other methods.
But also one should understand that these numbers may not be identical in different clinics. A lot depends on the staff, the quality of medical equipment or the correctness of the preparation of the couples for IVF. The chances of success in one reproductive center may be equal to 15 per cent, meanwhile at another - 60%. So do not choose a clinic only for their price.
Below is the data on ART cycles in the US in 2003 with own (not donor egg cells). Below are records of how many women of a certain age, who started an ART program reached a particular stage of the program:
It is a well-known fact that not every couple is lucky enough to have a successful IVF after the very first attempt in overcoming infertility. However, if such cycles are repeated several times, then the chance of conception increases about 2 times. On average, after the fourth attempt of in vitro fertilization the possibility of a positive completion of the therapy is not 40 but already 80 per cent.
Below is the summary of the percentages of births per ART program depending on the patient's diagnosis (non-donor eggs):
Additionally, if the pair listens to the doctor’s advice on how to increase the chances of getting pregnant (good nutrition, proper exercise, avoidance of harmful habits, etc.), it is almost always possible to achieve a positive outcome by the end of the IVF procedure. The results speak for themselves - from the twenty years of in vitro fertilization the successfulness of assisted reproduction has increased from 8 to 40 percent. All thanks to the acquired experience, improvement of the equipment and the development of new assisted reproductive technologies.

However, customers need to be mentally ready for possible unsatisfactory results. It is not always possible to ensure success with IVF. There may be plenty of reasons for such an outcome. Most doctors do not recommend attempting artificial insemination more than 4 times, since after that the chances of success reduce significantly. Although there are cases recorded in history, in which women were able to get pregnant after 10th-12th IVF attempt.
For comparison, below presented is the data on the number of births after IVF (including prolific) for patients younger than 35 years, who had their remaining embryos after the transfer cryopreserved (ie the embryos transferred were not the only ones obtained from this patient). In this group, the possibility of pregnancy when transferring only one embryo was about 40%.
Below is a table that compares the percentage of births after the transfer of fresh and thawed embryos:
One way or another, but at the moment in vitro fertilization is the most effective method to overcome infertility.
