To each type of Assisted Reproduction procedure – programmed intercourse, intrauterine insemination, in vitro(FIV/ICSI) fertilization, recurrent miscarriage control, embryo freezing, eggs freezing, semen freezing, FIV/ICSI with preimplantational genetic diagnosis (PGD), etc – there are indicators showing if the work has been conducted in the appropriate way and following the demands of international patterns. The year comparison of these indicators serves as a parameter to each new technology, or newly introduced protocol, aiming at reaching the maximum efficiency. The pregnancy rates in FIV are the main indicators for the service as a whole. At the Fertility Center from Rede D’Or these are the following rates:
In general, the pregnancy rates for FIV/ICSI are the ones that reflect the success or the failure on the work of assisted reproduction clinics. The pregnancy rate offers to the patient a perspective on the treatment success. In other words, when the clinic has a 40% rate, four out of ten couples must get pregnant with the treatment at that moment, while other six couples will have to try it again.
The truth is that, much more important than the rate informed by the clinic, it is important to know if that institution has its data reported to the organs responsible for inspection. In Brazil, Anvisa and Rede Latino-americana de Reprodução Asistida (REDE) visit from time to time the institutions that are registered to verify if the data reported in each period is correct. REDE association works as an auditory paid by the clinic itself in order to validate its procedures. This evaluation has been more and more rigorous and carefully made by the inspecting agencies. Another institution that also collects data from the Assisted Reproduction services is SBRA (Sociedade Brasileira de Reprodução Assistida-Brazilian Society of Assisted Reproduction), however, it has not made inspections yet.
There are three big world institutions that compile and compare the results of clinics from all the continents. According to the European Society of Human Reproduction and Embryology (ESHRE, 2010), the average pregnancy rate per embryo transfer was 32,6% to ICSI (Human Reproduction Vol.29, No. 10 pp. 2.099–2.113, 2014). On the other hand, the American Society of Reproductive Medicine reports rates of 33,6% to FIV/ICSI (Fertility and Sterility, Vol. 87, No. 6, Junho 2007). But According to Rede Latino-americana de Reprodução Assistida (Latin American Assisted Reproduction Network) the average pregnancy rate per embryo transfer was 34,2% to ICSI. (Registro Latinoamericano de Reproducción Assistida, published in 2014).
Results at Vida – Centro de Fertilidade
In 2014, Centro de Fertilidade reached the pregnancy rate of 48,23% to in vitro fertilization (FIV/ICSI).
Since its creation, Vida – Centro de Fertilidade has presented the following pregnancy rates:
Percentage (%) of pregnancy per embryo transfer made:
The graphic shows that the record of the service had a mo/dest start, with rates even a little below what is published worldwide, but suitable to the apprenticeship curve and adapted to the public who searches for it, and later it got established with highly satisfactory results.
History of cases performed by Clinic Vida
Since 2005, Vida – Centro de Fertilidade has performed 6.164 treatments for infertile couples, having had an average raise of 40% per year.
Pregnancy rate(%) by age
In the following graphic we can see the influency of the woman age at the success of assisted reproduction treatments. As we can observe, from the age of 35 years, the pregnancy chances start to drop considerably.
