Effectiveness of treatment
Nothing demonstrates the effectiveness of treatment better than the sight of the developing foetus on ultrasound or the birth of the child. We regularly and very carefully monitor the effectiveness of the treatment we offer. We are also very keen to listen to the voice of our patients. We want to respond to the feedback we receive immediately so we can constantly improve.

IVF efficacy per treatment cycle
We have calculated and presented the treatment success rates at TFP Fertility Macierzyństwo, as shown below, in a clear and reliable manner, illustrating the effectiveness of each stage of treatment as clearly as possible.
To determine treatment success as accurately as possible, it is worth considering one full cycle of in vitro fertilisation – that is: one hormonal stimulation cycle culminating in egg retrieval, fertilisation and embryo culture, with the embryos subsequently transferred via embryo transfer (fresh and thawed embryos) until clinical pregnancy is achieved (visible gestational sac on ultrasound).
In the analysis below, we considered all patients up to the age of 38 who commenced IVF treatment (defining the start of treatment as the date of egg retrieval) and checked whether they had managed to become pregnant within one year of starting treatment (clinical pregnancy, confirmed by ultrasound, not biochemical!). Most patients had only one embryo transfer, whilst the rest had two or three.
We therefore calculated the chances of achieving pregnancy for a patient starting treatment at our clinic who undergoes a single cycle of in vitro fertilisation.

The effectiveness of in vitro treatment
We know just how stressful it is to wait for the results of a pregnancy test following embryo transfer. We are therefore all the more delighted that our clinic has achieved success rates well above the Polish average. Below, we present the success rates of our transfers, calculated as the incidence of clinical pregnancy.
Success rates for embryo transfer – clinical pregnancies | A- fresh transfer | B- thawed embryo transfer without PGT | C- thawed embryo transfer with PGT | D- transfers in oocyte donation cycles (fresh and frozen) |

Transfer efficiency with and without PGT
Preimplantation genetic testing (PGT) enables the transfer of genetically normal embryos, thereby increasing the chances of pregnancy and the birth of a healthy child. This increase in effectiveness is particularly evident in the oldest group of patients (advanced age is associated with a higher risk of genetic abnormalities, which PGT effectively eliminates).

Childbirth
We consider treatment to be successful when a baby is born. That is why we closely monitor the progress of pregnancies following embryo transfers and collect information on births.

IVF is not the only treatment for infertility – in many cases, less advanced forms of treatment, selected on an individual basis following diagnosis, can also be effective.
