Results of Fertility and AHR treatments
The following results show us something very important.
At Fertilab Barcelona, we achieve these IVF results by carrying out transfers of a single embryo (blastocyst).
- Always blastocyst (Day+5, Day+6). High-quality and viable embryos.
- At Fertilab Barcelona, we achieve the following results in IVF treatments by transferring a single embryo (blastocyst), prioritizing our patients’ health (we avoid risks and twin pregnancies).
- All cases with Embryoscope+. The best embryo culture and development technology is available at Fertilab Barcelona.
- We lead the application of reproductive genetic techniques and studies with the aim of increasing treatment success rates from the very first attempt.
