Live birth rates
No live birth rates to show. This clinic is listed from Spain's register of licensed assisted reproduction centres (CNRHA), which publishes no results for each clinic. We have not yet read the clinic's own website for live birth rates.
Figures can be missing for ordinary reasons: too few cycles for a regulator to publish a rate, a new licence, or a country whose regulator reports national totals only.
Before you commit to treatment, ask the clinic for live births per embryo transferred for your age group, the year the figure covers and the number of cycles behind it, and ask which body regulates the clinic.
Clinical pregnancy rates (not live births)
From Spain's official national register, which every Spanish clinic must report to. For 2023, it gives the range the chance of a clinical pregnancy (a pregnancy sac seen on ultrasound) fell in for each embryo transfer, by the woman's age. The more cycles a clinic ran, the narrower its range.
These are pregnancies, not births. Some pregnancies end in miscarriage, so these figures run higher than live birth rates and cannot be compared with HFEA or US figures. The register itself warns that comparing clinics can mislead, because each treats different patients.

Key facts
Flights and stays for one person only. Not included: a companion, local transport, UK monitoring scans, time off work, insurance, or rebooking if a cycle is cancelled.
Treatments offered
UK clinics are regulated by the HFEA (Human Fertilisation and Embryology Authority). The UK's independent regulator of fertility treatment. Every UK clinic must be licensed and inspected by the HFEA, and its public register publishes success rates, patient ratings and inspection ratings for each one. The HFEA does not endorse this site, and figures here are no substitute for the register.
