IVF/ICSI with own oocytes

In vitro fertilisation using the patient’s own eggs.

Pregnancy probability per transfer, by the woman’s age

Out of every 100 embryo transfers performed at this centre, how many resulted in a pregnancy, by the woman’s age.

Why is this measure important?

It is the figure closest to the question “what are my chances?”: the outcome of each transfer, in your age group. The woman’s age is the factor that weighs most on the result — which is why we never show a single overall rate.

Detailed explanation

The registry publishes every rate as an interval: the floor and the ceiling of the centre’s estimate. A wide interval usually means few cycles (more chance at play); a narrow one, more activity. Important: the Spanish registry publishes pregnancies, not live births — some pregnancies do not reach term, so this is not a birth rate. And each clinic treats different patients: comparing raw figures between centres can be misleading.

Embryo implantation rate

Out of every 100 embryos transferred at this centre, how many implanted in the uterus.

  • This clinic (published interval)
  • National average
Fresh embryos0 – 71.1%
National average29.3%
Frozen embryos11.6 – 38.4%
National average37.1%

Treatment year: 2023.

Why is this measure important?

It measures the outcome embryo by embryo — the finest denominator the registry publishes: it lets you compare centres that transfer a different number of embryos per attempt.

Detailed explanation

It is calculated per embryo transferred, not per transfer: if two embryos are transferred and one implants, the transfer counts as a pregnancy, but implantation is 50%. The registry publishes it as an interval, without an age breakdown. It measures implantation, not a full-term pregnancy or a birth.

Artificial insemination

Pregnancy probability per cycle started

Pregnancy rate per cycle in women under 40.

AID — artificial insemination (donor sperm)

Donor sperm placed in the uterus.

Under 35Not applicable
National average22.1%
Between 35 and 39100 – 100%
National average16.4%

Treatment year: 2023.

Why is this measure important?

Insemination is the least complex technique and also the one with the lowest probability per attempt: the measure is pregnancy per cycle started, not per transfer, because insemination involves no embryo transfer.

Detailed explanation

AIH means insemination with the partner’s sperm; AID, with donor sperm. The registry publishes the pregnancy percentage per cycle as an interval, stratified by the woman’s age (up to 2014, a single “under 40” band). These are recorded pregnancies, not births.

Other techniques

Pregnancy probability per transfer (intervals as published by the registry).

Sperm donation1 – 99%0 – 86.7%
Embryo donationNot applicable

Treatment year: 2023.

Why is this measure important?

These techniques do not fit the sections above, but the registry publishes their results too: they matter if your treatment involves PGT, vitrified eggs, or embryo or sperm donation.

Detailed explanation

Each row is the pregnancy probability per transfer for that technique, as published by the registry (intervals, never reduced to a single number). PGT is published as a rate per transfer — not as the share of cycles using PGT.

IVF/ICSI with own oocytes

Embryos per transfer

The SEF recommends transferring 1 or 2 embryos whenever possible.

Fresh

  • 1 embryo: 6
  • 2 embryos: 0
  • 3 embryos: 0

Frozen

  • 1 embryo: 30
  • 2 embryos: 5
  • 3 embryos: 0

Type of pregnancy achieved

A singleton pregnancy is the best outcome after fertility treatment. Composition of recorded pregnancies: these are pregnancies, not deliveries.

Fresh transfers · with 1 embryo

  • Singleton: 100%
  • Twin: 0%
  • Triplet or more: 0%

Frozen embryo transfers · with 1 embryo

  • Singleton: 100%
  • Twin: 0%
  • Triplet or more: 0%

Frozen embryo transfers · with 2 embryos

  • Singleton: 100%
  • Twin: 0%
  • Triplet or more: 0%

Artificial insemination

The registry census lists the services each centre declares; it does not publish the ones it does not offer, so nothing here is marked as “not available”.
