Preimplantation genetic screening (PGS)

Preimplantation genetic screening (PGS)

PGS, Preimplantation genetic screening: this technique is used to identify genetic characteristics of the embryos, enabling us to select the most suitable ones for transfer and thus enhancing the chance of success.

PGD, Preimplantation genetic diagnosis: we use this technique in cases where we need to discard embryos affected by a specific inherited disease.

When is PGD necessary?

  • Recommended in the following cases:
  • Patients affected or being carries of an inherited gene mutation (monogenic disorder) who are at risk of passing it on to their offspring.
  • Patients being carriers of chromosomal abnormalities that can be passed on to their offspring.
  • Patients at a higher risk of having genetic alterations in their egg or sperm cells that could create genetically abnormal embryos.



We inform our patients that our facilities scrupulously follow the Safety measures established by the directive of the Ministry of Health to prevent the spread of COVID-19.

Each patient undergoes a medical history, temperature control and a safety questionnaire.

We have additional safety mechanisms for hand disinfection and to maintain controlled access of people to our facilities and respect the safety distance among persons

The unique health situation we are experiencing these days leads us to advocate for prudence and social responsibility. IMER and the NEXTCLINICS group are taking all necessary measures to ensure the health of our patients and employees.
