Higher Success Rates with PGT

Preimplantation genetic testing (PGT) is permitted in Switzerland if there is a high risk of a serious hereditary disease or chromosomal disorder that cannot be prevented in any other way. It is also permitted for couples who cannot conceive naturally or who have already experienced several miscarriages.

Couples must undergo genetic counselling and the procedure must be approved by an ethics committee.

PGT may only be carried out in specialised centres, whereby the number of fertilised eggs is limited and only embryos up to a certain stage of development may be examined.

The cost of PGT depends on the type of genetic test and the number of embryos that are analysed. At Cada, the fees consist of a basic fee per cycle plus a fee per embryo.

• PGT-A and PGT-SR: CHF 950 basic fee plus CHF 600 per tested embryo
• PGT-M: Price on request, depending on the genetic question and the complexity of the test development

PGT costs are in addition to the expenses for IVF or ICSI and medication. During your consultation, we are happy to provide a clear, personalised cost estimate for your situation.

PGD can be useful if there is an increased risk of genetic diseases or chromosomal disorders in the child. This is the case, for example, if

• one or both parents are carriers of a genetic disease.
• a child has already been born with a genetic disorder.
• the woman is over 35 years old, as the risk of chromosomal disorders increases as the mother gets older.
• there is a history of several miscarriages.
• several unsuccessful IVF attempts have been undertaken.

PGD is a very safe method, but not a 100% guarantee. The accuracy of the diagnosis is over 99%. In rare cases, it can happen that a genetic change is overlooked or that an embryo is wrongly categorised as diseased.

Genetic testing of the embryo can be worthwhile for couples who have an increased risk of genetic diseases or chromosomal disorders in the child. It can help to increase the probability of a pregnancy with a healthy child and reduce the risk of miscarriage.

PGD comprises various procedures:

• PGT-A (pre-implantation genetic testing for aneuploidy): This involves analysing the number and structure of the embryo's chromosomes. Aneuploidies are numerical chromosomal abnormalities that can lead to miscarriages or genetic diseases such as trisomy 21 (Down's syndrome).
• PGT-M (pre-implantation genetic testing for monogenetic diseases): This involves a targeted search for a specific genetic change that causes a monogenetic disease, e.g. cystic fibrosis or Huntington's disease.
• PGT-SR (pre-implantation genetic testing for structural chromosomal abnormalities): This examines structural changes in the chromosomes, e.g. translocations or inversions.

The costs of PGD are not covered by compulsory health insurance (OKP) in Switzerland. Any assumption of costs by the health insurance fund must be checked on a case-by-case basis.

No. PGT can lower the risk of certain genetic conditions and miscarriages, but it does not replace prenatal diagnostics during pregnancy. We still recommend the usual pregnancy check ups after PGT. This includes ultrasound scans, the first trimester test and, if needed, NIPT or further tests to monitor your baby’s development.

No. In Switzerland it is legally forbidden to choose the sex of a child for non medical reasons.
