What is a preimplantation genetic diagnosis?

Major advances in medical research help us to improve our health and well-being in our daily lives.

This is also the case with PGD - Preimplantation Genetic Diagnosis.

In this molecular genetic diagnosis, embryos created by in vitro fertilisation are genetically examined to determine whether hereditary diseases or chromosomal abnormalities are present.

With this study of the emryo, the transmission of numerous genetic diseases from parents to children can be avoided in advance.

The process of preimplantation genetic diagnosis requires artificial insemination (in vitro fertilization). After fertilisation, one or more cells are taken from the embryos and subjected to molecular genetic testing to examine the genetic make-up.

After this genetic examination, the embryos are examined to determine which ones are suitable for transfer.

PGD has precise indications for certain types of patients. For example, for women with multiple miscarriages or multiple unsuccessful attempts at artificial insemination. This procedure is also suitable for women of increasing age who cannot become pregnant naturally.

In addition, the transmission of diseases such as cystic fibrosis, thalassaemia or muscular dystrophy and many other diseases can be prevented.

The following steps must be observed in the PGD procedure:

Step 1→ A genetic study of the embryo is performed to detect genetic changes.

Step 2→ A biopsy is performed on each of the embryos and those with a specific congenital disease are removed from the embryo culture.

Step 3→ One or two healthy embryos are transferred to the uterus. We also have the option of freezing more healthy embryos.
