How many couples make use of insemination? At what age do women decide to pursue in vitro fertilisation (IVF)? What types of genetic tests are conducted on embryos? The following charts provide answers to these questions.
The table shows how many couples have had a PGD and on what grounds. In 2017, for example, one couple had its embryos tested for cystic fibrosis. The reason was that both parents were shown to have a mutation of a specific gene that can cause cystic fibrosis if the mutation is present in the embryo in two forms. It should be noted that more than 2,000 different mutations of this gene are known, and that not every mutation causes cystic fibrosis to the same extent. Mutations are also known, for example, that do not trigger cystic fibrosis or that trigger only a mild form. The evaluation of the potential effects of a mutation often also includes additional parameters such as the family history.
