A healthy cell has 46 chromosomes which hold within them the complete genetic information. In rare cases a defect in this information exists. This can be a part of one chromosome relocating to another chromosome (translocation) or one chromosome missing completely.


Such defects can be diagnosed by taking a blood sample (karyogram). However, the changes in individual genes which transmit certain hereditary diseases to the child cannot be determined with this method. Dependant on the reason for infertility a higher risk of chrosomal anomaly (changes in the genetic information) can be detected in certain couples.

In the case of restricted sperm quality, for example, the risk for microdeletions of the Y-chromosome (a missing piece of the Y-chromosome) is higher. In the case of an occlusion of the seminal duct a mutation in the CFTR gene (gene for the existence of cystic fibrosis or mucoviscidosis) can be present. These changes in genetic material can be passed on. If the other partner is also a carrier of genetic changes the child might suffer from certain diseases. The most common genetic changes (even with “healthy” carriers) are mucoviscidosis (cystic fibrosis) and thalassaemia.

Genetic consultation

Our partner for genetic consultations is Ass.Prof.Priv.Doz.Dr. Franco Laccone who is working at the institute for medical genetics (Medical University Vienna). In order to conduct a consultation with Dr. Laccone you need a referral from the Kinderwunschzentrum or your attending physician – the costs will be partially covered by your health insurance.
