Moderne verfahren der assistierten reproduktion. Genetische aspekte

Genetic aspects are becoming more and more important in the diagnostics, patient counselling and therapy of assisted reproduction. Compared to spontaneously conceiving patients, genetic disturbances can be found with a higher incidence in patients requiring these techniques, a fact which is not only due to the greater age of such patients. In several cases, genetic disturbances contribute to or even explain infertility. New insights in the field of pharmacogenetics demonstrate that genetic dispositions influence the success of hormonal stimulation. Furthermore, growing knowledge of potential associations between genomic imprinting and assisted reproduction (ART) demands further attention, especially due to the uncovering of new potential risks of ART itself. Performing genetic diagnosis in oocytes or embryos (preimplantation genetic diagnosis, PGD) warrants further evaluation before it becomes a routine technique.
