A Comprehensive Survey and Evaluation of Preimplantation Genetic Testing Practices in Canadian Assisted Reproductive...

In Canada, access to provincial funding for fertility treatments, such as in vitro fertilization (IVF) and preimplantation genetic testing (PGT), vary significantly. Despite rising demands, the lack of data on current practices across Canadian assisted reproductive technology (ART) clinics has contributed to the absence of standardized guidelines to support clinics offering these services. This pilot study surveys fertility clinics to examine current demands and practices related to PGT, while also exploring providers' perspectives on its implementation and future applications.

A 40-question survey was distributed to Canadian ART clinics offering IVF and PGT services.

The responses confirm that there is a high demand for IVF and PGT services. Although clinical criteria for PGT for aneuploidy (PGT-A) were generally consistent across clinics, views on its effectiveness and eligibility for public funding varied. PGT for monogenic disorders (PGT-M) appears to be widely available, and respondents showed strong support for public funding in cases involving serious heritable conditions.

This study outlines current practice and highlights variations across clinics, while also presenting the perspectives of providers of ART clinics throughout Canada. It also provides a degree of foresight as to the direction the PGT practice may take in the coming years.
