Course type
Basic

Course description
This precongress course will cover the factors leading to reproductive failure and their consequences on individual’s health. Starting from the genetics of male and female infertility where monogenic aetiology will be examined, we will then discuss chromosomal, genetic and epigenetic causes of embryo arrest and miscarriages. Finally, we will elaborate on the new approach for the diagnosis of reproductive failure through the detection of lethal variants.

Target audience
Reproductive geneticists, gynaecologists, andrologists, embryologists

Educational needs and expected outcomes
As 1/6 couples in developed countries worldwide are facing infertility issues, reproductive (epi)genetics have now developed various tools and diagnostic tests for the diagnosis of infertility in couples, and more specifically for those with “unexplained” infertility. Research findings suggest that the genetic causes of reproductive failure are extremely variable; thus, new diagnostic approaches covering all potentially deleterious factors leading to reproductive failure are of outmost importance.

Participants will be able to foster a deeper understanding on the current advancements in reproductive genetics for the diagnosis of reproductive failure and critically assess their utility, validity and possible limitations.

Innovative aspects of the course
Innovative genetic testing options will be presented in this course for the assessment of embryo developmental arrest and reproductive failure.
