Even as our understanding regarding the various diagnostic and clinical aspects of reproductive failures rapidly expand in recent years, many issues remain unresolved, some of them concerning the success of assisted reproductive technologies (ART) and management of risk pregnancies.

“2020: Successes and Failures in Reproduction” will aim to point out, discuss and hopefully enlighten the hot topics in Reproductive failures research, opening a road to new ideas and collaborations in the field of clinical practice.

The Workshop will focus on the following key topics:

  • Hereditary and acquired thrombophilia in pregnancy
  • Peripheral and uterine NK cells
  • Tregs
  • Endometrial microbiome and chronic endometritis
  • Stem cells and reproduction
  • Immune modulating therapies in reproductive failures
