Introduction
My specific area of interest and expertise focuses on the impact of cancer treatment on fertility potential and the prevention of infertility through fertility preservation strategies. My projects investigate the safety and efficacy of these strategies in oncologic patients in prospective cohorts, as well as in other patient groups. Assisted reproductive technologies are also in the focus of my research. For more information: https://ki.se/en/onkpat/research-team-kenny-rodriguez-wallberg
