Niels Jørgensen has served as the principal investigator for numerous Danish and international scientific projects examining testicular function in over 12,000 men from general, fertile, and infertile populations. His studies have detailed testicular function, including semen quality and endocrine function, and investigated the effects of external factors such as endocrine-disrupting chemicals, lifestyle, and genetics on testicular function. Beyond this, Niels Jørgensen coordinates the world’s largest cohort study on young men’s testicular function, known as The Danish Young Men Study, and chairs the Steering Committee of the Repro Union Biobank and Infertility Cohort (RUBIC). His work has significantly influenced the field of male infertility both locally and globally, leading to advancements in diagnosis and treatment, and ultimately improving patient outcomes.
