Exploring infertility in Klinefelter Syndrome using organoid models

Unraveling the Klinefelter's Disease Physiopathology by Organoid Model

Not applicable Interventional Cliniques universitaires Saint-Luc- Université Catholique de Louvain · NCT05997706

This study is trying to understand why men with Klinefelter Syndrome have trouble with infertility by looking at their sperm cells in a lab setting.

What this trial studies

This study aims to investigate the infertility associated with Klinefelter Syndrome by isolating and expanding spermatogonial cells from affected patients. Using an organoid model, researchers will analyze how these cells interact with various combinations of somatic cell types within an extracellular matrix hydrogel. The goal is to better understand the physiological mechanisms underlying infertility in men with this genetic condition. Participants will undergo a testicular biopsy to obtain the necessary cells for this research.

Who should consider this trial

Good fit: Ideal candidates for this study are men diagnosed with Klinefelter Syndrome who are experiencing azoospermia and are candidates for testicular sperm extraction.

Not a fit: Patients with Klinefelter Syndrome who also have mosaicism may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved fertility preservation strategies for men with Klinefelter Syndrome.

How similar studies have performed: While there have been studies on Klinefelter Syndrome, this specific approach using organoid models is relatively novel and has not been extensively tested.
