Published: Friday 24.7.2026
Researchers from the Institute of Biotechnology of the Czech Academy of Sciences at the BIOCEV Centre, the Faculty of Science, Charles University, and the Czech University of Life Sciences Prague have, for the first time, comprehensively described tiny membrane vesicles that transfer essential molecules from epididymal cells to sperm during their maturation. The discovery could contribute to improving assisted reproduction techniques and the diagnosis of male infertility in the future.
