Rasha Zenasni: Shared Biological Pathways Between Male Infertility and Neurodegeneration
Rasha Zenasni, Laser Technician at Blooming Center, shared a post on LinkedIn:
“Male infertility and neurodegenerative diseases: what if it all started long before the symptoms?
Recent data from a systematic review (2026) shed particularly interesting light on a concept that is still underestimated: male infertility as an early marker of neurological vulnerability.
What the data shows:
Infertile men show a significant increase in systemic oxidative stress, with levels of sperm DNA damage of up to +20-30% compared to fertile controls.
Mitochondrial alterations are observed in up to 40% of idiopathic infertility cases, with a direct impact on sperm motility.
These same biological signatures (oxidative stress, mitochondrial dysfunction, apoptosis) are consistently found in neurodegenerative diseases.
A key point: the convergence of mechanisms
Neurons and sperm share:
- a strong mitochondrial energy dependence
- Extreme sensitivity to oxidative stress
- vulnerability to protein and DNA alterations
This parallelism suggests a common systemic vulnerability and not two independent pathologies.
Towards a paradigm shift
Traditionally thought of as a local disorder, male infertility may actually reflect: a global biological imbalance a breeding ground for neurodegeneration an early warning signal potentially detectable years before neurological clinical manifestations
Major clinical involvement This opens up new perspectives:
Integrating the assessment of male fertility into a predictive medicine approach
Exploring common brain-gonad biomarkers, rethinking infertility as a window of observation of cellular aging
Male infertility is not only a reproductive issue, but could be a mirror of overall neurological health
A transversal approach, at the interface between neurology and reproduction, is now essential.
