Alireza Mansouri, Associate Professor at Penn State Health, shared a post on X:
“We are seeing a major breakthrough in how we understand the male-bias in glioblastoma. For decades, the thought was that testosterone might fuel these aggressive brain tumors, but this NIH-funded study suggests the exact opposite. By regulating the stress response in the brain, testosterone may actually prevent immune exhaustion, allowing the body to fight the tumor more effectively.
The data showed a 38% reduction in mortality among men on testosterone supplements, which is a staggering figure for this disease.
However, I must highlight that we are currently looking at a retrospective association from public databases. We cannot yet say that testosterone causes better survival, as the healthy-user effect is a major confounding factor in registry data. The excitement here lies in the biological mechanism, which opens a new door for immunotherapy.
The next steps are clear: we need prospective, controlled clinical trials to validate these findings and see if we can safely translate this hormonal protection into a standard treatment for our patients.”
