Effect of Androgens on Human Fascia (PMID: 40723308)
Research Question
Do androgens (male sex hormones) influence how human fascia remodels and produces collagen?
This study investigated whether human fascia contains androgen receptors (AR) and whether dihydrotestosterone (DHT) affects collagen production by fascial fibroblasts.
Methods
Researchers collected samples of fascia lata and thoracolumbar fascia from adult human donors and studied them in the laboratory.
They examined:
Whether fascial tissue expresses androgen receptors (AR)
How different concentrations of DHT affect fibroblast activity
Changes in collagen production and composition
Fibroblasts were exposed for 24 hours to DHT levels designed to reflect:
Female physiological levels
Average male physiological levels
Higher male-level exposure
Researchers then measured:
Total collagen content
Collagen type I
Collagen type III
Key Findings
The study showed that fascia responds directly to hormonal signals.
Main findings included:
Androgen receptors were present in all fascial samples, showing that fascia is hormonally responsive.
Lower-dose DHT exposure increased collagen type I production.
The same lower dose reduced collagen type III expression.
Higher DHT concentrations produced smaller or less noticeable effects on collagen changes.
The response appeared to be dose-dependent, meaning fascia reacted differently depending on hormone levels.
Overall, DHT influenced how fascial fibroblasts build and organize the extracellular matrix.
Why It Matters for Fascia
This study adds to growing evidence that fascia is not only influenced by movement and mechanical loading—but also by hormonal signaling.
Because collagen composition affects tissue behavior, hormonal changes may influence:
Fascial stiffness
Tissue adaptability
Force transmission
Recovery and remodeling
Sensitivity and pain experiences
The findings may also help researchers better understand why fascial characteristics and symptoms sometimes differ across individuals.
5 Takeaways
Human fascia contains androgen receptors and can respond directly to hormones.
DHT influences collagen production inside fascial tissue.
Lower hormone concentrations produced stronger changes in collagen subtype balance.
Fascia remodeling appears to be influenced by both biochemical and mechanical factors.
Hormonal regulation may contribute to differences in fascial properties and pain patterns.
