Abstract:
Stainless steel type AISI 316L is widely used in orthopaedic surgery. The toxic effects of its corrosion products on the morphology of mouse seminiferous cells were investigated. Chemical elements from stainless steel were released into a physiological medium using an electrochemical method. This metallic solution was injected subcutaneously into male Charles River mice at 72 h intervals for 10 days. Electron microscopic observations of seminiferous tubule thin sections showed that the metallic suspension caused tissue vacuolation, cell degeneration, and multinucleated cell formation. This apparent tissue toxicity induced by stainless steel corrosion products suggests that long term implantation of such biomaterials may impair spermatogenesis.
Insights
Corrosion from 316L stainless steel implants releases toxic elements. These elements negatively affect mouse testicular cells, potentially impairing sperm production with long-term use.
Area of Science:
- Biomaterials Science
- Toxicology
- Reproductive Biology
Background:
- 316L stainless steel is a common biomaterial in orthopaedic surgery.
- Concerns exist regarding the potential toxicity of metallic corrosion products from implants.
Purpose of the Study:
- To investigate the toxic effects of 316L stainless steel corrosion products on mouse seminiferous cell morphology.
Main Methods:
- Stainless steel elements were released electrochemically into a physiological medium.
- The resulting metallic solution was injected into male mice over 10 days.
- Seminiferous tubules were examined using electron microscopy.
Main Results:
- Exposure to stainless steel corrosion products induced tissue vacuolation.
- Observed cell degeneration and multinucleated cell formation in seminiferous tubules.
- Evidence of significant testicular tissue toxicity.
Conclusions:
- Corrosion products from 316L stainless steel exhibit toxicity to testicular cells.
- Long-term implantation of this biomaterial may negatively impact spermatogenesis.
- Further research is needed to assess the reproductive risks associated with stainless steel implants.
