Summary
This study reveals the detailed cellular structures of the human corpus cavernosum in transgender men. It identifies key components like collagen, smooth muscle, and various nerve endings.
Area of Science:
- Urology
- Histology
- Cell Biology
Background:
- The corpus cavernosum's structure is crucial for erectile function.
- Understanding its cellular composition aids in addressing related physiological conditions.
Purpose of the Study:
- To illustrate the ultrastructure of the human corpus cavernosum.
- To identify cellular components and nerve terminal types in transgender men.
Main Methods:
- Ultrastructural analysis using electron microscopy.
- Examination of penile tissue samples from eight transgender men (aged 20-30) undergoing penectomy.
Main Results:
- Demonstrated the presence of collagen and smooth muscle.
- Identified endothelial cells lining cavernous spaces.
- Illustrated various nerve terminals, including nonadrenergic and noncholinergic types, and mast cells.
Conclusions:
- Provides detailed ultrastructural insights into the human corpus cavernosum.
- Highlights the presence of diverse cellular components and nerve types, relevant for urological and physiological studies.
