Objectives:
This study evaluated the effects of exogenous testosterone molecule-1 (CADM1) pathological defect during early and chronic periods of spinal cord injury (SCI).
Materials And Methods:
In this experimental study, Testosterone was administered immediately or after one week of SCI induction. Along with quantification of CADM1 gene expression and its immunoreactivity, we evaluated sperm parameters and serum testosterone level post-SCI.
Results:
Different grades of abnormalities in sperm parameters and testis architecture were observed along with significant reductions in the level of CADM1 expression and its immunoreactivity in the seminiferous tubules of both acute and chronic SCI groups. Exogenous testosterone, by compensating the serum testosterone level. reduced the percentage of apoptotic and both short head and abnormal sperm froms in the caudal epididymis. Importantly, the beneficial effects of immediate administration of testosterone were prominent. Increases in the level of CADM1 transcription and its immunoreactivity in the testis of SCI mice treated with testosterone were accompanied by improvement of sperm motility as well as testicular Johnsen's and Miller's criteria.
Conclusions:
Since immediate testosterone treatment improved the immunoreactivity and transcription level of CADM1, the observed beneficial effect of exogenouse testosterone can be attributed to its effect on CADM1 dynamics.
Insights
Testosterone treatment improved sperm parameters and testis function after spinal cord injury (SCI). Immediate testosterone administration was most effective, enhancing CADM1 expression and sperm quality in SCI mice.
Area of Science:
- Reproductive biology
- Neuroscience
- Endocrinology
Background:
- Spinal cord injury (SCI) can lead to significant reproductive dysfunction.
- Testosterone plays a crucial role in male reproductive health.
- CADM1 (cell adhesion molecule 1) is implicated in testicular function.
Purpose of the Study:
- To investigate the impact of SCI on CADM1 expression and sperm parameters.
- To evaluate the therapeutic effects of exogenous testosterone on SCI-induced reproductive deficits.
- To determine the optimal timing for testosterone administration post-SCI.
Main Methods:
- Experimental induction of SCI in mice.
- Administration of exogenous testosterone at different time points post-SCI.
- Quantification of CADM1 gene expression and protein immunoreactivity.
- Assessment of sperm parameters and serum testosterone levels.
Main Results:
- SCI caused abnormalities in sperm parameters and testicular architecture, with reduced CADM1 expression.
- Testosterone treatment improved sperm parameters and compensated for reduced serum testosterone levels.
- Immediate testosterone administration showed the most significant benefits, increasing CADM1 levels and improving sperm motility and testicular criteria.
Conclusions:
- Exogenous testosterone can ameliorate reproductive dysfunction following SCI.
- The beneficial effects of testosterone are linked to its influence on CADM1 expression and dynamics.
- Prompt intervention with testosterone post-SCI is recommended for optimal recovery of reproductive function.
