    Paraplegic men show abnormal pituitary hormone levels, with exaggerated follicle-stimulating hormone (FSH) and luteinizing hormone (LH) responses to LHRH. This suggests a direct neurological effect on testicular function.

    Area of Science:

    • Neuroendocrinology
    • Reproductive Medicine
    • Urology

    Background:

    • Spinal cord injury can impact hormonal regulation.
    • Pituitary hormone function in paraplegia requires further investigation.

    Purpose of the Study:

    • To assess the pituitary response to LHRH in paraplegic men.
    • To investigate potential links between neurological damage and reproductive hormone levels.

    Main Methods:

    • Administered LHRH injections to paraplegic men and healthy controls.
    • Measured basal and stimulated levels of FSH and LH.
    • Assessed plasma testosterone levels.

    Main Results:

    • Elevated basal FSH and LH levels were observed in most paraplegic men.

  • Exaggerated FSH and LH responses to LHRH were common.
  • Three patients exhibited subnormal plasma testosterone, suggesting depressed testicular function.

    • Conclusions:

    • Paraplegia is associated with significant alterations in pituitary gonadotropin regulation.
    • The observed hormonal changes are likely due to direct neurological effects, not urinary tract infections.
    • Further research into the neuroendocrine consequences of spinal cord injury is warranted.
