Testosterone and Neural Function

Spinal cord injury (SCI) disrupts the nerves controlling movement, along with those that regulate functions like heart rate and blood pressure (known as the autonomic nervous system, or ANS). Testosterone (T) plays a significant role in brain health and ANS reflex function in non-neurologically impaired men. However, little is known about the relationships between T, nerve function, and ANS dysfunction after SCI. Interestingly, up to 60% of men with SCI exhibit persistently low T concentrations, which may worsen nerve and ANS dysfunction. In uninjured eugonadal people (normal physiologic range of serum T concentrations), a single pharmacologic dose of intranasal T has been shown to quickly improve nerve function, but no study has evaluated if T administration alters nerve and ANS function in men with SCI. Herein, the investigators will conduct the first study to test how a single dose of intranasal T impacts motor and ANS function in this population.

How this works

  1. Answer a few questions

    About 5 to 10 minutes. Skip-friendly where possible.

  2. We forward your profile to the study team

    They see only the answers needed to decide if you can be screened.

  3. The team reaches out to schedule screening

    Usually within a few business days, via the contact you give.

We save your progress under this email so you can come back later, and the study team uses it to reach you.
