TLDR Testosterone and finasteride improve muscle strength and size after spinal cord injury.
This randomized, double-blind, placebo-controlled pilot study evaluated the effects of high-dose testosterone plus finasteride (T+F) on knee extensor (KE) strength and cross-sectional area (CSA) in 10 men with impaired gait and low to low-normal testosterone following chronic incomplete spinal cord injury (SCI). Participants received T+F or a placebo for 6-12 months. Results showed significant improvements in KE strength and CSA in the T+F group compared to the placebo group, with notable increases in isometric and isokinetic torque and CSA at both 6 and 12 months. The study suggests that T+F can enhance muscle strength and size in this population, warranting further investigation through larger clinical trials.
