Does TRT cause heart problems?

Last updated: January 2026

Quick Answer

The landmark TRAVERSE trial (2023) involving 5,204 men showed TRT does not increase cardiovascular events compared to placebo. However, TRT does increase hematocrit, which raises blood viscosity. Regular blood work and hematocrit monitoring are essential. Men with existing heart conditions should discuss risks with their cardiologist.

Safety is the most important consideration when starting TRT. Testosterone has been prescribed for decades with a well-established safety profile when properly monitored. The key is working with a qualified provider who orders regular bloodwork.

Staying Safe on TRT

  • Only obtain testosterone through licensed healthcare providers and pharmacies
  • Get regular bloodwork every 3-6 months (CBC, metabolic panel, hormones)
  • Monitor hematocrit, PSA, and liver function
  • Report any cardiovascular symptoms immediately
  • Never adjust your dose without consulting your provider
