Did you know that Lipoprotein(a) is largely genetic and notoriously hard to lower with diet and exercise? In fact, it's speculated that upwards of about 90% of LPA presence is genetically-mediated.
While statins are the gold standard for LDL, they often have little to no effect on Lp(a). However, research shows that Testosterone Replacement Therapy (TRT) might be a powerful tool in your cardiovascular toolkit (if clinically-warranted).
The Science Breakdown 🔍
Significant Reductions: Studies have shown that testosterone administration can decrease Lp(a) levels by an average of 28% to 37% (Zmuda et al., 1996).
The Baseline Factor: The higher your Lp(a) starts, the more significant the reduction tends to be when testosterone is optimized (Kaplan et al., 2010).
Direct Action: Unlike some hormones that work via conversion, testosterone appears to reduce Lp(a) through its direct androgenic effects as well as modulating the LPA gene's activity.
Why This Matters 🫀:
High Lp(a) is a known independent risk factor for atherosclerosis and heart disease as well as residual risk. For men with low testosterone, the risk can be even higher, as low T levels are often associated with marked elevations in Lp(a).
The Bottom Line: Optimizing your hormones isn’t just about energy and muscle—it’s about protecting your heart.
