This is a great example of why nutrition research requires a careful distinction between biological plausibility and clinical significance. The possibility that olive oil may influence testosterone is certainly interesting, especially given the broader literature on dietary fat, endocrine function, and metabolic health.

At the same time, I think the key question is how much of an effect we are talking about, in whom, and compared with what dietary pattern. Hormone levels are influenced by energy balance, body composition, sleep, exercise, metabolic health, and many other factors, so isolating the effect of a single food can be challenging.

As a physician-scientist, I find the bigger picture more compelling: dietary patterns that support cardiometabolic health may also influence endocrine physiology through multiple interconnected pathways. Rather than viewing olive oil as a “testosterone booster,” it may be more useful to understand how its role within an overall healthy dietary pattern contributes to metabolic and hormonal health. The nuance matters, but so does the potential for small, sustainable lifestyle choices to have meaningful effects over time.

Thank you!
