How to Optimize Testosterone & Estrogen | Huberman Lab Essentials
Andrew Huberman
Feb 20, 2025
Episode description
In this Huberman Lab Essentials episode, I explain how to optimize hormones—particularly testosterone, estrogen, and related sex steroids—to enhance fertility and overall well-being.
I discuss the sources of testosterone and estrogen and how their levels fluctuate with age in both males and females. I also cover how behaviors such as exercise, cold and heat exposure, light exposure, illness, and breathing patterns affect hormones. Additionally, I examine specific supplements and replacement therapies, highlighting important precautions to consider when adjusting hormone levels.

Mindsip insights from this episode:
Liberate bound testosterone with Tongkat Ali supplementation
The supplement Tongkat Ali, taken at 400-800 milligrams per day, can help liberate bound testosterone, making more free testosterone available.
Exercise caution in hormone modulation to reduce cancer risk
Be cautious when modulating hormones, as tissues with rapid cell reproduction like the testes and ovaries are vulnerable to androgen-sensitive or estrogen-sensitive cancers.
Lift weights before cardio to optimize testosterone levels
To optimize testosterone levels when training in the same session, it is best to perform heavy weight training first, followed by endurance activity.
Boost testosterone through competition
In the short term, the act of competing itself increases testosterone, independent of whether you win or lose.
Maintain estrogen levels to support male libido
Men will completely lose their libido if estrogen levels are brought too low, as both testosterone and estrogen are needed for a healthy sex drive.
Recognize testosterone drop in expecting fathers
Expecting fathers experience an almost 50% decrease in both free and bound testosterone levels.
Reduce inflammation to protect sex hormone levels
Inflammatory cytokines like IL-6, released during illness, are bad for sex steroid hormones and can decrease the desire for sex independent of feeling sick.
Utilize Fadogia Agrestis to boost hormone production
The supplement Fadogia Agrestis may increase luteinizing hormone, which in turn can increase the body's own production of testosterone or estrogen.
Practice nasal breathing to optimize hormone levels
Becoming a nasal breather, especially during exercise, can indirectly raise testosterone and estrogen by reducing sleep apnea and lowering cortisol.
