    Covid-19 and the Testes

    This preprint explores the effects of Covid-19 on sexual hormone levels in men. The study finds that LH levels are elevated, FSH and testosterone levels are the same. And they hypothesize that Covid-19 impairs testosterone production, so the body boosts LH levels to compensate, bringing...

    COVID-19, Pneumonia & Inflammasomes – The Melatonin Connection

    Melatonin Inhibits NLRP3 Inflammasomes Melatonin is well known for its chronobiotic effects, regulating biological functions tied to circadian rhythms. Numerous studies have revealed that melatonin exerts effects beyond the control of circadian oscillators. The NLRP3 inflammasome is now...

    Why the Coronavirus Seems to Hit Men Harder Than Women...Estrogen Levels?

    Maybe one more reason to let your Estrogen levels rise when doing TRT. Although men and women have been infected in roughly equal numbers, researchers found, the death rate among men was 2.8 %, compared with 1.7% among women.... could Estrogen levels be the key to the difference? Link To...

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
