The Claim
Serum testosterone, dihydrotestosterone, and estradiol levels in men exhibit a non-uniform age-related decline, with a more rapid reduction occurring after age 80, indicating a threshold effect in late-life androgen metabolism.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In men, levels of testosterone, dihydrotestosterone, and estradiol decline with age, and the rate of decline accelerates significantly after age 80.
See the scientific wording
The age-related decline in serum testosterone, dihydrotestosterone, and estradiol in men is not uniform, with a more rapid reduction occurring after age 80, suggesting a potential threshold effect in late-life androgen metabolism.
After age 80, the testes lose their ability to produce testosterone and other sex hormones because the cells that make these hormones stop working properly, and the signals from the brain that tell them to produce hormones also weaken, causing hormone levels to drop quickly.
What the research says
1 studyStudy: Age-specific population centiles for androgen status in men.
In older men, testosterone, DHT, and estradiol levels slowly go down after age 35, but they really start dropping fast after age 80 — and this study found exactly that pattern in thousands of men.
