Hormones insights
Peer-reviewed hormones research, translated into plain English.
Does testosterone therapy help erectile dysfunction?
Testosterone therapy helps erectile dysfunction in a minority of men, those with low testosterone confirmed by blood tests, and the trials disagree.
Does HRT help with hot flushes? About 75% fewer, reviews agree
HRT cuts hot flushes by roughly three-quarters, and the added risk of stroke, clots or breast cancer runs near one extra case per 1,000 women a year.
Do growth hormone peptides work? The trials stop before ageing
Sermorelin, ipamorelin and CJC-1295 do raise growth hormone. Reviews of the ageing growth hormone axis stop short of recommending growth hormone peptides.
Is testosterone therapy safe long term? The evidence runs about three years
The largest heart-safety trial treated men for roughly two years. Whether testosterone therapy is safe long term rests on one study that disagrees.
Is TRT a lifelong treatment? It depends on why testosterone is low
Whether TRT is a lifelong treatment depends on the cause of the low testosterone - permanent damage to the glands, or obesity, which can be reversible.
