We publish what the research actually shows.
Including what it does not. Women’s midlife health is the part of medicine where the evidence was thinnest for longest, and where the marketing is loudest now. So we write down what is well established, what is emerging, and what is being sold far ahead of its evidence.
How we grade evidence
Every article carries one of three labels. They are about the strength of the human evidence, not about how interesting the idea is.
Controlled human trials, replicated, with outcomes that matter.
Some human data, often small or short, and not yet settled.
Plausible biology, little or no human outcome evidence. Sold far ahead of what is known.
Explainers
Watch the explainers
Short, silent and captioned — the kind of thing that is easier to see than to read.

Perimenopause & menopause
The transition itself: what changes, when, and what is treatable.
Perimenopause: the years before the thing everyone names
It can start in your late thirties, last a decade, and be missed entirely because a single blood test came back normal.
Why a single hormone test misleads in both directions
The same woman can look post-menopausal on a Tuesday and entirely ordinary nine days later. Timing is not a detail.
Waking at three: the perimenopausal sleep pattern
Falling asleep is usually fine. Staying asleep is the problem, and it often arrives before any other symptom.

Fertility & later-life pregnancy
Ovarian reserve after 35, preconception health, and what these markers genuinely cannot tell you.
AMH tells you about quantity, not about whether you can conceive
The single most misread number in women’s health, and the one most often sold as a fertility score.
Preconception: the boring list that actually changes outcomes
Five things with real evidence behind them, none of which are sold as a protocol.
Pregnancy after 35, stated honestly
The risks are real and are usually quoted badly. Here is what changes, what does not, and what is actually modifiable.

Hormone therapy
What menopausal hormone therapy does, who it suits, and the risks stated honestly.
Menopausal hormone therapy: what the evidence actually says now
A generation of women were taken off it on the strength of a headline. Here is the more careful reading, including the risks.
Testosterone in women: one indication with evidence, and a lot of marketing
The international position statement is narrower than almost any clinic website suggests.

Weight & metabolic health
Why the weight moves at midlife, what actually shifts it, and what it costs in muscle and bone.
Why the weight moves to the middle even when the scale holds
Body composition changes at menopause independently of how much you weigh, and that shift is the part that matters.
GLP-1 medicines at midlife: strong evidence, and the part about muscle and bone
The best-evidenced thing in this field, with a specific cost that matters more for women over 45 than for anyone else.

Bone & longevity
The loss that has no symptoms until the fracture, and the few things that slow it.
Bone loss is fastest in the few years around your final period
It has no symptoms until something breaks, and the window where you can do most about it is the one most women spend unaware.
ApoB and Lp(a): the cardiac numbers that change at menopause
Cardiovascular disease is the leading cause of death in women, and the risk profile shifts measurably across the transition.

Training, strength & recovery
Why the training stopped working, and the iron and thyroid numbers behind it.
When training stops working, check iron and thyroid before programming
Two extremely common, extremely treatable findings explain most of it — and neither is on a standard panel.
Muscle after forty: use it or lose it, faster than before
Strength declines faster than mass, power faster still — and power is what catching a stumble requires.

Bloodwork & biomarkers
What each number means, when to draw it, and what it cannot tell you.
“Normal range” and “optimal range” answer different questions
One is built from whoever walked into a lab. The other is a clinical judgment. Knowing which you are being shown matters.
Ferritin: the most useful number missing from your annual panel
Iron deficiency is extremely common in menstruating women, causes exhaustion long before anaemia, and is usually not tested.

Safety & red flags
How people actually get hurt, and the seven warning signs in a telehealth offer.
How people actually get hurt in this field
Not usually by an exotic pharmacological effect. Almost always by one of five ordinary failures.
Seven red flags in a women’s telehealth offer
Patterns that reliably indicate a seller rather than a clinic. We have tried to build the opposite of each one.
Compounded or approved: what the difference actually means for you
“Compounded” is a manufacturing route, not a quality grade — and it is routinely marketed as though it were the opposite.
Research Library
The evidence, including the parts that are missing.
Stem cells, exosomes and peptides are the three things being sold hardest to women in this decade of life. Here is what has actually been published about each of them, what it does and does not show, and which questions are still open — with every paper cited so you can go and read it yourself.
Aethera Women's Lab is not a medical provider and does not practice medicine. Medical services are provided exclusively by independently licensed physicians of our partner physician network and their affiliated professional entities.
Compounded drugs are not FDA-approved and have not been evaluated by FDA for safety or effectiveness.
