Robert Wadlow is known as the tallest man who ever lived.
Gigantism and acromegaly are rare conditions where a benign tumour causes excessive production of growth hormone (GH), which stimulates the growth of the skeleton and all tissues in the body.
Men might think about sex more often than women, but they also think more about food and sleep, which probably means they’re just more needs-based in general.
Are men hot-blooded, sex-driven creatures that think about sex every seven seconds? Not quite.
IVF is still an expensive, invasive process that can have significant side-effects.
Early studies suggest a process called advanced in-vitro maturation may be able to treat infertility without women needing to inject themselves with high doses of hormones for several weeks.
Some women breeze through perimenopause and never have a symptom, whereas others have a horrid time.
Every woman who reaches midlife will experience menopause when her ovaries eventually run out of eggs. So what's happening with her hormones?
Do we accept attraction and attachment the way they are, or find ways to intervene?
"Love drugs" have their risks, but are also potentially liberating, so people must be free to make their own choices about what works best for them.
There’s a battle for resources going on in there.
Embryos greedily want more resources than their fair share. New research investigates how early in evolution their hormonal tactics arose.
Fathers experience an equal rise in the bonding chemical oxytocin as mothers do when interacting with their infant.
What are the hormones that cause cravings during pregnancy?
Multiple hormones produced by the mother, placenta and the foetus drive and coordinate the amazing biological changes and development of the baby that occur with conception, foetal growth and birth.
Testosterone fuels risk-taking behaviour – new research shows this leads to bigger wins for men but also much bigger losses.
Just do it.
There really is no reason to be a wallflower. Dancing could lower your pain threshold, help you make friends and even find a romantic partner.
Whether or not you feel inclined to eat depends on the balance of the activity between two sets of neurons.
Our bodies have a complex system to control food intake, driven by hormones. Hormone levels also change when we gain and lose weight.
Here’s a clue: what you eat is just as important as the size of your meal.
We’ve all done it: enjoyed a delicious meal only to nod-off in a comfy chair for a while. A habit for some but unavoidable for others, what is it about food that can make us so sleepy?
The activities we do during the day – from having a fight with a partner to using our iPhones at night – also affect our hormone levels and, in turn, our quality of sleep.
Sleep allows many of our hormones to replenish so we have the optimal energy, immunity, appetite and coping ability to face the day’s highs and lows.
The hormone irisin is one of the things that makes exercise good for us.
Scientists in the US have found that a feel-good exercise hormone called irisin does indeed exist in humans, putting to bed long-disputed claims that it is a myth.
There are many reasons why some people get very grumpy when they haven’t eaten for a while.
"Hangry" is an amalgam of hungry and angry that describes the distinct grumpiness that some people experience when they haven't eaten for a while. Ring a bell?
Tsimane hunter with prey after a successful hunt. How are his hormones responding?
Levels of a male sex hormone known to influence aggression and a "love" hormone that promotes bonding both rise in traditional hunters headed home after the kill. What's going on?
Light from electronic devices can alter the quality of sleep our quality.
While many of these devices, especially e-readers, seem harmless enough, the light they emit may affect our sleep patterns and leave us feeling tired the next day.
The earlier you begin treatment the better.
Hair loss is no longer an inevitable march to baldness. Medical advances over recent decades mean male hair loss can be treated. And it need not break the bank. The cause of male pattern baldness is well…
Research into how humans choose a mate is often guided by evolutionary theory: because people’s choice of mate is assumed to have consequences for reproductive success, it must therefore be subject to…
