Quiz | Get to know your hormones

Get to know your hormones - Quiz

Your hormones can have a big impact on your overall health, so it's helpful to know a bit more about them. Take the quiz and test yourself – do you know your hormones from A to Z?

  1. Your hormone levels affect more than your reproductive health and fertility.

    Hormones are chemical messengers. They are like your body’s personal courier service, carrying important information from one organ to another. For women, not only do they control periods, fertility and menopause, but hormones also have a powerful influence on mental health, brain chemistry, skin health and more.

  2. The female hormone progesterone has effects in the brain.

    Progesterone affects receptors in the brain but can have different effects in different women. In some women it has a soothing effect, in some it can cause irritability and for many women changes in progesterone make no noticeable difference to how they feel. Levels are naturally low in the first half of a typical cycle, but then rise after ovulation and plunge before the monthly bleed.

  3. Researchers have pinpointed the cause of PMS (premenstrual syndrome).

    Good-quality research into PMS has only happened in recent years and the science is still far from crystal clear. Once thought to be due to low progesterone levels, more recent research has revealed it may be due to a sensitivity to an offshoot hormone of progesterone called allopregnanolone. The sum-up? Watch this space!

  4. Oestrogen protects your skeleton.

    The hormone oestrogen is essential for healthy bone. When oestrogen levels decrease, such as in menopause, bones are at a much higher risk of becoming brittle and breaking (a condition known as osteoporosis).

  5. When you have a hot flush – a common symptom of menopause – your core body temperature rises 1-2 degrees.

    A hot flush can feel like an extreme change in temperature, but your core body temperature (the temperature inside your body) will not change or rise above the normal 36-37°C. Where temperature does change is in your skin. Hot flushes can increase skin temperature by up to 2 degrees, and occur due to changes in blood flow and fluctuating hormones.

  6. Oestrogen may increase your chances of fighting off the 'flu.

    A recent study found that oestrogen can increase your chances of fighting off the 'flu virus. This may mean that you have more protection in the middle of your cycle – commonly around day 14 – when oestrogen naturally peaks. Plus, the oestrogen in prescriptions such as the Pill and MHT (menopause hormone therapy, formerly called hormone replacement therapy) may be giving women some added flu-fighting benefit.

  7. Testosterone is a male-only hormone.

    You may think of testosterone as being a male-only hormone, but it also plays a big role in women’s health. Science has cemented its role in the female sex drive, energy and motivation, but recent research shows that keeping levels healthy can result in improved memory, learning and better brain health.

  8. Female hormone levels and body fat levels are connected.

    The female body requires a certain percentage of body fat to be able to ovulate (release eggs), have periods and become pregnant. If a woman’s body fat level falls too low – such as in athletes or women who do intense exercise – periods and ovulation can stop. If body fat levels are too high (such as in overweight or obese women) the hormones oestrogen and oestrone are typically higher as well, increasing the risk of hormone-related cancers such as breast cancer.

  9. There is more than one type of oestrogen.

    Women’s bodies make three main types of oestrogen. Oestradiol is the most potent form of oestrogen and the main type of oestrogen found in premenopausal women. Oestriol is a weaker oestrogen and mainly found during pregnancy. Oestrone is another weak oestrogen and is the oestrogen found in postmenopausal women.

  10. The moon affects your menstrual cycle.

    In folklore, the menstrual cycle has strong links to the moon or lunar cycle and this is likely because they’re about the same length – a ‘typical’ menstrual cycle is 28 days and a lunar cycle is 29.5 days. Outdated research from the 1980s, on whether the two cycles link up, produced some interesting but conflicting results. However, more recently, a 2013 study tracked 74 women’s cycles for a full year and found no link between the two.

  11. Nice work!

PMS & nutrition

If there was one magic nutrient that could cure all cases of premenstrual syndrome (PMS), chances are we would have heard of it by now. Unfortunately, the research on PMS and nutrition is in short supply, often poor quality and produces conflicting results. However, here is a sum-up from our experts of what we do know:
  • Drinking alcohol increases your risk of PMS – heavy drinking especially so.
  • A healthy body weight may be an important factor in managing PMS symptoms.
  • One of the better-researched areas in PMS and nutrition is calcium supplements. Studies have found they may improve PMS-related fatigue, appetite changes, anxiety and depression.
  • Caffeine intake (from coffee, tea, etc) is not linked with developing PMS, even with a higher intake of 4 cups a day.

Happy hormone slice

B vitamins are needed to keep your hormonal and mental health in balance, and this nut and seed slice is choc-full of Bs!

As well as doing a million and one tasks in a day, your brain is in charge of making ‘happy hormones’ – natural chemicals that can ward off depression, anxiety and decrease pain. The B vitamins are a group of nutrients that are essential to this task.

Science suggests that having a short supply of happy hormones is a key to the mood-based symptoms of PMS, such as increased stress, worry, depression and anxiety.

So here’s a delicious recipe that’s choc-full of vitamin Bs and includes raw cacao – because who doesn’t crave chocolate premenstrually? As a bonus, raw cacao is higher in the muscle-relaxing mineral magnesium, often used in treating PMS, for added ahhh-factor!

'Safety first' for natural medicines

The herbal medicine Vitex agnus-castus, also known as Chaste tree, has been shown in clinical trials to be an effective treatment for PMS. However, it's important to know that over-the-counter herbal products can differ a lot in terms of quality. And just because it's 'natural' does not mean it is safe for you. This herbal medicine, and all herbal medicine, should only be prescribed under the guidance of a qualified health practitioner appropriately trained in herbal medicine.

Spotlight on... bioidentical hormones

In recent years, bioidentical hormones have gained popularity as a more ‘natural’ alternative to menopause hormone therapy (MHT) – formerly known as hormone replacement therapy (HRT) – for treatment of menopausal symptoms. However, the facts may surprise you.

Perimenopause: the change before 'The Change'

One experience that can be a very clear example of hormonal imbalance is perimenopause. Known as the beginning of the journey to menopause, perimenopause begins as a woman’s ovaries begin to wind down and stop releasing eggs. It usually begins in a woman’s 40s, but occasionally can start in a woman’s 30s.

Like any health issue, perimenopause is different for every woman. For some it may last one year, for others 10. And symptoms can vary greatly from woman to woman.

If you are troubled by symptoms, rest assured that you don’t need to put up with them. Speak to your doctor about what treatments may be right for you.


In this segment from ABC Radio's 'Explain This', Dr Sonia Davison joins comedian, Jean Hailes ambassador and guest presenter Nelly Thomas to explain what menopause is, how it’s identified and the treatment options available to those experiencing it.

It's all about balance

“Don’t do too much but definitely don’t do too little,” advises Jean Hailes hormone specialist Dr Sonia Davison, on physical activity levels. “For hormone health it’s all about balance. Too much or too little exercise will affect hormone production and general body functioning.”

For most women, the sweet spot starts around 150 minutes of moderate physical activity per week (that's about 20 minutes a day) and goes up to 300 minutes per week, according to the Australian National Physical Activity Guidelines.

Survey stats on physical activity

Happily, most women who completed our national survey – more than 70% – reported doing at least two hours of moderate physical activity each week. Women aged 66-79 were most likely to clock up at least two hours a week (75.6%), while women aged 36-50 were least likely (64%).

Following the physical activity guidelines can improve hormonal health in more ways than you can count. But some of the big benefits of physical activity include the following:

  • A 25% reduction in breast cancer risk
  • In women with polycystic ovary syndrome (PCOS), physical activity and weight loss can restore the regularity of menstrual cycles and ovulation
  • Increasing your muscle mass through exercise can help control your blood sugar levels and improve how the hormone insulin works in your body
  • It’s an effective stress-buster and may help to manage PMS – recent research found that high stress levels mid-cycle worsens PMS symptoms
  • Studies show that regular exercise can aid women going through menopause by improving quality of life and increasing feelings of happiness.
Real women, real advice

“Find a type of exercise that’s right for you, and remember this can change as we get older. I am not quite as active as I used to be, but a daily walk and a couple of sessions on the exercise bike is easy to fit into my week – and easier on my joints!”
