If you’re experiencing changes in sleep, mood, energy, hot flushes, or discomfort during sex, you’re certainly not alone. These changes are common during perimenopause and menopause, and there are several evidence-based options that may support you through this transition.
I’m Jenna, your Nurse Practitioner and menopause educator. This guide helps make sense of the different hormone therapy options available in Australia, how they work, and how to approach treatment in a way that’s safe, informed and tailored to you.
What does “bioidentical” actually mean?
Bioidentical hormones have the same molecular structure as the hormones your ovaries produced before menopause. These include:
Oestradiol (the main form of oestrogen)
Micronised progesterone
Physiologic-dose testosterone (for specific indications)
In Australia, bioidentical hormones are available in two forms:
TGA-approved bioidentical products
These are standardised, regulated medicines (patches, gels, capsules, tablets).
Compounded bioidentical hormones*
These may be considered when:
a person cannot tolerate TGA-approved products
they require an excipient-free option
a specific dose or formulation is needed that is not commercially available
Because compounded products are not TGA-approved and may vary in strength and purity, they are not first-line in Australian and international guidelines.
However, they can be appropriate in selected cases following an individualised discussion of risks, benefits and alternatives.
This means compounded options remain available — just not the default starting point.
*Always discuss risks like inconsistent dosing/purity with your practitioner
Bioidentical, Synthetic and Compounded Hormones – Understanding the Differences
Both synthetic and bioidentical hormones have been used safely for decades and are supported by substantial international research. The best choice depends on symptoms, health history, preferences and individual tolerability.
Below is a simple, AHPRA-compliant comparison of key characteristics, not expected outcomes.
Key Characteristics of Hormone Therapy Options
(AMS, NAMS, NICE, Monash Toolkit — 2024–2025)Individual suitability varies; outcomes are not guaranteed.
Treatment Options in Australia
Depending on your symptoms and where you are in the menopause transition, options may include:
Oestradiol (gel, patch or tablet)
Micronised progesterone
Combined oestrogen–progestin tablets
Low-dose vaginal oestrogen for dryness and discomfort
Testosterone for low sexual desire when clinically indicated
Suitability varies from person to person. Age, medical history, personal risk factors and prior responses to treatment all help guide decision-making.
A simple way to explore your options
Here’s a supportive way to begin:
Track your symptoms for 2–4 weeks.
Book a longer consultation to allow time for discussion.
Bring this newsletter and ask:
“Which option aligns best with my health history and goals?”
Hormone therapy often requires minor adjustments over time to find the right fit.
Non-hormonal choices
Some women prefer non-hormonal options or cannot use hormones. Evidence-based alternatives include:
Non-hormonal medications for hot flushes
Cognitive behavioural strategies for flushes and sleep
Regular vaginal moisturisers and lubricants
Strength training, movement and sleep optimisation
Tracking and reducing personal triggers such as alcohol or caffeine
