Today I’m joined by Dr Lynn Burmeister, one of Australia’s most recognised fertility specialists and founder of Number 1 Fertility. Lynn has spent decades at the forefront of reproductive medicine, training under global pioneers and helping thousands of women understand their fertility with clarity and confidence. Lynn breaks down IVF and egg freezing in a way that finally makes sense, simple, honest, science-backed and female-focused.

We cover the full fertility foundation: what women should know in their 20s and 30s, how egg quality really changes with age, the true timelines involved, why preparation matters, and what you can actually expect from both egg freezing and IVF. From AI-graded embryos to gut health, supplements, male factor infertility and the emotional side of the journey, this is a must-listen starter guide for anyone wanting to protect or understand their fertility.

In the episode:

• How Lynn entered the fertility world and how rapidly the industry has evolved
• The shift from day-3 to day-5 embryos and how AI now helps grade embryo quality
• What makes a great fertility clinic (technology, care style, lab quality)
• Why Lynn built a more holistic, patient-centred clinic environment
• When women should consider egg freezing: AMH, AFC and ideal timelines
• Why age 30–35 is the window to seriously evaluate your options
• Common reasons women freeze their eggs (single, career timing, future flexibility)
• Step-by-step egg freezing: testing, injections, collection & recovery
• Ideal egg numbers (why 20 eggs under 35 gives the best chance)
• Emotional + hormonal changes to expect during a cycle
• Lifestyle prep: 90-day optimisation, supplements, diet, alcohol, smoking
• How past drug use or long-term contraception may impact egg quality
• Endometriosis & PCOS: why diagnosis matters before starting treatment
• IVF 101: what actually happens from Day 2 cycle start to embryo creation
• Fresh vs frozen transfers — and when one is better than the other
• Embryo testing: who needs it and why it increases success after 35
• Managing expectations when a “perfect” embryo still doesn’t implant
• Sleep, stress, and lifestyle factors that directly affect egg and embryo quality
• Male fertility: why 50% of infertility is male-factor
• Sperm decline, microplastics, radiation, overheating and environmental toxins
• Practical male optimisation tips (cooling, supplements, lifestyle changes)
• Gut health, inflammation and the vaginal microbiome — and how they affect fertility
• Costs: typical pricing for egg freezing, IVF, storage fees and clinic variations
• Low-cost options, superannuation access and when to invest in higher tech
• Gender selection, multiples, overseas options and why Australia regulates them
• Lynn’s final advice: protect your fertility early — your future self will thank you
