What Is IVF? And Why Optimising Your Nutrition Matters
Nutrition by Bec
More couples than ever are turning to IVF (In Vitro Fertilisation) to start or grow their families.
Let’s break down what IVF actually involves, and why optimising your nutrition can meaningfully improve your outcomes.
What Is IVF?
IVF (In Vitro Fertilisation) is a type of assisted reproductive technology (ART) where fertilisation occurs outside the body.
Here’s a simplified overview of the process:
- Ovarian stimulation
Hormone medications are used to stimulate the ovaries to produce multiple eggs in one cycle (instead of the single egg usually released). - Egg retrieval
The eggs are collected from the ovaries via a minor procedure. - Fertilisation
The eggs are combined with sperm in a laboratory to create embryos. - Embryo development
Embryos are monitored for several days as they grow. - Embryo transfer
A healthy embryo is transferred into the uterus. - The two-week wait
If implantation occurs, pregnancy begins.
While IVF supports fertilisation and embryo transfer, it cannot override egg quality, sperm quality, implantation capacity, or the uterine environment. That’s where nutrition and lifestyle play a crucial role.
Why Nutrition Matters in IVF
No. BUT, IVF success isn’t just about creating embryos, it’s about optimising your nutrition at each stage, creating healthy embryos that implant and continue developing.
Your nutritional status influences:
- Egg quality
- Sperm quality
- Hormone balance
- Inflammation levels
- Insulin sensitivity
- Uterine lining receptivity
- Placental development
Simply put, nutrition impacts the chances of falling pregnant and staying pregnant.
Ideally, both partners should optimise their nutrition for at least 3 months before an IVF cycle, as this reflects the sperm development timeline and egg maturation window.
Can Nutrition Guarantee IVF Success?
No. BUT, IVF outcomes are influenced by many factors: age, underlying diagnosis, embryo genetics, and medical variables.
But nutrition is one of the few modifiable factors within your control.
Given the cost of IVF, prioritising your nutrition to improve outcomes simply makes sense.
And while it cannot guarantee pregnancy, it can:
- Improve egg and sperm quality
- Support implantation
- Reduce miscarriage risk
- Improve overall pregnancy health
- Support long-term child health
That makes it worth prioritising.
When Should You Start?
Ideally, nutrition optimisation begins at least 3 months before starting IVF.
However, it’s never too late to improve your nutritional status — even small changes can make a difference.
If you’re investing emotionally, physically, and financially into IVF, supporting your nutrition is one of the most powerful ways to improve your chances.
