Planning Ahead

Currently Trying
You and your partner are actively trying to conceive. You want to do your part properly, not just hope for the best.
Responding to Results
You’ve had testing done or received results that raised concerns. You want something evidence-led, not another generic supplement.

You treat fertility as part of your overall health - something to support consistently, not ignore until there’s a problem.

Frequently asked questions
Who should take a fertility supplement?
A fertility supplement for men is for any man over 18 who wants to take their fertility seriously.
Common scenarios:
- Planning ahead: You're 6-12 months away from trying. You want to start optimising before you need it.
- Currently trying: You and your partner are actively working toward conception.
- Addressing results: You've had testing or have been trying for a while and want to improve sperm parameters.
- Preparing for IVF/ICSI: You want to optimise sperm quality before assisted reproduction.
- Proactive health: You view fertility as part of overall wellness, like fitness or nutrition.
The protocol is designed to support male fertility, sperm function and development at any stage of the journey. Because the best time to support your fertility is before you absolutely need it.
What makes the ODYN Fertility Protocol different to other supplements?
The ODYN Fertility Protocol was designed specifically for sperm health.
It contains clinically relevant doses of key nutrients, rather than broad, low-dose blends.
How long does it take to improve sperm quality?
Sperm cells take roughly74 days(about 2.5 months) to fully mature. This means the changes you make today - whether that's starting supplements, adjusting your diet, or ditching bad habits - won't reflect in your sperm analysis tomorrow or even next week.
You can learn more about it in our Education Hub.
Do fertility supplements for men actually work?
Honestly - it depends.
Sperm health is affected by a lot of factors: age, lifestyle, underlying issues, or medical conditions.
No supplement can promise a specific outcome and anyone who tells you otherwise isn't being straight with you.
ODYN is built around ingredients and doses the research supports. It won't work the same way for everyone. But I believe it gives you the best possible odds.
Start early. Be consistent. Give it a full cycle.

Why is the ODYN Fertility Protocol 3 months?
Sperm take about 74 days to regenerate, so the full 3-month protocol aligns with your body’s natural cycle for sperm development.
When should I start taking a male fertility supplement?
Start the ODYN fertility protocol as soon as possible. Ideally 3+ months before you need it.
Sperm take around 74 days to regenerate from scratch, so we recommend starting the ODYN Fertility Protocol at least three months before you're actively trying to conceive. That gives your body time to respond, and helps support the full sperm development cycle.
If you're already trying: Start now. Every cycle counts, and you should see the full benefits after 3 months of consistent use.
If you're planning ahead: You're making the smartest move possible. Starting early means you've the best chance of optimising your odds of conception when the time comes.
Sperm quality is influenced by stress, age, diet and environment. The earlier you act and make positive changes, the better your odds.
How long should I take a male fertility supplement for?
We recommend taking the ODYN fertility protocol for a minimum of three months. This reflects a full sperm development cycle.
If you're trying to conceive, you should continue it throughout the process. However, due to our high dosages, we recommend consulting a medical professional if you wish to use long term.
Can I take the ODYN Fertility Protocol if we’re trying naturally?
Yes. Most couples conceive naturally, and sperm quality still plays an important role.
The ODYN Fertility Protocol is designed to support male fertility whether you're trying naturally or preparing for assisted reproduction.
Supporting sperm health early can help give you the best possible starting point when trying to conceive.
You can learn more about male fertility in our Education Hub.
Can I take the ODYN fertility protocol if I'm preparing for IVF or ICSI?
Yes. Sperm quality still matters in assisted reproduction, and it doesn’t change overnight.
ODYN is designed to support sperm development over a full cycle, which is why many men choose to take it in the months leading up to IVF or ICSI.
If you’re preparing for treatment, starting earlier gives your body time to respond.
When should I take the ODYN fertility protocol each day?
Take all 7 capsules once daily, ideally with food. Morning, afternoon or evening is fine. Consistency is what matters most. Just find a time that fits your routine.
Can I take the Odyn Fertility Protocol with other supplements or medication?
If you're taking medication or other supplements, we recommend checking with your GP/Medical Professional.
Because the ODYN Fertility Protocol is highly dosed, we don’t recommend taking it alongside other supplements that contain the same ingredients, especially those with high levels of Zinc, Selenium or Vitamin D. Also be mindful of foods naturally high in these nutrients, like Brazil nuts, which are particularly rich in Selenium.
If you have any doubts, please reach out to your medical professional.
Why does the ODYN Fertility Protocol come in two bottles?
The ODYN Fertility Protocol is split across two bottles to deliver exactly what your sperm needs without compromising.
One bottle contains a high-dose L-Carnitine formula, while the second bottle provides a clinical-strength blend including Zinc, Selenium, Lycopene and key vitamins that support sperm health.
By separating the formula, we can dose each component properly without cutting corners or underdosing just to fit it into less capsules. We believe its all about the right ingredients at the right doses.
Still have questions about ODYN?
That's great. It means you are taking this seriously.
