Egg quality is often used as a reason IVF fails, without any clear evidence.

As age advances, statistically chromosome abnormalities increase and IVF doesn’t help with that. This mama had already been through 2 unsuccessful IVFs and the feedback from her clinic was pointing at her eggs and her age.  Their solution was donor eggs, hers was to look elsewhere.

This couple started working with Now Baby just after she had turned 41 and their second IVF had failed. They both had fertility testing and their secondary infertility was deemed unexplained, so she felt there was nothing wrong medically but her blood sugar reading, Hba1c was high, so she knew there was insulin resistance. What she hadn’t been aware of was the insulin sensitivity plays a role in both egg quality and embryo implantation.

Life had got busy for both herself and her husband after their first child was born. Balancing fulltime jobs and childcare was challenging and previous healthy habits had disappeared in the chaos. Getting their daughter out the door before the traffic was a joint effort and the easiest thing was to skip breakfast until she got to work. What she hadn’t realised was that this single habit was undermining her chance of growing her family. Breakfast is the key meal for supporting blood sugar balance throughout the day and the timing of it matters.

Neither of them focused any of their meals, besides dinner, on protein, so getting a full 95g daily made a big difference. Coffee fuelled afternoon slumps were gone, takeouts instead of homecooked were unnecessary because meals were prepped at the weekends so time and decision fatigue were no longer motivators. The protocol balanced everything, protein, anti-oxidants, minerals, all built into easily available local ingredients.

I wish I had known about this option sooner

Following the Now Baby Over 40 Fertility Nutrition Protocol meant making some habit changes for her. Herself and hubbie sat down and discussed how best to manage this, agreed a plan together where breakfast was prepped the night before so that it was ready in the morning before leaving for work. It took just 6 weeks for it to work. After spending thousands on invasive and unsuccessful treatments she was glad she made the decision to reject donor eggs and support the process naturally.

When you are over 40 and trying to grow your family, your age is often given as the reason your risk of a chromosome abnormality is higher.

That explanation stops at the number, as though the number itself decided the outcome. It does not.

Chromosome abnormality is a result of biology, not age, and this biology runs on energy. Each egg contains roughly 100,000 mitochondria — the highest number of mitochondria found in any cell type in the human body, providing the massive energy supply required for fertilisation and early embryonic growth. Every egg preparing to ovulate depends on its own mitochondria to separate its chromosomes correctly. Over 40 is when that energy system comes under more strain.

Your internal energy system decides if life is possible now, before conception, inside the egg that is maturing this cycle.

See how you can support this process now.

The Machinery That Separates Your Chromosomes

An egg begins with paired chromosomes and has to divide them precisely in half during the final stage of maturation, ending up with exactly one copy of each — a division process called meiosis. Meiosis depends on a structure called the meiotic spindle, whose job is to attach to every chromosome and pull the pair apart cleanly, sending one copy to the egg and discarding the other. When an attachment fails, a chromosome can end up on the wrong side of that divide, leaving the egg with one too many or one too few — an error called nondisjunction.

The spindle itself is built fresh each cycle, but the mitochondria powering it originated before you were born and carry accumulated wear from decades of energy production. That accumulated wear is what makes them less able to keep pace with repair as you move through your 40s, producing energy less reliably and leaving the spindle’s attachments to chromosomes more error-prone as a result — which is why the proportion of eggs carrying the wrong number of chromosomes rises across this decade.

The Energy an Egg Needs Before It Can Mature

Separation work runs entirely on fuel. An egg preparing to ovulate has to complete meiosis. Chromosome alignment, spindle assembly, the physical division of the cell — every stage runs on energy made by the mitochondria inside the egg, since egg and early embryo development depends directly on the energy mitochondria produce. That production is not constant. Live measurements of maturing mammal eggs show energy output surges at specific points tied to the stages of division. The mitochondria supplying it have to be working reliably at exactly the moments the egg needs them most.

Producing that energy also takes fuel from outside the egg. The surrounding follicle — the fluid-filled structure the egg develops inside — supplies glucose, fats and amino acids, which the mitochondria inside the egg convert into usable fuel. That conversion depends on B-vitamins too, found in wholegrains, eggs and leafy greens. A body running on inconsistent fuel — skipping breakfast, going five or six hours without eating, replacing meals with coffee — is asking the follicle to build that supply out of an unpredictable delivery. An unpredictable supply doesn’t give the mitochondria what they need at the exact moments division requires it, which is what makes the spindle’s attachments more error-prone in the first place. That inconsistency may repeat cycle after cycle, for the 90 days before ovulation.

Mitochondria at the Moment of Fertilisation

Energy demand continues past ovulation, into fertilisation itself. When a sperm reaches the egg, fertilisation triggers a rise in calcium inside it, and that calcium signal is what activates the egg and drives the energy demand of completing the final stage of division. The same mitochondria that powered maturation are now doing a second job — supplying the surge of energy that response requires.

Mitochondria also do quality-control work at this stage, clearing damaged components and maintaining the membrane function energy production depends on. An egg arriving at fertilisation with an already-strained energy supply is asking a system under pressure to do this work too.

What This Means for Your Embryo’s First Days

Your embryo cannot make a new energy supply of its own until a later stage called embryonic genome activation, when its own genes switch on and take over.

Whatever energy reserve the egg carried into fertilisation is what the embryo has to work with through these earliest divisions. A shortfall here can stop a division entirely.

These first divisions also depend on specific nutrients, not just energy. Folate, and vitamins B6 and B12, support the epigenetic processes already active at this stage — the chemical tagging that switches genes on and off as the embryo’s own genome takes over, with folate found in leafy greens, legumes and liver, B12 in animal foods such as meat, fish, eggs and dairy, and B6 in poultry, fish and potatoes. That work is underway before you would ever know a pregnancy exists.

Sperm Depend on the Same Energy System

Sperm mitochondria provide the energy for movement and for the changes a sperm must complete before it can fertilise an egg. Mitochondrial function is also connected with sperm motility and the integrity of the DNA it carries.

A standard semen analysis checks count, movement and shape. It does not show whether the DNA inside the sperm has been fragmented by oxidative stress during development. Higher sperm DNA fragmentation is linked with a lower chance of pregnancy and a higher risk of miscarriage after IVF or ICSI.

Sperm cannot complete most DNA repair for itself. After fertilisation, it relies partly on repair machinery supplied by the egg, and that capacity becomes less effective with maternal age. The egg developing after 40 may therefore reach fertilisation carrying its own energy demands and DNA repair work created by the sperm.

His preparation matters before that point. Dietary patterns built around fish, poultry, whole grains, vegetables and fruit are associated with better semen quality, while diets higher in processed meat, saturated and trans fats, sugary drinks and sweets are associated with poorer semen quality.

This is why fertility preparation over 40 belongs to both partners. Supporting sperm development before conception reduces the avoidable burden carried into fertilisation instead of leaving the egg to manage both sides of the process.

Why One Supplement Can’t Do This Job

CoQ10 supports one part of the mitochondrial energy chain. NAD+ supports enzymes involved in energy metabolism and cellular repair. NAC supports the antioxidant system that protects mitochondria from the oxidative damage energy production itself generates. Each plays a real, specific role — but none of them creates the steady fuel supply that egg and sperm development actually run on.

What determines whether an egg or a sperm cell has the energy this process demands is partly whether meals across the day reliably deliver that fuel, over the 90 day development window — not which supplement gets added. Gaps in that supply can add another constraint during maturation, fertilisation and the embryo’s earliest divisions — stages that already depend on tightly coordinated cellular processes.

Put Your Biology Ahead of Your Age

Your fertility success depends on chromosome separation, energy production and DNA repair capacity.

Your age was never the defining factor — your biology is.

That biology is actively maturing your next egg. The Now Baby Over 40 Fertility Nutrition Protocol coordinates the energy, protein, fats and micronutrients this development window draws on across the full 90 days.

Being over 40 increases the statistical risk that an egg will contain the wrong number of chromosomes. But age is not the only risk factor acting on that egg. During the months before ovulation, the egg develops within a metabolic and nutritional environment influenced by factors you can change. You cannot change your age, but you can change important conditions surrounding the egg you may conceive with.

Advanced maternal age is a risk category, not an assessment of your egg

Advanced maternal age tells you when chromosome abnormalities, miscarriage and difficulty conceiving become more common across a population.

It does not examine the egg developing in your ovary now.

Your age cannot tell you whether the egg released in your next cycle will contain the expected number of chromosomes. It cannot tell you whether that egg will fertilise, whether an embryo will continue developing or whether you will become pregnant naturally.

The higher risk after 40 is real. But a higher proportion of eggs with chromosome abnormalities is not the same as every egg having a chromosome abnormality.

Natural conception depends on the individual egg and sperm involved in that conception.

Current research explains what happens behind the age statistic

The phrase “age-related egg quality” can make it sound as though an egg simply becomes old while waiting inside the ovary.

The biology is more active than that.

An egg develops inside a follicle, supported by the cells surrounding it. These cells process glucose and fats, supply amino acids and help provide the mitochondrial energy and antioxidant protection needed as the egg matures.

The egg must also organise and separate its chromosomes accurately. An error during chromosome separation can leave the egg with too many or too few chromosomes. This may prevent fertilisation, interrupt embryo development or contribute to miscarriage.

A 2025 review of follicular metabolism, egg aneuploidy and ovarian ageing connects age-related chromosome risk with changes in:

• glucose metabolism;
• lipid metabolism;
• amino acid metabolism;
• mitochondrial energy production;
• oxidative stress and antioxidant protection.

These processes become more vulnerable with ovarian ageing. They also continue to depend on the metabolic and nutritional environment surrounding the developing egg.

That is the part of advanced maternal age advice that is often missing. You may be told that chromosome risk rises after 40 without being told that the biological processes behind that risk still have nutritional requirements.

The older egg also has DNA repair work to do

The egg’s work does not end when its own chromosomes have separated.

After fertilisation, the egg must attempt to repair DNA damage carried by the sperm in the earliest stages of embryo development. Its ability to do this depends on the repair capacity developed within the egg before conception.

Ovarian ageing can affect this repair capacity in several connected ways:

• important DNA-repair proteins become less available;
• oxidative stress creates more damage within the egg itself;
• mitochondrial dysfunction can reduce the energy available for repair;
• accumulated cellular damage increases the demands placed on the remaining repair machinery.

The egg can repair some DNA damage carried by sperm, but this capacity is limited and appears to decline with maternal age.

The nutrition available while the egg develops therefore matters beyond maturation and chromosome separation. It also supports the energy and antioxidant resources the egg may need to repair sperm DNA after fertilisation.

Maternal and paternal age interact after fertilisation

Age-related fertility risk does not belong to the woman alone.

As men age, oxidative stress within the reproductive system tends to increase while antioxidant protection and DNA-repair activity during sperm production become less effective. This contributes to higher sperm DNA fragmentation and a greater chance that the fertilising sperm will carry damaged DNA.

Sperm DNA damage generally rises with age. Smoking, excess weight, poor diet, heat and environmental exposures can add further avoidable damage throughout the reproductive years.

A satisfactory semen analysis does not assess DNA integrity. It measures the number, movement and appearance of sperm in one sample. It cannot show how much DNA damage the fertilising sperm may carry, and the result can change as new sperm are produced.

After fertilisation, these two age-related vulnerabilities meet: the sperm may bring more DNA damage while the older egg may have less capacity to repair it before the embryo’s first cell division.

Higher sperm DNA damage has been associated with a longer time to pregnancy, reduced fertilisation, disrupted embryo development and an increased risk of miscarriage.

For natural conception over 40, fertility success depends on supporting the older egg’s repair capacity while reducing the avoidable sperm DNA damage it may have to repair.

Your daily nutrition becomes part of the biological picture

Egg maturation, chromosome separation, DNA repair and sperm development depend on a reliable supply of energy, protein, fats and micronutrients.

Protein supplies amino acids used to build enzymes, cellular structures and antioxidant compounds. Fats contribute to cell membranes, energy metabolism and signalling. Glucose provides energy, while fibre and the way meals are combined help regulate its delivery. Vitamins and minerals are required by the enzymes involved in energy production, DNA synthesis, antioxidant defence and cellular repair.

These requirements have to be met repeatedly during development.

A low-protein breakfast, long gaps without food, coffee replacing meals or most of the day’s protein arriving at dinner can leave energy and amino acid availability poorly distributed across the day.

Metabolic stability depends on when you eat, how much protein you consume and how protein, fibre, carbohydrates and fats are combined.

CoQ10 and fertility supplements can provide individual nutrients. They cannot create that metabolic stability or compensate for nutritional gaps across egg and sperm development.

After 40, supplements without targeted nutrition leave much of the biology identified by the research unsupported.

Natural conception over 40 is not a monthly lottery

You may have been told that natural pregnancy now depends on waiting for a “good egg”.

That turns every cycle into another month of hoping, while the egg and sperm for future cycles continue developing without a targeted preparation plan.

During that development, mitochondrial energy, antioxidant protection, metabolic stability, protein and amino acid availability and avoidable sperm DNA damage remain modifiable.

These are the risk factors you can begin addressing while continuing to try naturally.

Why starting today matters after 40

The egg and sperm that may create your baby are developing now. The egg progresses through months of follicle development before ovulation, while new sperm take approximately three months to develop.

That makes the next 90 days a defined biological window in which to support:

• follicular metabolism;
• mitochondrial energy production;
• chromosome separation;
• antioxidant protection;
• the egg’s DNA-repair resources;
• sperm development and DNA integrity;
• fertilisation, implantation and early embryo development.

Knowing that these processes matter is only useful if you have a practical way to support them every day.

The Now Baby Over 40 Fertility Nutrition Protocol brings the nutritional and metabolic requirements identified by this research into one complete 90-day system for both partners.

It coordinates support for follicular metabolism, chromosome separation and the older egg’s DNA-repair capacity with targeted preparation for sperm development and DNA integrity. That preparation continues through fertilisation, implantation and early embryo development.

The protocol gives you the precise daily structure to put this research into practice, rather than trying to assemble a plan from supplements, conflicting advice and isolated dietary changes.

This mama was 43 and had been trying for her first baby for more than two years.

She had experienced an early miscarriage the previous year and was nervous about becoming pregnant again. The positive test she desperately wanted would also bring the fear of another loss.

After two unsuccessful months of Clomid, she began her third round at the same time as the Now Baby Over 40 Fertility Nutrition Protocol.

She had been told any pregnancy would be high risk

She was taking medication for high blood pressure and had a high BMI. She had been warned that her blood pressure, weight and age would make any pregnancy high risk.

Her work as a nurse added another challenge. She worked shifts, ate very little protein and drank up to three cans of Coke Zero each day. The small amount of water she drank was flavoured with a cordial containing endocrine-disrupting chemicals.

She had no idea that her daily diet could affect the metabolic and nutritional environment in which an egg develops or the resources available during the earliest weeks of pregnancy.

After more than two years of trying, an early miscarriage and two unsuccessful rounds of Clomid, she did not appear to have much in her favour.

Yet.

Her third round of Clomid ended differently

After completing that third round, she sent this message:

“Hi Claire,

Want to let you know I did a pregnancy test over the weekend & it’s positive. Excited and nervous at the same time.”

She believed the change in her diet had made a difference. She continued following the protocol while she waited for her 12-week scan.

When the scan reassured her that the pregnancy was progressing, she recommitted to the diet for the rest of her pregnancy. She was keen to support her body and minimise the pregnancy complications she had been warned about.

She also moved away from shift work, giving her body a more consistent routine in which to rest, eat and nourish her growing baby.

She welcomed her first baby at 44

Age over 40. High BMI. High blood pressure. Shift work. A previous miscarriage. More than two years of trying.

These were genuine risk factors, but they were not the end of her story.

At 44, she welcomed a healthy baby boy.

The Now Baby Over 40 Fertility Nutrition Protocol gives you a targeted 90-day structure for the period in which the egg and sperm are developing. It supports the protein, nutrient and metabolic requirements behind chromosome separation, fertilisation, implantation and early pregnancy—so age is not the only part of your fertility being considered.
