Here's something that surprises most people: sperm take approximately 74 days to fully develop. That means the sperm involved in a conception were being formed more than two months before the moment they were needed. Whatever was happening in that person's body — the food they were eating, how much they were sleeping, whether they were stressed — was shaping those sperm the entire time.

This is why preconception health for all partners matters, and why the conversation about fertility so often misses half the picture.

What actually affects sperm quality?

Sperm quality is measured in a few key ways: count (how many there are), motility (how well they swim), and morphology (their shape). All three are influenced by lifestyle factors — most of which are within your control.

• Heat: Sperm are produced at slightly below body temperature. Prolonged heat exposure — hot tubs, saunas, laptops on laps — can temporarily reduce sperm count and motility. This effect is reversible but takes time.
• Nutrition: Antioxidant-rich foods (leafy greens, berries, nuts) help protect sperm from oxidative damage. Zinc and folate are particularly important — both found in legumes, seeds, and whole grains.
• Alcohol: Regular heavy drinking is associated with lower sperm count and poorer morphology. Reducing alcohol in the months before trying to conceive is one of the most evidence-backed things a person can do.
• Smoking: Both tobacco and cannabis have been associated with reduced sperm quality. The evidence on cannabis is growing — it's worth being cautious.
• Stress: Chronic stress affects hormone levels, which in turn affects sperm production. This doesn't mean occasional stressful periods are catastrophic — but sustained high stress over months can have a real impact.

The three-month window

Because the sperm development cycle is roughly 74 days, changes you make today won't fully show up in sperm quality for about three months. This is genuinely useful information — it means that if you're planning to start trying to conceive in the spring, the changes you make in January matter.

What about egg health?

Egg health follows similar principles — antioxidant-rich nutrition, reduced alcohol, managing stress, and adequate sleep all support egg quality. The timeline is slightly different (egg development takes longer), but the overlapping message is the same: what both partners do in the months before trying to conceive matters enormously.

This isn't about being perfect. It's about giving your body — and your future pregnancy — the best foundation possible before you need it.

Miscarriage is one of the most common experiences in reproductive health — and one of the least discussed. The silence around it doesn't protect people. It isolates them. When a miscarriage happens, many people immediately ask what they did wrong. The answer, in the vast majority of cases, is nothing.

What causes most miscarriages?

Approximately 50–70% of early miscarriages are caused by chromosomal abnormalities in the embryo — random errors in cell division that have nothing to do with anything either parent did or didn't do. The body, in most cases, is doing exactly what it's designed to do: recognising that a pregnancy isn't developing as it should and ending it early.

This is not a comfortable way to frame it. But it is an accurate one, and for many people, understanding the biology is part of what helps them begin to release the guilt.

Why we don't talk about it

The traditional advice to wait until 12 weeks to share pregnancy news was originally practical — it's the point at which miscarriage risk drops significantly. But it has had an unintended consequence: people experiencing early miscarriage often go through it almost entirely alone, without the social support they'd receive for any other loss.

When public figures began speaking openly about their miscarriages, many people reported feeling seen for the first time. That response says everything about how much this silence costs people.

What you can actually do

• Optimising preconception health — nutrition, reducing alcohol, managing stress — can support a healthy pregnancy, but cannot prevent chromosomally-caused miscarriage.
• Recurrent miscarriage (three or more) warrants investigation by a specialist. There are often identifiable and treatable causes.
• Give yourself permission to grieve. A miscarriage is a loss, regardless of how early it occurs or how the pregnancy came to be.
• You do not have to wait a specific amount of time before trying again — your healthcare provider can advise based on your individual circumstances.

Folic acid is probably the most well-known preconception supplement. It's also one of the most commonly misunderstood. Most people have heard they should take it during pregnancy — but the timing, dosage, and who should be taking it are all frequently gotten wrong.

Why timing matters so much

The neural tube — the structure that develops into the brain and spinal cord — forms in the first 28 days of pregnancy. In most cases, that's before many people even know they're pregnant. This is why folic acid needs to be taken before conception, not just after a positive test.

Current recommendations suggest starting folic acid supplementation at least one to three months before trying to conceive. For people with certain risk factors, higher doses may be recommended — your healthcare provider can advise.

What about the other partner?

Folate — the natural form of folic acid — plays an important role in sperm DNA synthesis and repair. Research suggests that adequate folate intake in people who produce sperm is associated with lower rates of sperm chromosomal abnormalities. While the evidence is less definitive than it is for neural tube defect prevention, the case for all partners taking a folate-containing supplement is growing.

Food sources vs. supplements

Folate is found naturally in leafy greens, legumes, citrus, and fortified foods. However, the synthetic form (folic acid, found in supplements) is actually more bioavailable — meaning it's absorbed and used more efficiently by the body. For preconception purposes, a supplement is recommended in addition to a folate-rich diet, not instead of one.

• Good food sources of folate: spinach, lentils, black beans, asparagus, broccoli, oranges, and fortified cereals.
• Look for: supplements labelled as folic acid or methylfolate (the active form, which some people absorb better).
• Check your prenatal: if you're taking a prenatal vitamin, it almost certainly contains folic acid — check the label to confirm the dose.

The bottom line: folic acid is one of the most evidence-backed, low-risk, high-impact things you can do in the preconception period. Start early, take it consistently, and make sure both partners have considered their folate intake.
