How to Improve Fertility and Boost Your Chances of Pregnancy

Trying to conceive can bring hope, excitement, pressure, and a long list of questions. Some people become pregnant quickly. Others need more time, more information, or medical support. Both experiences are common, and neither says anything about your worth or future as a parent.

Fertility is shaped by many connected factors, including age, ovulation, sperm health, general health, timing, nutrition, movement, stress, sleep, and medical history. While no lifestyle change can guarantee pregnancy, small, steady steps can help create better conditions for conception.

This guide is informational only and does not replace medical advice. If you have concerns about fertility, irregular cycles, pain, previous pregnancy loss, or a known health condition, speak to a GP, gynaecologist, fertility specialist, or other qualified healthcare provider.

Fertility health often starts with steady daily habits.

Fertility starts with understanding the factors that affect conception

Pregnancy depends on several things happening at the right time. An egg needs to be released during ovulation. Healthy sperm need to reach the egg. Fertilisation needs to happen, and the embryo then needs to implant in the uterus.

When pregnancy does not happen quickly, it does not always mean something is wrong. Timing alone can make a big difference. Still, understanding the main factors that affect fertility can help you make informed choices.

Age affects egg number and egg quality

Age is one of the strongest natural factors in fertility, especially for people with ovaries. Egg number and egg quality decline over time, with a more noticeable drop from the mid-30s onward. This can make conception take longer and may increase the chance of miscarriage.

Sperm-producing partners can also experience age-related changes. Sperm quality may decline gradually with age, and lifestyle and medical factors can affect sperm count, movement, and shape at any stage of adult life.

Age is not a deadline, and many people do conceive later in life. It does mean that seeking support sooner can be helpful if pregnancy is taking longer than expected.

Health conditions can affect ovulation and implantation

Some health conditions can affect fertility by changing hormone levels, ovulation, the uterus, fallopian tubes, or sperm production. These may include:

• Polycystic ovary syndrome, often called PCOS

• Endometriosis

• Thyroid disorders

• Diabetes or insulin resistance

• Fibroids or uterine polyps

• Previous pelvic infections or untreated sexually transmitted infections

• Low sperm count or poor sperm movement

• Being significantly underweight or overweight

• Autoimmune or chronic inflammatory conditions

  
  

Many of these conditions can be managed. The key is not to guess for months or years if your body is giving you signs that something needs attention.

Lifestyle choices can support or strain fertility

Lifestyle does not control everything, but it can influence hormones, ovulation, sperm health, inflammation, and general wellbeing.

The biggest fertility-related lifestyle factors include:

• Smoking or vaping

• Heavy alcohol use

• Recreational drug use

• Poor sleep

• High stress over long periods

• Very low or very high body weight

• Extreme exercise or too little movement

• Diets low in key nutrients

• Exposure to certain toxins or chemicals at work or home

  
  

The goal is not perfection. The goal is to reduce the things that can make conception harder and build habits that support reproductive health.

Understanding your ovulation cycle can improve timing

Many people focus on the day they think they ovulate, but the fertile window matters more than one single day. Sperm can survive in the reproductive tract for several days, while an egg survives for a much shorter time after ovulation.

For many cycles, ovulation happens about 12 to 16 days before the next period starts. In a 28-day cycle, that may be around day 14, but not everyone has a 28-day cycle. Some people ovulate earlier or later, even when their periods seem regular.

The fertile window usually includes the five days before ovulation and the day of ovulation. Having sex every one to two days during this window can improve the chance that sperm are present when the egg is released.

Signs that ovulation may be approaching

Your body may give clues that ovulation is near. These signs can vary from cycle to cycle.

Look for changes such as:

• Cervical mucus becoming clearer, wetter, and more stretchy

• A slight rise in basal body temperature after ovulation

• Mild pelvic discomfort on one side

• Increased sex drive

• Positive ovulation predictor kits that detect a rise in luteinising hormone

  
  

Ovulation predictor kits can be useful, especially if cycles are regular enough to estimate when to start testing. Basal body temperature tracking can confirm that ovulation likely happened, but it usually does not predict ovulation early enough on its own.

Tracking ovulation can make timing feel less like guesswork.

Irregular cycles deserve attention

If cycles are often shorter than 21 days, longer than 35 days, absent, or very unpredictable, ovulation may not be happening regularly. Irregular cycles can have many causes, including PCOS, thyroid imbalance, stress, weight changes, and perimenopause.

Tracking is helpful, but medical support can identify what is happening sooner. Blood tests, ultrasound scans, and a review of symptoms can give a much clearer picture.

Nutrition can support hormone health and early pregnancy

There is no single “fertility diet” that works for everyone. A balanced eating pattern can support ovulation, sperm health, blood sugar, hormone production, and early foetal development.

A practical approach is to build meals around whole, nutrient-rich foods most of the time.

Choose foods that nourish reproductive health

Aim to include:

• Plenty of vegetables and fruit in a range of colours

• Whole grains such as oats, brown rice, wholewheat bread, and barley

• Protein from eggs, fish, chicken, lean meat, beans, lentils, tofu, or dairy

• Healthy fats from avocado, olive oil, nuts, seeds, and oily fish

• Iron-rich foods such as lean red meat, beans, lentils, spinach, and fortified cereals

• Calcium-rich foods such as yoghurt, milk, maas, cheese, or fortified alternatives

  
  

Folic acid is especially relevant before pregnancy. Many healthcare providers recommend taking 400 micrograms of folic acid daily before conception and during early pregnancy to help reduce the risk of neural tube defects. Some people need a higher dose because of medical history or medication use, so ask a clinician what is right for you.

Balance blood sugar where possible

Stable blood sugar can support hormone balance, especially for people with PCOS or insulin resistance. This does not mean cutting out all carbohydrates. It means pairing carbohydrates with protein, fibre, and healthy fat.

For example:

Instead of only toast

Instead of only fruit juice

Instead of plain pasta

Try wholegrain toast with eggs or peanut butter

Try whole fruit with yoghurt or nuts

Try pasta with vegetables, lentils, chicken, or tuna

Small changes like these can make meals more satisfying and reduce energy crashes.

Be careful with restrictive diets

Very low-calorie diets, extreme fasting, or cutting out whole food groups without medical guidance can disrupt hormones and ovulation. If you have allergies, intolerances, ethical food preferences, or a medical condition, a registered dietitian can help you plan a balanced preconception diet.

Movement helps when it is steady and sustainable

Regular exercise can support fertility by improving circulation, insulin sensitivity, mood, sleep, and general health. It can also help with weight management where needed.

Most people benefit from moderate exercise such as:

• Brisk walking

• Swimming

• Cycling

• Dancing

• Pilates

• Strength training

• Low-impact fitness classes

  
  

You do not need intense workouts to support fertility. In fact, very intense training without enough rest or food can affect menstrual cycles in some people.

A good target is consistency. If you are not active now, start with 20 to 30 minutes of walking on most days. Add light strength training two or three times a week when it feels manageable.

For sperm health, movement matters too. Regular exercise may support healthy testosterone levels, body weight, and circulation. Avoiding heat around the testes can also help, so it may be wise to limit frequent hot baths, saunas, or tight heat-trapping clothing when trying to conceive.

Balanced meals can support energy, hormones, and preconception health.

Stress management matters, but blame does not help

Trying to conceive can become emotionally heavy, especially when months pass without a positive test. Stress is often mentioned in fertility conversations, sometimes in an unhelpful way. Stress alone is rarely the full reason someone is not pregnant, and telling someone to “just relax” can feel dismissive.

Still, long-term stress can affect sleep, sex drive, eating patterns, alcohol use, and cycle regularity. Stress support is not about blaming the mind. It is about helping the whole body cope.

Helpful stress tools include:

• Gentle breathing exercises for a few minutes a day

• Walking outside

• Journalling without judging the feelings that come up

• Yoga, stretching, or meditation

• Time away from pregnancy forums if they increase anxiety

• Counselling or therapy, especially after loss or fertility treatment

• Honest conversations with a partner about timing, sex, money, and expectations

  
  

If sex starts to feel like a scheduled task, try to protect intimacy outside the fertile window. Physical closeness, affection, and communication can reduce pressure and keep connection strong.

Sleep also deserves attention. Poor sleep may affect hormones, appetite, mood, and energy. Aim for a regular sleep routine where possible, with less screen time close to bed and a cool, dark room.

Medical check-ups can find problems early

Regular medical check-ups are one of the most useful steps when planning pregnancy. A preconception visit can help identify health issues, update vaccinations if needed, review medication safety, and discuss supplements.

A healthcare provider may check or discuss:

• Menstrual cycle patterns

• Previous pregnancies or pregnancy losses

• Chronic conditions such as diabetes, high blood pressure, thyroid disease, or epilepsy

• Current medication and whether it is safe in pregnancy

• Sexually transmitted infection screening

• Rubella or other vaccine status where relevant

• Cervical screening if due

• Weight, blood pressure, and general health

• Family history or genetic concerns

• Sperm analysis where there is a male partner

  
  

Some prescription medicines are not suitable during pregnancy, while others are safer to continue than to stop suddenly. Always ask before changing medication.

Know when to seek fertility support

Many couples are advised to seek medical advice after 12 months of regular unprotected sex if the person trying to conceive is under 35. If they are 35 or older, it is usually sensible to seek help after 6 months. From 40 onward, or if there are known issues, earlier advice is often better.

Seek help sooner if there are:

• Very irregular or absent periods

• Known PCOS or endometriosis

• Severe period pain

• Previous pelvic infection

• Repeated miscarriages

• Known low sperm count

• Cancer treatment history

• Previous surgery involving the ovaries, uterus, testes, or tubes

• Difficulty with erections or ejaculation

  
  

Getting support does not mean you are committing to fertility treatment. It means gathering information so you can make clear choices.

Everyday habits that can improve your chances

The small choices repeated often tend to matter more than dramatic short-term changes.

Focus on these foundations:

Stop smoking and avoid vaping where possible. Smoking affects egg and sperm health and can increase pregnancy risks. Ask a healthcare provider about support if quitting feels hard.

Limit alcohol. The safest approach when trying to conceive and during pregnancy is to avoid alcohol. For sperm-producing partners, reducing alcohol can also support general reproductive health.

Use caffeine wisely. Moderate caffeine intake is generally considered acceptable by many pregnancy guidelines, but very high intake is best avoided. Coffee, tea, energy drinks, chocolate, and some medicines can all contribute.

Review lubricants. Some lubricants can affect sperm movement. If you use one, choose a fertility-friendly option.

Protect sperm health. Sperm production takes time, so lifestyle changes may take a few months to show an effect. A balanced diet, no smoking, less alcohol, regular movement, and avoiding heat exposure can all help.

Check environmental exposures. If your work involves pesticides, solvents, heavy metals, radiation, or high heat, ask about protective steps. Do not stop work based on fear, but do get proper advice.

Rest and emotional support are part of a healthier conception journey.

A supportive plan for the next three months

If you feel unsure where to begin, choose a few steps instead of trying to change everything at once.

Try this simple plan:

1. Track your cycle for two to three months

   
   

   Record period dates, cervical mucus changes, ovulation test results if used, and symptoms.

   
   

2. Start a prenatal supplement

   
   

   Choose one with folic acid, or ask a clinician which supplement suits your medical history.

   
   

1. Time sex around the fertile window

   
   

   Aim for every one to two days in the days leading up to ovulation and on the day of ovulation.

   
   

2. Book a preconception check-up

   
   

   Bring questions about medication, vaccines, cycle concerns, past health issues, and when to seek fertility testing.

   
   

1. Choose two lifestyle habits to improve

   
   

   For example, add a daily walk and reduce alcohol, or improve sleep and add more protein at breakfast.

   
   

2. Include both partners where possible

   
   

   Fertility involves eggs, sperm, timing, health, and chance. Shared responsibility can reduce pressure and improve follow-through.

   
   

Pregnancy can take time, even when everything looks healthy. A supportive approach gives you the best chance while protecting your wellbeing along the way. Learn your cycle, nourish your body, keep moving, manage stress with kindness, and get medical advice when it is time. The next best step is often simple: start with what you can do this week, then build from there.
