How to increase fertility in men

When talking about fertility, the main focus is usually on women, as they are the ones who get pregnant. However, it’s just as important for men to look after themselves when trying to conceive.

How to increase fertility in men

When talking about fertility, the main focus is usually on women, as they’re the ones who get pregnant, but if you’re going through IUIICSI or IVF, it’s also important to improve sperm quality. Having good quality sperm doesn’t only increase its chances to fertilise the egg – it can also reduce the risks of miscarriage, as the woman’s body could eventually reject an embryo with faulty DNA. 

Read our guide to discover what are the biggest factors affecting the quality of sperm and how to increase fertility in men.

The main factors affecting sperm quality are:

– Genetics

– Toxins (smoking, alcohol, recreational drugs, sugar, processed foods)

– Increased testicular temperature

– Infections (often asymptomatic)

Read on to find out more about improving sperm quality and how to increase fertility in men.

How to increase fertility in men

There are some lifestyle changes men could take to improve their sperm quality and increase their fertility. 

Sperm temperature

The reason male testicles are outside their bodies is that sperm needs to be kept at a lower temperature than the rest of the body, otherwise, it loses its motility and viability. If you work in a hot environment, take regular breaks to cool down, or if you’re working in a seated position, make sure to stand up and move around once in a while.

Avoid wearing tight clothing and underwear, as it keeps testicles closer to the body and increases their temperature. If you’re using a laptop, keep it on a desk or table rather than on your lap as the heat from your legs will also slowly heat up your testicles.


A balanced diet and maintaining a healthy body weight are very important for keeping the sperm in good condition. Make sure to include enough of these fertility-boosting nutrients in your diet:

– Protein – lean meat and poultry, eggs, pulses, nuts and seeds

– Amino acids – dairy, meat, eggs, seafood, quinoa and buckwheat

– Antioxidants – dark chocolate, blueberries, strawberries, artichokes, kale

– Healthy fats – nuts, avocado, olive oil, chia seeds

To increase fertility, men should introduce regular exercise to their routine. If you are overweight, you should try to lose weight as it could lower your chances to have a baby – read more about how weight affects fertility here.


There are supplements that men can take to help increase fertility such as:

– Omega 3 – DHA, an omega 3 fatty acid, found in marine fish such as tuna and salmon, helps to increase sperm quality and motility.

– Selenium – free-oxidising radicals can cause up to 40% of sperm damage, so taking selenium is vital to protect the sperm, reduce clumping, and abnormalities and increase motility.

– Zinc – an antioxidant that plays a big role in sperm health. Zinc boosts motility and helps to remove excess oestrogen from the body (high levels of oestrogen are linked to low sperm count), and is commonly lacking is most people’s diets.

– CoQ10 – a powerful antioxidant helping to protect the sperm and increase its motility.

– Vitamin B12 – this important vitamin can help to increase the sperm count.

– Folate – helps to boost sperm health.

Male hormonal imbalance

High levels of oestrogen lower fertility-boosting testosterone and can lead to erectile dysfunction and decreased sperm count, libido and seminal fluid. A high fibre and liver-supporting diet is crucial to help the body clear any excess hormones – increase your intake of green leafy vegetables, quinoa, sweet potatoes, pumpkin, sunflower and sesame seeds.


Alcohol, smoking, recreational drugs and stress can negatively affect fertility in men. When trying to conceive, it would be useful to look into your lifestyle and adopt some healthy habits:

– Keeping caffeine to a maximum of two cups a day. Don’t forget caffeine is also found in chocolate, green or black tea and some soft drinks. 

– Limiting alcohol to 3 units a week. If you are undertaking fertility treatment, abstain from alcohol for 6 weeks before the treatment.

– Getting enough good quality sleep and reducing stress – read more about stress and fertility here.

– Stop taking recreational drugs and quit smoking, read more about smoking and fertility here.
