The following tips can be passed onto couples trying to conceive to help give them the best possible chance of success:

• Women should take 400mcg of folic acid daily while trying to conceive and until week 12 of pregnancy, as it helps prevent neural tube defects such as spina bifida. Green, leafy vegetables, citrus fruits, beans and wholegrains are good dietary sources
• Don’t smoke
• Drink sensibly – within the guidelines for men and not at all for women
• Eat a healthy diet rich in fruit and vegetables, wholegrains, lean protein and dairy
• Take regular exercise
• Men and women should maintain a BMI of between 18.5 and 24.9
• Have unprotected sex every two to three days
• Keep testicles cool, avoiding tight underwear and hot showers
• Women should be up to date with all health checks, including cervical smears, STI tests, and vaccinations, particularly against rubella (German measles) and chickenpox
• Be aware that not all prescription or OTC medication is suitable during pregnancy and alternatives may be required.

If a woman suffers from an existing medical condition such as diabetes, epilepsy, thyroid disease or asthma, a GP may need to ensure that the condition is controlled before pregnancy.
