If you've been trying to start a family without success, making some simple lifestyle changes may increase your chance of conception and help to ensure a healthy pregnancy. However, there are some factors, such as age, ovulation problems, sperm disorders and damaged fallopian tubes, that you can't change.
Changes you can make
Eat well: if you're a woman, a nutritious, balanced diet will help improve your general health and wellbeing, and ensure your body is able to nourish a baby. If you're a man, healthy eating is also important for sperm production.
Choose a varied diet containing fresh fruit and vegetables, bread, potatoes, rice and other cereals (wholegrain, where possible), low-fat milk and dairy products, lean meat, fish and other sources of protein.
Watch your weight: being overweight or very underweight can disrupt your periods and hinder conception. A woman with a body mass index (BMI) of more than 29 or less than 19 may find it more difficult to conceive.
