Those couples who can only have children with medical help should always have in mind that besides the necessary examinations and possibly medication, they can contribute a lot to support development and progression of a normal pregnancy.

Nutrition The metabolism has a great influence on the hormon balance (overweight/underweight). A nutrition rich in protein and vitamins is recommended, whereas ingesting too many carbs and fats should be avoided.

High protein foods are: lean meat, fish, cheese, eggs and curd cheese. Fruits and vegetables are high in vitamins.
Carbs (bread, pastries, sugar, flour, potatoes, etc.) and fats (lard, oil, butter) should be eaten only in small quantities. This applies particularly for overweight women.

Alcohol (regardless if it is wine, beer, cognac, etc) should be consumed in small quantities only. In case of a recent or acute liver disease, alcohol should be avoided completely.

Overdosing forbidden substances could produce: an underweight baby, spontaneous miscarriages, genetic disorders and also a higher risk of cancer in children. Studies showed that the lung cancer rate in men, whose fathers were exposed to the same vapours with chromium compounds as men doing welding, increased. Therefore men should avoid alcohol and nicotine, and should stay away from chemicals and radiation for at least 90 days. Thus their sperm will have enough time for recreation.
