Unfulfilled desire for children

For most couples the desire for having a child is fulfilled naturally. However, about 20 % of all couples remain involuntarily childless. In 45 % of cases the underlying cause can be assigned to female reproductive problems, in 40 % to male factor problems. In 10 % of all cases a combination of male and female factor problems are responsible for the infertility. In 5 % of infertility cases the reasons cannot be determined and therefore remain unexplained (this is referred to as idiopathic sterility). Couples undergoing fertility treatment should live in a healthy partnership. With respect to the dignity of the longed-for child, we strive to make your dream come true with the help of recognized medical procedures.


An oocyte usually matures in a follicle in one of the ovaries within two weeks of menstrual bleeding. Ovulation is induced by complex hormonal regulatory mechanisms. The mature ovum that is now capable of being fertilized is caught by the fimbria of the fallopian tube and starts travelling down the fallopian tube towards the uterine cavity. The spermatozoa deposited in the vagina at the time of ejaculation travel through the uterus into the fallopian tube where only one sperm cell fertilizes the ovum. The fertilized ovum, now referred to as the embryo, already starts dividing (cleavage) on its way through the fallopian tube towards the uterus. On average 4-5 days after ovulation the embryo reaches the uterine cavity where it starts implanting into the endometrium 5-6 days after fertilization has occurred.


Any couple who intends to achieve parenthood with the help of assisted reproductive technologies should bear in mind that, apart from the medical exams and medication that might be prescribed, you can contribute a lot to a successful pregnancy outcome.


Metabolism has an essential impact on a healthy hormonal balance (overweight, underweight). It is recommended to reduce the intake of carbohydrates and fats and instead eat a well-balanced diet rich in vitamins and proteins. Rich sources of animal protein are dairy products (especially low fat curd), meat, fish and eggs. Germs or seeds, beans (e.g. soya), whole grain, legumes such as peas and lentils and vegetables (particularly algae and Shiitake mushrooms) are valuable vegetable sources of protein.
Fruit and vegetables are rich in vitamins. Carbohydrates (e.g. bread, pastries, sugar, flour, potatoes etc.) as well as fats (such as oil and butter) should be consumed in moderate quantities only. This is especially important if you have a higher-than-normal bodyweight. Alcohol, no matter whether it is beer, wine, must, cognac etc. should be consumed in small quantities only. If you suffer or have suffered from a liver condition you should completely abstain from alcohol.


It is well known that nicotine may compromise both male and female fertility.
Moreover, toxic substances, such as nicotine have a negative impact on the developing organism of the unborn child. Children of smoking mothers are often found to be smaller upon delivery and are more prone to illness.

The woman can make a major contribution to give birth to a healthy child by giving up smoking 2 - 3 months prior to fertility treatment. Several studies have shown that, even if only one of the partners smokes, the chances of conceiving and carrying a pregnancy to full term are considerably reduced!


The possible consequences of environmental toxins (e.g. fumes or radiation at the workplace, plastic materials and many more) can be an underweight baby upon delivery, spontaneous miscarriages, genetic disorders and even a higher risk of cancer in children. Therefore couples should stay away from chemicals and radiation (e.g. at your workplace) for at least 90 days prior to conception. This provides sufficient time for their sperm (spermatogenesis) and ova (oogenesis) to recreate. You should also do your best to avoid environmental toxics during pregnancy.


The SPINA BIFIDA (incomplete closing of the embryonic neural tube) is considered to be the most common congenital disorder. In the total population, 4-5 children per 1000 live births are affected. Thus, it is recommended to take folic acid dietary supplements with at least 400 µg per day (e.g. Fertilovit F®). After consulting your doctor, start taking the recommended dosage of folic acid at least 4 weeks prior to conception and continue during early pregnancy. Thus, the occurrence of this specific congenital malformation can be reduced by 50-70%. Other congenital disorders such as facial clefts or pathological changes in the cardio-vascular system, the urinary system or the limbs can often be prevented by the intake of folic acid.
