Reasons for infertility

One in six couples worldwide are affected by infertility. According to statistics, about  40% of fertility are caused by a female factor, another 40% by male. The remaining cases of infertility are due to mixed or unknown causes.

According to the World Health Organisation (WHO), infertility is diagnosed when a pregnancy could not be achieved naturally after one year. In this case, you should consult a specialist as soon as possible to determine the cause of infertility.

At IVF-Spain Madrid we know how difficult it is to make the first step. Especially when it is such a sensitive and private issue.

For this reason, we respond to our patients’ needs and travel around the German-speaking countries (cities such as Berlin, Cologne, Frankfurt or Zurich) with free consultations. We also organise regular webinars to explain the basic points of Spanish fertility medicine.

Reasons for infertility

The age. Nowadays people decide to have children much later as their parents did. For this reason, the term “ovarian reserve” becomes more important.

The ovarian reserve is the ability of the ovaries to produce eggs.  It remains stable until around 35 years of age, after which it decreases sharply. As the egg cell reserve decreases, a woman’s chances of pregnancy also decrease significantly.

Endometriosis is the growth of endometrium-like cells outside the uterine cavity.  Although the disease is benign, it has many unpleasant consequences such as pain and in 30-50% of cases the infertility. This is because the female reproductive system is affected by this endometrium-like tissue: Cysts and reduced egg quality are possible consequences. Another consequence is the formation of adhesions or fluids in the fallopian tubes, which prevents that the eggs can be fertilized naturally.

Anovulation, i.e. the failure to ovulate, is the reason for infertility in about 20% to 25% of cases. The reason for anovulation is certain abnormalities in the hormones produced by the brain and ovaries. Unfortunately, women with polycystic ovarian syndrome often also suffer from anovulation and consequently infertility.

Sperm quality. In recent years, the quality of sperm in the male population worldwide has decreased significantly. The reasons for this are many and varied: from environmental pollution to unhealthy lifestyles.  The consequences are low concentration and sperm motility or morphology and other anomalies. All these factors cause male infertility.

The importance of a correct diagnosis

In order to achieve pregnancy, many important factors have to be identified and taken into account during the treatment. If one of these pieces of the puzzle is missing, the result can be a failed treatment.

Choosing the right fertility clinic is therefore of fundamental importance.  Both the experience of the medical team and the technical equipment of the clinic are essential for a correct diagnosis. At IVF-Spain Madrid the patient journey is highly personalised and precise.

Everything is designed to analyse the cause of infertility and offer a solution to it. At every stage of the treatment we provide our patients with the best technologies and know-how in reproductive medicine.  Our aim is to fulfil our patients’ desire to have children in the shortest possible time and with the least possible physical and emotional stress.
