Fertilitydisorders are one of the most serious and at the same time very common health problems of young couples in Poland and worldwide. It affects approximately 10-15% of people of reproductive age. The latest medical data suggest that the number of couples with this problem oscillates around 150 million people! In Poland, there are no statistics on this subject. We can therefore only use estimates. They speak of the number of approximately one million people who, despite their efforts, are unable to conceive. These figures are truly frightening, so it is worth looking into the causes of fertility disorders.
