Infertility in couples is defined after 12 months of regular unprotected intercourse. According to research, 15-18% of population worldwide currently suffers from infertility, which corresponds to ca. 80 million couples. In Poland, every fifth couple is affected, meaning that ca. 1.5 million couples are struggling to conceive. For 30-50% of them, medically assisted reproduction offers the only chance of parenthood.

Infertility affects both partners and not exclusively the woman or the man. In ca. 40% of cases, it is caused by a female factor, in 35% of cases a male factor is responsible. In many couples a female and male factor often coexist. Unfortunately, ca. 20% of infertile couples are affected by unexplained infertility.

Ovulation problems as well as congenital and acquired anatomical abnormalities are among the most frequent causes of infertility in women. The most common cause in men are poor sperm parameters, which still have many unexplored roots.
