Infertility and subfertility affect a significant part of the population. Among various definitions of this pathology, the most common one is provided by the World Health Organisation; it says that infertility is 'a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourses'. The global prevalence of infertility is about 50-70 million couples. Since the process of human reproduction involves a large number of factors, a broad spectrum of infertility tests might be applied. Some of the tests focus directly on the pregnancy, some are only partially effective, whereas others should not be recommended for infertile couples. The aim of this review is to present a critical evaluation of the infertility diagnostic process and to discuss the recommendations for its most effective treatment.
