Conventional treatments of male infertility in the age of evidence-based andrology.

The field of reproductive medicine is characterized by the rapid development of assisted fertilization. Today, fertilization can be achieved by cytoplasmic microinjection of single spermatozoa or spermatids into oocyte cytoplasm. In view of these new reproductive techniques, conventional diagnosis and treatment of male infertility seem to be rather outdated and limited. However, the final goal of reproductive medicine should be to improve reproductive function in order to provide each couple with the chance of conceiving offspring naturally. In this paper we analyse the effectiveness of current conventional treatments of male infertility in the light of high-quality studies and emphasize that future therapies must be evaluated in properly conducted studies.
