[Infectious agents and treatment of infertility with IVF and ET]

An infectious agent is a confirmed etiological factor of female tubal sterility. In conjunction with the recorded decline of fertility of the male population the participation of infection in this trend can be taken into consideration. In the submitted paper the authors are concerned with the detection of an infectious agent in spermatozoa in the sterile population and its role when using assisted reproduction techniques (ART). From the results ensues that cultivation examinations of spermatozoa before a programme of in vitro fertilization and embryo transfer (IVF + ET) has its place in the screening of the treated couple. Detection of virulent types of microorganisms has a negative effect on results of IVF + ET. Groups of men with this finding should be treated with antibiotics with regard to sensitivity and at the same time cultivation examinations of their partners should be made an necessary treatment and provided.
