Cytokines are cellular messengers which play a key role in many biological conditions such as immune defence and reproduction. During recent years analysis of seminal cytokines has become of increasing interest in various pathologies. To evaluate the current role of seminal cytokines we performed a systematic literature search within the framework of our focus group "Male Infertility during Infection and Inflammation - MIBIE". Out of 581 manuscripts we identified 124 original articles which investigated a total of 31 different cytokines. These studies can be categorized according to the following three topics: infertility, infections and chronic prostatitis. The current analysis demonstrates that seminal cytokine profiles are not associated with either semen quality or fertility; however, cytokines might be beneficial for diagnosis and monitoring therapy in patients with urogenital infections/inflammation. Further studies are needed to clarify if a single cytokine or a combination of different cytokines is necessary to evaluate different pathologies.

Adverse immune reactions develop in up to 30% of patients treated with gold compounds. However, sensitization to gold(I) drugs is rarely demonstrated by in vivo or in vitro testing. Recent data from a mouse model provides evidence that gold(I) is oxidized to gold(III) before T cells are sensitized. To study the diagnostic value of skin tests, patch testing with various gold compounds / including gold(I) and gold(III) / was performed in 50 patients with rheumatoid arthritis treated with gold(I) drugs. Positive patch test reactions to either gold(I) or gold(III) compounds were not detected. In contrast, the lymphocyte transformation test (LTT) revealed a gold(III)/induced response in one of the 7 patients being tested. We conclude that patch testing fails to indicate T cell sensitization to gold(I) drugs in rheumatoid arthritis patients. The in vitro response to gold(III) obtained by LTT supports the hypothesis that biooxidation of gold(I) compounds may play a crucial role for sensitization.

This contribution discusses new aspects in andrology focusing on infertility, erectile dysfunction (ED), and hypogonadism. Topics such as prostatitis and detection of Chlamydia, idiopathic infertility and PDE5 inhibitors, and ED after GreenLight laser treatment are addressed.
