TNF-α and IL-6 affect human sperm function by elevating nitric oxide production

Abstract: Many studies have reported the effects of cytokines on human sperm function, even though their role and the mechanisms involved remain unclear. The effects of increasing concentrations of the cytokines TNF-alpha and IL-6 on human sperm motility and viability were assessed, and the possible mechanisms involved were investigated. TNF-alpha and IL-6 significantly reduced progressive motility at higher concentrations in a dose- and time-dependent manner. No differences were observed in cell viability. Both cytokin… Show more

“…These observations are supported by the findings of Allam et al [104], who detected a correlation between seminal TNF-a level and apoptotic sperm in ejaculates from men with chronic urogenital tract inflammations. The proapoptotic effect of TNF-a on mature sperm cells can be mediated through ROS and nitric oxide production [152][153][154]. Little is known about the proapoptotic properties of IL-6, a proinflammatory cytokine produced in large amounts during semen infection.…”

“…Furthermore, a number of various adipokines at higher concentrations from excess white adipose tissue have been linked to male infertility. It was shown that two adipocyte-released adipokines (tumor necrosis factor-a and interleukin-6) signifi cantly reduced human sperm progressive motility in a dose-and timedependent manner, by promoting the elevation of nitric oxide production to pathological levels 36 . Moreover, increased release of adipokines results in infl ammation and can have a toxic eff ect on spermatozoa through the release of excess reactive oxygen species and reactive nitrogen species 37 .…”

“…Была показана различная экспрессия TNFα в за-висимости от фазы менструального цикла: ми-нимальная экспрессия была отмечена в раннюю пролиферативную фазу, максимальная -в позд-нюю пролиферативную фазу [41]. Повышенная продукция TNFα при эндометриозе связана с ОБЗОРЫ ТО М L X I I В Ы П УС К 6 / 2 0 1 3 бесплодием, оказывая влияние на подвижность, функции и развитие сперматозоидов [41,53,69].…”

“…У женщин IL-6 слабо эскпрессируется в пролиферативную фазу менструального цикла, но на достаточно высоком уровне экспрессирует-ся в среднюю секреторную фазу цикла, преиму-щественно в железистых эпителиальных клетках эндометрия [30]. Следует заметить, что не только низкий, но и высокий уровень IL-6 может оказы-вать влияние на фертильность с связи с эмбрио-токсическими и сперматотоксическими свойства-ми данного цитокина [36,53,59]. При эндометри-озе в ПЖ наблюдается повышенный уровень IL-6 [2].…”
