“…Many other cytokines (including GM‐CSF, HGF, IFN‐α, IFN‐γ, IL‐2, IL‐4, IL‐7, IL‐10, IL‐12, IL‐18, MCP‐1, MIP‐1β, and platelet‐derived growth factor (PDGF)) have been identified in follicular fluid (Orvieto et al, ; Bili et al, ; Artini et al, ; Kawano et al, ; Hammadeh et al, ; Dahm‐Kahler et al, ; Vujisic et al, ; Ostanin et al, ; Cerkiene et al, ; Ledee et al, ; Kilic et al, ; Boomsma et al, ; Pelzer et al, ; Yang et al, ; Lamaita et al, ; Sarapik et al, ). One recent study showed that IL‐8, IL‐18, and MIP‐1β levels positively correlated with pregnancy outcome in IVF cycles, while total IL‐12 levels reflected oocyte fertilisation and subsequent embryo development (Sarapik et al, ).…”
