Objective:To investigate the correlation between TNF-α and IL-6 levels in cervical mucous during follicular development and ovulation stimulation in different protocols.Methods:36 infertile women were set up as experimental groups,divided into CC,HMG,IVF-ET group,each group consisted of 12 infertile women and 15 women with normal menstrual cycles were choiced as control group.Cervical mucous during follicular phase,luteal phase and ovulation phase were collected.TNF-a,IL-6 levels in cervical mucous were measured by radioimmunology assay(RIA).Follicular development were monitored by transvaginal ultrasonagraphy.Results:(1)TNF-α levels in cervical mucous of experimental groups and control group were periodically various among the reproductive cycle.It increased during follicular phase,reached to peak during ovulation phase,and decreased during luteal phase(P<0.05).IL-6 levels had no obvious periodical changes.(2)Compared with CC and control group,levels of TNF-α,IL-6 in HMG and IVF-ET group were significantly higher(P<0.05).(3)Levels of TNF-α and IL-6 in cervical mucous were positively correlated with the dominant follicle diameter(r=0.261,r=0.192 respectively,P<0.05).(4)TNF-α and IL-6 showed positive correlation in the reproductive cycle(r=0.782,P<0.05).Conclusions:(1)TNF-α level shows a cyclic change in the reproductive cycle and peaks during ovulation,whereas IL-6 level does not.(2)TNF-α and IL-6 may play a certain role in the process of follicular development and ovulation.(3)The levels of TNF-α and IL-6 are up-regulated by gonadotrophic hormone.(4)TNF-α and IL-6 may have coordination properties and participate in the same biological effects.
