چکیده

normal 0 false false false en-us x-none ar-sa background: cigarette smoke contains many oxidants and may alter the human reproduction by inducing oxidative stress (os) in both active and passive smokers. this study was designed to evaluate the effect of environmental tobacco smoke (ets) exposure on oxidative stress in the follicular follicle and the assisted reproduction outcomes. materials and methods: an observational prospective study was carried out on 236 infertile women, who underwent assisted reproduction cycles. the ets exposure was assessed using self-reported ets exposure and the cotinine level in follicular fluid. to evaluate the os in follicular fluid (ff) malon-di-aldehyde (mda) and total antioxidant capacity (tac) were measured. the number of retrieved oocytes, rate of metaphase ii stage oocytes, fertilization rate, good cleavage rate, and no-fragmented embryo rate were considered as the assisted reproduction outcomes. the results were adjusted for age, body mass index, duration, and etiology of infertility; p -values less than 0.05 were considered significant. results: the mda and tac levels in ff were not related to the self-report number of the weekly ets exposure and cotinine levels in ff. also, the number of retrieved oocytes, mii stage oocytes, fertilization rate, good cleavage rate, and no-fragmented embryo rate were not related to the cotinine level and weekly ets exposure. however, in women whose cotinine levels in ff were lower and equal/above 3.5 ng/ml, the number of retrieved oocytes was higher (12.63 ± 0 .71 vs. 9.28 ± 1.11, p = 0.01). the relationship between the mda level and cleavage rate (beta = −18.5, confidence interval-34.9 and-2.1, p < 0.05) was negatively significant and the relationship between the mii stage rate with tac (beta = 0.02, confidence interval 0.01 and 0.04, p < 0.05) was positively significant. conclusion: the ets exposure may alter the assisted reproduction success by influencing the number of available oocytes. although, the os in a follicular environment affect the ability of oocytes to reach the specific cleavage stages at appropriate time intervals, it does not mediate poor-assisted reproduction outcomes due to ets exposure.
