Cigarette smoking is associated with lower fecundity rate, adverse reproductive outcomes and higher risk of IVF failure. Over the last decades, prevalence of smoking among women of reproductive age has increased. The aim of this work was first to focus on the knowledge of the effects of cigarette smoking on reproductive stages and particularly on implantation process and early placentation. Human clinical and experimental studies were analysed in order to find hypothesis and explanations for the effects observed. Then, our second aim was to analyse which factors could influence smoke effects. We observed that smoke compounds induce impairment of endometrial maturation, disturb angiogenesis and trophoblastic invasion. Cigarette compounds also impair uterine and endometrial vascularisation and myometrial relaxation. These effects lead to implantation failure in IVF and higher risk of miscarriage. Many factors influence the effects of cigarette smoke, as smoke behaviour, dose and duration of exposition. Sidestream is also damaging on reproductive function. Prenatal exposure leads to irreversible and deleterious effects on ovarian reserve. These observations need to be confirmed in order to improve health care in women of reproductive age.
