Advanced maternal age, obesity and cigarette smoking are associated with decreased fertility, adverse Assisted Reproductive Technologies (ART) outcomes and fetal and neonatal complications. IVF failures increase dramatically in women aged between 42-43 years. Advanced paternal age is associated with fetal and neonatal adverse outcomes. However, it remains uncertain that advanced paternal age could impair IVF results. Obesity (Body mass index more than 30 kg/m(2)) is associated with lower fecundity, pregnancy complications and adverse ART results. The rate of complications is increasing with higher BMI. Cigarette smoking is associated with longer time to conceive and decreased IVF results. In case of infertility associated with obesity or cigarette smoking, physicians have to inform their patient about the benefits of smoking cessation and weight loss. However, maternal age had to be considered as the main prognosis factor before delaying ART because of dietary or smoking cessation program.
