Mínguez-Alarcón L, et al. - Researchers aimed at summarizing the epidemiologic literature on intakes of caffeine and alcohol, smoking, and reproductive outcomes among women undergoing assisted reproductive technologies (ART) in order to ascertain the effects of some of these exposures on ART outcomes. They gained a little evidence indicating a detrimental effect of moderate caffeine intake on ART outcomes. ART outcomes may be adversely affected by the current consumption of alcohol, but at present the evidence is limited. For women who currently smoke cigarettes, they note consistently poorer ART outcomes, including reduced live birth rates. However, studies quantifying the benefits of smoking cessation are lacking.
