Cigarette Smoking Affects Uterine Receptivity Markers
Cigarette smoking decreased expression of endometrial receptivity markers CXCL12 and FGF2 in vitro, in mice, and in human samples.

The study evaluated how cigarette smoking affects human uterine endometrial physiology by examining the cytokines CXCL12 and FGF2, and related them to uterine receptivity, using both in vitro experiments (human endometrial stromal cell lines and primary cells treated with cigarette smoking extract) and in vivo mouse experiments (uterine tissue after 8 weeks of cigarette smoke exposure). In parallel, human endometrial samples from nonsmokers and smokers were analyzed by real-time RT-PCR and, in mice, by immunohistochemistry for CXCL12 and FGF2 protein. Both CXCL12 and FGF2 mRNA and protein levels were significantly decreased in smoking-exposed cells and mice, and similarly lower in endometrium from women who smoke. The paper’s main caveat is that its findings focus on specific receptivity-associated markers rather than directly measuring fertility outcomes. This paper is centrally about endometriosis — it discusses smoking-associated, reduced prevalence of endometriosis and links decreased CXCL12 and FGF2 expression to mechanisms implicated in endometriosis.
