However, the efficacy of aspirin to reduce the rate of preeclampsia for all pregnancies resulting from in vitro fertilisation remains uncertain, although in vitro fertilisation conception is a well-known risk factor for preeclampsia. Therefore, the purpose of this scoping review is to provide a comprehensive overview of the current literature regarding the use of low-dose aspirin to prevent hypertensive disorders of pregnancy after in vitro fertilisation.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Inclusion criteria<\/jats:title>\n<jats:p>This review will identify all peer-reviewed published articles including pregnant women who underwent embryo transfer after in vitro fertilisation and were prescribed low-dose aspirin to reduce the risk of hypertensive disorders of pregnancy.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>We have devised a comprehensive search strategy to systematically identify pertinent studies published from January 2000 until May 2024, within the Medline (PubMed interface), Embase and Scopus databases.
