It is estimated that it affects 10% of women of reproductive age. Its pathogenesis covers a wide range of abnormalities, including adhesion, proliferation, and cell signaling disturbances. It is associated with a significant deterioration in quality of life as a result of chronic pelvic pain and may also lead to infertility. One of the most serious complications of endometriosis is an ectopic pregnancy (EP). Currently, the exact mechanism explaining this phenomenon is unknown; therefore, there are no effective methods of prevention. It is assumed that the pathogenesis of EP is influenced by abnormalities in the contraction of the fallopian tube muscles, the mobility of the cilia, and in the fallopian microenvironment. Endometriosis can disrupt function on all three levels and thus contribute to the implantation of the embryo beyond the physiological site. This review takes into account aspects of the molecular mechanisms involved in the pathophysiology of endometriosis and EP, with particular emphasis on the similarities between them.<\/jats:p>","DOI":"10.3390\/ijms23073490","type":"journal-article","created":{"date-parts":[[2022,3,23]],"date-time":"2022-03-23T12:20:25Z","timestamp":1648038025000},"page":"3490","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Molecular Mechanisms Underlying the Association between Endometriosis and Ectopic Pregnancy"],"prefix":"10.3390","volume":"23","author":[{"given":"Julia","family":"Za\u0142\u0119cka","sequence":"first","affiliation":[{"name":"1st Department of Obstetrics and Gynecology, Medical University of Warsaw, Starynkiewicza 1\/3, 02-015 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarzyna","family":"Pankiewicz","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Institute of Mother and Child in Warsaw, Kasprzaka 17a, 01-211 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3647-3550","authenticated-orcid":false,"given":"Tadeusz","family":"Issat","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Institute of Mother and Child in Warsaw, Kasprzaka 17a, 01-211 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piotr","family":"Lauda\u0144ski","sequence":"additional","affiliation":[{"name":"1st Department of Obstetrics and Gynecology, Medical University of Warsaw, Starynkiewicza 1\/3, 02-015 Warsaw, Poland"},{"name":"OVIklinika Infertility Center, Po\u0142czy\u0144ska 31, 01-377 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"261","DOI":"10.1038\/nrendo.2013.255","article-title":"Endometriosis: Pathogenesis and Treatment","volume":"10","author":"Vercellini","year":"2014","journal-title":"Nat.
