Heterotopic cervical pregnancy is an even rare form of EP, in which at least two embryos are simultaneously implanted in different sites and only one in the uterine cavity. Although many treatment approaches are available, the ideal management remains unclear. Here, we describe two cases of CP caused by assisted reproductive technologies (ART). One case underwent fertilization with intracytoplasmic sperm injection (ICSI) for male factor infertility, and the other was frozen\u2013thawed embryo transfer (FET) following conventional in vitro fertilization (IVF). Both cases were successfully treated with ultrasound\u2010guided cervical pregnancy aspiration, and intrauterine pregnancies were effectively protected. To the best of our knowledge, these two were rare case reports use aspiration without additional methods and intrauterine pregnancy achieved live birth.<\/jats:p>","DOI":"10.1111\/jog.15193","type":"journal-article","created":{"date-parts":[[2022,2,22]],"date-time":"2022-02-22T06:02:55Z","timestamp":1645509775000},"page":"1271-1278","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Heterotopic
