Double primary gynecological cancers cause inevitable damage to female reproductive function, and the preservation of fertility in such patients remains a challenging issue as relatively few cases have been reported. This case report provides management options for dual primary ovarian and endometrial cancers, including the choice of ovulation induction protocols, considerations during pregnancy and parturition, with the aim of providing assistance to clinicians.  \nCase presentation We report a case of a 39-year-old woman with primary infertility and a medical history of rightsided ovarian mucinous borderline tumor with intraepithelial carcinoma, left-sided ovarian mucinous cystadenoma and endometrial cancer, who successfully conceived with in vitro fertilization-embryo transfer (IVF-ET) after three different ovulation induction protocols. During her pregnancy, she was complicated by central placenta praevia with placental implantation and eventually delivered a healthy female infant by caesarean section at 33 gestational weeks. Conclusions For patients with double primary gynecological cancers who have an intense desire for fertility, the most appropriate oncological treatment should be applied according to the patient’s individual situation, and fertility preservation should be performed promptly. Ovulation induction protocol should be individualized and deliberate, with the aim of ensuring that the patient’s hormone levels do not precipitate a recurrence of the primary disease during induction of ovulation and maximizing fertility outcomes. In addition, the risk of postpartum hemorrhage due to placental factors cannot be neglected in such patients.  \nKeywords Endometrial cancer, Intraepithelial carcinoma, Placenta previa, Placenta accreta spectrum, In vitro fertilization-embryo transfer (IVF-ET), Case report  \n*Correspondence: Yu Liang [liangyu1981830@163.com](liangyu1981830@163.com)[ ](liangyu1981830@163.com)Xiaokui Yang [yangxiaokui@ccmu.edu.cn](yangxiaokui@ccmu.edu.cn)  \n1Department of Human Reproductive Medicine, Beijing Obstetrics and Gynecology Hospital, Capital Medical University, Beijing, China 2Beijing Maternal and Child Health Care Hospital, Beijing, China  \n© The Author(s) 2023.
