Application of transabdominal wall press and vaginal B-ultrasound probe to adjust ovarian position in oocyte retrieval / 中国医师杂志

ABSTRACT

Objective:The aim of this study was to investigate the efficacy and safety of rtansabdominal wall press to adjust ovarian position in patients with difficulty in oocyte retrieval.Methods:A retrospective case-control study was conducted to collect 177 patients with difficulty in oocyte retrieval from January 2020 to December 2021 in the Reproductive Medical Center of Peking University Shenzhen Hospital. Among the 177 patients with difficulty in oocyte retrieval, 76 patients used transabdominal wall press to adjust the position of the ovary (pushing group), and the other 101 patients were treated with routine oocyte retrieval (control group). The oocyte retrieval rate, the number of oocyte and mature oocyte, the number of transferable embryos and high-quality embryos were compared between the two groups, and the incidence of complications was recorded.Results:There was no significant difference between the two groups in the ovarian stimulation program, the dosage of ovulation promoting drugs and the number of follicles ≥14 mm on human chorionic gonadotropin (HCG) day (all P>0.05). The days of promoting ovulation in the pushing group were longer than those in the control group, and the level of estradiol on HCG day was significantly higher than that in the control group (all P<0.05). The rate of oocyte retrieval, the number of oocytes retrieved, the number of transferable embryos and high-quality embryos in the pushing group were significantly higher than those in the control group (all P<0.05). The incidence of complications during oocyte retrieval in the pushing group was significantly lower than that in the control group ( P=0.003). Conclusions:Transabdominal wall press to adjust ovarian position can improve oocyte retrieval rate and reduce the incidence of complications in patients with difficulty in oocyte retrieval.
