Does surgery for colorectal endometriosis prior to IVF±ICSI have an impact on cumulative live birth rates?

ABSTRACT

RESEARCH QUESTION Does colorectal endometriosis surgery prior to IVF ± intracytoplasmic sperm injection (ICSI) impact cumulative live birth rates? DESIGN: This retrospective, monocentric study (Lille University Hospital) was conducted between 1 January 2007 and 31 December 2018. Two groups of patients from the JFIV database were included a group undergoing IVF±ICSI alone (120 patients, 215 oocyte retrievals), and a group undergoing surgery and then IVF±ICSI (69 patients, 109 oocyte retrievals). The mode of management was decided after a multidisciplinary team meeting. Different criteria such as age (cut-off 35 years), anti-Müllerian hormone concentration (cut off 2 ng/ml), imaging results and the patient's symptomatology were considered the most symptomatic patients underwent surgery prior to IVF±ICSI. The cumulative clinical pregnancy and live birth rates obtained after four IVF attempts were estimated and compared between the two groups using competing risk survival methods. RESULTS: The cumulative live birth rates after four IVF attempts in the two groups were not statistically significantly different (50.8% in the IVF±ICSI group versus 52.2% in the surgery followed by IVF±ICSI group, P = 0.43). The results for the cumulative clinical pregnancy rates were the same (56.7% in the IVF±ICSI group versus 58% in the surgery followed by IVF±ICSI group, P = 0.47). CONCLUSION: The study shows that cumulative live birth and pregnancy rates were similar in infertile patients with colorectal endometriosis who underwent IVF±ICSI either with or without prior colorectal endometriosis surgery.
