Overview
The EFFORT study compares the impact on fertility of operation or fertility treatment (IVF, in vitro fertilization) in a multicenter randomized controlled trial. The study population consists of women with colorectal deep infiltrating endometriosis and a pregnancy intention. These women will be randomized to either of the two treatment groups: Group A = Operation or Group B = fertility treatment (IVF). Group A will be further divided postoperatively into spontaneous conception or IVF depending on the Endometriosis Fertility Index score.
