Seven hundred sixty-two patients were identified retrospectively. Thirty-three patients were excluded, thirty did not meet the inclusion criteria and three underwent an incomplete endometrium ablation. The remaining 729 patients were contacted, resulting in a response-rate of 61% (N = 446). A total amount of 446 patients was available for analysis (1).

The mean number of parity was 2.2 (SD ± 1.0, missing values 0). Sixty-one (13.7%) of the patients underwent a caesarean section. The mean number of previous caesarean section was 0.2 (SD ± 0.6, missing values 0)
