Discussion
Our study demonstrates that in subfertile women with confirmed bilateral severe hydrosalpinges, salpingectomy compared to neosalpingostomy resulted in higher cumulative livebirth rate, shorter time to first live birth and lower risk of EP, when also the result of additional IVF in both groups are taken into account. There were no natural conceptions after salpingectomy, while neosalpingostomy resulted in a 20.7% (12/58) cumulative natural conception rates leading to live birth without any additional surgical interventions. This may be relevant for women in the higher age group, since IVF is not always an option. In the age group between 34 and 45 years we could not find statistically significant differences between two groups. However, our sample size for this subgroup may not have been sufficient. Future studies are needed to confirm this.
