Hydrosalpinx reduces in-vitro fertilization/embryo transfer pregnancy rates

A retrospective study was designed to examine whether the presenceof a hydrosalpinx influenced pregnancy outcome following in-vitrofertilization (IVF) treatment In stimulated cycles. A totalof 254 women with tubal lesions were included. Patients withone or two hydrosalpinges were compared with patients havingother tubal lesions and pregnancy outcome was analysed. Bothpregnancy and delivery rates were significantly higher in thepatient group without a hydrosalplnx. The results after frozenembryo transfer showed the same tendency. These findings stronglyindicate that a permanent hydrosalpinx has a negative influenceon implantation, as well as on pregnancy, and suggest that amore active approach against large hydrosalpinges should beundertaken before I.VF treatment, in order to improve the pregnancyrates.
