The management of hydrosalpinges before in-vitro fertilization and embryo transfer.

Several recent studies have shown that the presence of hydrosalpinges adversely affects clinical pregnancy rates achieved with in-vitro fertilization and embryo transfer. Hydrosalpinx fluid may be toxic to the endometrium or embryo, or may mechanically interfere with implantation. Some authors recommend surgical correction of hydrosalpinges before in-vitro fertilization and have shown promising results with this approach. Proper patient selection for this therapy still needs to be defined.
