Abstract: Hydrosalpinx with a high incidence in women of child-bearing age not only damages their fertility，but also has an obvious adverse effect on the outcomes of IVF-ET. It is always a problem how to handle properly hydrosalpinx before IVF-ET，even there is not a international guideline for standard treatment. There are several classical methods including transvaginal hydrosalpinx aspiration，salpingectomy，proximal tubal ligation，distal salpingostomy and fallopian tube proximal end occlusion. Based on recent publications on the pretreatment protocols of hydrosalpinx before IVF-ET，the advantages and disadvantages of those protocols were reviewed in this paper，while the hysteroscopic fallopian tube proximal end occlusion was especially evaluated，including its feasibility and safety. This therapy has recently been proved to be efficient. It is inconclusive which of the current pretreatment protocols for hydrosalpinx to be better. Hysteroscopic fallopian tube proximal end occlusion，as a new method with advantages of wider indications，effeciency，mild invasion，simple and economic method，is worthy of being recommended in clinical application.
