title: Does hydrosalpinx reduce the pregnancy rate after in vitro fertilization?
abstract: OBJECTIVE
  To determine the effect of hydrosalpinges on the pregnancy rate in an IVF program.
  
  
  METHODS
  Multicentric retrospective analysis of clinical and laboratory data.
  
  
  METHODS
  Two assisted reproductive technology centers in university hospitals.
  
  
  METHODS
  Four hundred forty-three women, under 38 years of age, with pure tubal infertility. The patients were classified into the following five groups: bilateral hydrosalpinges (n = 37), unilateral hydrosalpinx (n = 54), bilateral tubal occlusion (n = 207), unilateral tubal occlusion (n = 55), and severe tubal disease without complete occlusion (n = 90).
  
  
  METHODS
  Pregnancy and implantation rates.
  
  
  RESULTS
  The pregnancy and the implantation rates per transfer (12.3% and 5.4%) obtained by women with bilateral hydrosalpinges are significantly lower than the rates (means = 23.1% and 12%) for all other tubal infertility groups.
  
  
  CONCLUSIONS
  Bilateral hydrosalpinges have a deleterious effect on the outcome of IVF program.
