Patients: Three hundred seventy patients undergoing 489 stimulation cycles.
The patients were classified in to the following four groups: hydrosalpinx (n=44 cycle), tubal disease other than hydrosalpinx (n=153 cycle), male factor (n=102 cycle), and all the other causes (n=146 cycle).
Main out come measures: Numbers of oocytes retrieved and fertilized, the number of embryos transferred and implanted, and resulting pregnancy rates.
Results: The patients with hydrosalpinx had greater number of oocytes retrieved per cycle than second and third groups (13.04 versus 11.5 and 11.7) and greater number of embryos transferred per cycle than second and third groups (4.12 versus 3.6 and 2.8).
The rate of pregnancy per transfer for the patients with hydrosalpinx was 12.5% versus 10.9% and 17.5% for the patients with tubal factor and male factor infertility.
Conclusions: Hydrosalpix did not result in impaired ovarian stimulation or decreased embryo transfer. We found no statistically significant difference in pregnancy rate per transfer between patients with hydrosalpinx and other patients.
