									Removal of Blocked Fallopian Tubes Improves IVF Pregnancy Rates

from Abington Reproductive Online (Abington's former newsletter)

In vitro fertilization (IVF) was originally designed for women with blocked fallopian tubes. IVF is now used successfully
to treat many other conditions, including endometriosis, unexplained infertility, male factor infertility, ovulatory dysfunc-
tion, and recurrent failed attempts using other fertility technologies. Recent research that we at Abington Reproductive
Medicine have participated in shows that removal of such tubes prior to IVF will increase success rates.

The fluid in the blocked tubes (hydrosalpinx) may have a deleterious effect upon the implantation environment inside
the uterus. Blocked tubes may result from infections (pelvic inflammatory disease, peritonitis), ectopic pregnancy,
endometriosis, and previous tubal surgery. Blocked tubes may be diagnosed by either a hysterosalpingogram or
endovaginal ultrasound or a laparoscopy.

Occasionally, laser or microsurgery may successfully open up less damaged tubes, however the more severely dam-
aged tubes should probably be removed. Removal may decrease chance of an ectopic pregnancy as well. The theory
is that if the tube is opened where it meets the uterus, but blocked at the far end, fluid may build up in the tube. This
fluid is then in constant contact with the uterine lining where the embryo would implant. In animal studies, this fluid has
been shown to be toxic to mouse embryos and prevents implantation of mouse embryos if injected into a mouse uterus.

Studies now conclusively prove that pregnancy rate will increase after these tubes are drained of their fluid or are
removed. The technique for removal of tubes usually involves an outpatient laparoscopic procedure. The recent data
shows that pregnancy rates double after surgical removal of the hydrosalpinges.

As always, your doctors at ARM are at the cutting edge of infertility advances and bring you the highest Pregnancy
rates. Ask your doctor for more information about this new approach to tubal blockage, especially prior to IVF cycles.
