13.2 Success Rate For ICI, IUI, ITI




Description

This article is from the Infertility FAQ, by Rebecca Smith Waddell bec@fertilityplus.org with numerous contributions by others.

13.2 Success Rate For ICI, IUI, ITI

Intra-cervical insemination (ICI): "Success rates with intracervical
insemination have varied widely, but unfortunately, only 10 to 15% of couples
will obtain a pregnancy following 4 to 6 well timed cycles of insemination."
From http://www.ivf.com//insem.html

Intra-uterine insemination (IUI): Searching through about a dozen
medical journal articles and a number of web sites resulted in a
rather wide-range of statistics. Basically the odds of success are
reported to be just under 8% and as high as 26% per cycle. The low
statistics are with one follicle, while multiple follicles resulted in
as high 26% success. Another influencing factor is sperm count. Higher
sperm counts increase the odds of success, however, there was little
difference between success with good-average counts and those with
high counts. The overall success rate seems to be between 15-20% per
cycle, judging from the articles which will be abstracted as part of
the IUI FAQ at http://www.fertilityplus.org/faq/iui.html. The rate of
multiple gestation pregnancies was 23-30%.

Intra-tubal insemination (ITI): Similar to IUI only the sperm is
deposited in the fallopian tube. Atlanta Reproductive Health Centre
reports only a slightly higher success rate with ITI over IUI, and a
great deal more discomfort to the patient. One journal article was
found, calling this fallopian tube sperm perfusion, suggesting that
this procedure doubles the chances of success. The citation is:

Fanchin R, Olivennes F, Righini C, Hazout A, Schwab B, Frydman R, A
new system for fallopian tube sperm perfusion leads to pregnancy rates
twice as high as standard intrauterine insemination., Fertil Steril
64: 3, 505-10, Sep, 1995.
