Diamond,

Here are some stats. They are old, but informative.

IUI-donor cycles
In 2004, in Australia and New Zealand, there were 3,170 cycles in which IUI using donated sperm (IUI-donor) was undertaken at fertility centres.
Of IUI-donor cycles, 12.5% (396) resulted in a pregnancy and 9.7% (307) resulted in a live delivery.
There were 24 (7.7%) IUI-donor cycles that resulted in a multiple gestation delivery.
Of babies born to women who had an IUI-donor cycle, 15.5% were preterm (<37 weeks gestation).
The average birthweight for babies born to women who had an IUI-donor cycle was 3,207 grams.
The perinatal death rate for babies born to women who had an IUI-donor cycle was 11.7 deaths per 1,000 births.

Earlier in this article they talked about IVF success rates. For women aged 23-24, the succes rate is 33%. For women 40-44 the rate is 7.1%.

For me, IUI has a lightly better success rate than IVF. The only reason why we might switch is because we want to try ICSI again. And go into financial distress.
