Definition - What does Double IUI mean?
Double IUI (or double intrauterine insemination) is a procedure where sperm is placed inside a woman’s uterus on two days of her menstrual cycle. This is in contrast to a single IUI, where sperm is placed on a single day. The total number of sperm placed into the uterus in double IUI cycles is, therefore, higher than in single IUI cycles.
FertilitySmarts explains Double IUI
Double IUI may be offered to couples who have a hard time conceiving after at least one year of unprotected sex when the male partner is subfertile.
The correct timing of insemination accounts for the success of this procedure. When a double insemination is timed before ovulation, the success rates are higher. This is in contrast to the higher successful pregnancy rates achieved with a single IUI performed after ovulation.
When compared to IVF, double IUI is more cost-effective, with the cost of IUI being four to seven times less than the cost of an IVF treatment. However, it appears to be more costly when compared to a single IUI cycle.
For unexplained infertility (or when the reason for infertility cannot be determined), single IUI appears to be more promising than the double IUI.
