Intrauterine insemination (IUI), as a fertility treatment for lesser fertility issues, is applicable in legally married couple in Taiwan. With the technology of the ART, sperm is washed, separated, and concentrated to obtain high mobile and quality sperm. IUI is always used in conjunction with mild ovarian stimulation or ovulation timing, and the washed sperm is injected into uterine cavity through a transfer catheter.
The success of IUI depends on several factors including female age, ovarian function, semen and oocyte qualities, different ovulation inductors, and reason for infertility. If a couple has the IUI procedure performed each month, success rates may reach as high as 20% per cycle. In average, recipients will have 2~ 3 times of IUI to reach higher success rate. Those who did not conceive in 3 times of IUI should consider further advanced treatment.
