IUI (Intrauterine Insemination)
Intrauterine insemination (IUI) is a procedure in which washed and concentrated sperm are deposited directly into the uterine cavity via a thin catheter at the time of ovulation, bypassing cervical mucus filtration. IUI is less invasive than IVF and does not involve external fertilization. Fertilization, if it occurs, happens in the fallopian tube. Indications include mild male factor infertility, cervical factor infertility, donor sperm use, and some cases of undiagnosed infertility. Per-cycle clinical pregnancy rates vary widely by age, sperm parameters, and the underlying cause of reduced fertility. IUI bypasses the cervical environment. It does not correct what made that bypass necessary. Within RRM, IUI is not a restorative therapy. NaProTECHNOLOGY and NeoFertility protocols do not employ IUI. Instead, clinicians time natural intercourse to cycle-identified fertile windows and correct the underlying causes of subfertility in one or both partners.
