Natural Intrauterine Insemination (IUI) is a straightforward, unmedicated fertility treatment. It involves preparing a concentrated sample of semen and placing it directly inside the woman's uterus around the time of her natural ovulation.

By bypassing the cervix and vaginal acidity, Natural IUI shortens the sperm's journey to the fallopian tubes, boosting conception chances for couples experiencing mild male fertility factors or cervical mucus issues.

Since no ovarian stimulation medications are used, the risk of multiple pregnancies (twins/triplets) is identical to natural conception, making this a gentle and accessible first line of treatment.
