Intrauterine Insemination (IUI) is a fertility treatment where sperm is washed, concentrated, and placed directly inside a woman’s uterus around the time of ovulation. By bypassing the cervix, it shortens the sperm’s journey and increases the number of motile sperm that reach the fallopian tubes.
IUI is often recommended for couples or individuals experiencing:
- Unexplained infertility
- Mild male factor infertility (low sperm count or motility)
- Cervical factor infertility (hostile cervical mucus)
- Anovulation (ovulatory disorders, often paired with ovulation induction drugs)
- Use of donor sperm
For IUI to be successful, the woman must have at least one open, functioning fallopian tube, and the male partner must have a reasonable sperm count after processing.
IUI is less invasive and less expensive. Fertilization happens naturally inside the woman’s body (in the fallopian tubes).
IVF (In Vitro Fertilization) involves extracting eggs, fertilizing them with sperm in a laboratory, and then transferring the resulting embryo back into the uterus.
