IUI stands for Intrauterine Insemination. It is a fertility treatment that involves placing specially prepared sperm directly into a woman’s uterus around the time of ovulation. This increases the chances of the sperm reaching and fertilizing the egg naturally.
The process bypasses potential barriers in the cervix and brings the sperm closer to the fallopian tubes, where fertilization usually occurs.
When is IUI Recommended?
IUI is often the first line of treatment for couples facing:
-
Unexplained infertility
-
Mild male infertility (low sperm count or motility)
-
Cervical mucus problems
-
Ovulation disorders like PCOS
-
Ejaculation or sexual dysfunction
It’s also used in donor sperm insemination and sometimes with mild fertility medications to stimulate ovulation.
How Does the IUI Process Work?
-
Ovulation Monitoring:
The woman’s ovulation is tracked through ultrasounds and hormone tests. In some cases, medications are given to stimulate egg development. -
Sperm Collection & Washing:
The male partner (or donor) provides a semen sample. The sperm is then "washed" in the lab to remove weak or non-motile sperm, concentrating the healthiest ones. -
Insemination:
A thin, flexible catheter is used to insert the sperm directly into the uterus. The procedure is painless and takes only a few minutes. -
Pregnancy Test:
About 2 weeks after the procedure, a pregnancy test is done to confirm results.
💡 Benefits of IUI
-
Simple and non-invasive
-
No anesthesia or surgery required
-
Affordable compared to IVF or ICSI
-
Natural fertilization still occurs inside the body
-
Often recommended before moving to advanced treatments like IVF
What are the success rates?
IUI success depends on various factors like the woman’s age, fertility diagnosis, and whether fertility medications are used. On average, IUI success rates range between 10–20% per cycle, with higher chances when used in the right cases and age groups.
Is IUI Right for You?
IUI is a good starting point for couples seeking help with conception. It’s less invasive and more natural than other fertility treatments. However, if several cycles fail, your doctor may suggest moving to IVF or other advanced procedures.
