Intrauterine Insemination (IUI)

Intrauterine Insemination (IUI)

Intrauterine insemination (IUI) is a fertility treatment in which processed sperm are placed directly into the uterus to increase the chances of fertilization. The procedure brings the sperm closer to the egg, improving the possibility that fertilization will occur.

In this method, motile (actively moving) sperm collected from the male partner are concentrated and then inserted into the female partner’s uterus. The procedure is usually timed to coincide with ovulation, when an egg is released from the ovary.

IUI is often recommended in cases where:

• The male partner has a low sperm count or reduced sperm motility

• The female partner has ovulatory dysfunction

• The female partner has mild endometriosis

• There are unexplained fertility problems

Is Intrauterine Insemination Suitable?

IUI can be an effective treatment for many couples when certain conditions are met. For successful IUI:

• At least one fallopian tube should be open and functional

• The female partner should have adequate ovarian function

• The male partner should have sufficient viable sperm

IUI may not be recommended in situations such as:

• Blocked fallopian tubes

• Very low egg reserve

• Severe endometriosis

• Advanced maternal age with reduced ovarian function

In such situations, more advanced fertility treatments such as in vitro fertilization (IVF) may be considered.

Steps of the IUI Procedure:

1. Ovulation Stimulation

Although IUI can be performed during a natural menstrual cycle, ovulation is often stimulated with medications to encourage the development and release of eggs.

2. Semen Collection

Around the time of ovulation, a semen sample is collected from the male partner. To improve sperm quality, 2–4 days of sexual abstinence before sample collection is usually recommended.

3. Sperm Preparation

The collected semen sample is processed in a laboratory. This procedure, often called sperm washing, separates the motile sperm from other components of the semen and concentrates the healthiest sperm.

4. Cervical Preparation

When the ovarian follicle is mature and ovulation is near, the woman is prepared for the procedure. A speculum is gently inserted into the vagina to allow access to the cervix.

5. Insemination

In the final step, the processed sperm sample is inserted directly into the uterus using a thin, flexible catheter. The procedure is quick and usually causes minimal discomfort.

IUI is a relatively simple and minimally invasive fertility treatment that may improve the chances of pregnancy when performed at the correct time in the ovulatory cycle and under proper medical supervision.
