What is IUI?

Intrauterine Insemination (IUI) involves a laboratory procedure to separate fast moving sperm from more sluggish or non-moving sperm.

The fast moving sperms are then placed into the woman’s womb close to the time of ovulation when the egg is released from the ovary in the middle of the monthly cycle,  at around egg rupture .

Is IUI for me?

Our clinic may recommend IUI if:

  1. Cervical factor –
    a) Prior cervical treatment.
    b) Poor cervical mucus
  2. Mild to moderately abnormal semen analysis
  3. Oligospermia – low sperm concentration bet 5 to 10 million/ml
  4. Asthenospermia – low sperm motility between 20 – 50 %
  5. Decreased morphologically normal sperms
  6. Decreased total motile sperm values
  7. Unexplained infertility
  8. Grade 1 to grade 2 endometriosis
  9. Advanced maternal age – depending upon ovarian reserve
  10. Male ejaculatory dysfunction
  11. Use of frozen sperms
  12. Donor IUI for azoospermia
  13. Poor post coital test
  14. The presence of Antisperm Antibody.

How Does IUI Work?

IUI gives 8 to 18 % excess success rate above the natural conception. It augments sperm motility, helps to bypass vaginal passage if that area is creating problems for sperms entry in to the cervix.  


On Day 2 or Day 3 of menstrual cycle ovulation induction drugs are started (like tablets or Hormonal injections).
Close monitoring by ultrasound guidance on follicular growth is done.
Once follicle size reaches to 18 mm and above HCG Injection is given. 36 to 40 hours after HCG Injection IUI is done, after confirmation of ovulation.

Around the time of Procedure, you will be asked to produce a sample of sperm.
The sperm will be washed and prepared so the active, normal sperm are separated from the sample.
This washed sample is then introduced into the woman’s uterus with the help of a specific catheter.
