Intrauterine insemination (IUI): definition

Intrauterine insemination (IUI) is a simple procedure that puts sperm directly inside your uterus, which helps healthy sperm get closer to your egg.

The hoped-for outcome of intrauterine insemination is for the sperm to swim into the fallopian tube and fertilize a waiting egg, resulting in a normal pregnancy. Depending on the reasons for infertility, IUI can be coordinated with your normal cycle or with fertility medications.

When does artificial insemination need to be used?

Artificial insemination is prescribed in the following cases:

  • Poor quality and insufficient number of sperm
  • Blocked sperm passage through the cervix
  • Difficulty ovulating
  • Failure of ovulation stimulation
  • Anomaly present in the cervix

What are the steps of the process?

Step 1: Previous tests necessary to artificial insemination

The recommended tests for performing artificial insemination are:

  • Hormone test to examine the ovarian reserve. The Anti-Müllerian Hormone (AMH) value can be determined at any time during the cycle, and the FSH and Estradiol value on day 3 of the cycle.
  • Semen analysis with motile sperm recovery (MSR) test to evaluate whether the partner’s sample is of sufficient quality to perform an insemination.
  • Gynaecological ultrasound to rule out uterine and ovarian diseases. It is also used to evaluate the ovarian reserve by antral follicle count.
  • Hysterosalpingography to evaluate tubal permeability. It consists of a contrast injection into the uterine neck while x-rays are being performed.
  • Serologies to rule out the presence of transmissible infectious diseases.

Step 2: ovarian stimulation

IUI combined with controlled ovarian stimulation (COS) is widely used because of the higher pregnancy rates compared to IUI cycles without COS. Controlled ovarian stimulation is performed by administering hormones through daily subcutaneous injections from the first few days of the cycle. The stimulation protocol will be individually adjusted according to the woman’s ovarian reserve.

Step 3: Sperm sample preparation

The procedure involves preparing the sperm cells to concentrate the most motile sperms for injection into the uterus. The goal of this is to increase the number of motile sperm cells that reach the eggs and subsequently increase the chances of fertilization.

The sperm wash involves removing the extra fluid, eliminating the dead sperms, weak sperms, bacteria, debris, and prostaglandins that can cause uterine cramps, at the same time concentrating the most motile sperms in order to ensure that a larger number of motile sperm cells reach the uterus.


Step 4: Insemination

Insemination of sperm can be done via cervical (CI) or intra‐uterine (IUI) routes:

  • Cervical Insemination (CI) delivers sperm directly to the cervix.
  • Intrauterine Insemination (IUI) bypasses your cervix, depositing sperm directly into your uterus.

It is recommended to take a urine pregnancy test two weeks after insemination.

How to Improve Artificial Insemination Success Rate?

The success of artificial insemination depends on more than the approach taken. Factors include:

  • a woman’s age
  • use of fertility medications
  • underlying fertility concerns.

According to a research study published in the journal Human Reproduction, the pregnancy rate for ICI is 37.9 percent after six treatment cycles. The same study found a 40.5 percent success rate for IUI after six treatments.

To increase the artificial insemination success rate, we recommend you to:

  • Continue a normal life
  • Practice physical activities such as yoga and walking.
  • Avoid alcohol

What are the side effects of artificial insemination?

During treatment, it is common for women to experience a number of undesirable but not serious effects (hot flushes, abdominal pain, nausea, vomiting, etc.). Some complications may lead to hospitalisation, such as ovarian hyperstimulation syndrome (OHSS).

Is artificial insemination painful?

Insemination is a simple and painless procedure, which is performed on a patient lying in the gynaecological position.

Should you have sex after insemination?

After artificial insemination, it is recommended to have sexual intercourse on the same day and the next day to enhance the effect of the technique.
