Intrauterine Insemination (IUI)

What is Intrauterine Insemination (IUI)?

Intra uterine Insemination or artificial Insemination is a fertility procedure in which the washed sperm from a male partner is inserted into a woman’s uterus using a thin catheter once ovulation is detected. There are multiple factors which determine a successful outcome which is usually around 10% to 12% per cycle.

  • Stimulation Treatments

    The ovaries are stimulated with medication to promote the growth of follicles and this can be done by using both Tablets and Injections.
    There are many different types of stimulation Treatments

    Natural Cycle Insemination - This option doesn’t involve any medication and follows the women's natural menstrual cycle. This usually has low success rate.

    Clomiphene Citrate Ovulation Induction - This option involves the use of medication in the form of tablets to stimulate the ovaries.

    Gonadotrophin injection - This option involves the use of hormone injections to stimulate the follicles in the ovaries.

  • Cycle Monitoring through Ultrasound Scans

    The response of ovaries to the injections and medications can be monitored by doing serial Ultrasound scans.

    Ovulation Trigger: To assist with the final maturation of the egg from the follicle, an injection of Human Chorionic Gonadotrophin (HCG) may be given. This ensures maturation and release of the egg from the follicle.

  • Sperm Collection

    Using Partner's Sperm (Fresh Sperm) - An Abstinence of at least 3 days but not more than 5 days is required to collect an optimal sample for the processing of the IUI. The Sperm sample is analysed and processed to concentrate the motile sperm and remove debris and immotile sperm.

    Donor Insemination (Frozen Sperm) - In this procedure the Sperm sample is obtained from Semen Bank.

  • Insemination

    A concentrated washed sample of motile sperm is used for insemination. The final sample is gently inserted into the uterine cavity using a speculum and a disposable catheter to bypass the cervix. The insemination procedure is simple and usually painless and takes few minutes.

    Pregnancy test is performed two weeks after the insemination.

  • Key Facts

    In Normal Intercourse only about 15% of ejaculated sperm succeed in passing through the cervix. The mucous barrier that exists in the cervix reduces the number of sperm that can pass into the uterus and fallopian tubes following normal sexual intercourse. Where the male already has a reduction in sperm count and/or morphology, and/or its motility, this normal barrier reduces the yield of fertile sperm even further.
    The Success rates of IUI varies depending on multiple factors. The range is from 10% to 12% per cycle.

  • When is Artificial Insemination recommended?

    Artificial Insemination is recommended for couples experiencing any of the following:
    Unexplained infertility - (Documented ovulation, patent tubes and Normal semen analysis)
    Mild endometriosis
    Ovulatory disorder responsive to fertility medication.
    Problems with intercourse like Erectile Dysfunction, but potentially normal sperm production.
    Male partner is absent for long periods- sperm may be frozen
    Hostile cervical mucus

    IUI can also be recommended in cases where a woman or couple needs donor sperm.

    Donor sperm is needed in cases where the husband/partner:
    Is azoospermia (no sperm produced in Semen).
    Is a carrier of a hereditary disease.
    Has HIV.
    Is unable to produce sperm.

    Artificial Insemination or IUI treatment is not recommended for:
    Women over 38 years of age.
    Women with tubal blockage or severe tubal damage.
    Women with severe endometriosis.
    Cases where the male partner has a markedly abnormal semen analysis

  • When is Artificial Insemination Cancelled or Not recommended?

    Overstimulation - Some women may experience an excessive response by their ovaries to the fertility drugs. Ovarian hyperstimulation syndrome (OHSS) occurs in a minority of women who over-respond. Symptoms include severe discomfort, nausea, vomiting, abdominal distension and dehydration. It is important that you notify the clinic immediately if any of these symptoms occur during your treatment, as hospitalisation may be required.

    Multiple pregnancy - If there are too many follicles seen on ultrasound before the IUI is carried out, the risk of multiple pregnancy may be too high and the procedure may be cancelled.

    Failed procedure - In a small number of cases, it is not possible to place the catheter into position through the cervix, and the sperm cannot be inserted into the uterine cavity.
