Intrauterine insemination

IUI is a fertility treatment in which sperm is injected directly into the uterus to increase the chances of fertilization.

Everything you should know about IUI

Intrauterine insemination (IUI) and artificial insemination through donor sperm (AID) are two common fertility treatments that can help couples achieve pregnancy.

In IUI, specially prepared sperm is injected directly into the uterus to bypass the cervix and increase the chances of sperm reaching the egg. The treatment is usually performed during ovulation, when the chances of successful fertilization are highest.

Before IUI, the partner's or a donor's sperm is processed to improve the quality and concentration of the sperm. The sperm are then taken in a small amount of fluid and inserted into the uterus through a thin tube. The procedure is painless and takes only a few minutes.

IUI may be recommended for couples in which the male partner has a low sperm count or motility, or in which the cause of infertility is unclear. Treatment may also be recommended for women in whom ovulation is irregular.

AID uses donor sperm to achieve pregnancy. The treatment is similar to IUI, but the sperm is provided by a donor. AID may be recommended for couples in which the male partner does not produce sperm or for couples who are at high risk of passing on genetic inherited diseases.

Both treatments are relatively simple and can usually be performed on an outpatient basis. However, success rates can vary from couple to couple and depend on various factors such as age, health status and the cause of infertility.

If you and your partner are having difficulty getting pregnant, you should consult a reproductive medicine specialist for further testing and to recommend appropriate treatment.


Cryopreservation allows the storage of eggs, sperm or embryos for later use.

Embryo transfer

Embryo transfer is the process of transferring a fertilized egg into a woman's uterus to enable pregnancy.
