IUI is one of the simplest forms of assisted reproduction, as there is no removal of eggs and no fertilisation in the laboratory. Sperm from the male partner, or a donor, is simply introduced into the uterus via a catheter and left to fertilise the egg or eggs naturally.
IUI is an ideal treatment for couples who produce healthy eggs and sperm, but who experience problems in conceiving through intercourse due to disability, injury, erectile or ejaculation problems. IUI using donor sperm can provide a route to conception for couples where the male produces no sperm at all, for single women, or women in same sex relationships.
