Ovarian stimulation protocols (anti-oestrogens, gonadotrophins with and without GnRH agonists/antagonists) for intrauterine insemination (IUI) in women with subfertility.

Intrauterine insemination (IUI) combined with ovarian hyperstimulation (OH) has been demonstrated to be an effective form of treatment for subfertile couples. Several ovarian stimulation protocols combined with IUI have been proposed, but it is still not clear which stimulation protocol and which dose is the most cost-effective.
