Prolonged pituitary down-regulation with gonadotropin-releasing hormone agonist improve the clinical pregnancy rate in intrauterine insemination treatment

Abstract

Although GnRH agonist administration in the luteal phase has been documented not to improve pregnancy rate, it is not clear that does the use of GnRH agonist prior to the IUI treatment cycle in the early follicular phase improve pregnancy outcome in intrauterine insemination (IUI) cycles.
