title: Utility of gonadotropin-releasing hormone agonists in programs of ovarian hyperstimulation with intrauterine insemination.
abstract: The GnRH agonists have practical and theoretic advantages for adjunctive use in ovulation induction. The IVF cycles demonstrate a decrease in the cancellation rate, an increase in the ease of scheduling, and an increase in the number of oocytes obtained per retrieval when GnRH agonists are employed. Other advantages, such as an improvement in the fertilization and cleavage rate, an increased length of the luteal phase, and an increased pregnancy rate, are suggested but not universally accepted. The utility of adding GnRH agonists to human menopausal gonadotropin-intrauterine insemination cycles is similarly in dispute. Although controlled ovarian hyperstimulation with both human menopausal gonadotropins alone and in conjunction with GnRH agonists have produced pregnancies when coupled with intrauterine insemination, it was demonstrated that there was a significantly greater pregnancy rate per cycle with the use of a GnRH agonist in a recalcitrant infertile population. Others did not substantiate this improvement in pregnancy rate per cycle in their patient population of regularly ovulating women undergoing their first controlled ovarian stimulation cycle either with or without GnRH agonist therapy. This suggests that women with ovulatory dysfunction, and particularly women who previously have not responded to therapy with human menopausal gonadotropin therapy, will reap the most benefits from the addition of a GnRH agonist to their ovulation induction regimen. The addition of a GnRH agonist to controlled ovarian hyperstimulation is a highly effective method of inducing pregnancy in a recalcitrant infertile population. Patients who did not conceive with human menopausal gonadotropins-intrauterine insemination may conceive with GnRH agonist-human menopausal gonadotropins-intrauterine insemination therapy.(ABSTRACT TRUNCATED AT 250 WORDS)
