ABSTRACT

Objective: To determine the cumulative clinical pregnancy rate in cycles of intrauterine insemination with gonadotropin stimulation in relation to number of mature follicles and age and the use of GnRH antagonist on its development.
Materials and Methods: Analytical, retrospective study in which intrauterine insemination cycles of patients with different gonadotropin protocols were evaluated over a period of two years. The patients were divided in two groups: ‹35 and ≥35 years old and the use of GnRH antagonist.
Results: We evaluated 229 cycles of intrauterine insemination in 172 patients; Of these 64% were under 34 years old (group 1) and 36% over 35 years. The use of antGnRH did not appear to have relation with better clinical and ongoing pregnancy rates in cycles with more than one mature follicle. The cumulative pregnancy rate in three cycles was 40.6%, and cumulative ongoing pregnancy rates was 26.1%.
Conclusions: The more mature follicle developed the higher clinical and ongoing pregnancy rates. The age did not appear to have influence in the pregnancy rates, there is no better pregnancy rates with use of antGnRH in cycles with multifolicular developed.
