OBJETIVO: verificar se existe relação preditiva entre a contagem de folículos antrais (CFA) no segundo dia do ciclo com o padrão de resposta em ciclos de hiperestimulação ovariana controlada para injeção intracitoplasmática de espermatozóide (ICSI). MÉTODOS: estudo prospectivo, desenvolvido de maio de 2004 a maio de 2005, no qual 51 pacientes com idade 15 mm no dia do desencadeamento da ovulação, número total e em metáfase II de oócitos captados, número de embriões de boa qualidade transferidos e taxa de gestação. A análise estatística foi realizada pelos testes t de Student e de Mann-Whitney, com significância estatística de 5% (pPURPOSE: to establish whether there is a predictive relationship between the antral follicle count (AFC) on the second day of the cycle and the response pattern in controlled ovarian hyperstimulation cycles for intracytoplasmic sperm injection (ICSI). METHODS: a prospective study developed from May 2004 to May 2005, in which 51 patients aged 15 mm on the day of ovulation triggering, the total number of oocytes retrieved and in metaphases II, the number of good quality embryos transferred and pregnancy rate. The statistical analysis was performed by the t-Student test and the Mann-Whitney test, with statistical significance of 5% (p15 mm on the day of ovulation triggering (p=0.0001), the total number of oocytes retrieved (p=0.0001) and those in metaphases II (p=0.0001). Such correlation between AFC and pregnancy was not observed (p=0.43). There was no significant correlation between AFC and the number of good quality embryos transferred (p=0.081). CONCLUSIONS: AFC on the second day of the stimulated cycle can be used to predict the quality of ovarian stimulation, the number of oocytes retrieved and the number of mature oocytes in in vitro fertilization cycles using GnRH antagonist.
