PURPOSE: to report three cases of spontaneous gestation in women with polycystic ovarian syndrome (PCOS), that occurred in the months subsequent to transvaginal oocyte retrieval for in vitro maturation (IVM). METHODS: three infertile patients with PCOS, submitted to oocytes' IVM without previous ovarian stimulation, were included in the study. During the procedure of oocytes' collection, each ovary was drilled from four to eight times. RESULTS: none of the patients got pregnant with the IVM technique. Evaluating the cases' follow-up, in seven months after the procedure, the three patients got pregnant without the help of techniques of assisted reproduction, which resulted in three births. CONCLUSIONS: the multiple drillings in the ovary of these patients with PCOS, during the process to collect oocytes, may have contributed to their pregnancy in the months following the procedure.
