I-31: ART Outcome in Endometrioma

Background: Our Background was to evaluate the effect of ovarian endometrioma on ovarian stimulation outcomes in Intra Cytoplasmic Sperm Injection (ICSI). Materials and Methods: In this prospective cohort study, we followed 103 patients underwent ICSI procedures at royan Institute during 10 month. The study group consisted of 46 women who had endometriomawith size more than 1 cm. The control group included 57 patients with male-factor infertility. The standard long protocol with gonadotropin-releasing hormone agonist (GnRH-a) and recombinant follicle stimulating hormone (rFSH) was used for ovarian stimulation. Two groups were compared for number of oocytes retrieved, oocytes grades, embryo quantity and quality. We also performed inter group comparison in patients with unilateral endometrioma.Results: There were no significant differences about basal characteristics between endometrioma and control groups. Our results also showed similar endometrial thickness, follicle numbers, and good embryo grades (grade A or B) in compared groups. Two groups had similar pregnancy rate. However, patients with endometrioma had higher gonadotropin consumption compared with control group. The mean number of retrieved oocytes in patients with endometrioma was 6.6 ± 3.74 compared with control group 10.4 ± 5.25 (p
