This study found that the presence of ovarian endometrioma did not significantly affect the number of retrieved oocytes or metaphase II oocytes in women undergoing in vitro fertilization.

This paper studied whether ovarian endometrioma affects the number of oocytes retrieved during IVF. In the reported groups, endometrioma mean diameters were about 26.2±7.3 mm (right) and 23.2±6.1 mm (left), and the average number of retrieved oocytes was 12.4±8.3 versus 12.2±8.6, with similar counts of metaphase II oocytes (8.6±6.1 versus 9.4±7.3) between the endometrioma group and the comparator group. The authors reported no statistically significant differences for either retrieved oocytes or metaphase II oocytes (p>0.05). This paper is centrally about endometriosis—specifically whether ovarian endometrioma changes IVF oocyte retrieval numbers.

Abstract

ObjectiveTo investigate the effects of ovarian endometrioma on the number of oocytes retrieved for in vitro fertilization (IVF).BackgroundThe presence of endometrioma may be the most important predictor of a poor reproductive outcome. Literature data suggest that ovarian endometriomas might affect the response to ovarian stimulation and oocyte retrieval.MethodsThe present retrospective study evaluates 2,023 women who applied to our center with an infertility complaint. Twenty-nine women with endometriomas (group 1) who were treated with IVF were included in the study. They were compared with 51 women with unexplained infertility (group 2) regarding the number of retrieved oocytes after egg retrieval and number of metaphase II oocytes. The diagnosis of endometrioma was made via ultrasound examination with the identification of low-density cystic masses in the ovaries. The patients underwent a controlled ovarian hyperstimulation (COH) with either the long agonist mini-dose protocol or the multi-dose antagonist protocol.ResultsThe incidence of endometrioma in infertile women was found to be 1.4 %. The women's ages ranged between 24 and 45 years, and the duration of their infertility ranged between 12 and 216 months. The endometrioma was bilateral in 24 % of the cases. The mean endometrioma diameter was 26.2±7.3 mm for the right ovary and 23.2±6.1 mm for the left ovary. The average number of retrieved oocytes after egg retrieval in groups 1 and 2 was 12.4±8.3 and 12.2±8.6, respectively. The average number of metaphase II oocytes in groups 1 and 2 was 8.6±6.1 and 9.4±7.3, respectively. The number of retrieved oocytes after egg retrieval and the number of metaphase II oocytes in both endometrioma group and unexplained infertile group were similar (p >0.05).ConclusionEndometrioma did not reduce the number of retrieved oocytes in a COH cycle for IVF treatment. However it should be noted that the ovarian response is affected by the size of endometriomas, bilaterality, previous surgeries, recurrence, and the patient's age (Tab. 1, Ref. 31).
