Is the use of a GnRH antagonist effective in patients with polycystic ovarian syndrome? A South African perspective
Abstract
Aim. The aim of this study was to assess whether there was a difference in the pregnancy outcomes of women with PCOS when a standard gonadotrophin-releasing hormone (GnRH) antagonist (cetrorelix) protocol was used for ovarian stimulation, compared with non-PCOS patients undergoing IVF.
Methods. A retrospective patient record audit was performed on 142 patients with PCOS and 501 non-PCOS patients undergoing a similar cetrorelix-based COS treatment protocol during a specified time period.
Results. The main primary outcome was an ongoing pregnancy at 12 weeks, achieved in 34% of patients in the PCOS group and 27% in the non-PCOS group. This was not significantly different (p=0.07). No patient in the PCOS group experienced severe hyperstimulation syndrome.
Conclusion. There was no significant difference in pregnancy rates in patients with PCOS undergoing GnRH-antagonist ovarian stimulation compared with non-PCOS patients. The fact that no hyperstimulation syndrome occurred makes this an attractive option for women with PCOS.
