A new approach to the management of patients at risk of ovarian hyperstimulation in an in-vitro fertilization programme.
In this study, we report an alternative method of management of patients at a potential risk of ovarian hyperstimulation syndrome (OHSS) in an in-vitro fertilization (IVF) programme, by the use of gonadotrophin releasing hormone analogue (GnRHa). Thirty eight women considered at risk of this syndrome, having serum oestradiol greater than 4000 pg/ml following ovarian stimulation, received a GnRHa nasal spray for induction of the preovulatory endogenous luteinizing hormone surge for follicular maturation prior to oocyte recovery. Oocyte recovery (mean oocytes per cycle 18.60 +/- 4.79; range 15-35) and IVF were successfully completed in 27 cycles. Twenty six women had embryos replaced and 11 pregnancies occurred (28.9% per operation, 42.3% per replacement cycle). None of the patients developed OHSS. Where there is a risk of OHSS, the use of GnRHa to induce the preovulatory surge of endogenous luteinizing hormone for final follicular maturation provides a successful and more economical alternative to cancellation of cycles.
