Combined treatment with gonadotrophin releasing hormone agonist and gonadotrophins in poor responders to hyperstimulation for in vitro fertilization (IVF): clinical and endocrine results.

Seventy three cycles of combined gonadotrophin releasing hormone (GnRH) agonist/gonadotrophin treatment for IVF controlled ovarian hyperstimulation in previous poor responders to standard ovarian hyperstimulation therapy are reported. Oocyte numbers obtained were better than the previous average results, but were similar to the previous best response. In general more oocytes than the previous mean could be expected but low order responders were not transformed into high order responders. Pregnancies did occur in this difficult group of patients but the rate was modest. Because of a reduction in cancelled cycles, patients might reduce their total costs in time and gonadotrophin used, however this treatment is not a panacea for the true low order responder.
