ABSTRACT
OBJECTIVE@#To investigate the outcome of in vitro fertilization and embryo transfer (IVF-ET) in special infertile patients following modified super-long down-regulation protocol combined with human menopausal gonadotropin (HMG) stimulation.@*METHODS@#Ninety-nine special patients (42 with endometriosis, 35 with PCOS, and 22 with insufficient down-regulation) who underwent modified super-long down-regulation protocol in 2008 were retrospectively analyzed. Gonadotropin releasing hormone analogues (GnRHa, 1.5 mg) was injected intramuscularly in mid-luteal phase twice and HMG was started 25 days later after the second GnRHa injection. Conventional IVF-ET was performed as routine procedure. The clinical outcomes were compared with those of 122 similar patients in the same period.@*RESULTS@#After modified super-long down-regulation, (1) in endometriosis patients, the average gonadotropin (Gn) used was (32.33 +/- 15.11) ampoules, duration of medication was (10.57 +/- 1.88) days, the progesterone (P) level on hCG day was (0.78 +/- 0.44) microg/L, and the clinical pregnancy rate (CPR) was 73.8%; (2) in PCOS patients, the average Gn used was (28.57 +/- 12.07) ampoules, the duration of medication was (11.71 +/- 2.07) days, the P level at hCG day was (0.65 +/- 0.39) microg/L, and the clinical pregnancy rate was 65.7%; (3) in insufficient down-regulation patients, the average Gn used was (26.22 +/- 12.07) ampoules, the duration of medication was (10.01 +/- 1.77) days, the P level at hCG day was (0.71 +/- 0.50) microg/L, and the clinical pregnancy rate was 72.7%. Compared with patients using regular down-regulation protocol, the clinical pregnancy rate was improved significantly and the cost decreased obviously. The clinical pregnancy rate significantly improved compared with that of routine long down-regulation groups.@*CONCLUSION@#Revised super-long protocol plus HMG is a cost-effective controlled ovary hyperstimulation (COH) regimen for infertile patients with endometriosis, PCOS and insufficient down-regulation.
