Table 1 Comparison between IVF cycles with hCG versus double trigger (GnRH-ag + hCG)

From: Co-administration of GnRH-agonist and hCG for final oocyte maturation (double trigger) in patients with low number of oocytes retrieved per number of preovulatory follicles-a preliminary report

  hCG Double trigger p values
Number of gonadotropin ampoules used 38.5 ± 24.5 49.8 ± 15.4 ns
Length of stimulation (days) 10.7 ± 2.5 10.7 ± 2.2 ns
Total number of gonadotropin used 39 ± 25 49 ± 15 ns
Peak E2 levels on day of hCG administration (pmol/l) 5402 ± 1983 4642 ± 2483 ns
