title: "Ovarian age-based" stimulation of young women with diminished ovarian reserve results in excellent pregnancy rates with in vitro fertilization.
abstract: OBJECTIVE
  To determine whether pregnancy outcome can be positively affected if the ovarian stimulation in women with diminished ovarian reserve (DOR) is changed.
  
  
  METHODS
  Case control study.
  
  
  METHODS
  Medical school-affiliated private infertility center.
  
  
  METHODS
  Sixty-two women, aged 26-35 years, with the diagnosis of DOR (study group) and 62 age-matched controls with apparently normal ovarian function (control group).
  
  
  METHODS
  Study group patients received a modified (ovarian age-based) stimulation with microdose GnRH agonist (GnRH-a) and 450-600 IU of gonadotropin daily. Women in the control group received a standard "chronological age-based" stimulation with long luteal phase GnRH-a and up to 300 IU of gonadotropins (two patients in this group received an antagonist in place of an agonist).
  
  
  METHODS
  The IVF cycle outcome parameters, including pregnancy rates (PR).
  
  
  RESULTS
  Women with DOR and controls did not differ significantly in patient profiles or underlying infertility conditions and received identical embryo numbers at transfer. The DOR patients demonstrated a strong trend toward lower gravidity. Peak E(2) levels were similar between groups but controls produced significantly more oocytes, a strong trend toward more embryos and significantly more cycles of cryopreservation. Both groups achieved a 47% rate of first positive pregnancy test (hCG), with controls demonstrating a 39% and DOR patients a 32% ongoing PR.
  
  
  CONCLUSIONS
  Women with DOR, if treated with an ovarian age-based rather than chronological age-based ovarian stimulation protocols, will demonstrate surprisingly good PR with IVF in comparison to women with normal ovarian function.
