  • New Concept in Oocyte Aging(Barad & Gliecher – Submitted for Publication 2012) Recruitment of more “young “ – chromosomally competent oocytes by altering internal follicular milieu Quality of oocytes Quantity of oocytes Quality of embryos Decreased Miscarriage Rates Improved LBR Page 22
  • Age DHEA IGF-1Low Androgen Levels Reduction of ApoptosisPoor Meiotic Activation of GC & TC FunctionCompetence Improved Mitocondrial Function Improved Steroidal Milieu Recruitment of young oocytesPoor Quality Ooocytes Normal oocyte maturation Page 23

  • Since first-trimester placenta produces DHEA , maternal DHEA exposure atmoderate dosages in very early pregnancy should not constitute significant risk(Loganath, A., Peh, K.L., Wong, P.C., 2002. Evidence for the biosynthesis of DHEAfrom cholesterol by first trimester human placental tissue: source of androgens. Horm. Metab. Res. 34, 116–120.) Page 27

  • •Delayed child bearing is the most important precipitating factor which increases the number of poor responders•Physiological rise in itnra-ovarian testosterone can be achieved with DHEA supplementation•Improved Ovarian Response to treatment can be expected with 3-4 months of DHEA in DOR •Robust evidences in terms of increasing LBR with DHEA treatment is still lacking•“ABSENCE OF EVIDENCE IS NOT EVIDENCE OF ABSENCE”•Role of CoQ10 & Folic acid in improving oocyte quality has to explored further Page 43
