title: [INFLUENCE OF STIMULATION PROTOCOL ON MATURITY AND MORPHOLOGICAL FEATURES OF OOCYTES IN PATIENTS WITH LOW OVARIAN RESERVE: STUDY OF 72 IVF/ICSI TREATMENT CYCLES].
abstract: The current study presents the results of a retrospective and prospective observation of the maturity and morphological features of the oocytes and the way they are influenced by the therapeutic approaches and the protocol for controlled ovarian hypersimulation (COH) in patients with low ovarian reserve.
  
  
  METHODS
  The study includes 184 oocytes, derived from 72 patients with low ovarian reserve involved in an infertility treatment program through in vitro fertilization from February 2011 to February 2014. The applied therapeutic approaches and COH protocols are microdose agonist short protocol, antagonist short protocol, mild stimulation protocol and natural cycle in vitro fertilization.
  
  
  RESULTS
  Our study hasn't found a statistically significant dependence between the applied ovarian stimulation protocol and the maturity and morphology.
